radeng, I don't know if your radio engineering covers mobile phones but, if so, can you (or any other visiting expert) tell me what will happen when we have on-board pico-cells and the cell suffers a breakdown?
AFAIK there's no mechanism to disable the automatic function whereby all the mobiles on board will systematically boost their signal in an effort to contact another base station (35000 feet below). What is that likely to do to the instruments?!
