Cisco Catalyst 9166 Series (CW9166) vs Aruba (HPE) Aruba AP-755: 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-755

★ 3.5 Value Score

Wi-Fi Standard: Wi-Fi 7 (IEEE 802.11be)
Spatial Streams (MIMO): 4x4 MIMO on each of the 3 radios
Aggregate Throughput: 18.7 Gbps tri-band aggregate (up to 28.8 Gbps in optional dual-5 GHz/6 GHz radio modes)
Radios (bands): Tri-radio: 2.4 GHz, 5 GHz, 6 GHz (concurrent)
Uplink Port Speed: 2x 10GBASE-T RJ-45 (E0, E1), auto-sensing 100 Mbps / 1 / 2.5 / 5 / 10 Gbps
Max Clients: 512 associated clients per radio (SHI listing; per-AP total not confirmed)
PoE Requirement: 802.3bt (Class 6) PoE; 802.3at/af not sufficient for full operation. Draw 40 W (51 W with USB)

✔ Pros: Wi-Fi 7 tri-band with 4x4 MIMO on all three radios; 18.7 Gbps tri-band aggregate rate; Two 10GbE uplinks with multigig auto-negotiation; Dual 10GbE ports support link aggregation and hitless failover; Internal antennas suit standard ceiling deployments; Works with Aruba Central and the 750 Series management stack; Lower power draw than many Wi-Fi 7 peers at this class
✘ Cons: Requires 802.3bt PoE for full functionality, which adds switch cost; Retail price is high compared with Wi-Fi 6E APs such as the AP-655; Max client count is not confirmed in the official datasheet; Some listings show it as end-of-life (RW SKU), so availability varies; Product numbering is inconsistent across sources (S1G84A vs S1G85A); Per-band peak rates (about 1.4 / 5.8 / 11.5 Gbps) need client-side Wi-Fi 7 gear to realize
Est. Price: $1,969 - $2,906
