PCTEL Inc. is offering a new multi-band LTE/Wi-Fi/GNSS antenna with a sub-inch profile. The antenna combines PCTEL’s high rejection multi-GNSS technology for precision timing and location tracking with high performance multi-band data connectivity. The antenna is also rugged and easy to install, making it suitable for covert public safety operations, precision agriculture and the industrial Internet of Things (IoT). “Complex, high performance antennas are critical for modern public safety communications, as well as for commercial applications such as mobile asset management,” said Rishi Bharadwaj, senior vice president and general manager of PCTEL’s Connected Solutions group. “However, vehicles and autonomous systems have limited space for antenna installation. PCTEL’s sub-inch antenna addresses these space limitations while delivering high performance multi-band coverage. PCTEL also offers external and embedded antenna system design services for customers with more severe antenna size constraints or other specialized requirements.” Within its ruggedized ultra-low profile housing, PCTEL’s new antenna supports multi-band LTE MIMO and dual-band 2.4/5 GHz Wi-Fi for data connectivity, as well as GPS, GLONASS, BeiDou and Galileo GNSS satellite technologies. All GNSS elements feature PCTEL’s proprietary high rejection technology to ensure reliable satellite connectivity in the presence of LTE signals or other interference. The antenna has been fully tested for use in extreme environments and on heavy agricultural equipment. PCTEL will display its new multi-band LTE/Wi-Fi/GNSS antenna along with other antenna solutions for public safety communications at APCO 2017 in Denver Aug. 14-15, in booth #1943. The antenna can be ordered using part number GNSMB-COV beginning Aug. 15.
