AIR-CAP3702I-H-K9 Cisco Aironet 3700i Access Point

AIR-CAP3702I-H-K9 Integrated-Antenna H-Domain AP

AIR-CAP3702I-H-K9 is the H-domain Aironet 3702I for controller-managed indoor Wi-Fi. Its four integrated dual-band antennas, 4x4 MIMO radio with three spatial streams, 5 GHz 802.11ac support and CleanAir are built around office-style ceiling or wall deployment.

Integrated antenna is a fixed physical boundary

Cisco documents four internal dual-band inverted-F antennas with approximately 4 dBi peak gain in each band. The I model has no external antenna connectors, so coverage changes require placement, orientation and RF-design changes rather than attaching an external antenna. Use AIR-CAP3702E-C-K9 only when the design and approved C-domain identity specifically require that different chassis.

H-domain receiving control

Verify the H suffix on the chassis and packaging, then confirm that the intended country currently permits that domain through Cisco's compliance lookup. Preserve the controller country code, legal channel set and transmit-power result as deployment evidence. A different domain cannot be converted by relabeling or controller configuration alone.

WLC join and installation checks

This AIR-CAP PID is controller based. Test Ethernet and PoE, compatible controller software, AP image, certificate state, CAPWAP join, both radios and CleanAir reporting. Inspect the enclosure and mounting bracket because antenna orientation follows the installed chassis; external antennas and RF cables are not part of this model.

Lifecycle and replacement context

The Aironet 3700 series reached end of sale on 30 April 2019 and last support on 30 April 2024. Cisco identifies AIR-AP3802I-H-K9 as the historical H-domain replacement for this exact integrated-antenna PID. Do not treat that historical mapping as proof of current support without checking the replacement's own lifecycle and the target controller architecture.
