I am replacing a PTP230 link with the new PTP450.
PTP230:
Reflectors: Cambium metal reflectors
Distance: 8 miles
RSSI: -63dBm
SNR: 30dBm
Link Capacity: 100% 40Mbps down, 10Mbps up
Sync: Power port via CMM3
firmware: 11.2
When I replace the PTP230 radios with the PTP450 radios:
Distance: 8 miles
RSSI: -66dBm
SNR: 30dBm
Link Capacity: 100% 75Mbps down, 15Mbps up
Sync: Syncpipe (PTP450 doe not support power port timing, which is a real kick in the nuts, but digress)
firmware: 13.2
All looks good right? Wrong. When I put the PTP450 link under load the link disconnects. From the master side, the "Reg" stats for the slave count up each time there is a disconnect. The disconnects are worse when the traffic demand is higher. If I remove all traffic from the link, the connection appears to stabalize.
Troubleshooting:
The PTP230 works perfectly with the same traffic loads.
Spectrum scans show that the channel used (5820Mhz) has a flat noise floor below -100dBm.
Trying different Frequencies provides no improvement (5480Mhz, 5820Mhz, 5840Mhz)
Using a uGPS provides no improvement
Replacing the master provides no improvement
Replaceing the slave provides no improvement
Replacing the cat5 cable provides no improvement
In conclusion, the prodect does not work. I have replaced everything and tried everything. The PTP450 link simply cannot bridge high traffic withou disconnecting.
