Datasheet: Wearable Mesh Rider Radio – 2400~2480 MHz (WiFi Band)



The Wearable Mesh Rider Radio brings private wireless networking and dynamic mesh capabilities to connected workers. Each device is a node on a long-range Mesh Rider network and uses WiFi to bridge Tablets and Smartphones onto the network. The Wearable Mesh Rider Radio is used by tactical teams to collaborate by streaming voice, video, and data on a fast, low latency, and encrypted network.

13The Wearable Mesh Rider Radio was designed to be conveniently carried. Embedded antennas are capable of streaming HD video to a teammate up to 1 km away. External antenna ports are included to integrate with high-gain antennas for longer distances. The radio can be powered by a variety of sources, including tablets and standards-based battery banks. It is also available in an OEM form factor for embedded use cases.

As with all Mesh Rider Radio form factors, the Wearable is available in many frequency bands between 900 MHz and 6 GHz freq range. This flexibility allows customers to use their industry specific frequency bands for deploying private wireless networks.

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, optimized video streaming carries crystal clear 4K video while simultaneously carrying Ultra Reliable Low Latency (URLLC) command and control (C&C) data for machines.
