Abstract

Firstly, the technical features and frequency characteristics of IEEE802.11x protocol in wireless local area network (WLAN) are introduced. The uplink and downlink radio power budget of current WLAN outdoor coverage is given. The functional relationship of path loss and coverage distance in dense urban is shown in figures. Secondly, hot spot area WLAN outdoor coverage signal strength simulation has been done in dense urban for several situations by using simulation software. The results of simulation validate the accuracy of the calculation for uplink/downlink power budget and path loss in WLAN 2.4GHz band. Finally, a valuable hot spot area WLAN outdoor coverage deployment suggestion is given: high power WLAN BTS/AP and high gain antenna with 4 sectors deployment will improve the uplink/downlink power budget and enlarge radio coverage in hot spot area. The analysis in this paper is significant for the deployment of wireless digital city.
