LTE 600MHz ◦ Network benchmarking & optimisation with INOS

Posted on by admin

The background: why is the 600MHz band being used for LTE?

Mobile data usage continues to grow throughout the world, and the pandemic has massively impacted forecasts and expectations, causing telecom operators and CSPs to bring forward their deployment decisions.

“The limited amount of spectrum available below 1 GHz will ultimately run out of capacity. This puts mobile broadband at risk in emerging markets, rural areas and inside buildings. Therefore, long-term
planning is key to enable countries to offer great mobile services for everyone.”

GSMA, October 2019

So what can be done to identify more spectrum for mobile broadband? Countries working on the digital TV switchover can consider including 600MHz for mobile broadband. North America is leading the way – USA auctions were completed in April 2017, Canada in April 2019, and Mexico in 2020!

600MHz LTE benefits

We asked Amr Ashraf, RAN and Software Solution Architect and Trainer at Digis Squared, to give us his insights into LTE 600MHz band.

“Over the last couple of years we’ve been starting to hear about the deployment of very low band for mobile communication.  Now, we have commercial networks working on one of the most important low bands, 600MHz.”

Halberd Bastion [2]: Band 71 600 MHz LTE coverage prediction

“600MHz is likely to need about 0.8 cells to cover the same area as a 700MHz cell. So 600MHz will be excellent for providing coverage over a given area. And, as an added bonus, the 600MHz signal is likely to penetrate most buildings – great for indoor coverage.”

“Ideally, an operator will have a selection of low band (600MHz, 700MHz and 90MHz) spectrum to provide wide coverage and in-building coverage together with higher bands (1.8GHz, 2.1/2.6GHz, etc.) to provide capacity at specific locations with small cells, including in-building distributed antenna systems. The trick is in deploying the bands efficiently and economically to meet the market needs.”

… and issues

“On other hand, I don’t think that the 600MHz band will be that useful for 5G implementation, as we can’t use all the new transmission techniques with a low band like Massive MIMO.”

“In order for MIMO to work effectively, the antennas need to be spatially separated such that they are uncorrelated. And, the lower the band, the larger the antenna and the required separation between them. At the 600MHz band, it would be incredibly difficult to physically fit more than two uncorrelated antennas inside handsets, given their current sizing. Our calculations therefore assume that 5G and 4G in the 600MHz band will only make use of 2×2 MIMO.”

“There will be some problems to be faced in the reallocation of systems currently utilising this band, like DTV, and also some wireless devices like MICs. However, 600MHz LTE will be one of the most important bands during the next 10 years for full 4G coverage, particularly for rural areas.”

What problems are encountered deploying the 600MHZ band?

With any new network deployment, testing and optimisation are vital to ensure network performance, and also address any inadvertent impacts on existing networks. Whilst a limited number of activities can be undertaken centrally, drive testing, and in-building testing are critical to understanding the real customer experience in the field.

Developed in-house by Digis Squared, INOS is an intelligent, automated testing, benchmarking and analysis platform for network operators and service providers, delivering drive testing (DT), in-building solution (IBS) capability, and much more, whilst decreasing both the time taken to complete the work and opex cost.

Using cloud-controlled mobiles mounted in cars or taken around buildings, INOS collects and uploads data to the cloud, and eliminates the need for a laptop or engineers in the car, or out and about inside buildings. INOS can receive updated test scripts in the field to instantly re-analyse live network configuration changes, avoiding expensive follow-up field trips. It minimises the sometimes chaotic nature of drive tests, and ensures your staff can work alone at Covid-19 safe distances.

One of the key issues with any drive testing tool, such as INOS, is that there are very few mobile phones available for drive testing in this 600MHz LTE frequency, and where there are, drive test solutions don’t use them.

The good news: uniquely, INOS supports LTE 600MHz band

The Digis Squared team have extensively tested a large range of mobile phones, and the best-performing mobile in the LTE 600MHz band that we have found so far is the Google Pixel 5.

After detailed testing in specific locations where 600MHz LTE is in the live network, our teams have found a significant enhancement in capability using this device in our testing portfolio.

5G ◦ Why is it so complex to deploy?

Posted on by admin

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.”

Source: GSMA [1]

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 [2]

“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 [3]

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!”

Opportunity

“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.”

Regulators ◦ Now more than ever, use independent tools and expertise

Posted on by admin

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?

Digis Squared has over 50 industry experts with 10 or more years’ multinational mobile operator and vendor experience.

Use our expertise to work alongside your teams and augment their skills and capability,

  • Independent tools for QoE & QoS network benchmarking
  • Band & spectrum strategy consultation
  • 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.“

Mohamed Hamdy, Digis Squared CCO

Independent tools for QoE & QoS network benchmarking

Regulatory coverage and performance concerns vary by market, but in general fall into 3 distinct areas,

  1. Many telecom network licenses have requirements to achieve specific KPIs: Geographical coverage, data throughput rates, QoS requirements.
  2. Legacy benchmarking solutions are often expensive, no longer supported by the vendor, and have a long and slow process to deliver the final report.
  3. 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.
