For over fifteen years Phase IV has been engaged in research, development and production of wireless sensing and monitoring products. Wireless sensing is an evolution of telemetry and is closely related to RFID (Radio Frequency Identification). In effect, it provides the communications and identification capabilities of RFID with sensing and monitoring included. To these Passive RFID and Active RFID sensing systems, Phase IV has added GPS, local area network and SATCOM communication links for world-wide, infrastructure-free tracking and monitoring. These systems were developed for aerospace and military applications and have now been optimized for commercial applications. Our innovative technologies offer platforms that enable our customers to find creative solutions to business problems and develop breakthrough ideas.
