摘要
This paper will discuss the issues of providing multiple data rates (1/2/5.5/11Mbps) over an IEEE 802.11 infrastructure wireless network. With the characteristic of modulation schemes, the data rate of wireless network is inversely proportional with the transmission distance. A moving mobile station needs dynamically adjust the modulation scheme to keep connection alive and to achieve the maximum network throughput. To do this, mobile stations are requested to detect the distance between access point and itself from time to time. In this paper, a simple broadcasting approach will be proposed for mobile stations to detect their locations in wireless network. Based on this information, mobile node can easily determine the proper transmission rate.
