A Wireless Infrastructure to Support Research Activities Outside the wireless LAN service area, we are using the cellular digital packet data (CDPD) service offered by Bell Atlantic Mobile. With both the CDPD and wireless LAN networks operational, properly equipped mobile computers will be able to use both networks.作者: 創(chuàng)造性 時間: 2025-3-22 01:16

Minimization of Outage Probability in Cellular Communication Systems by Antenna Beam Tilting important especially for interference limited cells. For an antenna height in excess of 50m, missing the optimum tilt angle by 1° leads to an increase in the outage probability by a factor of up to seven.作者: peptic-ulcer 時間: 2025-3-22 08:42
On the Performance of 4-Phase Sequences in Asynchronous CDMA Systemsymptotically approach lower bounds on maximum cross-correlation. While a probabilistic analysis indicates that the performance of both types of sequences is equal, a deterministic analysis shows that 4-phase sequences indeed offer better average probability of error performance than 2-phase sequences for cases analyzed thus far.作者: 催眠藥 時間: 2025-3-22 12:54 作者: inconceivable 時間: 2025-3-22 18:30
