What Every Radio System Must Consider

Radio systems, like life, demand tradeoffs or compromises. The CDG says, "CDMA cell coverage is dependent upon the way the system is designed. In fact, three primary system characteristics-Coverage, Quality, and Capacity-must be balanced off of each other to arrive at the desired level of system performance." Wider coverage, normally a good thing, means using higher powered mobiles which means more radio interference. Increasing capacity means putting more calls into the same amount of spectrum which means calls may be blocked and voice quality will decrease. That's because you must compress those calls to fit the spectrum allowed. So many things must be balanced. As the saying goes, radio systems aren't just sold, they are engineered.
