• First generation (most mesh products)– Geometrically-increasing throughput loss from hop to hop

• Second generation (aka dual radio)– Separate bands for backhaul and user traffic

• Third generation (multi-radio backhaul)– Separate radios for backhaul uplink and downlink– Dynamic channel management– The keys are traffic, interference, and spectrum management– Addressed by key patent (7,420,952)

Third Generation Meshes


Third Generation Structured MeshTM

Separate Contention Domains


• US Patent 7,420,952 awarded Sep 2008.“High Performance Wireless Networks Using Distributed Control”

Essential mesh capabilities, including• Throughput and latency management• Dynamic backhaul load management• Dynamic network topology management• Dynamic channel management• Local interference management• Self-configuration• Fault tolerance• Traffic forwarding

Not limited to Wi-Fi • UWB, WPANs, WiMAX, …

• US Patent 7,583,648 awarded Sept 2009“Managing Jitter and Latency on Wireless LANs”

Focus on Efficient VOIP transmission over wireless Mesh• Aggregated routing and delivery of VOIP packets• Novel approach to increase VOIP capacity through timed aggregation • Software extensions of VOIP phones to support increased VOIP capacity • Patent claims address other latency sensitive packet transmissions (e.g. Video)

Key Intellectual Property

Additional Patents Filed and in Process


• Extremely high performance, over many hops, low latency per hop– High bandwidth - minimal delay for video, data– Proven superior in extensive testing by SPAWAR, USAF– Proven communication inside underground mine 40+ hops deep

• Distributed dynamic radio intelligence– Cooperative “radio robots” inside node automate mesh set-up– Network reuses channels for maximum performance– Automated interference avoidance works at multiple levels

• Exceptional mobility capabilities– Scanning subsystem continuously monitors RF environment– Dynamic network forms and reforms rapidly

• Radio-Agnostic Architecture– Hardware Abstraction Layer treats radio as a port– Device Abstraction Layer supports 2.4G, 4.9G, 5.8G radio– Permitted channel list is dynamic and remotely configurable

• Platform-Agnostic Software– Runs on multiple versions of Linux – Being ported to Windows (Laptops) and WinCE/WM (Smartphones)
