Mesh Rider® is an innovative, patented mobile mesh wireless broadband technology developed by Doodle Labs. It focuses on high-throughput data communication over long distances (up to 100 km) and provides frequency flexibility, enabling operation in licensed and license-free bands.
Mesh Rider extends the state-of-the-art COFDM/MIMO technology used by the IEEE 802.11 standard and optimizes it to meet the challenges of Industrial IoT and Defense applications. Doodle Labs Smart Radios, built with Mesh Rider technology, are carrier grade and deployed in some of the most demanding environments in the world by Fortune 100 companies.
The unique mix of capabilities and features makes Mesh Rider particularly relevant for deploying Industry-grade private network for mobile robotics applications, such as drones and unmanned ground vehicles.

Shield from cyber threats with a private network so that the sensitive data never leaves the premises. The Mesh Rider incorporates advanced 128/256-bit FIPS compliant AES encryption for the highest levels of data security.
The SDR technology of Mesh Rider enables a large family of form factor compatible models in 100 MHz to 6 GHz frequency bands. Simply swap out the radio based on the end-customer or country requirements.
As the world becomes further connected and new applications arise, a diverse set of requirements emerge for wireless connectivity. Many technologies and standards have been developed to fill the needs of different applications and their corresponding requirements (e.g. range, power, speed). No single technology can meet the needs of all use cases.
The chart illustrates the sweet spot for Mesh Rider relative to other technologies. Indeed, it is capable of deploying high performance private mobile broadband networks that require long-range and high-throughput capabilities, like UAVs, and UGVs.
Mesh Rider has been designed to combine the benefits of cellular LTE and WiFi technologies. Public cellular LTE networks used to be the only possibility for medium to long range (100+ meters) applications. However, because they have been designed to serve many users, cellular networks provide low user speed, low QoS, and high latency to each individual subscriber. Moreover, their high monthly recurring costs lead to high total costs of ownership.
Mesh Rider addresses these pain points by building on top of the robust COFDM/MIMO technology specified in IEEE 802.11. High throughput, low network latency, and high QoS are extended to long distances.
Over the past two decades, billions of dollars have been invested into developing and deploying WiFi-enabled systems. Today the WiFi ecosystem is estimated to exceed two trillion dollars. As a result, WiFi has become the most advanced and high-performance wireless protocol.
Doodle Labs has been a major player in long-range WiFi for over 20 years. Based on this expertise, Mesh Rider begins with WiFi as a foundation and adapts/extends it for more demanding Defense and Industrial IoT applications.The Mesh Rider waveform optimizes numerous physical and MAC layer parameters (e.g. frame timing matrix) to achieve interference-resistant, robust, wireless broadband communication. As reliability is critical in most industrial applications, Mesh Rider takes advantage of capabilities such as MIMO, multi-path, FEC, ACK-retransmits, and STBC.
A cornerstone of Mesh Rider are its advanced mesh capabilities, which have been developed with mobile use cases in mind. It operates on ISO/OSI Layer 2 and routes/bridges ethernet frames. It emulates a virtual network switch of all participating nodes making it possible to run almost any protocol on the mesh.
The mobile mesh helps deploy self-forming, self-healing mobile ad-hoc networks (MANET) by employing any-node to any-node capabilities to instantaneously route data via the best available traffic path.
Mesh Rider also builds redundancy in the network by utilizing multiple pathways for the traffic. As the number of nodes increases, the network becomes more resilient by having more alternate pathways and eliminates any single point of failure.
Because Mesh Rider operates on Layer 2 (instead of Layer 3 as some other mesh protocols), the network topology doesn’t need to be remapped every time a node joins or leaves the network. Mesh Rider encapsulates and forwards all traffic until it reaches the destination, hence emulating a virtual network switch of all nodes participating. Therefore all nodes appear to be link local and are unaware of the network’s topology as well as unaffected by any network changes.
It should be also noted that Doodle Labs is working on the development of the next generation mesh system that routes traffic while dynamically adjusting to all network topology/environment changes in real-time.
Remotely controlling mobile vehicles requires reliable and low latency command and control communications. Mesh Rider provides this capability in a special port-based URLLC (Ultra Reliable Low Latency Channel). Similarly, Mesh Rider includes optimized QoS channels to carry the ultra-definition video and voice traffic.
For highly secure applications, the Mesh Rider has built-in 256-bit AES encryption for over the air traffic. It is compliant with Federal NIST standards (e.g. FIPS 140-2 Level, NSA Type 2) and is used in variety of forward-deployed military applications.
The multi-hop relay capability extends the range further. By leveraging the Mesh Rider’s frequency flexibility (discussed later), it is possible to eliminate the loss of data throughput that typically accompanies every relay node. Multi-frequency also provides additional redundancy by continuously choosing the best frequency to transmit data to the desired destination.
Multicast allows a node to transmit data to a group of receivers, such as in the case of a drone transmitting a live video feed to multiple ground users. Mesh Rider includes capabilities that allow you to optimize multicast performance, including selecting specific listeners within a large mesh network.
Unlike many static waveforms in the market, Mesh Rider keeps up with the advances in the wireless technologies. Over the years, the Mesh Rider has evolved to take advantage of 802.11 a/b/g and finally the latest MIMO standards. In 2021, Doodle Labs will update its technology to leverage the exciting 802.11ax standard and advances like 1024 QAM, OFDMA, MU-MIMO, and Beam Forming.
In line with not re-inventing the wheel, one of the cornerstones of Mesh Rider is OpenWrt, a robust and well-established open source OS that powers a few hundred million routers today. It provides a rich library of over 2,000 apps, extensions and all the power of the Linux eco-system. As a result, Mesh Rider is incredibly developer-friendly, allowing integrators to rapidly build complex networking functionality into their systems.
Another powerful feature of Mesh Rider is Doodle Labs’ Prism technology. This technology allows Doodle Labs radios to take a carrier frequency and shift it to any desired frequency between 100 MHz – 6 GHz. The Mesh Rider waveform can operate in any frequency band, and the channel size can be software defined as required by the application’s throughput and range requirements.
The ability to define the channel size coupled with auto adjusting bit coding rates allows Mesh Rider to be spectrum efficient and operate at the maximum SNR possible. This capability allows Doodle Labs to provide private wireless broadband solutions for many industry verticals and their associated special bands.
Doodle Labs has packed the powerful Mesh Rider technology in 3 easy to use models. The Embedded model is one the smallest and lightest radio available in the market. The External model is thoughtfully designed for quick field deployment and requires only a screwdriver. The Pocketable (coming soon) is a lightweight and compact model (smaller than a smartphone) that provides a WiFi and Bluetooth hotspot in the field for regular tablets, smartphones and BT headphones, while using Mesh Rider for long range connectivity to the base.
