Spatial Streams (MIMO): 4x4:4SS on each of the three serving radios (12 total); 2.4 GHz drops to 2x2 under 802.3at
Aggregate Throughput: Up to 18 Gbps PHY rate (802.11be, 4x4 at 320 MHz on 6 GHz, 160 MHz on 5 GHz, 20 MHz on 2.4 GHz); not a sustained throughput figure. Per-band PHY maximums per Meraki datasheet: 6 GHz 11,520 Mbps, 5 GHz 5,700 Mbps, 2.4 GHz 688 Mbps. Some listings cite 23 Gbps, which Cisco's datasheet appears to have as a typo
Radios (bands): Three 4x4 serving radios (2.4 GHz, 5 GHz, 6 GHz); dedicated tri-band scanning radio (WIDS/WIPS, spectrum analysis); 2.4 GHz IoT radio; integrated BLE 5.3 (upgradable to BLE 6.0 in software); integrated GNSS/GPS and UWB
Uplink Port Speed: 1x RJ-45 multigigabit (100M/1G/2.5G/5G/10G); 10G requires Cat6/Cat6A cabling; plus 1x USB 2.0 (9W) and 1x RJ-45 management console
Max Clients: 1,200 total per Cisco scale (400 per radio); Cisco does not state a recommended practical client count
PoE Requirement: 802.3bt Class 5 (UPOE), 39W max, required for 10G uplink, 4x4 on all bands and USB; 802.3at (25.5W) gives 2.5G uplink, 2x2 on 2.4 GHz and no USB; 802.3af (13.95W) for staging only with radios off. Cisco recommends CW-INJ-8 injector
Antenna / Form Factor: Indoor, internal omnidirectional antennas (5 dBi 2.4 GHz, 6 dBi 5/6 GHz); directional variant is CW9176D1; 9.5 x 9.5 x 2.0 in (24 x 24 x 5.1 cm), 3.4 lb (1.56 kg)
Management: Catalyst 9800 Series Wireless Controller (on-premises) or Meraki cloud management, depending on SKU; Meraki requires a license
Price Source: Single reseller only (Aztek Computers, CW9176I-CFG, new, $3,547.97 current, $4,789.76 struck-through reference). No Cisco list price found. Cisco directs buyers to its price list or a partner quote
Curation Review
✔ Pros:Tri-band Wi-Fi 7 with 4x4 on all three client radios, giving high per-client throughput on 2.4, 5 and 6 GHz; Dedicated tri-band scanning radio supports 24/7 WIDS/WIPS and spectrum analysis without taking a client radio out of service; Integrated BLE 5.3, GNSS and UWB radios support asset tracking and location services in one AP; 10G mGig uplink removes the 1G bottleneck for Wi-Fi 7 traffic when 802.3bt PoE is available; Flexible management: Catalyst 9800 controller or Meraki cloud, with 1,200-client scale per Cisco; Wi-Fi 7 (R1), WPA3 and Suite B certifications
✘ Cons:10G uplink and full 4x4 radio operation need 802.3bt (39W) PoE; 802.3at drops to 2.5G, reduces the 2.4 GHz radio to 2x2 and disables USB, which can force switch upgrades; Advertised 18 to 23 Gbps figures are PHY rates, not real-world throughput, and vendor sources disagree on the 23 Gbps value; Only one 10G uplink port and no second uplink for redundancy; Indoor omnidirectional model only; the directional variant is a separate SKU (CW9176D1); Meraki-managed SKUs require an ongoing license; Pricing data is limited to one reseller, and no official Cisco list price was found; Spec sources conflict on PoE (Cisco says 39W, a Meraki document says 60W Class 6), so verify before purchase

Technical Specifications
Wi-Fi Standard: IEEE 802.11ax (Wi-Fi 6/6E); legacy 802.11a/b/g/n/ac also supported
Spatial Streams (MIMO): 4x4:4 on each of the three radios (2.4 GHz, 5 GHz, 6 GHz); 12 spatial streams total for MU-MIMO
Aggregate Throughput: 7.78 Gbps tri-radio PHY maximum (4x4 160 MHz on 6 GHz, 4x4 80 MHz on 5 GHz, 4x4 20 MHz on 2.4 GHz); Cisco notes this is a radio frame-rate capability and may exceed 802.11ax-allowed rates, so real-world throughput is lower
Radios (bands): Tri-radio: 2.4 GHz 4x4, 5 GHz 4x4 plus a secondary XOR radio, 6 GHz 4x4 (LPI); dedicated Bluetooth 5.1 (BLE) radio
Uplink Port Speed: 1x multigigabit Ethernet RJ-45 (100M/1G/2.5G/5G)
Max Clients: Not published in Cisco datasheet (Cisco states higher client density than typical enterprise APs, without a number)
PoE Requirement: 802.3bt (UPOE) 30.5 W for full operation (USB 4.5 W); 802.3at 25.5 W (no USB, reduced operation); 802.3af 14.0 W for configuration staging only with radios off; optional 54 V DC input via MA-PWR-50WAC
Form Factor: Indoor ceiling/wall-mount AP; 9.5 x 9.5 x 2.2 in (241.3 x 241.3 x 56.9 mm) for CW9166I; 3.54 lb (1.60 kg)
Management: On-premises (IOS XE / Catalyst 9800) or cloud via Meraki Dashboard (CW9166I-MR / CW9166D1-MR)
Curation Review
✔ Pros:Tri-band Wi-Fi 6E with dedicated 6 GHz radio for less congested high-capacity spectrum; Four 4x4 spatial streams per band with 7.78 Gbps tri-radio PHY capability; Multigigabit uplink up to 5 Gbps for higher aggregate throughput than 1 GbE APs; Dedicated Bluetooth 5.1 radio for IoT and asset-tracking use; Cisco Trust Anchor, Secure Boot and image signing for hardware-level security; Flexible management: on-premises Catalyst 9800 or cloud-managed Meraki variant; Directional (D1) and omni (I) antenna SKUs for different coverage designs
✘ Cons:Full performance requires 802.3bt (30.5 W) PoE; 802.3at switches limit USB and radio operation; Max client count is not published, so capacity planning relies on third-party or community estimates; Uplink tops out at 5 Gbps, which can bottleneck a 7.78 Gbps radio capability at high load; Price is high relative to many 802.11ax APs, with reseller prices spanning roughly $1,100 to $3,300; Multiple SKUs (I vs D1, -ROW/regional, IOS XE vs Meraki-MR) complicate ordering and comparison; Minimum IOS XE version differs by SKU and reseller listings conflict
