| Abstract(in English) | There are Access Point (AP) selective problems to which AP a new terminal should access. It is important to select APs corresponding to proper transmission rate. As for wireless LAN, the proper transmission rate can be selected in proportion to bit error. Though computer simulations have investigated the relationship between throughput and the distance from a terminal to an AP, real machine experiments have not evaluated the relationship. This paper measured throughput relative to the distance on each rate outdoors. The experimentally measured throughput was more sensitive than the simulation results and monotonically decreased as the distance from an AP increased. We consider two reasons for this mechanism: One is an increasing frame retransmission rate in the MAC layer, and the other is an increased frame transmission waiting time, as the carrier is considered noise. We have clarified the intimate relationship among throughput, the MAC frame retransmission rate, and the carrier busy state in poor radio conditions. This paper quantitatively investigates these two factors that reduce throughput. |
