Description

The Aironet 1850 is an indoor, controller-based dual-band access point for enterprise deployments such as offices, where appearance matters. This AP1852I model uses four integrated dual-band antennas tucked under the top housing, and it is built for the Z regulatory domain.

It supports 802.11a/b/g/n/ac Wave 2 on both 2.4 GHz and 5 GHz with 4x4 MIMO and four spatial streams. The 5 GHz radio supports downlink MU-MIMO with data rates up to 1,733 Mbps, while the 2.4 GHz radio runs 802.11n at up to 216 Mbps. Wired connectivity is two 10/100/1000BASE-T RJ-45 ports, one carrying PoE input and the second AUX port used for link aggregation, plus an RJ-45 console port. It carries 1 GB DRAM and 256 MB flash, and brochure figures list support for up to 400 clients.

This SKU runs the CAPWAP software image and joins a Cisco wireless LAN controller; the K9C variant is the separate Mobility Express version. It is powered by 802.3at PoE+ for full function, or by the AIR-PWRINJ4 injector or AIR-PWR-C local power supply. It works with Cisco controllers running AireOS or the Catalyst 9800 series.

FAQs

Q: Does this access point need a wireless LAN controller?
A: Yes. This SKU runs the controller-based CAPWAP image and joins a Cisco wireless LAN controller running AireOS or the Catalyst 9800 series. The K9C variant is the separate Mobility Express version.

Q: How is it powered?
A: It runs fully on 802.3at PoE+ (19.93 W budget), the AIR-PWRINJ4 30 W injector or the AIR-PWR-C local power supply. Input is 44 to 57 VDC.

Q: What happens on 802.3af PoE?
A: On 802.3af with the AIR-PWRINJ5 injector, the budget is 12.95 W. The radios keep full function, but the AUX and USB ports are disabled.

Q: What does the AUX port do?
A: The second 10/100/1000BASE-T RJ-45 port is used for link aggregation alongside the primary PoE port.

Q: How does the Z regulatory domain model differ from other AP1852I SKUs?
A: The AP1852I is the internal-antenna model, and the Z suffix sets the Z regulatory domain. The external-antenna 1852E is the separate model aimed at harsher environments.
