Nano OEM - thumbnail edited

The RM-2100-41N Mesh Rider Radio is an advanced MANET data-link. The 1370 MHz and 2200-2510 MHz bands are supported allowing it to be used in various federal applications.

The RM-2100-41N 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.
