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.
Enterprise-grade 802.11ac Wave 2 wireless performance, professionally tested and ready to deploy.
This refurbished Cisco AIR-AP3802I-B-K9 is a Cisco Aironet 3800 Series indoor wireless access point built for demanding enterprise environments. Every unit has been professionally tested and reset to factory defaults, giving you a reliable, deployment-ready platform at a fraction of new pricing. The B regulatory domain designation makes this unit purpose-built for United States deployments. Internal antennas and a low-profile form factor make it ideal for ceiling or wall mounting across office floors, classrooms, and high-density common areas.The AIR-AP3802I-B-K9 delivers 802.11ac Wave 2 with 4x4 MU-MIMO supporting three spatial streams, enabling theoretical aggregate PHY data rates up to 5.2 Gbps across dual bands. A dedicated 5 GHz radio pairs with a Flexible Radio Assignment second radio that can operate as either 2.4 GHz or an additional 5 GHz radio — allowing administrators to run dual 5 GHz for maximum Wave 2 throughput in high-density environments. Multigigabit Ethernet (mGig) uplink support at 100 Mbps, 1 Gbps, 2.5 Gbps, and 5 Gbps over Cat 5e keeps the uplink from becoming the bottleneck. Cisco CleanAir, ClientLink 4.0 beamforming, and 160 MHz channel bonding round out a feature set built for mission-critical wireless.
At $69, this refurbished unit represents outstanding value compared to new list pricing. WhaleyComm has been placing certified refurbished Cisco wireless infrastructure into enterprise networks for 25+ years, serving 5,000+ customers. Every unit ships with our Lifetime Warranty — if it fails under normal operating conditions at any point, we replace it at no cost.

Ideal Use Cases
High-Density Campus and Office Deployments
The 4x4:3 MU-MIMO architecture and dual-radio design allow the AP to simultaneously serve multiple client streams, making it well suited for open offices, conference centers, and campus buildings with high concurrent user counts.
Dual 5 GHz High-Throughput Environments
Flexible Radio Assignment lets administrators reconfigure both radios to 5 GHz, doubling 5 GHz capacity for auditoriums, trading floors, or any venue where 802.11ac Wave 2 throughput is the priority.
Multigigabit-Ready Network Upgrades
The onboard mGig port supports uplink speeds of 2.5 Gbps and 5 Gbps over existing Cat 5e cabling, allowing organizations to increase wireless backhaul capacity without rewiring infrastructure.
Controller-Based Enterprise WLAN Expansion
Full compatibility with Cisco Wireless LAN Controllers (2500, 3500, 5500, 8500, and 9800 Series) and Cisco DNA makes this AP a natural fit for enterprises expanding an existing Cisco-managed wireless network.
Education and Healthcare Facilities
The low-profile internal-antenna design and ceiling-mount form factor blend into facility aesthetics while delivering reliable coverage for classrooms, libraries, patient wards, and clinical spaces.
Budget-Conscious Enterprise Wireless Refresh
At $69 refurbished, the AIR-AP3802I-B-K9 delivers Wave 2 performance at a steep discount versus new, making it an efficient choice for large-scale access point refreshes where capital budgets are constrained.
