“Connecting the world. As the UK expands its investment in STEM sectors, these firms are developing cutting-edge technology and building new ways to stay connected.”
This text is taken from a post by Business Insider / Insider Studios, which lists Digis Squared, what3words, CommAgility, pureLiFi and Speechmatics as five of the most innovative UK telecoms and technology firms. Read their full article here.
The telecoms and technology industries are likely to keep up their rapid rate of expansion over the next decade. This presents an opportunity for investment and development in the companies that are driving progress forward.
These 5 UK-based firms are highly innovative in their fields, from using light to enable wireless internet, to deploying artificial intelligence (AI), to removing bias in speech recognition. These are the companies whose pioneering technology will capitalize on an increasingly connected world.
Digis Squared enables telecom operators and communications service providers to optimize, upgrade, manage, and enhance their networks. Its clients include the likes of Vodafone, Telefónica, and Telecom Egypt, and it has offices in the UK, Egypt, and Dubai — as well as a new site in Luanda, Angola, which opened in October.
“Our new office in Luanda will on-board a team of over 40 engineers providing managed services for the entire Africell Angola network,” Mohamed Hamdy, the company’s chief commercial officer, said. The new office will also support “the commercial launch of [Africell Angola’s] new network to the public in 2022.”
Africa is a huge market for the firm, which also plans to open a new facility in Saudi Arabia in 2022. Key priorities for the year include expanding its footprint in its target markets and doubling its revenue. The rollout of 5G — and planning for 6G deployment — means the need for communication technology is likely to dramatically increase in both scale and complexity. This will lead to increased demand for Digis Squared’s services over the next five to 10 years, according to CEO Ziad Khalil.
“The ability for our business to work internationally is vital — communication is both constrained and unlimited by boundaries,” Hamdy added. “Digis Squared was set up as a multi-country operation and international trade has been at the heart of our approach right from the start. Working with DIT has been a key pillar of this.”
As new technology and demand for innovation leap forward, new ways to communicate will also need to accelerate. An international approach for telecoms and tech companies is crucial, and with support from the public sector to build relationships and provide investment, there is a bright future ahead.
The optimisation of capacity management in mobile networks is vital: too little capacity constraints revenue opportunities and impacts customer experience, but idle capacity risks high opex and under-performing investment in assets. Capacity management has always used mathematical modelling techniques to attempt to find the sweet spot, and optimise opportunities and costs. In the past, such predictions were based on historical data, but now AI enhancement of capacity management changes that. The deployment of network virtualization, 5G and network slicing requires the use of cognitive planning; it is vital that capacity planning models are able to assess a step-change in the volume of data points in real-time or near-real-time.
RAN Automation Architect and Data Scientist at Digis Squared, Obeid Allah Ali, describes how AI, automation and advanced analytics are being deployed to gain even greater network capacity planning efficiencies.
What exactly is machine learning, and why is it important?
Machine Learning (ML) is an application of artificial intelligence (AI) that enables computer programs to learn and improve over time because of their interactions with data.
It automates analytics by making predictions using algorithms that learn repeatedly.
Its easy self-learning technique, rather than rule-based programming, has found widespread use in a variety of contexts.
So, whether it’s making life easier with navigation advice based on predicted traffic behaviour, assessing large amounts of medical data to identify new patterns and links, or warning you about market volatility so you can adjust financial decisions, AI and ML technology has permeated many aspects of our daily lives.
The power of prediction machines
In simplified terms, prediction is the process of filling in the missing information. It takes the information you have, often called ‘data,’ and uses it to generate information you don’t have. Most machine learning algorithms are mathematical models that predict outcomes.
How will machine learning impact businesses?
There are two major ways that forecasts will alter the way businesses operate.
At low levels, a prediction machine can relieve humans of predictive activities, resulting in cost savings, and for example removing emotional bias.
A prediction machine could become so accurate and dependable that it alters how a company operates.
How big is the growth in mobile connectivity?
Some further statistics on the growth in mobile data, from the same GSMA report ,
global data per user reaching more than 6 GB per month – double the data usage for 2018
94% of the world’s population covered by mobile broadband network
By the end of 2020, 51% of the world’s population – just over 4 billion people – were using mobile internet, an increase of 225 million since the end of 2019
And from  GSMA Mobile Economy 2021 report,
By the end of 2025, 5G will account for just over a fifth of total mobile connections.
