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 missioncritical 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.
