5 Configurations
The 3700 series access point contains two simultaneous dual-band radios, the 2.4-GHz MIMO radio
and the 5-GHz 802.11ac MIMO radio. The 3700 series access point configurations are:
•AIR-CAP3702E-x-K9—two 2.4-GHz/5-GHz dual-band radios, up to 4 external dual-band
diopole antennas
•AIR-CAP3702I-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 7.
External Antennas
The 3702E model is configured with up to four external dual-band dipole antennas, and two 2.4-GHz/
5-GHz dual-band radios. The radio and antennas support frequency bands 2400–2500 MHz and
5180–5865 MHz through a common dual-band RF interface. Features of the external dual-band
dipole antennas are:
•Four RTNC antenna connectors on the top of the access point
•Four TX/RX antennas
These antennas are supported on the 3702E:
•AIR-ANT2524DB-R
•AIR-ANT2524DW-R

Internal Antennas
The 3702I model access point is configured with 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
3702I 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 the 3702I model access point.
•Peak gain is approximately 4 dBi in both the 2.4-GHz and 5-GHz bands.

6 Access Point Ports and Connectors
The 3702E model access point has external antenna connectors and the LED indictor on the top of the
model, as shown in Figure 1. The 3702I model access point has integrated antennas and does not have
external connectors on the top of the unit; however, it does have the LED indicator on top of the unit,
as shown in Figure 2.

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 7.6.0.0 or later to support 3700 series access points.