Capacity and performance of mobile networks
The rapid growth of mobile traffic places enormous strain on mobile networks’ ability to provide the necessary capacity and performance.
To meet demand, communications services providers (CSPs), mobile network operators and their suppliers need a range of options, including more spectrum, new technology, small cells, and traffic offloading to alternate access networks.
To meet commercial business objectives, mobile network operators are under pressure to maximize the utilization of existing resources while avoiding capacity bottlenecks that reduce revenues and negatively influence end-user experience.
Additionally, network operators have to assess risk, contractual SLAs (especially in the context of MVNOS who utilise their network, and corporate contracts), the total cost of ownership, and the impact on customer experience, perception and brand.
Radio Access Network costs are estimated to be 20% of the opex cost of running a network . And the impact of opex on network quality correlates strongly with increased ARPU and reduced churn; when network quality is highest, service providers benefit from a higher average ARPU (+31 %) and lower average churn (-27%) .
Finding the perfect balance of capacity, quality, efficiency and cost – not too much, not too little – is complex and dynamic.
Capacity forecasting for mobile networks
The Digis Squared team have developed machine learning algorithms and decoders that can, based on network activity, decode how User Traffic Profiles are changing. With the deployment of 5G and network slicing techniques, modelling network usage patterns and customer behaviour and predicting future demand becomes immediately far more complex – the only way to successfully model this will be with AI.
Detecting a problem
We detect anomalies in cells in the existing network, plus highly utilized cells, using machine learning and a design approach algorithm based on several reported KPIs. We use this information to distinguish what requires immediate attention from what should be monitored for proactive action. Using multivariable modeling techniques, that is, assessing multiple KPIs across each cell, enables us to have a highly nuanced model, optimising all available capacity.
Operators must be able to estimate the required traffic capacity for their mobile networks in this competitive climate to invest in extensions when they are truly needed, and deploy the most cost-effective solution, while maximizing investment and maintaining good network quality. In this phase of the development of the model, we will discover future troublesome cells to guide our approach and actions using predictive models.
AI enhancement of capacity management: what’s next?
Today, we use an open-loop control system to apply our AI methods. However, as predictive model accuracy improves, we anticipate transitioning to a fully automated Self-Organized Network (SON) – enabling closed-loop network management with self-planning, self-configuration, self-optimization, and self-healing – system in the near future.
In conversation with Obeid Allah Ali, RAN Automation Architect and Data Scientist at Digis Squared.
AI-native network slicing for 5G networks. Successful 5G deployments rely on the use and integration of many other new technologies. In this blog post, Tameem Sheble RAN data scientist at Digis Squared, and AI for 5G researcher, takes us on a deep dive through the close integration of 5G with AI, and how network slicing is vital to deliver the 5G vision.
The view from 2015: the 5G vision
New telecom technologies take years to be discussed, agreed and defined in standards. Previous wireless technologies have been designed and architected for one major use case: enabling mobile broadband.
During the development phase of 5G standards, by means of reaching consensus and aligning expectations, the International Telecoms Union (ITU) defined their framework and overall objectives of the future out to 2020 and beyond, in a vision document. As part of this workaround 5G architecture, they considered three distinctive, cutting-edge service verticals – enhanced mobile broadband, massive machine-type communications and ultra-reliable and low-latency communications – and their usage scenarios and opportunities for communications service providers (CSPs).
Network Slicing (NS) is one of the 5G key enablers. It’s a technique that CSPs can use to satisfy the different needs and demands of the 5G heterogeneous verticals, as illustrated below, using the same physical network infrastructure.
AI-native network slicing for 5G networks
Network slicing enables the virtual and independent logical separation of physical networks. It’s a technique used to unlock the value of 5G networks, by opening the possibilities for customer-centric services based on the demand on the network while managing cost and complexity. Consequently, vendors and standardization communities consider 5G NS a key paradigm for 5G and beyond mobile network generations.
