900 MHz Smart Radio

The Smart Radio is the most advanced MIMO mesh router.

Space and Weight constrained Systems


Vehicle Mounted Installations, IP67

WiFi Hotspot for Private Wireless Networks

The 900 MHz ISM Band is license-free in many parts of the world, including USA, Canada, Australia, New Zealand and 23 countries in the Americas. The 900 MHz band can be used for any commercial IoT application, making it a viable alternative to the more crowded 2.4 GHz band. On this frequency, our Smart Radio can provide an ideal solution for:

  • Industrial, Logistics, Warehouse Equipment and Unmanned Systems
  • Long Range data links for Unmanned Aerial Vehicles (UAVs) / drones operating in remote and challenging environments
  • Mesh communications for Unmanned Ground Vehicles (UGVs) and Robots in extreme environments like tunnels and mines
