This week I was invited to Spirent Communications EMEA partner event in Valencia, as a guest speaker on evolving telecoms & networks - and the impact for suppliers of test equipment and network-assurance. The full day of presentations as background helped me hone my speech. (NDAs carefully observed in this post).
I’ve always found test vendors interesting, as they have a better view of the “real world” of telecom operators’ and enterprises’ upcoming deployments and launches than almost anyone else. Telco don’t put anything in the market without comprehensive testing first, especially given compliance risks as well as commercial ones. The event was a reality check – and eye-opener on some things I hadn’t previously considered.
Spirent mostly sells gear that emulates traffic or devices, to see if network equipment or software performs appropriately. For instance, an MNO might want to test several vendors’ 5G core networks in their internal labs, to compare performance, security and reliability. It is easier to use a box to mimic 100s of devices generating radio or core network requests, rather than racks full of physical smartphones instead. There are also test systems for Wi-Fi, enterprise network security (eg SD-WAN and SASE), O-RAN and various emerging 5G capabilities, including cloud-based elements, plus ways to automate the test and lab processes.
Two adjacent sectors speak to network testing outside traditional mobile networks, in areas that I’ve covered recently myself. It has specific systems for testing positioning and timing functions, especially those delivered from satellite. Think about GPS and various peers, and their importance to devices from smartphones to cars, boats and planes. Clearly you can’t put a physical satellite in your lab (or a constellation), so if you want to test a new device or complex system, you’ll have to emulate the satellite signals instead. Given the growing number of LEO and GEO providers offering positioning, connectivity etc, that’s an important test domain to consider.
Another new area is testing of networks used in AI datacentres. The scale and workloads mean the internal connectivity in DCs full of GPUs is different to that in conventional DCs – and again, these need testing before deployment. Again, it’s much easier if you can emulate a load of GPU servers in the lab, rather than run and configure/connect real physical boxes with all the cost and power implications.
My own speech covered my normal terrain – the telecoms downturn and future outlook, new stakeholders and models in networks (wholesale, #private5G, utilities, #neutralhosts), shifts in #spectrum & sharing between #5G, #WiFi, broadcast and defence users, coverage/performance needs in rural areas and indoors, virtualisation and disaggregation, APIs, the impact of AI on traffic patterns – and shifting regulation. All these will change and extend the testing landscape, I think.
Thanks for the invitation Lisa Elliott & Mark Bateman!
