Cisco Catalyst 9164 (CW9164I) vs Cisco Catalyst 9166 Series (CW9166): Specs & Price Comparison

Cisco Catalyst 9164 (CW9164I)

★ 3.3 Value Score

Wi-Fi Standard: Wi-Fi 6E (IEEE 802.11ax)
Spatial Streams (MIMO): 4x4 on 2.4 GHz and 5 GHz; 6 GHz listed as 2x2 by one reseller and 4x4 in the Japanese Cisco datasheet (conflicting, verify against the English datasheet)
Aggregate Throughput: 7.49 Gbps theoretical PHY rate (vendor-listed, not measured)
Radios (bands): 3 radios: 2.4 GHz, 5 GHz, 6 GHz (tri-band)
Uplink Port Speed: 1x 2.5GbE RJ-45 (100M/1G/2.5G)
Max Clients: Not confirmed in sources reviewed
PoE Requirement: PoE powered device (PD) on the 2.5GbE port; exact 802.3 class not confirmed in sources reviewed
Management: On-premises with Catalyst 9800 WLCs (IOS XE 17.9.1+ per one listing) or cloud-managed via Meraki (CW9164I-MR SKU)
Bluetooth: Bluetooth 5.1
Antenna: Internal antennas
Memory: 2 GB RAM, 1 GB flash

✔ Pros: Tri-band Wi-Fi 6E with dedicated 6 GHz band for less congested, high-capacity clients; 4x4 MIMO radios on 2.4 and 5 GHz; Single-cable PoE deployment with 2.5GbE uplink; Flexible management: on-prem with Catalyst 9800 controllers or cloud-managed via Meraki SKU; Internal antennas give a low-profile ceiling-mount form factor; Bluetooth 5.1 for IoT and asset-tracking use cases
✘ Cons: Single 2.5GbE uplink caps wired throughput well below the 7.49 Gbps radio rate; Quoted throughput is a theoretical PHY rate, with no independent measured aggregate results found; Price varies widely by seller and SKU (-B, -ROW, -E, -MR), and many listings are refurbished; Spatial stream and PoE class details conflict or are unconfirmed across sources; Requires IOS XE 17.9.1 or later for some configurations, and needs a Catalyst 9800 controller or Meraki license for full management
Est. Price: $1,100 - $1,900

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
