Abstract:
A method of obtaining, for base station deployment purposes, a determination of whether a wireless handset at a location is inside or outside a cell boundary of a base station, said method comprising the steps of:(a) the wireless handset transmitting a test signal from the location, said signal carrying a transmitted test sequence of bits;(b) the base station receiving from the wireless handset a received signal carrying a received sequence of bits;(c) the base station measuring a received signal strength intensity (RSSI) level for the received signal;(d) the base station measuring a high resolution bit error rate (BER) level for the received sequence, with reference to the transmitted test sequence;(e) the base station making the determination that the handset is outside the cell boundary if the measured RSSI-level is less than an RSSI threshold;(f) the base station making the determination that the handset is outside the cell boundary if the BER-level exceeds a BER threshold; and(g) the base station indicating the determination.