Although the 5G NS process brings flexibility, it also increases the complexity of network management. The introduction of AI into the 5G architecture, AI-native, is motivated by the vast amount of unexploited data and the inherent complexity and diversity that requires AI to be deployed as an integral part of the overall system design. Although the rising temptation is to rely on AI as a pillar for managing 5G network complexity, in practical terms, AI and 5G are indivisible. They tend to converge from an application perspective, and they become two halves of a whole. AI’s value relies on 5G; for example; critical data-driven decisions need to be communicated with ultra-low latency and high reliability.
AI as a potential solution to network slicing
Let’s turn now to addressing AI in a nutshell for the management of the complex sliced 5G network, a complexity that relates to decision-making towards efficient, dynamic management of resources in real-time. CSPs need to leverage the use of the vast volume of data flowing through the network in a proactive way, by forecasting and exploiting the future system behaviour.
The management lifecycle of a network slice consists of four main phases,
Many researchers have proposed AI solutions that underline the first 3 phases, as the decommissioning phase doesn’t involve management decisions. Admission control and network resources orchestration are some of the key slice management functions that need to make slice-level decisions to meet their requirements, while simultaneously maximizing the overall system performance.
Looking at this in more detail, this is achieved by controlling a massive number of parameters as a result of uncovering complex multivariate relationships that are related to each other in time, geolocation, etc. Proposing an AI solution must be done case by case depending on problem formulation and framing, algorithmic requirements, the scarcity and type of data and the operational time dynamics.
AI for network slices admission control (Phase 1)
Admission control – during the slice preparation phase – is a very critical decision-making control mechanism, it ensures that the requirements of the admitted slices are satisfied. During this control mechanism, a trade-off between resources sharing and KPIs fulfilment needs to be tackled. The decision on how many network slices run simultaneously, and how to share the network infrastructure between those slices, has an impact on the revenues of the CSPs.
The trade-off is further complicated by variables that alter over time, which makes the optimization of revenue based on admitted slices a difficult task. This is where Deep Reinforcement Learning (DRL) approach comes into the picture.
In a nutshell, the DRL algorithm has to learn the arrival pattern of network slices and make, for example, revenue-maximizing decisions based on the current system utilization and the anticipated long-term revenue evolution. Once a network slice is requested, and based on the system current utilization, two separate neural networks are in charge of scoring the two actions (i.e., accepting or rejecting the request), where each score represents the revenue associated with each action. Based on the difference in scores, the action corresponding to the higher revenue is selected; the algorithm interacts with the system and evaluates the accuracy of the forecasted revenue through a loss function. This value is then feedback to the corresponding neural network to perform weight update, so that the algorithm starts converging to a global maximum and performs better in the subsequent request iterations.
AI for network resources orchestration and re-orchestration (Phase 2 and 3)
After the successful admission, slices must be allocated sufficient resources in such a way that the available capacity is used in the most efficient way that minimizes the operational expenses (OPEX). The trade-off here is between under-provisioning that leads to Service Level Agreement (SLA) violation, and over-dimensioning thus wasting resources.
CSPs need to be proactive by forecasting, at a slice level, the future capacity needed, based on previous traffic demand, and consequently timely reallocate resources when and where needed. This is where the Convolutional Neural Network (CNN) architecture comes into the picture for time-series forecasting.
Legacy state-of-the-art traffic time-series forecasting models focus on forecasting the future demand that minimizes some symmetric loss (e.g., mean absolute error), that treats both under- and over-prediction equally. But this type of legacy approach doesn’t consider the risk of under-provisioning and SLA violation – it is useless for 5G deployment!
Researchers argue that a practical AI-native resource orchestration solution has to forecast the minimum provisioned capacity that prevents SLA violation. The balance between over-dimensioning and under-provisioning is therefore controlled by the CSPs, by introducing a customized loss function that overcomes the drawbacks of the “vanilla symmetric losses”.
The AI literature proposes the use of 3-dimensional CNN architecture over the recurrent neural network (RNN) architecture – which is considered the state-of-the-art algorithm for forecasting time-series data – in order to exploit and uncover spatial and temporal traffic relationships.
