Aironet 3802I at a glance

Radios: a dedicated 5 GHz radio plus a flexible radio that runs at either 2.4 GHz or 5 GHz, so the access point can operate in dual 5 GHz mode with both radios on the 5 GHz band.
Wi-Fi: 802.11ac Wave 2 with 4x4 MU-MIMO and three spatial streams, up to 2.6 Gbps per radio.
Antennas: internal. The "i" in 3802i marks the internal-antenna model for indoor ceilings. Cisco's 3802e uses external antennas, and only the 3802e and 3802p have the smart antenna connector.
Wired connections: two Ethernet ports, with a 100/1000/2500/5000 Multigigabit Ethernet RJ45 interface that Cisco rates for Cat 5e cabling.
Power: 802.3at PoE+ or Cisco UPOE. Cisco lists 25.8 W at the switch port with every feature enabled except the USB 2.0 port.

What does the -B in the part number mean?

The letter after 3802I is the regulatory domain. The B domain sets which 2.4 GHz and 5 GHz channels the radios use. Cisco asks buyers to confirm the domain is approved for the country where the access point will be installed, so match it to the units already on your network.

Does the AIR-AP3802I-B-K9 need a wireless controller?

Cisco lists this part number as a controller-based access point. Cisco also documents Mobility Express for the 3800 Series, which lets the access points run on a network without a physical controller.

Can a PoE+ switch power it?

Yes. An 802.3at PoE+ port runs the 3802I with all features on except USB. A Cisco UPOE port, an 802.3at power injector or Cisco's 50 W power supply are the other options Cisco lists.
