Chapter: Overview of the 1532 Access Point
Overview
The Cisco Aironet 1530 Series Outdoor Access Point (hereafter called the access point or AP) is a wireless outdoor access point which is designed for use in a variety of network configurations. The access point supports wireless client access, point-to-point bridging, point-to-multipoint bridging, and point-to-multipoint mesh wireless connectivity.
About the 1532 Access Point
The 1532 access point supports two radios (2.4-GHz and 5-GHz) and provides client access using the unlicensed RF Wi-Fi spectrum. The 2.4 GHz radio is used for client access and the 5 GHz radio can be dedicated for backhaul traffic or can used for both backhaul and client access. Depending on the radio, the access point can support 1 to 300 Mb/s data rates (for specific data rates, refer to Appendix D, “Access Point Data Sheet” ).
The access point is a standalone unit that can be wall, pole or tower mounted. The access point can also operate as a relay node for other access points not directly connected to a wired network. Intelligent wireless routing is provided by the patented Adaptive Wireless Path Protocol (AWPP). This enables each access point to identify its neighbors and intelligently choose the optimal path to the wired network by calculating the cost of each path in terms of signal strength and the number of hops required to get to a controller.
The access point can be configured, monitored, and operated through a Cisco wireless LAN controller (hereafter called a controller) as described in the Cisco Wireless LAN Controller Configuration Guide. The Cisco Wireless Mesh Access Points, Design and Deployment Guide, Release 7.6 describes how to plan and initially configure the Cisco mesh network, which supports wireless point-to-point, point-to-multipoint, and mesh deployments. The controllers use a browser-based management system, a command-line interface (CLI), or the Cisco Prime Infrastructure (PI) network management system to manage the controller and the associated access points. The access point supports hardware-based advanced encryption standard (AES) encryption between wireless nodes to provide end-to-end security. The access point can also be deployed in an autonomous mode and be configured via the CLI.

Statement 1052
Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement 1030
AP1532I (Internal Antenna)
The 1532I access point 802.11b/g/n radio is used primarily for local access and its 802.11a/n radio for wireless backhaul in the Mesh.
The 2 GHz b/g/n radio operates in 2.4 GHz ISM band. It supports channels 1-11 in the US, 1-13 in Europe, and 1-13 in Japan. It has 3 transmitters with a maximum total output power of 29 dBm for 802.11b/g/n operation. Output power is configurable for 8 levels in 3 dB steps. It has three receivers that enable maximum-ratio combining (MRC).
The 5 GHz a/n radio operates in the UNII-2 band (5.25 - 5.35 GHz), UNII-2 Extended/ETSI band (5.47 - 5.725 GHz), and the upper ISM band (5.725 - 5.850 GHz). It has two transmitters with a maximum total output power of 27 dBm depending on the regulatory domain. The total maximum output power for the upper ISM band is 27 dBm for A-domain. Tx power settings will change depending on the regulatory domain. Output power is configurable in 3 dB steps. Its three receivers enable maximum-ratio combining (MRC).
The 1532I access point is equipped with three integrated dual-band antennas with 3 dBi gain at 2 GHz and 5 dBi gain at 5 GHz.
AP1532E (External Antenna)
The 1532E access point is equipped with four N-type RF connectors. The 1532E can be configured via software to support dual band or single band antennas. When configured for dual band antennas, antenna ports 1 and 2 on the bottom of the unit (Figure 1-2) are used to support multiple input/multiple output (MIMO) operation on both 2.4 and 5 GHz radios. When using the Cisco Aironet AIR-ANT2547V-N or AIR-ANT2547VG-N omindirectional antennas, the antenna can be connected directly to the access point (Figure 2-16). If the antennas are remotely located, an appropriate low loss RF cable should be used.
Note Ensure that the antenna band mode is configured before the 1532E access point is installed.
