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.
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, many billions of dollars have been invested into developing IEEE 802.11 (WiFi) technology. Today the WiFi ecosystem is estimated to exceed two trillion dollars. As a result of such massive investments and pervasive use, 802.11 is 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 802.11 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 to achieve interference-resistant, high speed wireless communication. As reliability is critical in most industrial applications, Mesh Rider takes advantage of IEEE 802.11 built-in capabilities such as MIMO, multi-path advantage, FEC, and STBC.
Self-forming and self-healing, multi-hop relay, multi-frequency mesh capabilities improve the network robustness, extend the range.
Advanced traffic prioritization of Ultra Reliable Low Latency Channel (URLLC) for all Command and Control traffic and concurrent multicast video streaming of 4k video on the same link.
Spectrum Scan monitors in-band interference and provides the capability to switch channels. The advanced filtration and frequency-band shifting techniques are designed to minimize noise and block out-of-band signals.
The hybrid SDR technology 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.
Encryption is a vital requirement to protect the data from the snoopers. The Mesh Rider’s built-in 256-bit AES encryption protects over the air traffic. The embedded encryption engine is compliant with Federal NIST standards: FIPS 140-2 Level 2 and NSA Suite B.
The Mesh Rider is built on top of a feature rich OpenWrt Linux OS. Users can install their own software to further extend and customize the functionality.
A cornerstone of Mesh Rider is the advanced networking capabilities closely integrated with the RF waveform. The Mesh Rider has been developed to enable a large variety of Private Wireless mobile use cases as depicted in this gallery.
The Mesh Rider 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. These automatic multiple pathways builds network redundancy. As the number of nodes increases, the network becomes more resilient by having more alternate pathways and eliminates any single point of failure.
A cornerstone of Mesh Rider is 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 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 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, it can rapidly update when a node joins or leaves the network. Mesh Rider emulats a virtual network switch of all nodes participating. Therefore all nodes appear to be link local.
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.
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.
Another powerful feature of Mesh Rider waveform 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 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 low latency, high speed private wireless solutions for many industry verticals and their associated special bands.
