Performance Evaluation of Wireless WIT2410 Radio Frequency Transceiver used in AMIGO (Autonomous Microsystems for Ground Observation)

摘要

The objective of project AMIGO (Autonomous MIcrosystems for Ground Observation) is to develop a proof-of-concept, low cost, compact unattended ground sensor suite that can provide real time situational awareness for the CF from remote locations. Two of the major components in AMIGO are the RF transceiver and antennas for wireless communication that must provide reliable connectivity between the base station and each remote unit in any battlefield conditions. The transmission scheme should also be low probability of detection and interception (LPD/LPI). After a vigorous selection process, the RF transceiver WIT2410 was chosen for this R AND D work. The WIT2410 (Wireless Industrial Transceiver) from Cirronet can provide wireless connectivity in point-to-point or multi-point applications. The frequency hopping spread spectrum technology of the WIT2410 ensures maximum noise resistance, multi-path fading immunity, robustness in presence of interfering signals, and LPD and LPI. In this work, different types of antenna and antenna configuration were tested with the transceivers at various locations at DRDC Valcartier. The RF signal strengths were recorded and compared. With this information, one can determine the WIT2410 limitation, reliability, and achievable range in different settings.
