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 integrated and external antenna options, with a dedicated 5 GHz

radio and a flexible radio that can be configured as a 2.4 GHz radio (default) or as an additional

5 GHz radio. This access point supports a greater overall High Density Experience (HDX) which

provides mission-critical wireless to meet your performance needs. The access points support full

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 specifications are provided in the Cisco Aironet 2800

Series Access Point Data Sheet, at the following URL:

Access Point Features

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

•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.

•Flexible Radio Assignment, 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:

–

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

serves clients in 5 GHz mode.

–

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

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

–

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

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

rogue devices.

•Multiuser Multiple-Input Multiple-Output (MU-MIMO) technology with 3 spatial streams.

•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 4.0 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.

The AP supports the following operating modes:

•Centralized

•Sniffer

•FlexConnect

•Monitor Mode

•Service Provider Option 60 (DHCP Option 60)

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 a dedicated 5 GHz radio and a flexible radio that can be

configured as a 2.4 GHz radio (default) or as an additional 5 GHz radio. The 2800 series access point

configurations are:

•AIR-AP2802I-x-K9—One 2.4 GHz/5 GHz flexible radio and one 5 GHz radio.

•AIR-AP2802E-x-K9—One 2.4 GHz/5 GHz flexible radio and one 5 GHz radio. The are 4

dual-band dipole and a Smart antenna connector.

Internal Antennas

The 2802I has 12 cross polarized internal antennas.

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

•Smart Antenna connector for connecting an external antenna

Supported External Antennas

Cisco also provides the following external antenna accessories:

•5 ft Low Loss RF cable with RP-TNC and N-type Connectors (AIR-CAB005LL-R-N/=). You will

need four of these.

•2 ft Smart Antenna Connector to RP-TNC Connectors (AIR-CAB002-DART-R=).
