The Access Point AIR-AP1852I-E-K9 of the Cisco 1852i series is a good choice for small to medium size networks. AIR-AP1852I-E-K9 supports 4 x 4 MIMO with three spatial streams for single users and three spatial streams for multi-users. It delivers 802.11 ac beam forcing transmission. It also provides an internal Antenna with 1 x 10/100/1000 BASE-T auto-sensing with RJ-45 and Power of Ethernet (PoE). Also, AUX for link Aggression, Management console port via RJ-45, and USB port for future software. Quick SpecsProduct CodeAIR-AP1852I-E-K9Description802.11ac Wave 2 Access Point, 4×4:4, Internal-Ant, E Regulatory DomainFeatures- 4×4 MIMO with four spatial streams, single-user MIMO- 4×4 MIMO with three spatial streams, multiuser MIMO- MRC- 802.11ac beamforming (transmit beamforming)- 20-, 40-, and 80-MHz channels- PHY data rates up to 1.7 Gbps (80 MHz in 5 GHz)- Packet aggregation: A-MPDU (Tx/Rx), A-MSDU (Tx/Rx)- 802.11 DFS- CSD supportRegulatory DomainE (E regulatory domain):- 2.412 to 2.472 GHz; 3 channels- 5.180 to 5.320 GHz; 8 channels- 5.500 to 5.700 GHz; 8 channels(Excludes 5.600 to 5.640 GHz)AntennaInternal AntennaInterfaces- 1 x 10/100/1000BASE-T autosensing (RJ-45), Power over Ethernet (PoE)- 1 x 10/100/1000BASE-T autosensing (RJ-45), AUX (used for Link Aggregation)- Management console port (RJ-45)- USB 2.0 (enabled via future software)Dimensions (W x L x H)8.3 x 8.3 x 2 in.
