Cisco Aironet 3802I wireless access point

The Cisco Aironet 3802I is a wireless access point built for commercial environments that require 802.11ac connectivity. It supports dual-band operation at 2.40 GHz and 5 GHz with a 4x4:3 spatial-stream configuration. This unit suits businesses deploying high-density Wi-Fi across offices, campuses or retail spaces.

Thermals noise and power draw

The access point is designed for indoor ceiling or wall mounting with passive cooling, so it operates silently in normal use.
