I don't know how programmable Qualcomm's chipsets are, but in the case of a Broadcom-based router, the router manufacturer should be able to reconfigure any available channel and output power levels by compiling a new CLM file. This contains a table with all that power configuration data, and can be either embedded in the wireless driver at compile time, or loaded externally at boot time.now that the FCC does allow the same power in the lower segment of 5GHz. channels as the upper segment of 5GHz. channels, do newer routers like the Netgear R7800 take advantage of that? Can older routers take advantage of this via new firmware, or only newer routers? Not sure if the firmware that you can flash has control over radio power or not?
Tbe Veriwave is a very powerful system, but has three limitations when it comes to the type of testing we do. Its input range is limited to a 10dB range from around -25 to -35dBm. So it can't be used with external programmable attenuators for rate vs. range testing.I'm wondering why still use Chariot for 2x2 throughput testing since you already have IxVeriwave. Shouldn't keep the test bed as similar as possible ?
They would have to go back thru FCC testing again - most vendors likely won't due to cost concerns (very expensive)Any changes to transmit power levels require FCC recertification. I know of no older routers that have gone through the process. Please correct me if I am wrong.
New routers have been shipping with the new transmit power levels since the rules went into effect.
It's hard work - both for defining the test requirements, and also building the automation scripts behind it - been there myself helping out our performance test team.Load / capacity / stress testing is in the works. But need to work through some challenges with Veriwave and decide on the approach.
