Data Sheet

Highly Scalable Mesh

The Cisco Outdoor Wireless Networking solution can scale to a few thousand mesh access points

with a cluster of up to 24 controllers each with up to 16 multiple Basic Service Set Identifiers

(BSSIDs). For large deployment, a Cisco 4400 Series controller can support up to 100 Cisco

Aironet 1520 mesh access points. Capacity in a mesh network can be increased conveniently by

adding the mesh access points at the edge of the network or by configuring more rooftop access

points in the network. As with all large scale deployments, a professional site survey is required to

determine the optimal number of access points required for best performance.

Applications

The Cisco Aironet 1522 is designed specifically for outdoor environments. It features antenna

connectors for extended range or coverage versatility and more flexible installation options. In

outdoor municipal wireless applications, for example, network operator can place Cisco Aironet

1522 mesh access points on buildings, or mount them on lamp posts, cable strands, and antenna

towers connected with a wired connection. Several uplink connectivity options such as Gigabit

Ethernet, fiber, and cable are supported on the Cisco Aironet 1522. This provides flexibility for

deploying the mesh access point anywhere in the community. The access point without wired

connection will use the 5-GHz radio to wirelessly connect to the other mesh access point.

The metal housing enclosure of the Cisco Aironet 1522 provides the rugged and extended

operating temperature range required in harsh outdoor, hazardous environments such as oil fields

and mining pits, where explosion may occur. The rugged enclosure allows the mesh access point

to maximize network uptime, remaining available and reliable even in severe weather conditions.

With the 802.3af compliant PoE feature, mesh access points can connect to other IP devices such

as video surveillance cameras and IP sensors. This allows easy and quick deployment of mission-

critical monitoring applications at locations where infrastructure does not exists. Video cameras

and monitor sensors can take advantage of the mesh access point to connect to the network, and

data can be transmitted via secure Wi-Fi. With internal battery power backup, the mesh access

point will continue to function reliably even when the power is temporarily down. This allows the

network operator to continue to monitor any incident while the power is being restored.

Adaptive Wireless Path

Protocol (AWPP)



Forms a wireless mesh network between nodes.



Designed specifically for a multiradio platform to handle acute environmental

interference as well as self-interference, optimizing



Dynamically optimizes traffic routes between nodes for high network resiliency and high

system capacity.



Self-heals from interference or outages, reducing management costs.



Optimal Parent Selection scans all available channels to ensure that the mesh

optimizes network capacity.



Exclusion listing provides an advance intelligence at the access point to exclude as a

parent any access point through which a link to the controller cannot be established.

Bridging



Bridges remote networks over wireless in a point-to-point or point-to-multipoint

configuration, eliminating leased lines or providing an alternative backhaul.



Allows remote peripherals, such as security cameras, to be bridged to the network.



Wireless link-distance adjustment allows the 802.11 protocols to be tuned for optimal

performance over extended bridging distances.
