2 Introduction to the Access Point
The Cisco Aironet 1552S Outdoor Mesh Access Point (hereafter called the access point or AP) is a
ruggedized outdoor access designed for service in mesh networks in hazardous locations. It contains
an ISA100.11a sensor backbone router to communicate with wireless sensors, and the access point
radios provide backhaul service to carry sensor data to your network. The 1552S access point
leverages 802.11n and 802.15.4 technology with integrated radio and internal/external antennas.
The 1552S outdoor platform consists of Multiple Input Multiple Output (MIMO) WLAN radios and
with integrated spectrum intelligence (CleanAir). CleanAir provides full 11n data rates while
detecting, locating, classifying and mitigating radio frequency (RF) interference to provide the best
client experience possible. CleanAir technology on the outdoor 11n platform mitigates WiFi and
non-WiFi interference on 2.4 GHz radios.
The 1552S access point offers multi-band 2.4-GHz and 5-GHz configurations with an option to
configure access and backhaul radios. The radios are called 2.4-GHz MIMO radios and 5-GHz MIMO
radios. The 2.4-GHz radios are used primarily for local access and the 5-GHz radios for both local
access and wireless backhaul in the mesh mode.
The 1552S 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 1552S access point
interoperates with legacy clients and offers enhanced backhaul performance.
The access point is a standalone unit that can be wall 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 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
(WLC), referred to as a controller in this document. The WLC is described in the appropriate Cisco
Wireless LAN Controller Configuration Guide. The Cisco Mesh Networking Solution Deployment
Guide describes how to plan and initially configure the Cisco mesh network, which supports wireless
point-to-multipoint mesh deployments. The controllers use a browser-based management system, a
command-line interface (CLI), or the Cisco Network Control System (NCS) network management
system to manage the controller and the associated access points. The access point is compliant with
Wi-Fi Protected Access 2 (WPA2) and employs hardware-based Advanced Encryption Standard (AES)
encryption between wireless nodes to provide end-to-end security.

Statement 1023
Caution
When the access point is installed outdoors or in a wet or damp location, the AC branch
circuit that is powering the access point should be provided with ground fault protection
(GFCI), as required by Article 210 of the National Electrical Code (NEC).
Note
The liquid-tight adapters must be used on all input/output connections to the access point
where the installation is a non-hazardous location (and conduit is not used). These
liquid-tight adapters are listed in the “Package Contents” section on page 5.
Ethernet (PoE) Ports
The access point supports an Ethernet uplink port and a PoE out port (PoE-Out). The access point
Ethernet uplink port uses an RJ-45 connector (with weatherproofing) to link the access point to the
10BASE-T, 100BASE-T, or 1000BASE-T network. The Ethernet cable is used to send and receive
Ethernet data. The minimum length of this cable must be not less than 10 feet (3 meters).
The access point PoE-Out Ethernet port uses an RJ-45 connector (with weatherproofing) to provide
LAN connectivity and IEEE 802.3af power to a peripheral customer device, such as a camera. The
Ethernet MAC addresses are printed on a label on the bottom of the access point under the LEDs.
14
Tip
The access point senses the Ethernet and power signals and automatically switches internal
circuitry to match the cable connections.
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 small-factor pluggable (SFP) modules:
• 100BASE-BX10-U fiber Rugged SFP module
• 1000BASELX single-mode Rugged SFP module
• 1000BASESX multimode Rugged SFP module
Note
SFP modules are not hot-swappable.
One fiber connection is available on the 1552S access point. The fiber connection is shared through
the same port as the AC or 24 VDC power (shown on Figure 1). Client data is passed to the network
controller through the fiber connection via a fiber-capable switch. For detailed installation
information about the fiber option, see the Cisco Aironet 1550 Series Outdoor Mesh Access Point
Hardware Installation Guide. Configuration information can be found in the controller configuration
guide of the controller you are using.
6 ISA100 Backbone Router and Infrared-based Security
The ISA100.11a standard requires all the devices to be authenticated before joining the network. The
Cisco 1552S access point supports authentication key distribution mechanism to the internal
Backbone Router (BBR) through the Infrared (IR) port. This mechanism is secure, since it requires the
user to be physically located near the device to authenticate it. The key is transmitted to the AP by a
provisioning device, typically a handheld Personal Digital Assistant (PDA) with Windows Mobile 5.0
and IR capability.
The authentication keys are generated and managed by the wireless sensor device manager (WDM).
The PDA is used to upload the authentication keys from the WDM to the Provisioning Device
handheld and to download keys to the BBR using IR media. The keys are encrypted when distributed
15
over the network. Once a key is deployed to a BBR, it is validated by the WDM before the BBR can
join the wireless sensor network. Key deployment is a one-time activity; that is, the devices can rejoin
the network after power down or after any other service interruptions without rekeying the device.
Once the BBR is authenticated, it joins the sensor network. The PDA can be used to monitor the status
of the authenticated device and the handheld displays status such as Discover, Secure, Joined, or Not
Joined. Other BBR parameters can be read and set through the PDA. If the BBR is not joining the
network, its parameter data can be read by the PDA and used to aid in troubleshooting.
Table 1 indicates the status of the BBR using the LEDs in the IR window.

