AIR-CAP3502I-A-K9 Cisco Aironet 3502i Access Point

The AIR-CAP3502I-A-K9 is a Cisco Aironet 3502i access point: a controller-based dual-band 802.11a/g/n model with internal antennas for indoor environments, in the A regulatory domain. The 3500 Series also has a single-band 3501i and, with external antennas, the 3502e.

The radios use 2x3 MIMO with two spatial streams and reach 300 Mbps in 802.11n, with 20 and 40 MHz channels, maximal ratio combining and A-MPDU and A-MSDU packet aggregation. Maximum transmit power in the 2.4 GHz band is 23 dBm for 802.11b and 20 dBm for 802.11g and 802.11n, and 20 dBm at 5 GHz, each with two antennas. The A domain covers 11 channels at 2.4 GHz and 8, 8 and 5 channels in the 5 GHz sub-bands.

The access point has one 10/100/1000BASE-T autosensing RJ-45 port and an RJ-45 console port, with 128 MB of DRAM and 32 MB of flash. It measures 8.7 x 8.7 x 1.84 in (22.1 x 22.1 x 4.7 cm) without the mounting bracket and weighs 2.3 lb (1.04 kg). Power draw is 12.95 W, from an 802.3af Ethernet switch, an AIR-PWRINJ4= power injector or an AIR-PWR-B= local power supply, and the draw rises to 15.4 W once cable losses of up to 2.45 W are added.

Cisco Unified Wireless Network Software Release 7.0 or later is needed on the controller. 802.11ac Aironet models include the AIR-CAP2702E-A-K9 Aironet 2702e or the AIR-CAP2702I-E-K9 Aironet 2702i, and all models are in Cisco wireless.
