Cisco AIR-AP1852I-Z-K9 Aironet 1852 802.11ac Wave 2 Dual Band WiFi AP PoE Wty

Cisco Aironet 1852I — 802.11ac Wave 2 Dual-Band Enterprise Access Point The Cisco Aironet 1852I (AIR-AP1852I-Z-K9) is a high-density 802.11ac Wave 2 enterprise access point delivering 4×4 MIMO on 5 GHz (up to 1.3 Gbps) and 3×3 MIMO on 2.4 GHz (up to 450 Mbps) through integrated internal antennas. Designed for large offices, campuses, and education environments, it supports both controller-based (Cisco WLC / Catalyst Center) and standalone Mobility Express deployments. This unit ships with a 12-month Reboot IT warranty and is professionally tested at our Melbourne facility. Key Benefits 802.11ac Wave 2 MU-MIMO: 5 GHz 4×4 MIMO with multi-user MIMO transmits simultaneously to multiple Wave 2 clients — doubles effective capacity in high-density environments. Aggregate 1.7 Gbps throughput: 1.3 Gbps on 5 GHz plus 450 Mbps on 2.4 GHz in dual-band concurrent operation across a single radio unit. Single-cable PoE deployment: IEEE 802.3at (PoE+) powered — one cable carries both data and power, no separate outlet or injector required for full-power operation. Mobility Express mode: Runs an embedded virtual WLC supporting up to 25 APs, enabling small-site deployments without dedicated Cisco WLC hardware. CleanAir spectrum intelligence: Identifies and classifies RF interference sources (Bluetooth, video cameras, microwave ovens) to automatically mitigate channel conflicts. 12-month Reboot IT warranty: Professionally inspected, tested, and graded at our Melbourne facility — Australian warranty and support since 2001. Performance in Use The 1852I was engineered for high-density wireless environments where legacy 802.11n APs create throughput bottlenecks. Its Wave 2 MU-MIMO capability allows simultaneous data transmission to up to three 802.11ac Wave 2 clients at once — a meaningful improvement in classrooms, conference centres, and open-plan offices where dozens of devices connect concurrently. BandSelect steers capable dual-band clients to the cleaner 5 GHz band, reducing congestion on 2.4 GHz while ClientLink beamforming focuses signal energy toward individual clients to improve edge-of-range performance. In a Cisco Unified Wireless environment, the AP auto-registers with a WLC over CAPWAP and receives its full configuration centrally. No per-AP manual setup is required beyond physical installation. For smaller sites running Mobility Express, the embedded virtual controller supports up to 25 APs while the Nighthawk app (or web GUI) provides intuitive setup. VideoStream multicast-to-unicast conversion ensures reliable delivery of IPTV, lecture capture, and digital signage streams without degrading general WiFi performance for other users on the same AP.

No cracks or structural damage. Fully tested. All ports, radios, and LEDs verified operational. B — Good Light wear consistent with enterprise deployment — minor scuffs or marks on housing. Fully tested. All ports, radios, and LEDs verified operational. Frequently Asked Questions Does this AP work without a Cisco WLC? Yes, via Mobility Express mode. The 1852I can run an embedded virtual controller supporting up to 25 APs, making it suitable for small sites without a dedicated WLC. For larger deployments, a Cisco WLC (2500, 5500, Catalyst 9800 series) or Catalyst Center is required. Does a power adapter come included? No. The AP is powered via PoE. An IEEE 802.3at (PoE+) switch port is recommended for full transmit power. 802.3af standard PoE will power the unit but may operate at reduced radio power. A PoE injector can be purchased separately if your switch lacks PoE. What is the difference between the "I" and "E" model? The "I" in AIR-AP1852I denotes internal antennas — suitable for standard indoor ceiling-mount deployments. The "E" model has external RP-TNC connectors for optional directional or high-gain antennas, suited to longer-range or specialised coverage requirements. What shipping options are available? Shipping costs apply based on size and destination — rates are calculated at checkout. What does the 12-month warranty cover? Reboot IT's 12-month warranty covers hardware defects and functional failures. Physical damage caused after delivery is excluded. Contact our Melbourne support team for warranty claims.
