Best of WiFi and LTE Capabilities

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.

The Power of Commoditized WiFi

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.

Advanced Mesh: Mobile Ad Hoc Network (MANET)

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.

Self-forming, Self-healing

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.

Redundancy

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.

Real-time Topology Changes

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.

Low Latency Command and Control for Robotics

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.

Security and Encryption

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.

Multi-Hop Relay and Multi-Frequency Mesh

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.

HD Video with Multicast

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.

Always Pushing the Envelope

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.

Linux OS

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.

Special Frequency Bands for All Markets​

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.
