From Field Trials to Field Confidence: Log Replay in a Digital Lab
Field logs are a goldmine that most teams cannot exploit because they cannot replay them in a controlled environment. Cloud replay changes that.
The most valuable data any UE team generates is field data. It captures the messy reality of live networks that no lab can fully reproduce. Historically that data was underused because there was no controlled environment to replay it in. Cloud testers change the equation.
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.
How replay works
A field PCAP is uploaded to AEON Cloud. The platform reconstructs the relevant signalling flow, drives an SDR-backed lane with the appropriate stimuli, and runs the same UE build under the same conditions. The verdict either reproduces the field failure — in which case the team now has a controlled repro they can iterate against — or it does not, which itself is a useful signal about which layer the field issue actually lives in.
How to try this on AEON Cloud
If you want to see field-log replay 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.
