The Sprint phone is normally alright - but it does drop calls. Also the signal strength display on the PCS phone changes just by moving or changing the orientation of the phone (e.g. from 5 bars to 1 bar or vice/versa). Any CDMA/GSM/TDMA experts out there who can explain this (and are not long QCOM/PCS ?) Sprint uses a higher frequency for communication. This has higher loss and as you have found, very small distances from peak to minimum power. At the beginning of a cellular system it is best to have low frequencies so a single tower covers a large area. As the system becomes heavily loaded and cells are split, it is better to have high frequencies that attenuate rapidly with distance. This allows more cells to be packed in. Sprint uses about 1900 MHz (or 1.9 GHz) and AT&T uses around 900 MHz. Sprint may have an advantage when microcells are used in the ultimate quantity of communication available.
