Do we know if the HAAT rule applies to low power consumer devices that are able to use the 1st adjacent channels? See my other posts about using separate transmit and receive architecture in TVWS radios. You could place these receivers at various locations which work for the propagation characteristics of the channels to be used. Add high gain antennas to the receive site to better enable them to hear the low power devices. The receiver site does not have HAAT limits if it does not transmit. If the consumer devices do not have HAAT limits and you can locate a high power transmitter in a location that meets the HAAT requirements for the downlink your problem may be solved.

However, I am in an area where large chunks are well above the TVWS 75m limit, but other locations less than a quarter mile away are well below it. I would like to see what the possibility is of swapping most of my 900 customer base to TVWS. I am wondering how many of them will be above the limit...
