Introduce the application of the Wireless LAN technology in the embedded system platform based ARM9, discussed the roaming switch problem that the mobile terminal exists in the wireless network environment , as well as the current AP automatic se-lection. Proposed the communication situation between the MH and AP by using the soft-threshold function, and then realize the adaptive access mechanism solutions for the embedded mobile terminal under the central control of Wireless LAN mode.
