Wireless Personal Communications Abstract| Cellular Digital Packet Data (CDPD) utilizes sleep mode mechanism to conserve the power of mobile end systems (MESs). A timer called T203 determines how quick an M-ES enters the sleep mode, and another timer called T204 determines how often the M-ES wakes up. A large T204 value and a small T203 value can eeectively(More)
ellular digital packet data (CDPD) [1–3] networks provide wireless data communications services to mobile users by sharing the radio equipment and unused RF channels with Advanced Mobile Phone System (AMPS) networks [6]. Basically, CDPD transmits packet data over idle AMPS channels, and autonomously switches to another channel when the current channel is(More)
— Cellular digital packet data (CDPD) utilizes sleep mode mechanism to conserve the power of mobile end systems (M-ES's). A timer called T203 determines how quick an M-ES enters the sleep mode, and another timer called T204 determines how often the M-ES wakes up. A large T204 value and a small T203 value can effectively reduce the power consumption at the(More)
