I think the spurious emissions would be a big problem. You would be amazed at the levels of EMI emitted by phones when they are in certain modes. While looking at some dual & tri-mode digital phones from 3 different manufacturers (while placing digital calls in the 1800± MHz range?? or maybe the upper 800's range - I forget), I have seen emissions that were regularly 20-30+ dB above Class A from 40MHz all the way up to 1GHz (narrowband spurious, but distributed seemingly randomly all over the place).
These emissions were from the phone itself on a turntable - no cables, just the phone taped to a cardboard box. Anecdotally, think of your PC speakers - I know a lot of people who know that a TDMA call is coming in when their speakers click. I must admit I haven't looked, but maybe the mall stores sell sterile faceplates? :) Best Regards, Dave Heald John Shinn wrote: > If he had a LOW EMI Phone, how was he able to transmit out of the > OR?
