Abstract :
The implications of Shannon´s information theory for personal communication network (PCN) design are outlined. Examples of improvements in satellite communication, magnetic recording, and modem technologies that have increasingly approached information-theoretic limits are given. The emphasis is on the application of Shannon´s work to control of four types of interference: multi-user, multiple cell, multipath, and multiple media. Code-division multiple access (CDMA), time-division multiple access (TDMA), and frequency-division multiple access (FDMA) techniques in personal communications are compared.<>
