Tactical Airborne Adhoc Radios Base Station
Fast Deployment, Create Network in Seconds
●In emergency situations, every second counts. The U25 repeater supports push-to-start for quickly and automatically establishing an independent network after power-on so as to efficiently extend radio coverage.
Infrastructureless Network: Free of Any IP link, Flexible Topology Networking
●The repeater adopts wireless interconnection technology to quickly create multi-hop narrowband networks through cascading connection, free of any IP link such as fiber optic and microwave.
Extends Networks Beyond-Line-Of-Sight
●When UAV taking U25 hovers in the air with 100 meters vertical height, the communication network can cover 15-25km range.
Airborne Integrations
●Defensor-U25 is an integrated base station designed for mounting on UAVs.
●It's suspended by four hanging fopes, compact in size, and lightweight.
●Equipped with a specialized 3dBi directional antenna and a internal lithium battery(10hours battery life).
●Delivers extensive coverage with a broad 160-degree angle directional antenna for over 6-8hours continuous working.
Single Frequency Supports 1-3Channels
●Multiple units U25 or several units U25 and other types base stations of the Defensor family create a multi-hop narrowband MESH network.
●2 hops 3-channel ad-hoc network
●6 hops 1 channel ad-hoc network
●3 hops 2 channels ad-hoc network
Cross Platform Connectivity
● U25 is a SWaP-optimized solution leverage the field-proven, hardware platform of the Defensor family of handheld, solar powered base station, vehicular radio station and on-site portable command system to extend the emergency voice communication connectivity to the air.
Remote Monitoring, Keep Networking Status Always Known
●The ad-hoc network created by the Defensor-U25 repeaters can be monitored by the portable on-site command and dispatch center Defensor-T9. The online of offline status, battery level and signal strength.
●when public network is down, IWAVE narrowband MESH system quickly establish a reliable communication network to ensure stable connectivity for emergency rescue, public safety, major events, emergency response, field operation, and more.
●It provides on-the-move communications for dynamic network adaption which easily supports ground platform speeds and airborne platform speeds to better support users who are spread out in highly mobile ground formations.
