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.

CHAP T ER

OL-24247-01

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.

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

Hardware Features

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.

• Cisco Light Gray weatherproof radome for outdoor operation.

Figure 1-12 shows an integrated low-profile dual-band (2.4 GHz and 5 GHz) 3-element array antenna

built-in only on models AIR-CAP1552I-x-K9 and AIR-CAP1552C-x-K9.

Chapter 1 Overview

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).

Network Deployment Examples

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.

OL-24247-01

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.

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.

Chapter 2 Installing the Access Point

Caution Before connecting or disconnecting a power cord, you must remove AC power from the power cord using

a suitable service disconnect.

For additional important safety instructions for AC power cords, refer to the AC Power Cords for Cisco Aironet 1550 Series Outdoor Mesh Access Points document that shipped with your AC power cords.

For safety and to achieve a good installation, please read and follow these safety precautions:

• Select your installation site with safety, as well as performance in mind. Remember: electric power

lines and phone lines look alike. For safety, assume that any overhead line can kill.

• Call your electric power company. Tell them your plans, and ask them to come look at your proposed

installation.

• Plan your installation carefully and completely before you begin. Successful raising of a mast or

tower is largely a matter of coordination. Each person should be assigned to a specific task and should know what to do and when to do it. One person should be in charge of the operation to issue instructions and watch for signs of trouble.

• When installing the access point and antennas, remember:

–

Avoiding Damage to Radios in a Testing Environment

Do not use a metal ladder.

–

Do not work on a wet or windy day.

–

Do dress properly—shoes with rubber soles and heels, rubber gloves, long sleeved shirt or jacket.

• Use a rope to lift the access point. If the assembly starts to drop, get away from it and let it fall.

• If any part of the antenna system should come in contact with a power line, do not touch it or try to

remove it yourself. Call your local power company. They will remove it safely.

If an accident should occur, call for qualified emergency help immediately.

Avoiding Damage to Radios in a Testing Environment

The radios on outdoor units (bridges) have higher transmit power levels than radios on indoor units (access points). When you test high-power radios in a link, you must avoid exceeding the maximum receive input level for the receiver. At levels above the normal operating range, packet error rate (PER) performance is degraded. At even higher levels, the receiver can be permanently damaged. 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.

Note These distances assume free space path loss and are conservative estimates. Required separation

distances for damage and performance degradation levels in actual deployments are less if conditions are not non-line-of-sight.

OL-24247-01

•

Reduce the configured transmit power to the minimum level.

• Use directional antennas, and keep them away from each other.

• Cable the radios together using a combination of attenuators, combiners, or splitters to achieve a total

attenuation of at least 60 dB.

Installation Guidelines

Caution Under no circumstances should you connect the antenna port from one access point to the antenna port

Chapter 2 Installing the Access Point

For a radiated test bed, the following equation describes the relationships among transmit power, antenna gain, attenuation, and receiver sensitivity:

txpwr + tx gain + rx gain - [attenuation due to antenna spacing] < max rx input level Where: txpwr = Radio transmit power level tx gain = transmitter antenna gain rx gain = receiver antenna gain

For a conducted test bed, the following equation describes the relationships among transmit power, antenna gain, and receiver sensitivity:

txpwr - [attenuation due to coaxial components] < max rx input level

of another access point without using an RF attenuator. If you connect antenna ports, you must not exceed the maximum survivable receive level of 0 dBm. Never exceed 0 dBm, or damage to the access point can occur. Using attenuators, combiners, and splitters having a total of at least 60 dB of attenuation ensures that the receiver is not damaged and that PER performance is not degraded.

Installation Guidelines

Because the access point is a radio device, it is susceptible to common causes of interference that can reduce throughput and range. Follow these basic guidelines to ensure the best possible performance:

• For information on planning and initially configuring your Cisco Mesh network, refer to the Cisco

Wireless Mesh Access Points, Design and Deployment Guide, Release 7.3.

• Review the FCC guidelines for installing and operating outdoor wireless LAN devices at

http://www.cisco.com/en/US/partner/prod/collateral/routers/ps272/data_sheet_c78-647116_ps114 51_Products_Data_Sheet.html.

