★ 4.2 Value Score

Technical Specifications

  • Wi-Fi Standard: 802.11ax (Wi-Fi 6E, 6 GHz capable); also 802.11a/b/g/n/ac backward compatible
  • 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
  • Management: Catalyst 9800 wireless controllers (IOS-XE) or Meraki cloud (CW9166I-MR / CW9166D1-MR SKUs)

Curation Review

  • ✔ 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

★ 3.5 Value Score

Technical Specifications

  • Wi-Fi Standard: Wi-Fi 7 (IEEE 802.11be), backward compatible with 802.11ax/ac/a/b/g/n; Bluetooth 5.4 LE and Zigbee radio
  • Spatial Streams (MIMO): 2x2 MU-MIMO on each of the 3 radios (2.4 GHz, 5 GHz, 6 GHz)
  • Aggregate Throughput: 9.3 Gbps tri-radio aggregate (HPE rating)
  • Radios (bands): Tri-radio: 2.4 GHz, 5 GHz, 6 GHz (concurrent), plus dedicated BLE/Zigbee radio
  • Uplink Port Speed: 2x 5GBASE-T multigig RJ-45 (auto-negotiating 100 Mbps / 1 / 2.5 / 5 Gbps), 1x USB-C console/USB, 2x USB
  • Max Clients: 512 associated clients per radio; up to 16 BSSIDs per radio
  • PoE Requirement: 802.3bt (Class 5, 40 W) for unrestricted operation; 802.3at (Class 4, 25.5 W) runs in restricted mode; 802.3af (Class 3) supports staging only. Worst-case draw 24 W on PoE (36 W with USB devices); DC power 20 W (31 W with USB)
  • Form Factor: Indoor campus access point, internal antennas, ceiling or wall mount
  • Product Status: End of life per some reseller listings (SHI); verify availability before purchase

Curation Review

  • ✔ Pros: Wi-Fi 7 tri-band radio with 9.3 Gbps aggregate throughput at a lower price than the AP-755; Two 5GBASE-T multigig uplinks support 2.5 and 5 Gbps wired backhaul without a switch upgrade; Supports up to 512 clients per radio, suitable for dense campus or office deployments; Fully managed through HPE Aruba Central or AOS 10 with the same feature set as the 730 Series; Low worst-case power draw (24 W PoE) fits within 802.3bt Class 5 budgets; Dedicated BLE/Zigbee radio enables IoT and location services
  • ✘ Cons: Only 2x2 spatial streams per band, so per-client throughput and capacity lag 4x4 Wi-Fi 7 APs like the AP-755; Uplink is multigig but not 10GbE, which limits throughput on high-density or 6 GHz heavy deployments; Requires 802.3bt Class 5 PoE for unrestricted operation, so older 802.3at switches disable USB and run in restricted mode; Some reseller listings show it as end-of-life, so availability and support may be limited; Pricing varies widely by region and SKU (for example S1G42A vs S0H13A) and sellers may show discounts from the US list price of $1,995
  • Est. Price: $1,250 - $1,995
