Cisco Catalyst 9166 Series (CW9166) vs Cisco Catalyst 9136I: 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

Cisco Catalyst 9136I

★ 3.4 Value Score

Wi-Fi Standard: 802.11ax (Wi-Fi 6E), including 6 GHz band
Spatial Streams (MIMO): 4x4 on 2.4 GHz; 8x8 on 5 GHz; 4x4 on 6 GHz (with 802.3bt power). Under 802.3at: 2x2 / 4x4 / 2x2
Aggregate Throughput: Up to 10.2 Gbps aggregate PHY data rate (radio PHY, not achievable client throughput)
Radios (bands): 3 radios: 2.4 GHz, 5 GHz, 6 GHz, plus dedicated Bluetooth/BLE
Uplink Port Speed: 2x multigigabit RJ-45 ports (100M/1G/2.5G/5G); combined link aggregation capped at 5 Gbps
Max Clients: 400 per radio and 1,200 per AP (per Cisco deployment guide; not stated on datasheet)
PoE Requirement: 802.3bt (UPOE) for full performance, 47.3 W max; 802.3at (PoE+) supported at 24.4 W with reduced radio config; 802.3af for staging only with radios off
Dimensions (W x L x H): 9.9 x 9.9 x 2.2 in (25.1 x 25.1 x 5.6 cm), excluding mounting brackets
Form Factor: Indoor ceiling/wall-mount access point with internal antennas

✔ Pros: Tri-band Wi-Fi 6E with dedicated 6 GHz radio; High aggregate PHY rate of up to 10.2 Gbps; Two multigigabit uplinks (2.5G/5G) for higher wired throughput; 8x8 on 5 GHz radio with 802.3bt power; Dual-PoE port redundancy (one active, one standby); Integrated Bluetooth for IoT and location services; Supports 400 clients per radio and 1,200 per AP; Managed through Cisco Catalyst/IOS-XE wireless controllers and Cisco DNA tooling
✘ Cons: Wired uplink throughput capped at 5 Gbps even with both ports aggregated; Full performance requires 802.3bt (UPOE) power, which many switches may not provide; Thermal downgrade above 40 C ambient (5 GHz drops to 4x4, uplinks drop to 1G); Max client and throughput numbers are PHY or deployment-guide figures, not datasheet guarantees; Higher cost than Wi-Fi 6 entry-level APs, with reseller prices varying widely; Requires Cisco wireless controller infrastructure for full management features
Est. Price: $1,966 - $3,010