• Perform a site survey before beginning the installation.

• Install the access point in an area where structures, trees, or hills do not obstruct radio signals to and

from the access point.

• The access points can be installed at any height, but best throughput is achieved when all the access

points are mounted at the same height. We recommend installing the access points no higher than 40 feet to allow support for wireless clients on the ground.

Note To calculate path loss and to determine how far apart to install access points, consult an RF planning

expert.

Site Surveys

2-8

Every network application is a unique installation. Before installing multiple access points, you should perform a site survey to determine the optimum use of networking components and to maximize range, coverage, and network performance.

Consider the following operating and environmental conditions when performing a site survey:

Cisco Aironet 1550 Series Outdoor Mesh Access Point Hardware Installation Guide

OL-24247-01

Chapter 2 Installing the Access Point

• Data rates—Sensitivity and range are inversely proportional to data bit rates. The maximum radio

range is achieved at the lowest workable data rate. A decrease in receiver sensitivity occurs as the radio data increases.

• Antenna type and placement—Proper antenna configuration is a critical factor in maximizing radio

range. As a general rule, range increases in proportion to antenna height. However, do not place the antenna higher than necessary, because the extra height also increases potential interference from other unlicensed radio systems and decreases the wireless coverage from the ground.

• Physical environment—Clear or open areas provide better radio range than closed or filled areas.

• Obstructions—Physical obstructions such as buildings, trees, or hills can hinder performance of

wireless devices. Avoid locating the devices in a location where there is an obstruction between the sending and receiving antennas.

Before Beginning the Installation

Before you begin the installation process:

• Ensure that a site survey has been performed.

Installation Guidelines

• Ensure that your network infrastructure devices are operational and properly configured.

• Ensure that your controllers are connected to switch trunk ports.

• Ensure that your switch is configured with untagged access ports for connecting your access points.

• Ensure that a DHCP server with Option 43 configured is reachable by your access points, or

manually configure the controller information in the access point (for additional information, refer to the “Configuring DHCP Option 43” section on page F-1).

• Become familiar with the access point installation components (see the “Becoming Familiar with

Access Point Installation Components” section on page 2-9).

Becoming Familiar with Access Point Installation Components

The access point is designed to be installed in an outdoor environment, such as the exterior roof overhang of a tall building or a streetlight pole. Carefully review the following figures to become familiar with the system components, connectors, indicators, cables, system interconnection, and grounding:

• Components in a typical access point installation (see Figure 2-1)

• Pole mount installation (see Figure 2-2)

• Cable strand mount installation (see Figure 2-3)

• Streetlight power tap installation (see Figure 2-4)

OL-24247-01

Note The illustrations in this document show all available connections for the access point. Unused

connections are capped with a connector plug to ensure the watertight integrity of the access point, except for the AC power entry connector on the 1552E access point. Liquid-tight adapters are provided for connector openings, which can be installed before or after deploying the access point.

When not using the AC input connector to power the 1552E (for example when powering using the Cisco power injector), it is important to cover the AC power entry connector. The correct cap is Remke part number 75-0086 (http://www.remke.com/).

Note The 1552 access point was designed with consideration for resistance to effects of lightning effects on

the access point electronics. The 1552 access point employs lightning arrestor circuitry on the Ethernet and power ports. On the input Ethernet port, Gas Discharge Tubes (GDT) are used for the Power Entry Module (PEM) to mitigate lightning effect. On the AC power, GDTs are also used along with fuses to mitigate high-current condition. For the DC power, a fuse is used to mitigate high current condition.

