Can anyone confirm they have actually been able to enable a 5850-5895 frequency in the scan list on a 450b6 SM? Not asking if it SHOULD work, but have you seen it actually work?
I think we’ve tried every FW that can be loaded on a 450b6 including 24.0.1 STA, 24.1.1, 24.2.1, and even 24.2.1 SIT-2 from the STA repository. In each case, the 5.9 freqs are greyed out in the Radio tab, and there is nothing under Region Settings in the General tab to enable the 5.9 sub band.
If someone else has been able to check the boxes in the scan list, I will assume we’re doing something stupid and keep working on it. But is it possible this is a FW bug? If 5.9 isn’t supposed to work on a 450b6, the checkboxes should be absent, not greyed out.
At the bottom of the general status page, do you see the “FCC Special Temporary Authority UNII-3 Band Extension 5850 - 5895 MHz” set to “True”?
Nope, not there. I did get info back from Cambium Support they are looking to put this capability for the 450b6 into the next firmware release.
I just accidentally discovered this problem doesn’t occur until you set the Region to North America / US.
Yeah, that’s because the feature key to unlock the 5.9-STA band extension for the NA/US region isn’t installed.
Once it connects to the AP, it adopts the region code of the AP, and those frequencies get greyed out. But normally loading STA firmware will set the feature key. In the case of a 450b6 there doesn’t seem to be any compatible FW that will do that.
Hi Ken -
This was an oversight on the 450b6 device not allowing these frequency options. It will be available in the 24.2.2 beta which should be coming soon.
Looks like they’ve resolved this issue in 24.2.2 beta.
CPY-19670: PMP 450b6 SM doesn’t allow the selection of STA channels 5850 – 5896 MHz
