Cisco Aironet 1850 Series
Product overview
Ideal for small and medium-sized networks, the Cisco® Aironet® 1850 Series delivers industry-leading
performance for enterprise and service provider markets via enterprise-class 4x4 MIMO, four-spatial-stream
access points that support the IEEE’s new 802.11ac Wave 2 specification. The Aironet 1850 Series extends
support to a new generation of Wi-Fi clients, such as smartphones, tablets, and high-performance laptops that
have integrated 802.11ac Wave 1 or Wave 2 support.
Features and benefits
With 802.11ac Wave 2, the Aironet 1850 Series provides a data rate of up to 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 a total aggregate
dual-radio data rate of 2.0 Gbps, providing the necessary foundation for enterprise and service provider
networks to stay ahead of the performance and bandwidth expectations and needs of their wireless users.
Due to its convenience, wireless access is increasingly the preferred form of network connectivity for corporate
users. Along with this shift, there is an expectation that wireless should not slow down users’ day-to-day work,
but should enable a high-performance experience while allowing users to move freely. The 1850 Series
delivers industry-leading performance for highly secure and reliable wireless connections and provides a robust
mobility experience that includes:
●
802.11ac Wave 2 with 4x4 Multiple-Input Multiple-Output (MIMO) technology with four spatial streams
when operating in single-user MIMO mode and three spatial streams while operating in multiuser MIMO
mode, offering 1.7-Gbps rates for more capacity and reliability than competing access points.
●
Multiuser MIMO, allowing transmission of data to multiple 802.11ac Wave 2 capable clients
simultaneously to improve client experience. Prior to multiuser MIMO, 802.11n and 802.11ac Wave 1
access points could transmit data to only one client at a time, typically referred to as single-user MIMO.
●
Transmit beamforming technology to improve downlink performance to mobile devices, including one-,
two-, and three-spatial-stream devices on 802.11ac, while improving battery life on mobile devices
such as smartphones and tablets.
●
Flexible deployment mode through Cisco Mobility Express is ideal for small to medium-sized
deployments that require multiple access points. Easy setup allows the 1850 Series to be deployed on
networks without a physical controller.
●
Secure connections for remote workers or the micro-office. Any Cisco Aironet or Catalyst access point
can function as an OfficeExtend Access Point (OEAP). With an OEAP, an employee at home or in a

●
Cisco User Defined Network, a feature available in Cisco DNA Center, that allows IT to give end users
control of their very own wireless network partition on a shared network. End users can then remotely
and securely deploy their devices on this network. Perfect for university dormitories or extended hospital
stays, Cisco User Defined Network grants both device security and control, allowing each user to choose
who can connect to their network. (Available second half of calendar year 2020.)
●
The Wi-Fi 6 readiness dashboard, a new dashboard in the Assurance menu of Cisco DNA Center. It will
look through the inventory of all devices on the network and verify device, software, and client
compatibility with the new Wi-Fi 6 standard. After upgrading, advanced wireless analytics will indicate
performance and capacity gains as a result of the Wi-Fi 6 deployment. This is an incredible tool that will
help your team define where and how the wireless network should be upgraded. It will also give you
insights into the access point distribution by protocol (802.11 ac/n/abg), wireless airtime efficiency by
protocol, and granular performance metrics.
All of these features help ensure the best possible end-user experience on the wireless network. Cisco also
offers the industry’s broadest selection of 802.11n and 802.11ac antennas, delivering optimal coverage for a
variety of deployment scenarios.
The Cisco Aironet 1850 Series Access Points also support:
●
The Onyx BLE Beacon Solution, which provides a feature that the Aironet access points are missing:
built-in Bluetooth Low Energy (BLE). The Onyx BLE Beacons work smoothly with indoor location-based
services. Used for indoor navigation, proximity marketing, and asset tracking, BLE is a tool that is
becoming more and more useful with each passing day. With the Onyx BLE Beacons, customers can add
BLE to their networks.
