1.1 About the Motorola Solutions WiNG 5 Access Point Software

The WiNG 5 architecture is a solution designed for 802.11n networking. It leverages the best aspects of independent and
dependent architectures to create a smart network that meets the connectivity, quality and security needs of each user
and their applications, based on the availability of network resources including wired networks. By distributing
intelligence and control amongst access points, a WiNG 5 network can route directly via the best path, as determined by
factors including the user, location, the application and available wireless and wired resources. WiNG 5 extends the
differentiation Motorola Solutions access points offer to the next level, by making available services and security at every
point in the network. Access point managed traffic flow is optimized to prevent wired congestion and wireless congestion.
Traffic flows dynamically, based on user and application, and finds alternate routes to work around network choke points.
With this latest WiNG 5 release, the network can use access points to adapt to the dynamic circumstances of their
deployment environment. The WiNG 5 architecture provides a customized site-specific deployment, supporting the best
path and routes based on the user, location, application and the best route available (both wireless and wired). A WiNG
5 access point managed network assures end-to-end quality, reliability and security without latency and performance
degradation. A WiNG 5 access point managed network supports rapid application delivery, mixed-media application
optimization and quality assurance.
Deploying a new WiNG 5 access point managed network does not require the replacement of existing Motorola Solutions
access points. WiNG 5 enables the simultaneous use of existing architectures from Motorola Solutions and other vendors,
even if those other architectures are centralized models. A wireless network administrator can retain and optimize legacy
infrastructure while evolving to WiNG 5 as needed.
By distributing intelligence and control amongst access points, a WiNG 5 network can route data directly using the best
path. As a result, the additional load placed on the wired network from 802.11n support is significantly reduced, as traffic
does not require an unnecessary backhaul.
Within a WiNG 5 network, up to 80% of the network traffic can remain on the wireless mesh, and never touch the wired
network, so the 802.11n load impact on the wired network is negligible. In addition, latency and associated costs are
reduced while reliability and scalability are increased. A WiNG 5 network enables the creation of dynamic wireless traffic
flows, so bottlenecks can be avoided, and the destination is reached without latency or performance degradation. This
behavior delivers a significantly better quality of experience for the end user.
The same distributed intelligence enables more resilience and survivability, since access points keep users connected and
traffic flowing with full QoS, security and mobility even if a connection is interrupted due to a wired network or backhaul
problem.
When the network is fully operational, sources of interference or unbalanced wireless network loading can be
automatically corrected by the access point's Smart RF functionality. Smart RF senses interference or potential client
connectivity problems and makes the required changes to the channel and access point radio power while minimizing the
impact to latency sensitive applications like VoIP. Using Smart RF, the network can continuously adjust power and channel
assignments for self-recovery if an access point radio fails or a coverage hole is detected.
Additionally, integrated access point sensors, in conjunction with AirDefense Network Assurance, alerts administrators
of interference and network coverage problems, which shortens response times and boosts overall reliability and
availability of the access point managed network.
Network traffic optimization protects the network from broadcast storms and minimizes congestion on the wired network.
The access point managed network provides VLAN load balancing, WAN traffic shaping and optimizations in dynamic host
configuration protocol (DHCP) responses and Internet group management protocol (IGMP) snooping for multicast traffic
flows in wired and wireless networks. Thus, users benefit from an extremely reliable network that adapts to meet their
needs and delivers mixed-media applications.
Firmware and configuration updates are supported from one access point to another, over the air or wire, and can be
centrally managed by an access point in Virtual Controller AP mode. Controllers no longer need to push firmware and
configurations to individual access point, thus reducing unnecessary network congestion.
