Curation Review
✔ Pros:Multigig 2.5GbE uplink supports higher throughput than 1GbE APs; 4x4 5 GHz radio with 4 spatial streams delivers strong client performance; dedicated third radio supports background scanning and security/RF monitoring; Mist AI cloud management offers automated RRM, analytics and troubleshooting; BLE support enables location and IoT services; sold with subscription options (1, 3 or 5 years) for licensing flexibility
✘ Cons:Wi-Fi 6 only, with no 6E 6 GHz band; 2.4 GHz radio is limited to 2x2 and 575 Mbps PHY; requires a Mist cloud subscription for full functionality, adding recurring cost; pricing varies widely by SKU and region, with no single official list price found; max client count is not officially published in the sources reviewed; PoE requirement is ambiguous across sources (802.3at vs 802.3bt), so verify power budget before deployment
Spatial Streams (MIMO): 4x4:4 on each of the three client radios (2.4 GHz, 5 GHz, 6 GHz); MU-MIMO and OFDMA supported
Aggregate Throughput: Up to 7.78 Gbps tri-radio aggregate (maximum over-the-air PHY/chipset frame rate, not per-client throughput)
Radios (bands): Tri-radio 4x4:4: 2.4 GHz client radio, 5 GHz client radio, 6 GHz client radio; plus tri-band scanning radio (2.4/5/6 GHz) for security/RF analytics and a 2.4 GHz Bluetooth Low Energy radio
Uplink Port Speed: 1x multigigabit RJ45 (100 Mbps / 1 Gbps / 2.5 Gbps / 5 Gbps BASE-T); also 1 USB 2.0 Type-A port
Max Clients: Not published in the sources reviewed
PoE Requirement: 802.3bt (UPOE) 30.5 W for full functionality including USB; 802.3at (PoE+) 25 W supported with reduced functionality and no USB; 802.3af not supported; 54 V DC option available
Form Factor: Indoor ceiling/wall-mount access point; omnidirectional (CW9166I) or directional (CW9166D1) antenna variants
Dimensions: 241.3 x 241.3 x 56.9 mm (CW9166I) / 57.9 mm height (CW9166D1); approx. 1.6 kg
✔ Pros:Tri-band Wi-Fi 6E with 4x4:4 on every client radio for high-density capacity; dedicated tri-band scanning radio for WIPS, spectrum analysis, and location analytics; multigigabit 5 Gbps uplink on a single RJ45 port; Bluetooth Low Energy radio for beacons and asset tracking; supports both Catalyst 9800 controller and Meraki cloud management; full functionality on 802.3bt PoE with USB output
✘ Cons:Full feature set requires 802.3bt (UPOE) power, and 802.3at operation reduces functionality; only one uplink port, so no link aggregation or redundancy; premium price compared with many Wi-Fi 6E APs; maximum client count is not published in available sources; Catalyst (CW9166I-B/-E) and Meraki (CW9166I-MR) SKUs are the same hardware under different management licences, which can confuse purchasing; end-of-sale/end-of-life status is unconfirmed and should be checked with Cisco
