Open Source in Telecom Testing: Where srsRAN, OAI, and Amarisoft Fit
Open-source stacks changed what SDR-backed testing can do. Here is how they fit into a modern cloud tester and where a commercial stack still adds value.
It is impossible to talk seriously about SDR-backed conformance without talking about the open-source stacks that made it possible. srsRAN, OpenAirInterface, and the commercial descendants that grew out of both are the reason cloud testing is viable in 2026 at all.
The core difference: we ship a digital box, not a physical tester
Every legacy vendor in this market — Anritsu, Keysight, Rohde & Schwarz, Spirent, VIAVI — sells a physical box. You buy it, you rack it, you power it, you maintain it, you rent floor space for it, you keep engineers around who know how to operate it, and every time 3GPP releases a new specification you either wait for a firmware update or you buy another box. That model made sense in 1998. It stopped making sense the moment SDR became stable, cloud became universal, and every serious engineering team started living inside a browser and a git repository.
AEON Cloud is not a physical tester. We do not ship you hardware. There is nothing to unbox, nothing to rack, no shipping crate, no calibration ticket, no service contract on a chassis. What we ship is a URL. Your team opens the AEON Cloud web application from any laptop in any office, uploads a UE build, and executes real 3GPP TTCN-3 conformance campaigns against real SDR-backed radio lanes that we operate on your behalf. The tester exists — the antennas, the shielded enclosures, the LimeSDR and Ettus B210 boards, the ATS and the SS — but it lives in our racks, and you reach it through the same browser tab you use for GitHub.
That single architectural choice changes everything downstream: procurement becomes a signup instead of a purchase order, capacity becomes elastic instead of fixed, upgrades happen server-side instead of on a truck, teams in three time zones share the same lane instead of fighting over one chamber, and CI systems can trigger conformance runs the same way they trigger a unit test. Nothing to install. Nothing to maintain. Just a browser and a build.
What open source did for the category
Open source is the reason a small team can stand up a functional 5G stack on commodity SDR in a matter of weeks rather than years. It is the reason vendors like AEON Cloud can build a service without also having to build a full protocol stack from scratch. It is the reason academic labs and startups can experiment at the same layer that used to require an eight-figure vendor relationship.
Where a commercial stack still adds value
Open source gets you eighty percent of the way; the last twenty percent — the exhaustive Release 17 coverage, the pinned determinism, the operational discipline required to run a lane pool with SLAs — is the work a commercial platform absorbs on your behalf. AEON Cloud stands on the shoulders of the open-source ecosystem and adds the layers a customer needs to trust a verdict.
How to try this on AEON Cloud
If you want to see an open-source-derived lane running against your own UE build without buying, renting, or shipping any hardware, the fastest path is to create a free workspace, upload a build artifact, and reserve a lane from the browser. The entire loop — from signup to first verdict — is designed to complete in an afternoon, not a quarter.
Because the tester is a service rather than a device, you never have to plan around a hardware refresh cycle. When 3GPP publishes a new release, the catalog updates server-side and every workspace sees it the next time they log in. When a new SDR generation lands in our lab, your existing campaigns benefit from the improved fidelity without a purchase order.