The future for AI in 5G and beyond
Whilst general AI limitations are now well known – trustworthiness, generalization and interpretability – exploiting AI to assess and manage complex decisions is vital for the smooth operation of 5G networks. And as network technologies continue to grow in complexity and capability, AI will clearly be necessary as a pillar technology for future-generation zero-touch mobile networks
In conversation with Tameem Sheble RAN data scientist at Digis Squared, and AI for 5G researcher.
Digis Squared Chief Technology Officer, Abdelrahman Fady, shares insights into Digis Squared’s approach to cognitive solutions and AI.
“Today, there are three distinct and significant challenges that Mobile Operators face,
5G and new technologies are adding extra dimensions of complexity to the networks
Mature markets, ever-increasing customer expectations, and higher standards to reach for customer satisfaction
Revenues shrinking and increased budget pressures.”
“For sure, you can find an opportunity in every challenge,” shares Abdelrahman, “and here the opportunities we found within this complexity, pressure and maturity is the existence of massive amounts of data and very strong computational power. So let’s see how we can tackle these challenges using the created opportunities. This article digs into some answers!”
What is cognitive technology?
“Yes, it is software-based technology built on the 3Vs – volume, variety, velocity. Characteristics of big data lakes generated from networks, deployed over the strong computational power provided to us by new technologies, in combination with ML advanced modelling that fits in with SMEs unique logic.”
“Cognitive technologies refer to a multiple set of techniques, tools and platforms that enable the implementation of intelligent agents.”
Intelligent agent tasks can be considered as,
Think: Previous knowledge + known data
Intelligent agent thinking stakes: how cognitive agents work with ML & MR
“Cognitive computing represents self-learning systems that utilize machine learning, ML, and machine reasoning, MR, models to mimic the way brain works,” explains Abdelrahman.
The characteristics of cognitive computing include that they are,
Adaptive: cognitive software mimics the ability of human logic and brains to learn from and adapt to its surroundings
Interactive: cognitive solutions interact with all elements in the system (processors, devices, clouds and users)
Iterative: cognitive software always remembers previous interactions in a process
Stateful: cognitive solutions return suitable information
Contextual: cognitive software is capable of identifying contextual elements such as syntax, time, location, users, profiles etc
“Cognitive solutions nowadays are in the circle of focus of all mobile operators. Applying them in technical operations as well as commercial operations are likely to bring a lot of benefits to operators,” says Abdelrahman.
CAPEX rationalization: “Decisions about where to add new sites, layers, technologies, where and when to undertake network expansion should be taken based on many factors. ROI is part of this decision-making process, along with many other technical and commercial aspects, including the network growth and consumer behaviour changes, commercial positioning in the market, the general economic climate. Cognitive software like Smart Planning (Smart Capex) software ensure that proper investment and budgeting decisions are based on the complex interaction of such a diverse range of factors.”
Operational efficiency “Optimizing operations activities and resources are vital, and the hottest active topic these days due to the impact of COVID-19 on the overall telecom ecosystem. Automation has been used for ten years or more in the telecoms sector, however continuing to reach high efficiency targets needs more than just automation. It needs a combination of automation, AI, Big Data Analytics and human brain emulations, and this can only be achieved by deploying cognitive solution in operations.”
Superior network and customer experience “Smart Optimization for newly deployed sites, sectors and technologies are very important to enhance customer experience, and must work very swiftly to have impact. Additionally, network KPI enhancement plus handling customers pain-points before complaints arise or impact network churn KPIs are vital. It’s very important that all of these elements should be automated and continuously updated. To achieve that you must adopt smart cognitive solutions for network optimization.”
Fast time to market “Analysing consumer behaviour and response to what is offered by operators, as well as the impact of broader economic changes, help in the design optimisation of operators’ products and services. Because of the complexity of these inputs, the only way to assess the users and market needs is adopting cognitive technology in commercial analysis of client behaviour and product usage.”
Speedy mean time to resolve “Currently, mobile networks are very mature and very complex. In general, competitors are focused on customer centricity. Actually, this customer centricity couldn’t be in place without very accurate and decisive solutions that help us to identify and resolve network and customers’ technical and commercial issues and pain-points very quickly. This is one for the early targets achieved by the application of cognitive solutions and software.”
