Cisco Aironet 1850 Series End-of-Life & EOSL Dates

SUPPORT ENDING SOONCisco support ends April 2027.

The Aironet 1850 is an 802.11ac Wave 2 access point with a 4x4 radio driving four spatial streams, rated to 1.7 Gbps on the 5 GHz radio and 2.0 Gbps aggregate across both bands, with multi-user MIMO serving several Wave 2 clients at once. Cisco aimed it at small and mid-sized enterprise networks.

The 1852i model carries internal omni antennas and the 1852e takes external antennas for harder RF environments. A Gigabit PoE uplink pairs with an auxiliary Gigabit port for link aggregation, power comes from 802.3at or 802.3af with reduced radio chains on the lower budget, and it runs controller-less under Mobility Express or joins AireOS and Catalyst 9800 controllers.

The Cisco Aironet 1850 Series is a wireless access point in Cisco's Aironet product line. End-of-sale and end-of-service-life dates are listed by part number below, each linked to the Cisco EOL bulletin.

Cisco Aironet 1850 Series is still under Cisco support, to Apr 2027. Fold the eventual replacement into your planning cycle. Cisco’s named migration path: Cisco Catalyst 9115AX Series Access Points.

Support Runway Score40/100 · Action recommended
Why this score
  • End of service life within 6 months
  • Vendor-published date, source-linked
  • Vendor-named replacement / migration path available
  • Category: wireless access point

Support-lifecycle timing and source confidence only. Higher means more runway. It is not a risk, safety or compliance rating. How it is calculated

Figure 1. Support runs to Apr 2027. Budget a refresh or line up cover before that date.
Figure 2. The 1850 Series against 4 other models in Cisco Aironet. Each bar runs from the earliest milestone Cisco publishes for that model, which is first availability where it gives one and end of sale otherwise, to its last date of support. The vertical rule is today; bars entirely to its left are past support.

Options from here

Cisco support for the Cisco Aironet 1850 Series ends soon. Weigh these before the cutoff:

Schedule migration

Support ends soon. Set the replacement window now, not mid-outage.

Line up third-party maintenance

Bridge coverage past the OEM cutoff if you can't migrate in time.

Budget the refresh

Get the replacement into this planning cycle.

Pre-stock spares

Secure spares before they get scarce after end-of-sale. Current eBay listings for Aironet 1850 Series ↗

Independent and informational. EOSL.ai sells no hardware and no maintenance, and lists no paid placements. Third-party maintenance keeps unsupported gear in production past the OEM cutoff; whether it fits depends on the role the asset plays.
