Technology Overview

Motorola’s Mobility Enabled Access (MEA) technology leverages patented and proven routing techniques originally developed for battlefield communications. By pushing intelligence and decision making to the edge of the network, high performance and scalable broadband networks can be cost effectively deployed. This technology is widely deployed and powers some of the largest mobile mesh networks in the world.

Mesh Networking 101
Mesh networking is typically implemented in two basic modes: infrastructure and/or client meshing. To gain the maximum benefit that meshing can offer, both modes need to be supported simultaneously and seamlessly in a single network.

Infrastructure meshing creates wireless backhaul mesh among wired Access Points and Wireless Routers. This reduces system backhaul costs while helping increase network coverage and reliability.

Client meshing enables wireless peer-to-peer networks to form between and among client devices (i.e., end users) and does not require any network infrastructure to be present. In this case, clients can hop through each other to reach other clients in the network.

Motorola’s Mesh Networking Products Offer a Complete Solution
Motorola’s MEA technology supports both infrastructure and client meshing. MEA’s infrastructure meshing creates a robust and scalable network, while client meshing enables end users to instantly form a broadband wireless network among themselves – with or without the inclusion of network infrastructure.

Motorola’s Multi-Hopping technology turns every client device into a router/repeater. As users join the network they improve network coverage and increase network throughput. MEA networking is unique in that it supports Continuous Mesh Routing™. That is, it supports simultaneous operation of infrastructure and client meshing while it also allows clients to move seamlessly between infrastructure-based and client-based peer-to-peer networks.

Self-forming, self-healing routing intelligence distributes clients between Access Points, eliminating bottlenecks and improves overall network performance. MEA technology also improves network robustness, as clients can hop to alternate Access Points if their current Access Point is congested or fails. It also lets clients form large, ad hoc peer-to-peer networks anywhere, anytime. Peer-to-peer networking reduces the demand on network Access Points, freeing up capacity for other users. All these capabilities create low-cost, seamless and simple to deploy wireless PAN, LAN or WAN solutions.


Motorola’s Ad Hoc Networking Technologies

Mesh Scalable Routing (MSR™)
The first core technology powering MOTOMESH solutions is Mesh Scalable Routing (MSR™) protocol. The MSR protocol is more than a routing algorithm, it is a complete mobile ad hoc networking solution that can mesh enable any 802.xx radio platform.

MSR technology utilizes an optimized and proven hybrid ad hoc routing algorithm that combines both proactive and reactive routing techniques. This enables support for high speed mobility, unmatched scalability and low messaging overhead. The result is a high performance solution that automatically adapts to varying network conditions, degree of client mobility and relevant RF environmental conditions on a packet by packet basis. Initially designed using high fidelity modeling, MSR has been optimized on large scale real world deployments.

Adaptive Transmission Protocol (ATP™) Service
The second core technology leveraged by all MOTOMESH products is Adaptive Transmission Protocol (ATP™) service. ATP services tightly bind the MSR protocol to the underlying radio platform. It interprets platform specific RF parameters and provides a radio agonistic, yet radio aware view of current RF conditions. It also works with the MSR protocol to adapt and optimize route selection, data rate modulation, and power output based on capabilities available on each specific radio platform MAC and Phy implementation. ATP also detects and deals with asymmetric RF links between nodes, a frequent occurrence in real world wireless networks.

In short, MSR and ATP technology work together to create a cross-layer optimized mesh solution for high performance and self-configuring wireless networks. The intellectual property and techniques employed in these core technologies are protected by an extensive portfolio of patents.

Other Motorola Mesh Networking Technologies

Quadrature Division Multiple Access (QDMA®) Radio Platform
As part of its exclusive license to the ITT/DARPA mobile ad hoc networking Intellectual Property and patent portfolio, Motorola received the rights to the Quadrature Division Multiple Access (QDMA™) mobile radio platform. The QDMA radio is designed and optimized for mobile ad hoc broadband networking. Its multi-channel MAC and Phy are optimized to meet the scalability and reliability required in mission critical mesh networks. RF challenges encountered in wide area mobile networks such as Doppler shifting, rapid Raleigh fading and Multipath are handled efficiently by the QDMA radio. QDMA solutions have been successfully deployed in Public Safety, transportation and Homeland Security mobile data networks.

Multi-Radio Mobile Broadband
Taking a unique approach to municiple networking, Motorola has developed MOTOMESH Quattro, a multi-radio mobile broadband solution. By putting four radios into a single access point, this technology allows a municipality to deploy 4 seperate networks with a single installation. Every MOTOMESH Quattro access point contains two standards compliant 802.11 (WiFi) radios and two of Motorola’s acclaimed Mobility Enabled Access (MEA) mobile broadband radios. One set of WiFi and MEA radios operate in the unlicensed 2.4GHz band. The other operates in the 4.9GHz public safety band. Each radio's network connection and power source is completely seperate from the others, making it impossible for them to overwhelm each other with network congestion. A municipality can now offer seperate access to Public Works, Public Safety agencies and the general public within a single deployment.

Mesh Positioning System (MPS™)
Some of the world’s largest Public Safety agencies are trialing Mesh Positioning System (MPS™) products as part of their MEA/QDMA mobile broadband network solutions. MPS technology provides high precision position location for outdoor and indoor applications – something GPS can’t match. And unlike GPS, MPS software can be configured to provide position information to the end user being located, as well as to neighboring users and/or central network monitoring points. MPS is ideal for Search & Rescue, Asset Management and Automatic Vehicle Location (AVL) applications.
