AIR-AP1852E-Q-K9C Cisco Aironet 1852e Indoor Dual-band 4x4 MIMO AP

AIR-AP1852E-Q-K9C Q-Domain Mobility Express AP

AIR-AP1852E-Q-K9C combines the external-antenna Aironet 1852e hardware, Q regulatory domain and factory Mobility Express image. Cisco's Japanese antenna record lists this exact PID and identifies Q models for domestic W56-band use; it must not be substituted with the AIR-AP1852E-N-K9C regulatory version.

External antenna evidence

The AP has no integrated service antenna set. Record four approved dual-band antenna paths, connector condition, cable loss, mount position and gain. Cisco's Japan table names AIR-ANT2524DB-R for this exact Q PID, but deployment approval still depends on the installed antenna and local rules.

Power and network acceptance

Test both Gigabit Ethernet interfaces, PoE negotiation, radio status and controller election. Under 802.3af, Cisco reduces the 2.4 GHz radio from 3x4 to 2x3 and disables AUX/USB; preserve the power-source result with the inventory.

Retired platform planning

Save the Mobility Express image, country configuration, primary role and recovery backup. Cisco ended sale on October 31, 2022 and lists April 30, 2027 as last support, with Catalyst 9115AX as the migration family.

Official evidence: Cisco exact Q K9C lifecycle row, Cisco model and K9C image guide, Cisco 1852e radio and power specifications, Cisco Japan exact Q PID antenna table and Cisco regulatory approval lookup.
