"I may piss off Qualcomm." These notes are from one of the world's top wireless researchers. I asked for help understanding the battle over telcos taking a large chunk of Wi-Fi spectrum. He's a good guy. If I pressed, he would probably go public.
Instead, I decided to write the article without his name after three other researchers also refused to go on-the-record. This is the power of companies worth $300B when they go all out. Several very good engineers have spoken out, including a Stanford prof. I could have gone to them but instead sought out experts I haven't seen publicly discussing the subject. If any reader with wireless expertise can help me out, on or off the record, I'd welcome it. In particular, if you think -72 dBm testing will eliminate most interference, please let me know.
His first comment was, "I would lean towards a -87 to -90 dBm threshold as being the appropriate level to avoid wifi interference to a significant number of wifi users."
