  • Page 4: Introduction To The Access Point

    Statement 1040 Introduction to the Access Point The Cisco Aironet 1520 Series Outdoor Mesh Access Point (hereafter called the access point) is a modularized outdoor access point designed for service in mesh networks. The access point can be configured for one or two radio operation. Its 802.11b/g radio is used primarily for local access and its 802.11a radio is used to provide wireless backhaul in the mesh.

  • Page 16: Wireless Backhaul

    RAPs, each one parenting the same or different wireless networks. There can be more than one RAP for the same mesh network for redundancy. RAPs and MAPs can support wireless clients on the 2.4-GHz band. When the access point does not have a wired Ethernet connection to the controller (through a switch), the radio role is called a MAP.

  • Page 17: Point-To-Multipoint Bridging

    Figure 5 Point-to-Point Bridging Example Point-to-Multipoint Bridging The access points can be used as a RAP to connect multiple remote MAPs with their associated wired networks. By default this capability is turned-off for all access points. To support Ethernet bridging, you must enable bridging on the controller for each access point.

  • Page 18: Mesh Network

    Mesh Network The access point is typically deployed in a mesh network configuration. In a typical mesh deployment, one or more RAPs have a wired network connection through a switch to a controller. Other remote MAPs without wired network connections use the backhaul feature to optimally link to a RAP that is connected to the wired network.

  • Page 19: Layer 3 Network Operation

    The access points support Layer 3 network operation. Access points and controllers in Layer 3 configurations use IP addresses and UDP packets, which can be routed through large networks. Layer 3 operation is scalable and recommended by Cisco. Figure 8 illustrates a typical Layer-3 wireless network configuration containing access points and a controller.

  • Page 20: Site Surveys

    Site Surveys Cisco recommends that you perform a site survey before installing the equipment. A site survey reveals problems that can be resolved before the network is operational. Because 802.11a is unlicensed, there may be sources of interference from other 802.11a wireless devices (especially in multi-tenant buildings) that could degrade your 802.11 signals.
  • Page 21 To avoid receiver damage and PER degradation, you can use one of the following techniques: • Separate the omnidirectional antennas by at least 2 ft (0.6 m) to avoid receiver damage or by at least 25 ft (7.6 m) to avoid PER degradation. These distances assume free space path loss and are conservative estimates.
