5 Configurations
The 700 series access point contains two simultaneous dual-band radios, the 2.4-GHz and 5-GHz
802.11n MIMO radios, in a controller-based mode.
The 700 series access point configuration is AIR-CAP702I-x-K9—two 2.4-GHz/5-GHz dual-band
radios, with integrated dual-band inverted-F antennas
For information on the regulatory domains (shown as “x” in the model numbers) see “Regulatory
Domains” section on page 5.
Internal Antennas
The 702I model access points are configured with up to four dual-band inverted-F antennas and two
2.4-GHz/5-GHz dual-band radios.
There are four antennas deployed inside the access point with one deployed on each corner of the
access point top housing. Each antenna covers both the 2.4 GHz and the 5 GHz bands with a single
feed line. The basic features are as follows:
• Dual-band inverted-F antenna for use in both the 2.4-GHz and 5-GHz bands.
• Antenna unit integrated into 702I model access points.
• Peak gain is approximately 4 dBi in the 2.4-GHz band and approximately 4 dBi in the 5-GHz
band.
Regulatory Domains
The 700 series supports the following regulatory domains (shown as “x” in the model numbers):
• -A, -C, -E, -I, -K, -N, -Q, -R, -S, -T, -Z

7 Configuring the Access Point
This section describes how to connect the access point to a wireless LAN controller. Because the
configuration process takes place on the controller, see the Cisco Wireless LAN Controller
Configuration Guide for additional information. This guide is available on Cisco.com.
The Controller Discovery Process
The access point uses standard Control and Provisioning of Wireless Access Points Protocol
(CAPWAP) to communicate between the controller and other wireless access points on the network.
CAPWAP is a standard, interoperable protocol which enables an access controller to manage a
collection of wireless termination points. The discovery process using CAPWAP is identical to the
Lightweight Access Point Protocol (LWAPP) used with previous Cisco Aironet access points.
LWAPP-enabled access points are compatible with CAPWAP, and conversion to a CAPWAP controller
is seamless. Deployments can combine CAPWAP and LWAPP software on the controllers.
The functionality provided by the controller does not change except for customers who have Layer 2
deployments, which CAPWAP does not support.
In a CAPWAP environment, a wireless access point discovers a controller by using CAPWAP discovery
mechanisms and then sends it a CAPWAP join request. The controller sends the access point a
CAPWAP join response allowing the access point to join the controller. When the access point joins
the controller, the controller manages its configuration, firmware, control transactions, and data
transactions.
Note For additional information about the discovery process and CAPWAP, see the Cisco Wireless
LAN Controller Software Configuration Guide. This document is available on Cisco.com.
Note CAPWAP support is provided in controller software release 5.2 or later. However, your
controller must be running release 7.x.x.x or later to support 700 series access points.

Note You cannot edit or query any access point using the controller CLI if the name of the access
point contains a space.
Note Make sure that the controller is set to the current time. If the controller is set to a time that
has already occurred, the access point might not join the controller because its certificate may
not be valid for that time.
Access points must discovered a controller before they can become an active part of the network. The
access point supports these controller discovery processes:
• Layer 3 CAPWAP discovery—The access point performs a local broadcast (255.255.255.255)
discovery request to find any contollers on the same subnet/vlan. The request can be forwarded to
other networks by the IP helper featuer that is present on switches and router.
• Locally stored controller IP address discovery—If the access point was previously joined to a
controller, the IP addresses of the primary, secondary, and tertiary controllers are stored in the
access point’s non-volatile memory. This process of storing controller IP addresses on an access
point for later deployment is called priming the access point. For more information about priming,
see the “Performing a Pre-Installation Configuration” section on page 10.
• DHCP server discovery—This feature uses DHCP option 43 to provide controller IP addresses to
the access points. Cisco switches support a DHCP server option that is typically used for this
capability. For more information about DHCP option 43, see the “Configuring DHCP Option 43
and DHCP Option 60” section on page 32.
• DNS discovery—The access point can discover controllers through your domain name server
(DNS). For the access point to do so, you must configure your DNS to return controller IP
addresses in response to CISCO-CAPWAP-CONTROLLER.localdomain, where localdomain is
the access point domain name. Configuring the CISCO-CAPWAP-CONTROLLER provides
backwards compatibility in an existing customer deployment. When an access point receives an IP
address and DNS information from a DHCP server, it contacts the DNS to resolve
CISCO-CAPWAP-CONTROLLER.localdomain. When the DNS sends a list of controller IP
addresses, the access point sends discovery requests to the controllers.
Preparing the Access Point
Before you mount and deploy your access point, we recommend that you perform a site survey (or use
the site planning tool) to determine the best location to install your access point.
You should have the following information about your wireless network available:
• Access point locations.
9
Cisco Confidential -- Review Draft
• Access point mounting options: below a suspended ceiling, on a flat horizontal surface, or on a
desktop.
Note You can mount the access point above a suspended ceiling but you must purchase
additional mounting hardware: See “Mounting the Access Point” section on page 13 for
additional information.
• Access point power options: power supplied by the recommended external power supply (Cisco
AIR-PWR-B), a DC power supply, PoE from a network device, or a PoE power injector/hub
(usually located in a wiring closet).
Note Access points mounted in a building’s environmental airspace must be powered using PoE
to comply with safety regulations.
Cisco recommends that you make a site map showing access point locations so that you can record the
device MAC addresses from each location and return them to the person who is planning or managing
your wireless network.
Installation Summary
Installing the access point involves these operations:
• Performing a pre-installation configuration (optional)
• Mounting the access point
• Grounding the access point
• Deploying the access point on the wireless network
Performing a Pre-Installation Configuration
The following procedures ensure that your access point installation and initial operation go as
expected. A pre-installation configuration is also known as priming the access point. This procedure
is optional.
Note Performing a pre-installation configuration is an optional procedure. If your network
controller is properly configured, you can install your access point in its final location and
connect it to the network from there. See the “Deploying the Access Point on the Wireless
Network” section on page 13 for details.

To perform pre-installation configuration, perform the following steps:
Step 1 Make sure that the Cisco wireless LAN controller DS port is connected to the network. Use
the CLI, web-browser interface, or Cisco Prime Infrastructure procedures as described in the
appropriate Cisco wireless LAN controller guide.
a. Make sure that access points have Layer 3 connectivity to the Cisco wireless LAN controller
Management.
b. Configure the switch to which your access point is attach to. See the Cisco Unified Wireless
Network WLAN Controller Guide: Cisco 5500 Series WLAN Controllers for additional
information.
c. Set the Cisco wireless LAN controller as the master so that new access points always join with
it.