7 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,
16
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 as shown in Figure 6. 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.
The mesh access points can also be configured for point-to-point and point-to-multipoint bridging.
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 6 illustrates a typical mesh configuration using access points.

8 Preparing the Access Point
The access point is a radio device which 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 7.0. This document is
available on cisco.com at
http://www.cisco.com/en/US/docs/wireless/technology/mesh/7.0/design/guide/MeshAP_70.html.
• Do not install the access point in an area where structures, trees, or hills obstruct radio signals to
and from the access point.
18
• You can install the access point at any height, but best throughput is achieved when the access
points are mounted at the same height.
Note
To perform path loss calculation and to determine how far apart to install access points,
consult an RF planning expert.
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/b/g/n operates in an
unlicensed spectrum, there may be sources of interference from other 802.11a wireless devices
(especially in multi-tenant buildings) that could degrade your 802.11 signals. A site survey can
determine if such interference exists at the time of deployment.
A proper site survey involves temporarily setting up mesh links and taking measurements to determine
whether your antenna calculations are accurate. Determine the correct locations and antenna types
before you drill holes and route cables and mounting equipment.
Tip
When power is not readily available during a site survey, use an unrestricted power supply
(UPS) to temporarily power the mesh link.
Consider the following operating and environmental conditions when performing a site survey:
• How far is your wireless link?
• Has a previous site survey been conducted?
• Do you have a clear Fresnel zone between the access points or radio line of sight?
• What is the minimum acceptable data rate within the link?
• Do you have the correct antenna (if more than one antenna is being offered)?
• Do you have access to both of the mesh site locations?
• Do you have the proper permits, if required?
• Are you following the proper safety procedures and practices?
• Have you configured the access points before you go onsite? It is always easier to resolve
configurations or device problems first.
• Do you have the proper tools and equipment to complete your survey?
19
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 radios in a link, you must avoid exceeding the maximum receive input
level of the receiver. At levels higher than the normal the operating range and packet error rate (PER)
performance of the receiver is degraded. At even higher levels, the receiver can be permanently
damaged.
20
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.
• Reduce the configured transmit power to the minimum level.
• Cable the radios together using a combination of attenuators, combiners, or splitters to achieve a
total attenuation of at least 60 dB.
For a radiated test bed, the following equation describes the relationships among transmit power,
antenna gain, attenuation, and receiver sensitivity:
txpwr + tx antenna gain + rx ant 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 RF Attenuator components] < max rx input level
(0 dbm)
Caution
Under no circumstances should you connect the antenna port from one access point to the
antenna port 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

Outdoor Mesh Access Points , which accompanies this guide.
9 Deploying the Access Point
Warning
Do not operate the unit near unshielded blasting caps or in an explosive environment
unless the device has been modified to be especially qualified for such use. Statement 364
The access point is deployed on Layer 3 networks. Layer 3 is the default mode for a newly configured
wireless LAN controller. This guide assumes that you will be deploying your access point on a Layer
3 network and a DHCP server is available.
Before deploying the access point, make sure the controller to which the access point will associate is
properly configured by performing the following operations:
• Make sure that the wireless LAN controller is set to Layer 3 mode
• Verify the wireless LAN controller software version
• Record the access point BVI MAC address
• Enter the access point BVI MAC address to the wireless LAN controller filter list
Verifying the Wireless LAN Controller Mode
Follow these steps to verify that the wireless LAN controller mode is set to Layer 3:
22
Step 1
Open your web-browser and enter the IP address of your wireless LAN controller. Be sure to
precede the IP address with https://. A login screen appears.
Step 2

Step 6
From the menu bar, click MONITOR to return to the Monitor Summary page.
Verifying the Wireless LAN Controller Software Version
On the Summary page, you can verify the software version that the wireless LAN controller is running.
If a version update is necessary, refer to the appropriate controller configuration documentation.
Recording the Access Point MAC Address
Use a text file to record the MAC address of all the access points you intend to deploy in your network.
Having a file of access point MAC addresses will be of considerable value for future testing. While you
are compiling the list, you might want to change the name of the access point to something you can
easily remember. The name can contain up to 32 characters. The following example, fisher_street:ea:co
contains the last four HEX characters of the access point MAC address.
Adding the Access Point MAC Address to the Wireless LAN Controller
Filter List
The wireless LAN controller maintains an access point authorization MAC address list and responds
to discovery requests from access points on that list. To add the access point MAC address (or MAC
addresses) to the Wireless LAN controller filter list, follow these steps:
Step 1
If you are not logged onto the wireless LAN controller, log on now. The Summary page
appears.
Step 2
On the menu bar, click SECURITY. The Security RADIUS Authentication Server page
appears.
Step 3
Under AAA in the left frame, click MAC Filtering. The Security MAC Filtering page appears.
Step 4