Cognitive technology limitations
“Having described and enthused about the benefits, lets provide some balance, and consider the limitations,” says Abdelrahman.
Handling un-expected risks and abrupt changes are the most serious challenges that face cognitive solutions. Due to slow response times to this type of change, cognitive solutions risk not being very accurate and speedy. Continuous development and training for adopted models in cognitive solutions is the only way to mitigate these challenges.
Data bias: as with any AI system, and mathematical model, bias is always dangerous. To mitigate this requires diversified data sources.
Decision accuracy is another challenge here which arises from the risk and possibility of mimicking the human brains of inexperienced team members. This risk may be mitigated easily by adopting a check-points technique during the solution design phase.
Explain-ability & repeatability: as with any AI system, it is vital that developers are able to explain how the cognitive system arrived at the answer it did. Decision tree mapping is a vital part of this process, as is the ability to explain and demonstrate why variability or repeatability does / not occur.
Data protection, data privacy and security are very important legal, regulatory and ethical factors, especially when you are dealing in your solution with personal data usage. Governments, regulators and authorities are putting a lot of effort into protecting consumer data, and customers are increasingly aware and vocal on the issue. One of the techniques which is often implemented to mitigate this risk is to mask any personal info with code like mapping.

In conversation with Digis Squared CTO, Abdulrahman Fady, we discuss mobile network technology sunset issues and opportunities.
As 5G rollouts gather pace globally, and new technology deployments continue their unstoppable march, many networks are also grappling with what to do about legacy technologies. In 1991 Radiolinja launched 2G in Finland, and 2001 brought the first 3G launch, achieved by NTT DoCoMo in Japan – both network technologies are still in active commercial use around the world, but for how much longer?
Abdulrahman Fady, CTO at Digis Squared, has worked in the technology sector for more than 20 years, and joined Digis Squared in 2018. In this blog post he shares his analysis of mobile network migration strategy and implementation in the context of network technology sunset issues and opportunities.
“Spectrum resources are finite, and operators wanting to launch new technologies need to either license new spectrum, if available, or re-allocate spectrum used for 2G and 3G. In most regions now re-allocation is the only option.”
“These old legacy technologies, 2G and 3G, they’ve been around for so long, that it’s tempting to think you could just switch them off and re-allocate the spectrum when utilisation drops below a certain threshold. But these old technologies continue to serve some really important markets. Firstly, low-income families often utilise older handsets which can only connect to 2G or 3G networks, and these provide a vital connection to the internet and mobile apps, across all geographic regions. These older handsets also tend to be simpler – appreciated by elderly users who don’t seek the complexity of smartphones.”
“And secondly, IoT. Early IoT deployments are often limited to only being able to connect to 2G or 3G networks, and physical replacement in many IoT use cases is frequently prohibitively expensive or geographically difficult.”
But some networks have already decommissioned their 2G networks – particularly Singapore, New Zealand and Australia. How did they achieve that?
“In Australia and New Zealand it’s the MNOs which have driven their 2G shut down. A low number of 2G M2M customers and the relative wealth of their consumer customers has mitigated most of their risks, but care still needs to be taken in this type of situation. If you are the first operator in a territory to switch off the old legacy network, you effectively force the churn of those 2G-only customers who won’t or can’t upgrade to your competitors – and so if you’re the last operator to switch off your 2G network, you might well have “acquired” all the low ARPU, low margin 2G consumers and IoT connections. Depending on the region, the regulator may intervene to force the maintenance of a rationalised legacy network, with lower capacity and coverage for low demand but critical IoT infrastructure, and vulnerable low income groups.”
“Other Asian countries have worked with regulator-led projects to decommission 2G, and reallocate network spectrum. But the commercial elements of these projects are not easy: M2M migration costs had to be negotiated in Singapore, New Zealand had to facilitate individual migrations, and continue to support a million smart meter connections.”
There are other commercial impacts too. “Mini-links and other microwave services on base stations were able to handle voice-only 2G and 3G demand, but when 2G and particularly 3G services are switched-off this drives an increase in demand for backbone services, and this in turn reduces the need for tower services, backhaul and transmission services.”
