WiFi Hotspot for Private Wireless Networks

Military and Defense operations need reliable, high-quality communications to carry out defense missions in a variety of environments, and they can take advantage of less crowded frequency bands for optimal performance. The 2.2 GHz Smart Radio from Doodle Labs delivers for these needs by establishing a private MANET on the Federal S-Band. The S-Band ranges from 2200 to 2300 MHz and has a very long range, and similar benefits to the 2.4 GHz WiFi Band without the noise from other connected devices, making it ideal for urban environments.

Typical uses for our S-Band broadband radios in Defense applications include:

  • Swarming with Unmanned Aerial Vehicles (UAVs) / drones on a mesh network
  • Communications infrastructure for various unmanned/autonomous ground vehicles, with airborne mobile systems, and personnel
  • Control of robotic systems for explosive ordnance neutralization and disposal
  • Military research
  • Air combat training systems
  • Law enforcement video surveillance
