Mesh Types C 148 Channel 11 C 148 Channel 6 Channel 1 C 148 Channel 11 Single radio – Shared Lowest cost to cover Best effort data services Dual radio – Shared Multi radio – Switched Compromise Data and some voice Highest performance Multi-media services Not all meshes are created equal ! BELAIR NETWORKS CONFIDENTIAL 10 BDMF 00001 -A 02

Mesh Options: single radio shared mesh • Each node has a single radio § Access and backhaul share radio § All nodes tune to same frequency • Mesh is formed using omni-directional antennas to send and receive to all the other nodes within range § Mesh nodes and clients share available bandwidth § Backhaul is a shared network f 1 § System capacity is very low f 1 § Latency is high and unpredictable • Most mesh products today are single radio f 1 § Simple, but won’t scale to a large system • • Cannot support many broadband users Not usable for Carrier Grade Voice f 1 • Think of this like a hub or shared media Ethernet Low capacity coverage only No carrier-grade voice due to high latency and jitter BELAIR NETWORKS CONFIDENTIAL 11 BDMF 00001 -A 02

Mesh Options: dual radio shared mesh • Each node has two radios § Access and backhaul are separate § 2 frequency bands used • Mesh is formed using omni-directional antennas § Multipoint-to-multipoint f 11 f 6 a 1 f 11 § Backhaul is a shared network operating a 1 on a single channel § System capacity is low f 1 a 1 f 6 a 1 • Dual radio mesh is an improvement § Removes the client device from the forwarding equations • Still limited capacity and scalability, works for small networks • Not suited for voice • This works like a hub as well Low capacity coverage only Limited carrier-grade voice due to high latency and jitter BELAIR NETWORKS CONFIDENTIAL 12 BDMF 00001 -A 02

Mesh Options: multi radio switched mesh • Each node has multiple radios § Client access and mesh backhaul are completely independent • Mesh formed with multiple point-to-point links, dedicated radios, directional antennas § Backhaul is an independent network operating on multiple channels • Independent backhaul links provide greater capacity • Point-to-point links enable greater separation of mesh nodes § Backhaul mesh has performance of wired network • Think of this like an Ethernet Switch Coverage and capacity scale to large network Delivers voice, video, TDM and data BELAIR NETWORKS CONFIDENTIAL 13 BDMF 00001 -A 02
