Every WhaleyComm unit is professionally tested, reset to factory defaults, and certified by our in-house engineers — the same standard trusted by 5,000+ organisations across 25 years. Not a refurb marketplace. A certified lifecycle partner.
Tested to factory specification. Backed by 25 years of enterprise trust.
This professionally tested, refurbished Cisco Aironet AIR-AP3802I-B-K9 is a dual-band, indoor 802.11ac Wave 2 wireless access point from the enterprise-grade Aironet 3800 Series. Designed for high-density indoor environments, the 3802I features 12 internal cross-polarized antennas, a B regulatory domain, and delivers a theoretical aggregate PHY data rate of up to 5.2 Gbps — making it one of the most capable Wave 2 access points available at this price point. Every unit ships reset to factory defaults and includes a certificate of testing.The AIR-AP3802I-B-K9 is built around 4x4 MU-MIMO with three spatial streams, supporting simultaneous multi-client downlink transmissions to maximize throughput in crowded RF environments. It ships with Cisco Multigigabit Ethernet (mGig), offering uplink speeds of 100 Mbps, 1 Gbps, 2.5 Gbps, and 5 Gbps over Cat 5e or better cabling — future-proofing your wired backhaul. Flexible Radio Assignment (FRA) allows the dual radios to operate in standard 2.4/5 GHz mode or dual 5 GHz mode for maximum 802.11ac Wave 2 performance. Cisco CleanAir technology, ClientLink 4.0 beamforming, and 802.11r/v fast-roaming are all included for enterprise-class reliability. The unit also features a side-mounted modular expansion connector and supports both 802.3at PoE+ and Cisco UPOE for flexible deployment.
WhaleyComm delivers this refurbished Cisco AIR-AP3802I-B-K9 at a fraction of new list price — ideal for enterprise wireless refreshes, campus densification, or high-density deployments where proven 802.11ac Wave 2 performance is required. Backed by our Lifetime Warranty and ISO 9001-certified testing process, this unit ships ready to deploy.

Education — Classrooms and Lecture Halls
Flexible Radio Assignment and CleanAir technology keep performance stable in RF-congested school environments where students connect multiple devices per user.
Healthcare Facilities
Reliable dual-band coverage and fast 802.11r roaming support voice-over-Wi-Fi and mobile clinical applications that require seamless connectivity across large hospital floors.
Warehouses and Distribution Centers
The ruggedized internal antenna design and wide operating temperature range suit warehouse environments where industrial devices and scanners demand consistent, high-throughput wireless access.
Hospitality and Convention Centers
MU-MIMO enables the AP to serve many concurrent guest devices, while the mGig uplink ensures the wired backhaul keeps pace with dense wireless traffic loads.
Wireless Infrastructure Refresh on a Budget
Organizations upgrading from 802.11n or 802.11ac Wave 1 can deploy refurbished 3802I units to achieve Wave 2 performance at significantly reduced capital cost compared to new hardware.
