Sonim Technologies™ partnered with goTenna to enhance optimal reliability and connectivity for the Sonim XP8 ultra-rugged smartphone in off-network situations. goTenna's innovative mesh networking protocol is embedded into lightweight, low-cost tactical-grade radio devices and paired with easy-to-use mobile devices and applications enabling mobile, long-range connectivity even without cell, WIFI, or satellite. As more and more first responders and industrial workers use mobile devices in the field, the need to stay connected — especially in demanding and sometimes comms-denied environments — becomes even more critical. Both of goTenna's professional radio device models — goTenna Pro and goTenna Pro X — pair with the Sonim XP8 Android smartphone via Bluetooth LE or USB tether. The Pro X device model specifically offers compatibility with third-party apps, such as the Team Awareness Kit for Android (ATAK or CivTAK) for real-time situational awareness and collaboration. The goTenna radio devices are available as standalone units and as a part of ruggedized Deployment Kits, which store, configure, and charge up to 30 units. Key features of a paired goTenna Pro radio device and Sonim's XP8 handset include: Durable: Sonim's high power 4900mAh battery charges Pro or Pro X devices paired to the handset via USB tether for multiple shifts. Programmable: goTenna's software development kit (SDK) supports custom and third-party applications for low-bandwidth data transmissions. Readily Available: The solution is available via leading Sonim resellers in the U.S. and Canada, and goTenna resellers in over 75 countries. goTenna Pro and Pro X devices meet Sonim's ultra-rugged, IP-68 performance standards, and contain Intrinsically Safe Class I and II, Division 2 Class III, Divisions 1 and 2 certifications. It is a dual band with up to 5W VHF/UHF output and enables mesh networking with a six hop limit per unit. Like Sonim XP8 handsets, goTenna Pro and Pro X devices meet the demands of austere operating environments.