When configured for single band antennas, antenna port 1 and antenna port 2 support MIMO operation for the 2.4 GHz radio, and antenna ports 3 and 4 (Figure 1-3) support MIMO on the 5 GHz radio. See the Cisco Wireless LAN Controller Configuration Guide for information on the software configuration.

Network Deployment Examples
The access point is a wireless device designed for wireless client access and point-to-point bridging, point-to-multipoint bridging, and point-to-multipoint mesh wireless connectivity. The access point provides 5-GHz backhaul capability to link with another access point to reach a wired network connection or to provide repeater operations for other access points.
The access point plays two primary radio roles: a root access point (hereafter called a RAP) or a mesh (non-root) access point (hereafter called a MAP), which is the default role of all access points. When the access point has a fiber or wired Ethernet connection to the controller (through a switch), the radio role is called a RAP. In order to be considered a RAP, the access point must be configured as a RAP. A RAP is a parent node to any bridging or mesh network. A controller can support one or more 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 and 5-GHz band. Client access on 5-GHz is called universal client access.
When the access point does not have a wired Ethernet connection to the controller (through a switch), the radio role is called a MAP. The MAPs have a wireless connection (through the backhaul interface) to other MAPs and finally to a RAP which has an Ethernet connection through a switch to the controller. MAPs may also have a wired Ethernet connection to a local LAN and serve as a bridge endpoint for that LAN (using a point-to-point or point-to-multipoint bridge connection).
Wireless Backhaul
The access point supports wireless backhaul capability using the 5 GHz radio to bridge to another access point to reach a wired network connection to a controller (see Figure 1-7). The access point connected to the wired network is considered a RAP in this configuration. The remote access point is considered a MAP and transfers wireless client traffic to the RAP for transfer to the wired network. Control And Provisioning of Wireless Access Points (CAPWAP) control traffic is also transferred over this bridged link.
Figure 1-7 Access Point Backhaul Example
Point-to-Point Bridging
The access points can be used to extend a remote network by using the 5 GHz backhaul radio to bridge the two network segments as shown in Figure 1-8. To support Ethernet bridging, you must enable bridging on the controller for each access point. By default this capability is turned-off for all access points.
Wireless client access is supported; however, if bridging between tall buildings, the 2.4-GHz wireless coverage area may be limited and possibly not suitable for direct wireless client access.
Figure 1-8 Access Point Point-to-Point Bridging Example
The access points can also support point-to-point bridging under autonomous mode. In this autonomous mode, the bridging can be done on the 2.4 or 5 GHz radio, but not both. In this mode, one access point is designated as the root and the other end is designated as the non-root bridge.
Figure 1-9 Access Point Point-to-Point Bridging in Autonomous Mode
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. Wireless client access can be provided over the bridging link; however, if bridging between tall buildings, the 2.4-GHz wireless coverage area may be limited and possibly not suitable for direct wireless client access. Figure 1-10 illustrates an example of access point-to-multipoint bridging.
Figure 1-10 Access Point to Multipoint Bridging Example
The access points can also support point-to-multipoint bridging under autonomous mode. In this autonomous mode, the bridging can be done on the 2.4 or 5 GHz radio, but not both. In this mode, one access point is designated as the root and the other end is designated as the non-root bridge.
Figure 1-11 Access Point to Multipoint Bridging in Autonomous Mode
Point-to-Multipoint 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. In the mesh network, the links between the access points are referred to as the backhaul links.
Intelligent wireless routing is provided by the Adaptive Wireless Path protocol (AWPP). This enables each MAP to identify its neighbors and intelligently choose the optimal path to the RAP with the wired network connection by calculating the cost of each path in terms of signal strength and the number of hops required to get to a controller with signal strength given priority since signal strength determines the data rate available for backhaul.
Figure 1-12 illustrates a typical mesh configuration using MAPs and RAPs.
Figure 1-12 Typical Mesh Configuration Using Access Points
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 1-13 illustrates a typical Layer-3 wireless network configuration containing access points and a controller.
