WLAN

A Wireless Local Area Network (WLAN) is a flexible data communication system in which a mobile user can

connect to a local area network through a wireless connection. The standard, which specifies the technologies

for WLAN, is called IEEE 802.11. The device supports both IEEE 802.11b and 802.11g standards, so the

supported data rates are from 1 Mbps to 54 Mbps in 2.4 GHz ISM band.

WLAN ASIC is powered by VBAT. VIO is required for SPI which connects WLAN ASIC to host processor. WLAN

requires 38.4 MHz reference clock which is taken from RF VCTCXO via BT/WLAN clock buffer. WLAN shares the

same antenna with BT and common RF path is shared according to the coexistence signaling between the

ASICs.
