But under the new FCC rules, I assume the closer you are to the band edge, the more the severe the OOBE requirement becomes.
Could this be the start of equipment with additional hardware for a dynamic OOBE xmt filter to meet the FCC requirements? Whereas airPrism only filtered the rcv signal? What about Cambium 450i, anyone know if it filters both xmt and rcv? I wonder if WiFi gear will do this as well? Perhaps no, given the cost sensitivity, and that it wouldn’t help unless the client device also had it. But it seems like a sure winner for LTE-U/LAA. Trivial addition to an LTE basestation cost, in fact maybe they already have that capability for licensed band operation, surely they are not using WiFi chips. And no need to add anything to the client device because it doesn’t xmt in unlicensed.

That is pretty narrow banded for a modern power amplifier device. From: Peter Kranz Sent: Saturday, October 10, 2015 11:21 AM To: af@afmug.com Subject: Re: [AFMUG] UBNT Next try There is some interesting information in the Transmitter PSD chart in regards to OOBE limits. “The EUT was set to transmit on the lowest, middle and highest frequencies at the maximum power level” It shows using the same (25dBm) power level at 5735 and 5840 which I believe was not possible with the previous hardware. It looks like it supports full power across the band. -PK
