But, if you read between the lines, or at least my read on it is... The wireless telcos agreed to pay the Incumbent Earth station operators to vacate the spectrum, the Airlines are a little cash strapped after the pandemic lock down, so, they figured why not stick our hand out and see if we can get a little cash out of the telcos. Just my take on it, but reading the RTCA doc, the whole thing is completely baseless. But, having said that, here is something to consider, the primary concern raised by the RTCA is not so much the base stations themselves, which are far away and hence, not an interference source, it is the phones on the plane as it lands, which are much closer to the radar antenna which is in the ass end of the plane (the lowest point on take off and landing). If a phone is on in the plane it will drag the call along, if you turn down the BTS's around the airport this compounds the problem because the dynamic power control of the phone will power up in an attempt to hold the connection. In Europe, they have been using this same spectrum for a long time with no problems, so in the U.S. we are doing the opposite and turning down BTS's near airports. So do the opposite of what works elsewhere in response that actually aggravates the exact problem being raised. In other words, the best thing is to leave BTS's up near the airport so the phones, closer to the radar antenna, will not interfere, like what works in Europe, so the phones don't increase power. So, we are doing the opposite.
