The Research Of Access Point (AP) Based On 802.11b WLAN

Wireless Local Area Networks (WLAN) based on IEEE802.1 lb is a new and booming branch in data communication, which has a promising future. Among the WLAN networks, the Access Point (AP) is the most important device, and its performance would affect the range and the throughput of the network greatly. Therefore, the research on this device is of great significance for WLAN system.This dissertation describes the general architecture of hardware and software system, and the functions and the processes of each software module are presented in general. After that the paper describes the low level driver module in details, including the interfaces with up level and hardware, some important structures and sub-modules, etc.This software was designed on the basis of the embedded real time operation system (RTOS) VxWorks, under the integrated developing environment (IDE) Tornado II, and it kept to the developing process for embedded software, which can be consulted for the development of real time data transmission software.After the release of the first edition, the device was strictly tested and evaluated, which manifested the good performance of the device. It has been put into application now and the reaction is not bad.
