Abstract :
This paper presents a wireless sensor network (WSN) designed to assist in the characterization of radio propagation within buildings. The WSN comprises a number of 2.4GHz Zigbee nodes which measure RF power within the building and transmit these values to a central controller to record the values. Tunable band-pass filters (BPF) are used to select the frequency at which the RF signals are measured. In this paper two systems are presented, one for measuring signal strength within the Trans-European Trunked Radio (TETRA) band (380M-420MHz), the other within the AMPS and GSM 900 bands (806MHz-960MHz). Received Signal Strength Indicator (RSSI) of the 2.4GHz Zigbee signal are also sampled and recorded.
