Hi There,
 
Did anyone else noticed the frame results changed from version 5.0.2.1 to version 5.1.1 ?   I use to be able to synchronize my PMP100 FSK frames with my PMP450 OFM radios using firmware 13.4.1 for the PMP100 FSK radios and my PMP450 OFDM radios operating on firmware 5.0.2.1.
 
But I'm not even getting close now after updating my PMP450s to version 5.1.1.  I've added some results below . I've tried for a few hours but altimately gave up since I'm pretty sure it's impossible to match the AP Receive starts between the two platforms now...The differance is just to great.  
 
Some advice would be greatly appreciated. 
 
FSK : 13.4.1
Range 12miles
Freq: 5.7Ghz
Downlink: 68%
Contention slots: 6
AP Antenna Transmit End : 14584, 1.458437 ms 
AP Antenna Receive Start : 15891, 1.589187 ms 
 
OFDM : 15.0.2.1
Range: 8miles
Downlink data : 72%
Contention slots: 8
 
AP Antenna Transmit End : 14497, 1.449770 ms 
AP Antenna Receive Start : 15982, 1.598230 ms 
 
Differance:  5.7Ghz FSK(13.4.1) vs 5.7Ghz OFDM (15.0.2.1)
AP Antenna Transmit End : 87 : perfect
AP Antenna Receive Start : -91 : perfect 
 
And here's the results for PMP450 running 5.1.1.  Unless I'm missing something fundamental I'm not sure it's possible to even co-locate the PMP100's with the PMP450's anymore ?  This is a rather big change!
 
OFDM : 15.1.1
Range: 8miles
Downlink data : 72%
Contention slots: 8
 
AP Antenna Transmit End : 14497, 1.449733 ms 
AP Antenna Receive Start : 16677, 1.667723 ms 
Differance: 
 
Differance:  5.7Ghz FSK(13.4.1) vs 5.7Ghz OFDM (15.1.1)
 
AP Antenna Transmit End : 87 : Perfect
AP Antenna Receive Start : -786  : WAY off mark.

No one else experiencing the same issue ?

Steph - We are looking into this... there was some slight changes, but these numbers aren't quite making sense.  We're digging in, and will post a response as soon as possible.  Thanks for your patience.

Cool beans .. I left the PMP450 using the 5.7Ghz band on 5.0.2.1 for now . Let me know if you need more info.

In order to co-locate a PMP 450 system with a PMP 100 system, you do not need to match the downlink and uplink times exactly. The turnaround time between the downlink and the uplink allows for some flexibility.

In order to check if your two systems can be co-located, you can use the PMP 450 - PMP 100 co-location tool, available on the Cambium support site: https://support.cambiumnetworks.com/files/colocationtool/
