Cisco Catalyst 9166 Series (CW9166) vs Aruba (HPE) Aruba AP-655: Specs & Price Comparison

Cisco Catalyst 9166 Series (CW9166)

★ 4.2 Value Score

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)

✔ 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
Est. Price: $1,136 - $3,317

Aruba (HPE) Aruba AP-655

★ 3.7 Value Score

Wi-Fi Standard: Wi-Fi 6E (802.11ax) with 6 GHz support; backward compatible with 802.11a/b/g/n/ac
Spatial Streams (MIMO): 4x4:4 MU-MIMO with OFDMA per radio (tri-radio)
Aggregate Throughput: 7.8 Gbps combined (HPE rated across 2.4, 5 and 6 GHz radios)
Radios (bands): Tri-radio: 2.4 GHz, 5 GHz and dedicated 6 GHz
Uplink Port Speed: 2x multigig RJ-45 ports (100M/1G/2.5G/5G); dual 5 GbE with failover or aggregation
Max Clients: 512 concurrent clients; 16 SSIDs
PoE Requirement: 802.3bt Type 3 (PoE Class 4) recommended; 802.3at-only power is not supported for full operation; worst-case draw about 40.3 to 46.5 W

✔ Pros: Tri-radio design with a dedicated 6 GHz radio for Wi-Fi 6E capacity and reduced co-channel interference; 4x4:4 MU-MIMO with OFDMA on each radio supports high-density clients; Two multigig uplinks (up to 5 GbE) with failover or link aggregation avoid the 1 GbE backhaul bottleneck; Rated up to 7.8 Gbps aggregate throughput; Managed through Aruba Central with zero-touch provisioning and WPA3 security
✘ Cons: Requires 802.3bt (PoE++) switch power for full operation, so older 802.3af/at switches are insufficient; Wi-Fi 6E is one generation behind Wi-Fi 7 gear; Higher price than dual-band Wi-Fi 6 APs, at roughly $1,450 to $2,195; Client limit of 512 can be a constraint in very dense venues; Spec figures vary across resellers and datasheet access was limited, so PoE class and throughput should be confirmed against HPE's official datasheet; Regional SKUs (US, RW, TAA, EG) differ in price and compliance
Est. Price: $1,450 - $2,195
