Models
The Cisco 2800 and 3800 Series Access Points target customers requiring support for mission-critical and
best in class applications. The 2800/3800 embodies ClientLink 4.0, an innovative antenna technology comprising
four transmit radios and four receive radios called 4x4 in a Multiple Input Multiple Output (MIMO)
configuration and supporting three spatial streams (3SS), together referenced as 4x4:3. Using this type of
antenna system along with additional Modulation Coding Scheme (MCS) rates supporting up to 256 QAM
and up to 160 MHz channel bonding, rates of up to 5 Gbps can be supported.

ClientLink 4.0 uses these features along with an additional antenna (N+1) to allow for beam-forming for all
802.11a/g/n/ac and now ac Wave-2 clients including those supporting 3 spatial streams.
Figure 1: Access Point Portfolio Placement
Access points are available in three models:
•Internal antennas version labeled “i”that has captured antennas (part of the housing and not removable).
The “i”series is designed for indoor Enterprise installations where office aesthetics are a primary concern.
•External antennas version labeled “e”that is more rugged and designed for industrial use in locations
such as hospitals, factories, and warehouses, anywhere a need exists for external antennas and/or extended
operating temperatures. The “e”version also supports mounting inside NEMA enclosures for use in the
most demanding environments.
•Access points for professional install are labeled “p”series and may be used in outdoor applications.

Supported Code Versions Compatible with AP 2800 and AP 3800
The minimum versions supporting the AP 2800 and 3800 are:
•Wireless LAN Controller (WLC) AirOS release 8.2MR1
•Polaris release 16.3
•Prime release 3.1MR1
•MSE or CMX 10.2.2
•ISE 2.0
Differences between the AP 2800 and AP 3800 Access Points
The mechanical front of the AP 2800 and AP 3800 are nearly identical in physical appearance.

Supported Code Versions Compatible with AP 2800 and AP 3800
The AP 3800 is also available in a "P" version. The external antenna "E" versions permit antenna gains up to
6 dBi, "P" version up to 13 dBi.
Figure 3: AP 2800/3800
There are slight differences in the weight and thickness of the 2800 and 3800. The AP 3800 is a bit more
robust as it has support for mGig (NBASE-T) and optional module support. AP 2800 on left is smooth and
does not have heat fins.
