BelAirs 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 PointBackhaul Links

BelAir system covers outdoor open areas or inside buildings.


8/36Slide 8

BelAirs 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


9/36Slide 9

BelAirs 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 sharedbackhaul 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 withinterferers


10/36Slide 10

Single Radio Mesh and VoIP

In single radio mesh systems, when onenode 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 thenumber of neighbors and their activity.

Increased latency and variable jitterreduces voice quality

Single radio and other mesh systems withshared backhaul

Single radio mesh and other shared

backhaul mesh systems cant supportvoice over 2 hops or more

Also impacts other multimedia applications

Multi-Radio Mesh and VoIP

BelAir multi-radio mesharchitecture

Dedicated point to point links betweennodes

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 differentchannels

Backhaul links on different channels

Slide 33

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-directionalantennas to send and receive to all theother 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 singleradio

Simple, but wont scale to a large system

Cannot support many broadband users

Mesh Options: Dual Radio

Each node has two radios

Access and backhaul are separateMesh 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 animprovement Solves the mesh forwarding problem

Mesh Options: Multi-Radio

Each node has multiple radios Client access and mesh backhaul arecompletely independent

Mesh formed with multiplepoint-to-point links, dedicatedradios, directional antennas

Backhaul is an independent networkoperating on multiple channels

Can run custom protocol

Independent backhaul links providegreater capacity

Point-to-point links enable greaterseparation of mesh nodes

Backhaul mesh has performance of wirednetwork
