Data Sheet
Layer 2 or Layer 3 Network Operation
Just as the Cisco Unified Wireless Network solution allows the LWAPP access points to
communicate with the controller via a Layer 2 (L2) or Layer 3 (L3) network, this flexibility is
extended to the outdoor wireless mesh network.
Highly Scalable
The Cisco Outdoor Wireless Networking solution can scale to 24 controllers each with up to 16
multiple Basic Service Set Identifiers (BSSIDs) and 256 VLANs. Each 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.
Applications
The Cisco Aironet 1520 Series 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 1520 Series 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 1520 Series.
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 for backhaul to the network.
The metal housing enclosure of the Cisco Aironet 1520 Series provides the ruggedness 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.
