Overview
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.

Band Introduction – 900 MHz ISM Band
The 1370 MHz band ranges from 1350~1390 MHz. This band's transmission characteristics make it desirable to achieve a good balance of range and penetration for mobile ground-based robots. The RF signals at 1370 MHz have the ability to propagate further distances via two mechanisms: penetration and diffraction. Penetration refers to 1370 MHz waves ability to penetrate through building walls, vegetation and other obstacles. 1370 MHz waves can go through multiple building walls making it an excellent choice for applications that do not have a direct line of sight between sender and receiver. Diffraction describes the characteristic of a 1370 MHz wave that it can go around an object such as a building or vegetation. 1370 MHz waves have smaller Fresnel zone.
The DoD operates telemetry systems in this band that are used to transmit and receive data from airborne vehicles at test and training ranges. Additionally, the DoD operates transportable tactical point-to point communication systems in the 1370 MHz band. These tactical communication systems are used for command and control networks for military ground forces. This is the only transmission media available to the Marine Corps with sufficient bandwidth to carry large quantities of critical data such as maps, overlays, intelligence pictures, and other data to the battlefield commanders. These systems are used within the United States for comprehensive and realistic training to maintain a high level of combat readiness. The DoD will continue to operate tactical transportable fixed point-to-point communication systems in this band for the foreseeable future.
System Integration
