said by wirelessdog:The 900mhz product is still crappy compared to Moto in terms of robustness in noisy environments but if you can get the signal down to -68 or better in a low noise environment the throughput is pretty amazing.
I'm thinking this is likely the result of legacy attributes associated with the 802.11a/b/g/n protocol. The collision avoidance logic might be in hardware or firmware. If you can't turn it off, the radios would shut down in a high noise environment. Just guessing though.