“In Europe, conversely, 3G networks are being turned off first, as there are a greater number of legacy M2M connections in the territory. These 3G devices can default down to the earlier 2G technology – a fallback strategy initially conceived to address coverage issues when 3G first launched, is now helping the more advanced technology become obsolete earlier!”
Partnering for change
“Whenever a network is switched off, the impacts on the remaining technologies will be considerable,” Abdulrahman explains. “Typically the switch off is more of a switch-over, as cell capacity is first reduced and then de-commissioned. Re-balancing and optimisation of the network loads is active and ongoing throughout the transition process, being undertaken with care to achieve minimum disruption. Working with strong, experienced partners in both the strategy and implementation phases, who can flexibly handle projects as unexpected issues arise, is crucial. Add multi-vendor network components into the mix, and the benefits of working with staff who have experience across all vendors and technologies can be vital to achieving a smooth network migration.”
“Whilst technology sunsets can initially seem complex, with careful consideration and planning, the process will deliver considerable benefits. The new network technologies reduce power usage and carbon footprint, and deliver enhanced speed, bandwidth and security. And, as day follows night, it is inevitable – it’s always better to be prepared and ready to make the most of the opportunity a new day brings!”

NB-IoT: Narrowband Internet of Things. One of two data networking technologies available on 4G (the other is LTE-M, aka CAT-M1). Intended for narrow band (250 kbps) low power data applications and does not support voice communications.
LTE-M: LTE Machine Type Communication. Also known as Cat-M1. One of two data networking technologies available on 4G (the other is NB-IoT). Provides considerably higher bandwidth (1Mbps), supports voice and full mobility.
In conversation with Digis Squared CTO AbdulRahman Fady, we explore some of the complexities and opportunities.
5G is a hot topic, with new handsets coming to market, and networks expanding globally. Abdulrahman Fady, CTO at Digis Squared, has worked in the technology sector for more than 20 years, and in this blog post he shares his views on how the deployment of this latest generation of telecom technologies will bring new problems to solve, and new opportunities to grasp.
So please share with us Abdulrahman, why is 5G so complex to deploy?
“By 2025, 5G networks are likely to cover one-third of the world’s population.”

5G rollout, complexity and issues
“Everyone is talking about 5G and how important it is for the ICT industry. Deploying 5G will change and benefit our societies, however, to deliver the real benefits of 5G a lot of challenges need to be addressed, starting with infrastructure and security, and expanding across all spheres into people culture and anthropology, and far from the expertise and competencies of the average ICT engineer.”
“I don’t think this will be an easy journey! It will be a really tough but exciting journey, where people have to learn how to implement adequate automation and AI techniques to make use of the data 5G delivers – it simply won’t be possible to assess the volume of data without AI. Technically, I believe there will be a strong competition between legacy RAN vendors and O-RAN vendors as they compete for market leadership – this will deliver benefits for operators and CSPs, and drive innovation and identification of new efficiencies.”
5G & IoT: “many of its technical capabilities have been designed with Industry 4.0 applications in mind:
Ultra-Reliable Low Latency Communication (URLLC) is vital for real-time communications between machines
Greater bandwidth and support for higher device density enables use cases that generate more data traffic and host a greater number of devices or sensors
Network slicing allows virtual separation of networks, enhancing security and reliability
Mobile Edge Computing allows critical network functionality to be retained at the edge, further enhancing resilience and operational continuity”
Source: GSMA 
“In the field of IIoT and C-IoT, I think there will be a lot of new ideas generated as nerds and ICT people get their hands on 5G tech. As these different approaches come together – the nerds exploring what the new tech and new devices can do, and ICT staff searching for solutions to address specific issues – they will bounce ideas of each other, and there will be real energy and dynamism as they race to bring new innovations to market.”
“5G will be a huge opportunity for the big cloud providers like Amazon, Google and Microsoft to change the way MNOs work, delivering massive real-time analysis capability, new opportunities for collaborative international teams to work together, system resilience and efficiency.”
“However, it’s not all good news! I think 5G security will be a showstopper in many countries, limiting the deployment of all its functions in some places. These issues will in turn bring great opportunities for third parties and SIs to play a far bigger role in the ICT ecosystem.”
