摘要:
A method for WLAN signal strength determination comprises receiving a WLAN RF signal; converting the WLAN RF signal to a voltage proportional to the signal; comparing the voltage to a first reference voltage; and outputting data corresponding to WLAN RF signal strength if the voltage is greater than the first reference voltage.
