Product update: INOS used in Pre-Launch Testing for Africell Angola Network

As part of the recent successful commercial launch of Africell Angola, the Digis Squared AI-tool INOS, powered by Intel® Xeon® Scalable Processors, was used as a key part of the network cluster testing and acceptance process. Digis Squared’s Key Account Manager for Africell, Ahmed Ma’moon, shares more.

“Digis Squared manages the entire end to end Managed Services for the new Africell Angola mobile network*. Ahead of the commercial launch on 7th April, and working closely alongside our partners, we ensured that the network was tested robustly before launch.”  [*Read more about that, here.]

“Whilst the capabilities of our vendor-agnostic tool, INOS, are extensive, in the pre-launch phase of the Africell Angola project, its major role was in field optimization following the SSV (Single Site Verification) and sites acceptance phase. The team used INOS devices out in the field in vehicles to collect network performance data for all live sites. We were able to optimise our resources too – thanks to the ability to remotely update scripts, we didn’t need to send engineers out into the field; the INOS kit can be driven to a specific location and along a predefined route by anyone, and the data is automatically uploaded into the cloud immediately.”

 

What is a mobile network cluster?

Mobile network coverage is often drawn as a honeycomb-like pattern of neatly meshing hexagons.

In reality, the coverage is not neatly tessellated hexagons, but very irregular shapes, due to the landscape, buildings and other features, and coverage from adjacent cells may overlap, or there may be some thin gaps. Mobile network planning engineers allocate different frequency bands (also called channels) to neighbouring cells – this helps to minimise interference even when coverage areas overlap slightly. The group of cells on different bands is known as a cluster.

 

INOS for Cluster Optimisation

Ahmed continues, “Working from Digis Squared’s offices, our engineers were able to control and update scripts remotely, push revised routes to drivers, and review data live in the cloud during the tests. During the pre-launch phase we ran field measurements using INOS for Luanda province clusters and sub-clusters, undertook the analysis to identify coverage issues, implemented optimisation changes live on the network, and then re-tested and benchmarked the results against the initial data.”

“INOS’ AI-capabilities ensure that analysis of vast amounts of data is completed very rapidly – within 15 minutes of uploading data – so we were able to assess the results, implement fixes and re-run the tests very swiftly.”

Comprehensive pre-launch testing to optimise for post-launch excellence

“INOS was a vital tool for us in the pre-launch field optimization activities for Africell Angola, to ensure best network coverage and performance, and excellent user experience after launch. INOS helped to speed up the field optimization process for all Luanda clusters, and complete the work in advance of the scheduled launch date.”

 

INOS & Intel

“INOS was a vital tool for us in the pre-launch field optimization activities for Africell Angola, to ensure best network coverage and performance, and excellent user experience after launch. INOS helped to speed up the field optimization process for all Luanda clusters, and complete the work in advance of the scheduled launch date.”

INOS can be implemented as a public or private cloud, or on-premise solution, and is also available as a “Radio Testing as-a-service” model. Its extensive AI-analysis and remote OTA capabilities ensure speedy and accurate assessment of all aspects of network testing: SSV, in-building and drive testing, network optimisation and competitor benchmarking, across all vendors, network capabilities and technologies, including 5G, private networks and OpenRAN.

INOS is built with compute resources powered by Intel® Xeon® Scalable Processors.