The biggest issue
“But do you want to know the biggest issue I see? The number one challenge limiting 5G spreading swiftly worldwide, and blocking the real benefits of 5G deployments, is the complexity of handsets, the UEs and terminals.”
MIMO (Multiple Input Multiple Output) “MIMO has been used in wireless communications for a long time now — it’s common for both mobile devices and networks to have multiple antennas to enhance connectivity and offer better speeds and user experiences. MIMO algorithms come into play to control how data maps into antennas and where to focus energy in space. Both network and mobile devices need to have tight coordination among each other to make MIMO work.”
Source: Qualcomm 
5G uses Massive MIMO and expands on the existing MIMO systems, by adding a much higher number of antennas on the base station – this helps focus energy, which brings massive improvements in throughput and efficiency. As well as all the additional antennas, both the network and mobile devices implement more complex designs to coordinate MIMO operations.
5G utilises different parts of the radio spectrum to deliver performance, capacity and coverage
mmWave spectrum: best for dense urban areas and crowded indoor environments. Doesn’t travel very far, so an array of antennas is used for beamforming, which concentrates the radio energy to extend the range.
sub-6 GHz spectrum: best for broad 5G coverage and capacity with faster, more uniform data rates both outdoors and indoors for more users, simultaneously.
“5G handsets are super-sophisticated: they need to support Massive MIMO techniques, along with beamforming, sub-6GHZ bands, and mmWave for mobile. Designing all of this to work together is putting real pressure on antenna and RF designs – and then the ultimate challenge, physically fitting all of this into a beautiful handset design!”
“And if that’s not complex enough, we all expect our mobile devices to have incredibly efficient batteries, and yet remain small and lightweight, and deliver performance enhancements across 4G, 3G and GSM. You need very strong modems and processors deployed inside 5G handsets – and all of this in addition to the complexity 5G adds to software, OS and Kernel layers. That’s why it is not an easy job to deliver high-end 5G handsets!”
“There are many challenges, opportunities and battles to come as 5G rollout continues, and it will also create real opportunities and big returns if you have positioned yourself and your company right within the ecosystem.”

CSP: Communications Service Providers
ICT: Information and communications technology
IIoT: Industrial Internet of Things (interconnected sensors, instruments, and other devices networked together with computers’ industrial applications, including manufacturing and energy management)
Massive MIMO: a set of multiple-input and multiple-output technologies for multipath wireless communication, in which multiple users or terminals, each radioing over one or more antennas, communicate with one another.
O-RAN: Open RAN – via standardised radio interfaces and interoperability, hardware and software components from multiple vendors operate over network interfaces that are “open and interoperable”
Is this the perfect storm of telecoms technical complexity?
As network deployments get more complex, capacity management more difficult to predict, and customer demands rise, how can Telecoms Regulators help deliver the best customer experience?
Globally, 5G deployments are picking up pace, and 2G and 3G networks starting to be retired – engineers at MNOs and CSPs* are knee-deep in complexity, managing technology sunset strategies, IoT connectivity migrations, and adding new layers of 5G components into the patchwork of systems from multiple vendors. This activity brings with it more new operational systems and alarms to integrate (and disentangle), and extra work to try to bring everything together into a cohesive system.
On top of that, the operational teams within MNOs and CSPs have been working hard this year to reconfigure networks to handle shifts in demand, as the pandemic forces huge numbers of people to suddenly work and study from home, and unpredictable demand patterns are addressed as best as possible.
Is this the perfect storm of telecoms technical complexity? How should Telecoms Regulators respond and ensure customer Quality of Experience and Quality of Service are maintained? With so many technical changes occurring in a short space of time, how can technical regulatory staff keep pace with technology, anticipate the future, and ensure their knowledge-base remains unbiased?

Competence development to keep pace with new technologies.
“The Digis Squared team has a depth of experience and knowledge of implementations that you only acquire through years of working on difficult projects and tricky technology deployments. The team bring these insights to all their work, whether that’s with MNOs, CSPs or Regulators.“
Independent tools for QoE & QoS network benchmarking
Regulatory coverage and performance concerns vary by market, but in general fall into 3 distinct areas,
Many telecom network licenses have requirements to achieve specific KPIs: Geographical coverage, data throughput rates, QoS requirements.
