Embedded/External Mesh Rider® Radio – 2200~2300 MHz

Overview

Alt

The Mesh Rider® Radio is an advanced 2×2 MIMO mesh router designed for easy plug & play integration. The tiny module carries all bi-directional communication (e.g. Telemetry, Video) in a single high-speed broadband RF channel.

Due to its very low SWaP-C (Space, Weight and Power and Cost), the Mesh Rider® Radio is very popular for mobile IIoT (Industrial Internet of Things) applications like drones, autonomous vehicles, and mobile robotics applications across various industries.

The Mesh Rider® Radio employs Doodle Labs' patented Mesh Rider® technology with state-of-the-art RF and networking capabilities that enable communication further, faster, and more reliably than any comparable solution on the market. For example, the Ultra Reliable Low Latency Channel (URLLC) transports important command and control data over the wireless link, while a concurrent video-optimized streaming channel carries crystal clear 4K video.

The Mesh Rider® Radio is available in many frequency bands between 100 MHz and 6 GHz in form-factor compatible models. This allows customers to switch the operating band by simply swapping the radio module, avoiding costly re-design efforts when expanding to new markets that require new frequencies. The Mesh Rider® Radio is available in embedded and external form factors.

    The 2250 MHz band ranges from 2200~2300 MHz. It is used exclusively by the Federal Government. Typical uses include military research, law enforcement video surveillance, control of robotic systems for explosive ordnance neutralization and disposal, testing of robotic ground vehicles and airborne mobile systems for air-to-ground video telemetry, air combat training systems, and unmanned aerial vehicles.

    System Integration

    The Mesh Rider® Radio is an embedded module. It has been designed to be nearly plug and play. Only Ethernet, power supply (5.5~42V), and antenna connections are required for integration.
