[BelAir Networks builds carrier-grade wireless mesh network equipment that delivers video, voice, data, and high-speed Internet access throughout cities, campuses, apartment buildings, businesses, hotels and resorts. With over 150 deployments worldwide, BelAir is the only company delivering a complete and comprehensive wireless mesh product line.

Targeted at municipal networks, cable operators, cellular service providers and enterprise deployments, BelAir wireless mesh solutions integrate easily and transparently into existing network and physical infrastructures.

BelAir Networks wireless mesh networking solutions are built on a unique architecture that integrates wireless access with wireless backhaul in an innovative dual- or multi-radio mesh to provide a high-capacity wireless mesh network. BelAir's single-radio nodes also integrate seamlessly into the network offering a low-cost solution for data services coverage.

To create the wireless mesh, Belair Networks uses outdoor wireless internetworking platforms that can provide both indoor and outdoor coverage from an outdoor deployment. Backhaul radios in each node can be configured point-to-point or point-to-multipoint with directional antennas. Each node can connect to multiple others and the combined connections form the wireless backhaul mesh.

No additional switches, routers or cables are required to connect multiple platforms.

By using this approach, the BelAir Networks solution:

eliminates the need for cables, extra switches and routers to interconnect wireless mesh nodes
requires five to ten times fewer access points compared to indoor solutions
eliminates disruptive, in-building network deployment
reduces WLAN capital expenditures by up to 70%
reduces WLAN operating expenditures by up to 90%
eliminates T1, DSL and other backhaul costs
provides five to ten times more capacity and five times more coverage compared to traditional wireless mesh architectures.
Most importantly, by combining the best of cellular and WLAN networking, the BelAir Networks solution offers the lowest-cost wireless mesh network deployment on the market.

How It Works

In a BelAir Networks wireless mesh solution, each multi-radio node supports backhaul coverage in all directions using antennas in a circular array. The antennas have a high gain and a narrow horizontal beamwidth, which together with enhanced radio performance, provide significant reach extension.



The three backhaul radios in each platform can automatically connect to any one of the eight backhaul antennas with no need for manual pointing. The selection is done under software control via BelAir Networks patent pending autoantenna selection algorithm.

System availability is ensured through a combination of techniques:

The radio environment is constantly changing and the radios adapt to these changes on a packet-by-packet basis. In addition, dynamic power and data rate changes on individual radio links compensate for radio effects such as fading and shadowing.

Radio-aware routing algorithms choose the best route for traffic based on available capacity, latency and radio link performance.

To increase system up-time and minimize traffic outages, traffic from each broadband platform can be load balanced across a minimum of two routes to reduce the impact of link congestion and failure.

Alternate paths are continuously calculated and refreshed so that seamless re-routing of traffic can occur with minimal packet loss in the unlikely event of a link failure.
A BelAir wireless mesh can easily scale up to meet increased network demand. Or it can be scaled down to address lowest cost coverage requirements through the seamless integration of single- and dual-radio nodes. New nodes can be incorporated into the network automatically, without complex operator intervention.

A wireless mesh network can be deployed with a single egress point (point of presence). As usage increases and demand warrants, additional egress points can be added for increased capacity and redundancy through multi-homing.
