MeshDynamics Third Generation Mesh Architecture: Earlier-generation mesh networking products perform poorly in multi-hop (node-to-node relay) environments. MeshDynamics' patented low latency multiple radio wireless mesh preserves high performance [over multiple hops] that's been available only in wired networks until today.

1. Wireless for the Outdoor EnterpriseTM
High Level Overview

2. Third Generation Meshes
• 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)
