That doesn't sound right. If the Part 101 system is on a 60 MHz channel, that's all that should be blocked out. Maybe one adjacent channel each side for OOBE?
I'm not expert on how AFC works, but there's a lot of spectrum in U-NII-5 and U-NII-7, I can't believe AFC would block out most of it unless there are a bunch of priority users within range. Maybe contact Richard Bernhardt at WISPA. Or Cambium uses Qualcomm for AFC, contact them, maybe they will investigate. If they can't fix it, maybe they can tell you why. -----Original Message----- From: AF <[email protected]> On Behalf Of Dev Sent: Wednesday, July 23, 2025 5:26 PM To: [email protected] Subject: [AFMUG] challenging AFC 6Ghz? We have a Cambium ePMP 4600 4x4 90 deg sector sitting 5 mountain tops from the nearest 6GHz point source, but straight-line but AFC thinks it might interfere (I guess), which could only happen on flat midwestern cornfield perhaps. Not to mention 6GHz fades after about 5-6 miles. It’s therefore stripped the whole 6GHz band down to one 20MHz channel available.
