The Extreme Networks Wireless Mobility 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. The Wireless Mobility 5 software is a Third Generation WLAN solution which
incorporates the best of both the first generation Autonomous Access Point WLAN and the
second generation Centralized Controller Based WLAN.
The control plane is now distributed between the Access Points and the controllers. The
network administrator has the flexibility of directing the data plane either being forwarded
directly from the Access Points, or through the controllers. By distributing intelligence and
control between the wireless controllers and APs, the Wireless Mobility 5 network can route
directly through the best path, as determined by factors including the user, location,

protocol. Extreme Networks Wireless Mobility 5 networks extend the differentiation that
Adaptive APs offered to the next level by now having the services and security available at
every point in the network. The traffic flow is optimized to prevent wired congestion as
well as wireless congestion. Traffic flows dynamically, based on user and application, and
finds alternate routes to work around any possible network choke points. Mixed-media
application optimization is the hallmark of Extreme Networks Wireless Mobility 5 networks.
Extending the indoor network to the outdoors increases the need to guard against
unwanted intruders and attackers, and monitor network performance and availability. In
addition to industry standard security for clients and radio backhaul, the Altitude 4760

An Access Point can function as a Wireless Intrusion Protection System (WIPS) sensor and
upload sensor mode operation information to a dedicated WIPS server. WIPS protects your
wireless network, mobile devices, and traffic from attacks and unauthorized access. WIPS
provides tools for standards compliance and around-the-clock 802.11a/b/g/n wireless
network security in a distributed environment. WIPS allows administrators to identify and
accurately locate attacks, rogue devices, and network vulnerabilities in real time and
permits both a wired and wireless lockdown of wireless device connections upon
acknowledgement of a threat.
Capacity in video surveillance solutions is critical to the performance of many networks
designed to monitor and provide safety. To assist with the deployment of video surveillance
networks where the camera application resides, the Altitude 4760 Series Access Point offers
band unlocked radio flexibility. The user can choose between 2.4 GHz, 5 GHz, and 4.9 GHz
bands for the radio type. The AP4760 supports 3x3 MIMO technology, reaching a maximum
data rate of 300 Mbps to maintain high performance and better quality of transmission.
The Altitude 4760 Series Access Point is designed to optimize network availability through
preemptive intelligence which dynamically senses weak or failing signals, securely moves
mobile users to alternate APs, and boosts signal power to automatically fill RF holes and
ensure uninterrupted mobile user access.
The Altitude 4760 Series Access Point band unlocked radios allow flexibility and
deployment options for the public safety market. The powerful radio increases coverage,
performance, and obstruction penetration for outdoor use. Receiver sensitivity is increased
proportionally so users have an increased ability to maintain high performance access for
mobility and client devices in the network.
