Overview
The Helix Mesh Rider Radio is an advanced MANET data-link. Six frequency bands (M1-M6) in the 1625 to 2500 MHz range allows it to be used globally.
Helix 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, optimized video streaming carries crystal clear 4K video while simultaneously carrying low latency command and control data.
The interoperable Mesh Rider Radio platform is available in many frequency bands between 600 MHz and 6 GHz in Nano, Mini, OEM, Embedded, Wearable and External form factors. This flexibility allows customers to use their industry specific frequency bands for deploying private wireless networks that encompass all the use cases for human and machine collaboration.
