  3. BelAir Networks Vision • Wide Area Wi-Fi • Complete solution for metro scale WI-FI infrastructure • Wi-Fi access today, but other access technologies possible • Wi-Fi, WiMAX, cellular can exist on the same platform • Carrier-grade, outdoor solution • Integrated wireless mesh backhaul and wireless access • Delivers broadband data, voice and video services • Software to manage multiple applications • Target Markets • Metro Wi-Fi, Hospitality, Higher Education Campuses, Transportation & Logistics, Government, Multi-Dwelling Units

  4. BelAir Mesh Applications

  5. Complete Wide Area Wi-Fi BelAir provides complete infrastructure for Wide Area Wi-Fi. Includes integrated wireless backhaul and wireless access.

  6. Enterprise Performance, Metro Scale • Standard Wi-Fi Clients • Enterprise applications • VoWi-Fi • Enterprise security • Multiple SSIDs and VLANs • Mobility Metro coverage for Wi-Fi with no compromises.

  7. BelAir’s Outside In Coverage • Directional access antennas project coverage in from the outside • Complete building coverage with fewer nodes • Eliminates need for indoor wired network to interconnect APs 54 Mbps Point to Point Backhaul Links BelAir system covers outdoor open areas or inside buildings.

  8. BelAir’s Mesh Technology • Multiple Point-to-Point Mesh with Wi-Fi Access • High capacity, robust, secure wireless backbone • Reduces backhaul costs • Enables wireless access nodes to be placed where needed • Provide Wi-Fi coverage inside buildings from the outside

  9. BelAir’s Mesh Approach • Multi-radio mesh with multiple point-to-point wireless backhaul links • Access is 2.4 GHz Wi-Fi at 11 Mbps up to 54 Mbps • Backhaul is multiple point-to-point 5 GHz links • Up to 3 independent 54 Mbps links • Capacity • Highest capacity wireless mesh • Performance similar to wired links • More than 10 times capacity of single radio mesh • 3 times the capacity of dual radio mesh • Latency • BelAir has lowest latency • BelAir system can support voice and video • Dual radio and single radio mesh have shared backhaul so latency is poor and unpredictable • Interference and co-existence • BelAir is a better citizen sharing the unlicensed bands and has more flexibility in dealing with interferers

  10. Single Radio Mesh and VoIP • In single radio mesh systems, when one node transmits, its neighbors must listen. • All nodes use same channel • Each node must buffer packets until network is not busy • Buffering represents delay • Backhaul links between APs are ‘transient’ • Delay and jitter vary depending on the number of neighbors and their activity. • Increased latency and variable jitter reduces voice quality • Single radio and other mesh systems with shared backhaul • Single radio mesh and other shared backhaul mesh systems can’t support voice over 2 hops or more • Also impacts other multimedia applications Transmitting Single Radio Mesh Listening and Blocked f1 f1 f1 f1 Buffers Data Link Not Made, Node is Blocked Listening and blocked f1 Listening But No Data Arriving

  11. Multi-Radio Mesh and VoIP • BelAir multi-radio mesh architecture • Dedicated point to point links between nodes • Stable and persistent links • No buffering is required • Latency is low (1-2 ms delay per hop) • Jitter is independent of network topology • Parallel operation is possible • Wireless access and backhaul on different channels • Backhaul links on different channels • Not a shared backhaul network • Enables voice and other multimedia applications mixed with data Transmitting Multi-Radio Mesh Listening and Ready f1 f2 f3 Backhaul Links are Persistent f1 f2 Listening and ready f3 Listening and Ready BelAir system enables VoWi-Fi across large mesh.

  33. f1 f1 f1 f1 f1 Mesh Options: Single Radio • 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 • Backhaul is a shared network • Mesh nodes and clients share available bandwidth • System capacity is very low • Latency is high and unpredictable • Most mesh products today are single radio • Simple, but won’t scale to a large system • Cannot support many broadband users Unacceptable For Permanent Broadband Infrastructure

  34. a1 a1 a1 a1 a1 f1 f1 f1 f1 Mesh Options: Dual Radio • Each node has two radios • Access and backhaul are separate • Mesh is formed using omni-directional antennas • Multipoint-to-multipoint • Backhaul is a shared network operating on a single channel • System capacity is low • Dual radio mesh is an improvement • Solves the mesh forwarding problem • Still limited capacity and scalability • Works for small networks • But… Won’t Support Voice Over Wi-Fi—Latency High/Unpredictable

  35. Mesh Options: Multi-Radio • 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 • Can run custom protocol • Independent backhaul links provide greater capacity • Point-to-point links enable greater separation of mesh nodes • Backhaul mesh has performance of wired network Coverage And Capacity Scale To Large Network

  36. Capacity Comparison • Capacity of Multi-Radio system constrained by backhaul • Can increase capacity of multi-radio system by adding more wired egress points
