Overview

The Cisco Aironet 1550 Series Outdoor Mesh Access Point (hereafter called the access point or AP) is a modularized wireless outdoor access point designed for use in a mesh network. The access point also supports wireless client access, point-to-point bridging, point-to-multipoint bridging, and point-to-multipoint mesh wireless connectivity.

About the 1552 Access Point

The 1552 access point supports two radios (2.4-GHz and 5-GHz) and provides client access without the need for a license. The 5-GHz radios are primarily used for backhaul operations to reach a wired network and the 2.4-GHz radio is used for wireless clients. 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 Specifications” ).

The 1552 access point supports the modularity of the 1520 series and allows flexibility in radio configuration. In addition to full interoperability with 802.11n clients, the 1552 access point interoperates with legacy clients and offers enhanced backhaul performance. The 1552 access point can also be configured with an integrated DOCSIS 3.0/Euro DOCSIS 3.0 cable modem.

The access point is a standalone unit that can be cable strand 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 is 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 7.3 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.

Multiple Radio Operation

The 1552 access point supports simultaneous dual-radio operation using a 2.4-GHz 802.11b/g/n multiple input/multiple output (MIMO) radio and a 5-GHz 802.11a/n MIMO radio. The 2.4 GHz radio supports channels 1 to 11 in US, 1 to 13 in Europe, and 1 to 13 in Japan. It has two transmitters with a maximum total output power of 25 dBm for 802.11b/g/n operation. Output power is configurable to 5 levels. It has three receivers that enable maximum-ratio combining (MRC).

The 5-GHz radio operates in the UNII-2 band (5.25 – 5.35 GHz), UNII-2 Extended/ETSI band (5.47 – 5.725 GHz), upper ISM band (5.725 – 5.850 GHz), and the Extended India Band (5.85 – 5.875 GHz). It has two transmitters with a maximum total output power of 26 dBm for UNII-2 and Extended/ETSI bands. The total maximum output power for the upper ISM band is 28 dBm. Output power is configurable for 5 power levels in 3 dB steps. The three receivers enables maximum-ratio combining (MRC).

Antenna Configurations

The 1552 access point supports a variety of antennas designed for outdoor use with radios operating in the 2.4-GHz and 5-GHz frequency bands. In addition to an integrated antenna array, the 1552 supports the external antennas listed in the following sections.

Two mounting configurations are available, the cable strand mount and the pole mount (refer to “Mounting the Access Point” section.)

Using an optional antenna mounting bracket kit, the directional antennas AIR-ANT2413P2M-N and AIR-ANT5114P2M-N can be mounted directly on an access point in a strand mount or pole mount environment. The antenna bracket kit contains four bracket sections and fasteners that you can assemble in multiple configurations to position and aim the directional antenna in a range of positions. For more information on mounting the antenna with the optional mounting bracket, refer to Installing Directional-Antenna Mounting Kits on Cisco 1550 Series Outdoor Mesh Access Points.

The AIR-CAP1552E-x-K9 model must always be operated with the three external antennas attached. Figure 1-10 shows the antenna port locations for model 1552E.

Low Profile Dual-Band 2.4/5-GHz Omni Antenna Array

The Low Profile Dual-Band 2.4/5 GHz Omni Antenna Array has the following basic features:

  • Contains an array of three dual-band omni antennas—The three omni antennas are contained within this single radome, which greatly reduces the antenna’s visual footprint and reduces the possibility of snagging the antenna on the cable bundle, the RF cable, or test cables.
  • Operates over both 2.4 GHz and 5 GHz bands—Each of the three omni antennas is a dual-band antenna, covering both the 2.4–2.5 GHz band, and the 5.2–5.9 GHz bands.
  • Gain of about 2 dBi at 2.4 GHz, 4 dBi at 5 GHz.

The access point POC cable modem configuration contains an internal cable modem for connection to the cable network from the pole-mounted cable lines. The access point can be powered using the 40-to 90-VAC (quasi-square wave AC) power provided by the cable network.

The cable modem supports these main features:

  • Data Over Cable Service Interface Specifications (DOCSIS)3.0
  • Backward compatibility with existing DOCSIS 1.1 and 1.0 networks

Ethernet (PoE) Ports

The access point supports an Ethernet uplink port (POE-In) and a downlink port (POE-Out). The access point PoE-in port uses an RJ-45 connector (with a liquid tight adapter) to link the access point to the 10/100/1000BASE-T network. The Ethernet cable is used to send and receive Ethernet data and to optionally supply inline 56-VDC power from the power injector.


Note When a 1552E or 1552EU access point is powered by PoE, the PoE-Out port is not active.


The access point PoE-out (10/100/1000BASE-T) port uses an RJ-45 connector to provide LAN connectivity and IEEE 802.3af power to a single peripheral customer device, such as a camera or sensor gateway. The PoE-out port should not be connected to a switch or hub. The Ethernet MAC addresses are printed on the bottom of the access point under the LEDs.


Note The PoE-out port is disabled when the access point is powered by the power injector.



Tip The access point senses the Ethernet and power signals and automatically switches internal circuitry to match the cable connections.



Warning To reduce the risk of fire, use only No. 26 AWG or larger telecommunication line cord. Statement 1023


The Ethernet cable must be a shielded outdoor rated Category 5e (CAT5e) or better cable. The access point senses the Ethernet and power signals and automatically switches internal circuitry to match the cable connections.


Caution To provide inline PoE, you must use the 1500 power injector (AIR-PWRINJ1500-2=). Other power injectors, PoE switches, and 802.3af power sources cannot provide adequate power, which may cause the access point to malfunction and cause possible over-current conditions at the power source.

Fiber Option


Warning Class 1 laser product. Statement 1008


The factory-orderable fiber option provides a fiber input and output capability. Fiber data is transmitted and received over a single-strand fiber cable, which is connected to the access point using these SFP modules:

  • 100BASE-BX10-U fiber Rugged small-form factor pluggable (SFP) module
  • 1000BASELX single-mode Rugged SFP module
  • 1000BASESX multimode Rugged SFP module
  • EPON ONU Rugged SFP module

Note SFP modules are not hot-swappable.


The access point has one fiber connection, located on the bottom of the unit (shown on Figure 1-1). Client data is passed to the network controller through the fiber connection via a fiber-capable switch. Configuration information can be found in the controller configuration guide of the controller you are using.

GPS Option

A GPS module is required to accurately track the location of the AP and report it to the controller. to provide location information for Cisco's AIR-CAP 1552I/C/CU/E/EU/H product line.

For information on routing and securing the cable for the GPS antenna, refer to the 1550 Series GPS Hardware Mounting Guide .

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 (RAP) or a mesh (non-root) access point (MAP), which is the default role of all access points. When the access point has a fiber or wired Ethernet or cable connector 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, fiber-optic, or cable connection to the controller, 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 with an Ethernet or cable connection through a switch to the controller. MAPs can 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 1-22). 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 1-22 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 1-23. 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 1-23 Access Point 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. 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 1-24 illustrates an example of access point-to-multipoint bridging.

Figure 1-24 Access Point to Multipoint Bridging Example

 

 

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 1-25 illustrates a typical mesh configuration using MAPs and RAPs.

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 1-26 illustrates a typical Layer-3 wireless network configuration containing access points and a controller.
