Daniel is correct, and the notion that one could coordinate and license an 80 MHz channel pair with a 40 MHz pair separated by 60 MHz to somehow block out a 120 MHz chunk to then operate a 112 MHz bandwidth ETSI configuration is patently false. Any vendor (integrator, radio OEM or coordinator)

Just confirming that this is actually two (2) dual core radios - one CCDP at 80 MHz bandwidth and the other CCDP at 40 MHz bandwidth with the two transmit frequencies separated by 60 MHz - correct? This will require couplers and associated losses on both ends (approximately 7 dB). Any attempt

It is primarily needed for adjacent channel or non-co-channel interference situations as there can be wide differences in filtering. But even for co-channel, its important to know the practical threshold as well as the required T/I value that allows no more than 1 dB of degradation due to

A note of caution: Some vendors have been pushing the notion that at 11 GHz, one can coordinate and license an 80 MHz bandwidth pair along with a 40 MHz bandwidth pair separated by 60 MHz to in effect get a contiguous 120 MHz of spectrum. This is okay as long as you are transmitting two

2+0 Co-Polarization will add couplers and losses on each end, and I believe that LinkPlanner automatically puts those in when you specify this. With the Aviat WTM, you would be using the WTM-42C (coupler version) which has the coupler losses baked-in to the specs. > On Jan 4, 2021, at 2:51

The dual-core WTM-4200 radio only suffers a coupler loss hit. I think you’re referencing the single-core WTM-4100 using Adaptive Dual Carrier (A2C) which has a significant power hit at 1024 QAM and above. > On Jan 4, 2021, at 3:01 PM, Mathew Howard wrote: > > Yeah, you can do 2 x 80mhz

I haven’t seen the PCN you reference, but I suspect it is a standard satellite ground station PCN since 18 GHz would be their downlink and 28 GHz the uplink. Part 25.203(c2) covers the coordination requirements for ground stations in shared bands and the PCN must include an antenna horizon gain
