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
