The AIR-CAP3702I-A-K9 is a Cisco Aironet 3702i access point, a controller-based dual-band 802.11a/g/n/ac model with internal antennas for indoor environments, in the A regulatory domain. The 3702i belongs to the Aironet 3700 Series, which adds 802.11ac Wave 1 on the integrated 5 GHz radio and keeps 802.11n at 2.4 GHz.
The radios are 4x4 MIMO with three spatial streams. 802.11ac speeds reach 1.3 Gbps on 80 MHz channels in the 5 GHz band, and 802.11n reaches 450 Mbps on 40 MHz channels. Maximum transmit power is 23 dBm with four antennas in both bands, adjustable by channel and country. The internal omni antennas have 4 dBi gain at 2.4 GHz and 6 dBi at 5 GHz.
The unit has one 10/100/1000BASE-T autosensing RJ-45 port and an RJ-45 console port, with 512 MB of DRAM and 64 MB of flash. It measures 8.7 x 8.7 x 2.11 in (22.1 x 22.1 x 5.4 cm) without the mounting bracket and weighs 2.5 lb (1.13 kg). At the switch or injector it draws 16.1 W when running 4x4:3 on PoE+, and 15.4 W when 802.3af PoE limits the radios to 3x3:3.
The 3702i needs Cisco Unified Wireless Network Software Release 7.6 or later on a controller. Supported controllers include the Cisco 2500, 5500, Flex 7500 and 8500 Series, the Wireless Controller Module for ISR G2, the Wireless Services Module 2 for Catalyst 6500 switches and the Virtual Wireless Controller. The AIR-CT5508-50-K9 Cisco 5508 wireless controller is one of those controller families, and an 802.11ac Wave 1 external-antenna model from the Aironet 2700 Series is the AIR-CAP2702E-A-K9 Aironet 2702e access point.
