Toll-Quality Voice and Streaming Video over Wireless LAN

As more enterprises move from purely data-driven applications and incorporate voice over IP (VoIP) and streaming video delivery, the demands for quality of service and assured application delivery rise commensurately. Indeed, these applications can literally break a wireless LAN that is not designed for application awareness and automatic flow control.

Aruba's Adaptive Radio Management technology encompasses many technological innovations designed specifically to address the needs of toll-quality voice and streaming video applications. The first of these is application awareness, the ability to detect the type of application and coordinate suitable network conditioning to ensure proper packet delivery. In an Aruba network this process occurs automatically and requires no user intervention.

Adaptive interference management makes the best use of available 802.11n and 802.11a/b/g radio channels to provides a clear path for signaling. Air-time bandwidth control adjusts available bandwidth on a packet-rate or air-time basis to prevent slow clients from consuming too much channel time.

Mobile clients need to be switched from access point to access point in an efficient and expeditious manner. Aruba offers instantaneous hand-offs to allow undisturbed roaming without hand-off delays or dropouts, and automatic load balancing to ensure that roaming clients don't bog down access point performance.

Fast Roaming Is Essential For Undisturbed Voice Roaming

The net result is that users of single and dual-mode handsets can roam with confidence. In the latter case, handsets can be used with Aruba's enterprise FMC solution to seamlessly roam in and out of cellular networks, adding a new dimension of user convenience and overhead cost-control.

Aruba provides several unique features for streaming video and video surveillance. Secure Enterprise Mesh technology allows cameras to be located wherever they are needed without adding new network wiring. QoS for video-over-wireless LAN, secure tunneling for video streams, simple camera provisioning and network integration, and video analytics together ensure the timely delivery of high quality video.

Indoor and Outdoor Streaming Video Can Be Provided On A Standalone Basis or Integrated Into an Existing Wireless LAN

For customers that desire peer-to-peer communications between devices, say for voice communications, Secure Enterprise Mesh allows traffic forwarding within the mesh without backhauling data through the Mobility Controller. Unique to Aruba, cryptographic termination is distributed based on the application type. Keys are distributed only to those mesh access points that need to operate in the peer-to-peer mode, minimizing opportunities to compromise security relative to alternatives mesh networks that perform hop-by-hop encryption and store keys in every access point.

Peer-to-Peer Networking Between Without Controller Backhaul

Aruba's ARM technology enables high-availability wireless LANs that provide an ideal solution for voice and video applications. Intelligent access points work in concert with Mobility Controllers to ensure reliable voice and video application delivery, while Secure Enterprise Mesh networking can dramatically lower the cost of video installations and reach otherwise inaccessible locations. Optimized packet management, automatic network adaptation, and QoS provide an exceptional user experience and a level of network resiliency and robustness not found elsewhere.
