Well just about the time I understood Cell Operation, I learn some thing new. At one time Cell mobiles were only allowed to have an antenna with max 3db gain even though there were 5 db antennas on the market. Also, mobiles ran 3 watts while hand helds were 600 mw. I never could understand why 25 and 50 watt base stations were used. I realize that duplexers and multi couplers have high loss at 800+ but that still does not account for the difference. In the digital world, what is the usual power level difference between hand helds and the bases?
