HI,
I have an indoor mobile phone network in the 2100 band, (Band 1) and we are seeing extensive interference affecting the UL mobile signals and generating base station noise. (1920-1980 but centered around 1960). I have received similar reports from Australian hospitals and the common element appears to be the closeness of imaging equipment to the antennas. in my case floor below. Any members with similar experience or aware of the mechanisms?
