Cisco Aironet 1542I Outdoor 802.11ac Wave 2 Access Point, Domain E

Cisco lists the AIR-AP1542I-E-K9 as the Aironet 1542I for regulatory domain E, a dual-band 802.11a/g/n/ac Wave 2 outdoor access point with 2x2 MIMO and two spatial streams, supporting MU-MIMO and single-user MIMO. Cisco gives up to 867 Mbps PHY on 5 GHz at 80 MHz and up to 1.1 Gbps across both radios.

Domain E covers 2.412 to 2.472 GHz (13 channels) on 2.4 GHz, and 5.500 to 5.580 GHz (5 channels) plus 5.660 to 5.700 GHz (3 channels) on 5 GHz. The integrated dual-band radome antenna is vertically polarized and omnidirectional, at 5 dBi on both bands. Maximum conducted transmit power is 27 dBm at 2.4 GHz and 25 dBm at 5 GHz.

A 10/100/1000BASE-T autosensing RJ-45 port takes PoE in, and an RJ-45 management console port, a multicolor LED and a reset button are on the unit. Power is 802.3af or 802.3at PoE, with a maximum draw of 13.9 W over 100 m of Category 5 cable. Uplink is by Ethernet or wireless mesh.

The housing is IP67 under IEC 60529 and measures 7.9 x 5.9 x 2.4 in (20 x 15 x 6.1 cm). Operating temperature is -40 to 65 C ambient without solar loading and -40 to 55 C with it; storage is -40 to 85 C. Cisco rates wind resistance at 100 mph sustained and 165 mph gusts.

The AIR-AP1542D has the same radio, port, power and environmental figures but uses a directional dual-polarization antenna of 8 dBi at 2.4 GHz and 9 dBi at 5 GHz, mounted horizontally for omni coverage or vertically for semi-omni coverage.

More Wi-Fi hardware is on the Cisco wireless page, including the MR76-HW Wi-Fi 6 access point with external antennas.
