Abstract
An improved radio deployment tool (RDT) for determining cell boundaries is disclosed. An RDT used to carry-out active deployment procedures consists of an RDT wireless handset (RDTWH) that a deployment engineer uses to generate test signals, and an RDT base station (RDTBS) that is used to measure the RSSI of the test signals sent by the RDTWH. The RDTBS factors in the impact of short-term fades and dispersion, as well as long-term fading, by measuring and processing bit error rate (BER) and received signal strength intensity (RSSI) levels. BER levels can be measured for signals whose RSSI-levels have been driven into a testing range at which signals are susceptible to short-term fades and dispersion. A sufficient resolution of BER measurements is achieved by filling the payload fields of test packets exchanged by the RDTWH and RDTBS, with BER test data. The payload fields of the test packets can be filled by pressing down the mute button of the RDTWH.