Legacy benchmarking solutions are often expensive, no longer supported by the vendor, and have a long and slow process to deliver the final report.
When the report is eventually available, it is often a readout of dry statistics, with no clear recommendations on improvements. And with multiple solutions from multiple vendors implemented across the MNOs and CSPs in your territory, there is no standard process to rank and compare network operators.
Since the inception of Digis Squared the leadership team decided to invest and develop its own in-house, vendor-agnostic, multi-technology and scalable automated solutions, to ensure its staff and clients have access to vendor-independent assessment and testing of networks. Today, we are able to provide our clients with these tools to ensure they have an independent assessment of network capabilities. MNOs use our tools to help them accelerate network upgrades and network transformation, ensuring they are able to manage their network traffic growth and network complexity efficiently. Regulators use our tools to ensure they have the insights they need to assess KPIs independently.

In the last quarter of 2019, the number of 5G subscriptions had more than quadrupled to reach at least 17.73 million (1), and the GSMA was forecasting that “…2020 is set to prove the year for mass-market adoption around the world” (2). Although forecasts have changed, 2020 is still the year to build 5G, its capacity and robustness is needed now more than ever.
Covid-19 & 5G rollout
At the start of the Covid-19 crisis, as workers and students rapidly adjusted to working from home where they could, mobile data demand shifted rapidly and operators worked hard to keep pace. Some demand was displaced to fixed broadband and fibre connections, whilst others used mobile data to deal with competing demands of online gaming and video calls within the same household.
Even at the start of the crisis, a European IT Buyer Sentiment Survey conducted by IDC revealed that “58% of spending on 5G technology will be increased or will remain the same”, (3).
Now, as the pandemic continues to disrupt lives and society globally, with staff and students continuing to work and study from home, high speed, reliable connectivity has become essential. Home broadband has often struggled to meet demand, and 5G can often provide a better, more reliable and stable solution. As mobile network capacity has flexed to try and address the unpredictable demand, end customers have been very aware of which powerful, flexible and stable networks have adapted to meet their needs. 5G’s ultra-low latency and high-reliability has ensured that those customer’s with the ability to access it, have benefited from an excellent customer experience.
“5G will play a critical role in the digital economy for decades to come. This new era of intelligent connectivity offers the chance to recast customer value propositions, accelerate industrial transformation, and reinvigorate the digital society.”

In the initial stage of the pandemic, many mobile network operators and service providers put their investment plans on hold, realigning resources to meet the immediate needs of network re-dimensioning. Now, as the world starts to address mid to long term strategies, mobile operators and service providers are re-considering their 5G plans. As IDC portray in their graphic below (3), as we move forward through the different economic phases ahead of us, business focus changes.
Today, as business confidence slowly rebuilds, and commercial activity picks up pace, adjusted 5G strategies and rollout plans are progressing. As this GSMA map illustrates, as of June 2020, there are now 79 commercial launches globally.
Digis Squared, independent telecoms expertise
In the months ahead, as we move through the cycles IDC identifies, our experienced, independent and multi-vendor team at Digis Squared can help and guide your teams as they,
Reassess and revise technical and commercial network strategies, and budgets
Reconsider network vendor selection options commercially and technically
Review and revise rollout plans to address changes in working patterns, shifts in geographical demands and deliver extra flexibility for the future
Re-test and optimise existing network infrastructure, to ensure your existing investments are working as effectively as possible.
Perhaps, Communications Service Providers (CSPs) or Mobile Network Operator, you are considering whether to roll out 5G at all, and want to better understand how you can utilise your existing technologies for longer. We can help you assess this, and dimension your legacy infrastructure and licenses to optimise their use for a longer than originally anticipated lifespan.
Other businesses are experiencing supply chain disruption and bottlenecks in raw material access, production, and distribution. These, in turn, may cause you to re-assess commercial contracts and technical options – our teams can help you understand options and impacts, and ensure you have the flexibility and capability to be as ready as possible for whatever happens next.
As 5G rollout plans change and flex in ways we never envisaged, now more than ever, work with flexible partners to support your changing needs and deliver robust 5g capability.
