The smartBridges airPoint XO is a LongRangeTM IEEE 802.11b compliant professional access point with built-in bandwidth

management. It distributes bandwidth control function over the network, thus improving performance and robustness of Wireless Wide Area Networks (WWANS). The airPoint XO manages network traffic data to allow optimal bandwidth allocation, pricing and customer management. With remote management features, carrier class protection and standards compliance, the airPoint XO lends Wireless ISPs (WISPs) the unique capability to manage wireless networks effortlessly and profitably.

Bandwidth Management for increased ROI

The airPoint XO provides bandwidth throttling of upload/download streams. The bandwidth control can be done using static tables or dynamically by RADIUS, along with authentication. The Wireless ISP can profile subscribers based on speed limits and identify bandwidth usage patterns. This opens up customer segmentation possibilities, leading to revenue maximization. The airPoint XO provides traffic statistics. This helps the WISP to observe the behavior of network devices, traffic load fluctuations and other events, making it much easier to troubleshoot any problems, which might occur. The information available helps the WISP to optimize bandwidth utilization. WISPs can now easily provide services to more subscribers.

Easy Scalability & Roaming

By distributing the bandwidth management function from the centralized NOC out to individual airPoint XO access points, it is now possible to design scalable wide area networks. Bandwidth traffic policies can be set remotely from a central NOC. This avoids the need for backhauling all the data traffic to a single place, thus averting a choke point. All access points in the network controlled by one NOC not only brings convenience to network management but also enables mobile users to avail easy roaming facility. Roaming users can cross over seamlessly from one cell to another within the same WISP network, without the need for authentication at every cross-over.

Automatic Client Discovery and Authentication

The airPoint XO supports MAC/IP address based authentication. The devices on the network are automatically discovered and built into a tree-topology for easy management. The airPoint XO also supports a one-time authentication of clients. Repeat users are authenticated automatically when they log on to the network. The WISP has full control of the network to ensure that unauthorized users don't have access to network facilities.
