Facebook has selected Tallysman’s TW2643POC GPS/Iridium antenna for the Facebook Open Cellular Platform. Facebook’s Open Cellular group is developing a cost-effective, software-defined, wireless-access platform to improve connectivity in remote areas of the world, the company said. The TW2643POC employs Tallysman’s Accutenna technology in a magnet mount, passive right-hand circularly polarized antenna for the reception of all of the GNSS constellations (GPS L1/GLONASS G1/ Galileo E1/ BeiDou B1) plus Iridum: 1559 to 1626.5 MHz frequency band. According to Tallysman, it is certified and specially designed to maximize the performance of Iridium Voice and Data Modems plus the upper GNSS band (1559–1606 MHz). The TW2643POC is housed in an IP67 compliant housing and is REACH and RoHS compliant.
