I helped get a device through part15 testing during an internship and was shocked to find that you don’t need the same firmware (like at all. You can run totally different oses and everything, they don’t have to share a single line of code.) As long as you say “this is pretty much the same as what we’re shipping to users” you’re fine. They don’t really have anyway to double check it and to be honest I wouldn’t be totally surprised if a lot of devices used different power levels and generally behaved differently in the field just by mistake.
After doing that, when ever I hear about things being “tested” to standards from some arm of a government I instinctively think of that. I don’t know how you could practically improve on it either.

- soziawa 9y agoHuawei does this with their phones during rf emissions testing don't they? And the same is said about cars during crash tests.
- kokey 9y agoI know Huawei did exactly this when their phone network equipment was being tested for approval and adoption by mobile phone networks.
- dangrossman 9y ago> cars during crash tests The IIHS at least buys its cars from dealers like any consumer would, rather than getting them direct from manufacturers, to prevent them from sending specially modified cars for testing.
- bradfa 9y agoDepending on what rules apply to your particular transmitter and if you're not just doing FCC but also testing for other countries' standards, sometimes you cannot run the production software in order to actually test the radio as required. Granted, you're right, it's the honor system that what ships to customers works like the test subject did, but it's not always entirely due to malice.
- swiley 9y agoOh no, I wasn't saying it's malicious, just that many government tests work on good faith when you wouldn't necessarily expect it.