While not a common practice, the user may want to consider using lightning protection at the antenna ports for added protection. To meet EN/IEC60950-22 (Clause 4.2) requirements, the installer must ensure that additional protection is provided external to this equipment to reduce transient surges from Overvoltage IV to Overvoltage Category II at the AC power input of the access point. The over-voltage and fault-current protection components used to achieve this protection must comply with the IEC 61643

(CAT5e or better) cable

series of standards. To meet CAN/CSA-C22.2 No. 60950-22-07/UL60950-22 requirements, the installer may use alternative components to provide this additional protection. Those components may comply with ANSI/IEEE C62.11, CSA Certification Notice No. 516, CSA C22.2 No. 1, or UL 1449. Suitability of the components for the application must be determined for the intended installation. (For example, some devices are suitable for installation on the load side of the service entrance only, and some are suitable for use with cord-connected equipment only.)

Mounting the Access Point

Mounting Bracket Assembly on a Pole

The access point can be installed where power is available, without the need for a wired LAN connection. The access point uses intelligent wireless routing that is based on the Adaptive Wireless Path Protocol (AWPP). AWPP enables a remote access point to dynamically optimize the best route to the wired LAN network using another access point.

The 1552 access point uses the 5-GHz radio for the Mesh backhaul and connections. The 2.4-GHz radio is used for local wireless client access.

To mount your access point on a vertical pole or streetlight pole, you need to install two metal bands around the pole to support the access point. This process requires extra tools and material not provided in the pole mount kit (see Tab le 2-2 ).

Safety Precautions

Grounding the Access Point

Warning

Do not locate the antenna near overhead power lines or other electric light or power circuits, or where it can come into contact with such circuits. When installing the antenna, take extreme care not to come into contact with such circuits, as they may cause serious injury or death. For proper installation and grounding of the antenna, please refer to national and local codes (e.g. U.S.: NFPA 70, National Electrical Code, Article 810, Canada: Canadian Electrical Code, Section 54).

Statement 280

For your safety, read and follow these safety precautions.

1. Before you install an antenna, contact your Cisco account representative to explain which mounting

method to use for the size and type of antenna that you are about to install.

2. Select your installation site with safety, as well as performance, in mind. Remember that electric

power lines and phone lines look alike. For your safety, assume that any overhead line can kill you.

3. Contact your electric power company. Tell them your plans and ask them to come look at your

proposed installation.

4. Plan your installation carefully and completely before you begin. Each person involved in an

installation should be assigned to a specific task and should know what to do and when to do it. One person should be in charge of the operation to issue instructions and watch for signs of trouble.

5. When installing your antenna, follow these guidelines:

–

Do not use a metal ladder.

–

Do not work on a wet or windy day.

–

Do dress properly—wear shoes with rubber soles and heels, rubber gloves, and a long-sleeved shirt or jacket.

6. If the assembly starts to drop, move away from it and let it fall. Because the antenna, mast, cable,

and metal guy wires are all excellent conductors of electrical current, even the slightest touch of any of these parts to a power line completes an electrical path through the antenna and the installer.

7. If any part of the antenna system should come in contact with a power line, do not touch it or try to

remove it yourself. Call your local power company to have it removed safely.

8. If an accident should occur with the power lines, call for qualified emergency help immediately.

Grounding the Access Point

The access point must be grounded before connecting power.

Warning

provide grounding for the access point.

In all outdoor installations and when powering the access point with AC power, you must follow these instructions to properly ground the case:

Step 1 If using insulated 6-AWG copper ground wire, strip the insulation as required for the grounding lug. Step 2 Use the appropriate crimping tool to crimp the bare 6-AWG copper ground wire to the supplied

grounding lug (Panduit PLCD6-10A-L).

Note The grounding lug and hardware used must comply with local and national electrical codes.

Step 3 Open the electrical joint compound (supplied), and apply a liberal amount over the metal surface where

the ground strap screw holes are located (see Figure 2-13).

Step 4 Connect the grounding lug to the access point grounding screw holes (see Figure 2-13) using the

supplied two Phillips head screws (M4 x10 mm) with lock washers. Tighten the grounding screw to 22 to 24 in. lbs (2.49 to 2.71 Nm).

Step 5 If necessary, strip the other end of the ground wire, and connect it to a reliable earth ground such as a

grounding rod (see Figure 2-2), an appropriate grounding point on a metal streetlight pole that is grounded (see Figure 2-38), or a grounded cable on a cable strand.