Select a WLAN ID or Any WLAN from the WLAN ID pop-up menu.
Step 7
Enter a description (32 characters maximum) of the access point in the Description field.
Step 8
Choose an interface from the Interface Name pop-up menu.
Step 9
Click Apply.
Step 10 Repeat this process to add other access points to the list.
Note
You can also use the controller CLI command config macfilter add to add a MAC
filter entry on the controller.
Step 11 On the menu bar, click Monitor to return to the Monitor Summary page.
Verifying Controller Association
To verify that your access point is associated to the wireless LAN controller, perform these steps:
Step 1
Log into your controller web interface (https) using a web browser.
Step 2
Click Wireless and verify that your access point MAC address is listed under Ethernet MAC.
Step 3
Log out of the controller and close your web browser.
Deployment Notes
Using a DHCP Server in a Layer 3 Mesh Network
To use a DHCP server in a Layer 3 mesh network, make sure the wireless LAN controller is in Layer
3 mode. You must also configure DHCP option 43 on the DHCP server. After the controller is
restarted, the access point receives IP addresses from the DHCP server.
24
Configuring DHCP Option 43
You can use DHCP Option 43 to provide a list of controller IP addresses to the access points, enabling
each access point to find and join a controller. This section contains a DHCP Option 43 configuration
example on a Microsoft Windows 2003 Enterprise DHCP server for use with Cisco Aironet
lightweight access points.
Additional information about Microsoft DHCP Option 43 is available on Cisco.com at the following
URL:
http://www.cisco.com/en/US/tech/tk722/tk809/technologies_configuration_example09186a0080871
4fe.shtml
DHCP Option 43 server implementation information for Cisco IOS is available at cisco.com at the
following URL:
http://www.cisco.com/en/US/docs/wireless/technology/controller/deployment/guide/dep.html#wp106
8287
Note
In DHCP Option 43, you should use the IP address of the controller management interface.
Note
DHCP Option 43 is limited to one access point type per DHCP pool. You must configure a
separate DHCP pool for each access point type.
Cisco Aironet 1000 and 1500 (1505 and 1510) series access points use a comma-separated string
format for DHCP Option 43. Other Cisco Aironet access points use the type-length-value (TLV)
format for DHCP Option 43. DHCP servers must be programmed to return the option based on the
DHCP Vendor Class Identifier (VCI) string (DHCP Option 60) of the access point. The VCI strings for
Cisco access points capable of operating in lightweight mode are listed in Table 2:

Default router is the IP address of the default router, such as 10.0.0.1
DNS Server is the IP address of the DNS server, such as 10.0.10.2
26
Step 3
Add the Option 60 line using the following syntax:
option 60 ascii “VCI string”
For the VCI string, use the value from Table 2. The quotation marks must be included.
Step 4
Add the option 43 line using the following syntax:
option 43 ascii “Comma Separated IP Address List”
For example, if you are configuring Option 43 for Cisco 1000, 1500, or 1550 series access
points using the controller IP addresses 10.126.126.2 and 10.127.127.2, add the following
line to the DHCP pool in the Cisco IOS CLI:
option 43 ascii “10.126.126.2,10.127.127.2”
The quotation marks must be included.
Configuring Option 43 for Cisco 1100, 1130, 1200, 1240, 1250, 1300, 1520, and 1550 Series
Access Points
To configure DHCP Option 43 for Cisco 1100, 1130, 1200, 1240, 1250, 1300, 1520, and 1550 series
access points in the embedded Cisco IOS DHCP server, follow these steps:
Step 1
Enter configuration mode at the Cisco IOS CLI.
Step 2
Create the DHCP pool, including the necessary parameters such as default router and name server.
The commands used to create a DHCP pool are as follows:
ip dhcp pool pool name
network IP Network Netmask
default-router Default router
dns-server DNS Server
Where:
pool name is the name of the DHCP pool, such as AP1550.
IP Network is the network IP address where the controller resides, such as

Step 3
Add the Option 60 line using the following syntax:
option 60 ascii “VCI string”
For the VCI string, use the value from Table 2. The quotation marks must be included.
27
Step 4
Add the option 43 line using the following syntax:
option 43 hex hex string
The hex string is assembled by concatenating the TLV values shown below:
Type + Length + Value
Type is always f1(hex). Length is the number of controller management IP addresses times 4
in hex. Value is the IP address of the controller listed sequentially in hex.
For example, suppose that there are two controllers with management interface IP addresses,
10.126.126.2 and 10.127.127.2. The type is f1(hex). The length is 2 * 4 = 8 = 08 (hex). The
IP addresses translate to 0a7e7e02 and 0a7f7f02. Assembling the string then yields
f1080a7e7e020a7f7f02. The resulting Cisco IOS command added to the DHCP scope is listed
below:
option 43 hex f1080a7e7e020a7f7f02
