1 About this Guide

This guide provides instructions on how to install your Cisco Aironet 2800I and 2800E series access

points and provides links to resources which can help you configure the access point. This guide

provides mounting instructions and limited troubleshooting procedures.

The 2800 series access point is referred to as access point or AP in this document.

2 About the Access Point

The Cisco Aironet 2800 Series Wi-Fi access points provide 802.11ac Wave 2 with Multi User MIMO

(MU MIMO). This AP series offers dual-band radios (2.4 GHz and 5 GHz) with integrated and

external antenna options. The series supports high-performing Spectrum Intelligence which sustains

three spatial stream rates over a deployable distance with high reliability when serving clients. The

access points support full inter-interoperability with leading 802.11ac clients, and support a mixed

deployment with other access points and controllers.

A full listing of the access point's features and specification are provided in the Cisco Aironet 2800

Series Access Point Data Sheet, at the following URL:

(URL will be added when available, before FCS)

Access Point Features

The 2800 series access point is a wireless controller-based product and supports:

• Simultaneous dual-band (2.4-GHz and 5-GHz) radios

• Integrated antennas on the 2802I access point model (AIR-AP2802I-x-K9)

• External antennas on the 2802E access point models (AIR-AP2802E-x-K9)

Note The ‘x’ in the model numbers represents the regulatory domain. For information on

supported regulatory domains, see the“AP Model Numbers and Regulatory Domains”

section on page 4.

The other features of the 2800 series APs are:

• Multi-Gigabit Ethernet (mGig) Support, providing multiple gigabit uplink speeds of 2.5G and 5G

in addition to 100M and 1G speeds.

• Radio Role Flexibility, allowing for either manual configuration or for the APs to intelligently

determine the operating role of the integrated radios based on the available RF environment. The

AP can operate in the following modes:

–

2.4GHz and 5GHz role, where one radio serves clients in 2.4GHz mode, while the other serves

clients in 5GHz mode.

–

Dual 5GHz role, with both radios operating in the 5GHz band, actively serving client devices

to maximize the benefits of 802.11ac wave 2 and to increase client device capacity.

–

Wireless Security Monitoring and 5GHz role, where one radio serves 5GHz clients, while the

other radio scans both 2.4GHz and 5GHz for wIPS attackers, CleanAir interferers, and rogue

devices.

• Cross-AP Noise Reduction, a Cisco innovation that enables APs to intelligently collaborate in real

time about RF conditions so that users connect with optimized signal quality and performance.

• Optimized AP Roaming for ensuring that client devices associate with the AP in their coverage

range that offers the fastest data rate available.

• Cisco ClientLink 3.0 technology for improved downlink performance to all mobile devices,

including one-, two-, and three-spatial-stream devices up to 802.11ac Wave 1 and Wave 2. The

technology also improves battery life on mobile devices.

• Cisco CleanAir technology enhanced with 160MHz channel support. CleanAir delivers proactive,

high-speed spectrum intelligence across 20-, 40-, and 80-, and 160-MHz-wide channels to combat

performance problems arising from wireless interference.

• MIMO equalization capabilities, which optimize uplink performance and reliability by reducing

the impact of signal fade.

You need to verify whether the AP model you have is approved for use in your country. To verify

approval and to identify the regulatory domain that corresponds to a particular country, visit

http://www.cisco.com/go/aironet/compliance. Not all regulatory domains have been approved. As and

when they are approved, this compliance list will be updated.

Antennas and Radios

The 2800 series access point contains two simultaneous dual-band radios, the 2.4GHz and 5GHz

MU-MIMO radio, and the 5-GHz 802.11ac MU-MIMO radio. The 2800 series access point

configurations are:

• AIR-CAP2802I-x-K9—two 2.4-GHz/5-GHz dual-band radios, with integrated dual-band

inverted-F antennas.

• AIR-AP2802E-x-K9—two 2.4-GHz/5-GHz dual-band radios, up to 4 external dual-band dipole

antennas.

Internal Antennas

The 2802I 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

2802I 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 2802I model access point.

• Peak gain is approximately 4 dBi in both the 2.4-GHz and 5-GHz bands.

External Antennas

The 2802E 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
