Cisco Aironet 1850 Access Point delivers industry-leading performance with enterprise-class 4×4 MIMO, four-space streaming access points that support IEEE’s new 802.11ac Wave 2 специфікація, making it ideal for small to medium-sized networks in the enterprise and service provider markets. The Aironet 1850 Series expands support to support next-generation Wi-Fi clients such as smartphones, tablets and high-performance laptops with integrated 802.11ac Wave 1 or Wave 2 підтримка.
Cisco Aironet 1850 Access Point General Introduction
Cisco 1850 має 4 different models:
AIR-AP1852I-x-K9: Dual-band, controller-based 802.11a/g/n/ac, Wave 2
AIR-AP1852I-x-K9C: Dual-band, controller-based 802.11a/g/n/ac, Wave 2, configurable
AIR-AP1852E-x-K9: Dual-band, controller-based 802.11a/g/n/ac, Wave 2
AIR-AP1852E-x-K9C: Dual-band, controller-based 802.11a/g/n/ac, Wave 2, configurable
Cisco Aironet 1850 Access Point provides the data rate of more than 1.7 Gbps on the 5-GHz radio, more than triple the rates offered by today’s high-end 802.11n access points. It also enables total aggregate dual-radio data rate of 2.0 Гбіт/с, and provide the necessary foundation for enterprise and service provider networks to stay ahead of the performance and bandwidth expectations and needs of their wireless users.

Cisco Aironet 1850 Access Point Feature
1 ，802.11ac Wave 2 access point supporting 4×4 Multiple Input Multiple Output (MIMO) технології: four spatial streams when running in single-user MIMO mode and three spatial streams when running in multi-user MIMO mode; The data rate is 1.7 Гбіт/с, ensuring greater capacity and reliability than competing access points.
2， Multi-user MIMO: Allows simultaneous transfer of data to multiple clients supporting 802.11ac Wave 2 to enhance the client experience. Prior to the introduction of multi-user MIMO, 802.11n and 802.11ac Wave 1 access points could only transmit data to one client at a time, so they are often referred to as single-user MIMO.
3， Transmission beamforming technology: Improves downlink performance of mobile devices (including one spatial stream, two spatial streams, and three spatial stream devices on 802.11ac) while extending the reach of mobile devices such as smartphones and tablets Battery Life.
