★ 3.4 Value Score

Technical Specifications

  • Wi-Fi Standard: Wi-Fi 7 (802.11be, also supports 802.11ax/ac/a/b/g/n); tri-band 2.4/5/6 GHz; 6 GHz up to 320 MHz channels
  • Spatial Streams (MIMO): 4x4:4SS per client-serving radio; 12 SS total in default tri-radio mode, 16 SS total in quad-radio mode
  • Aggregate Throughput: Up to 24 Gbps aggregate PHY rate (reseller figure; not stated in Cisco's datasheet, and not measured throughput)
  • Radios (bands): Default tri-radio: 2.4 GHz (20 MHz), 5 GHz (20/40/80/160 MHz), 6 GHz (20/40/80/160/320 MHz). Quad-radio mode adds a second 5 GHz radio (20/40/80/160 MHz). Plus a dedicated scanning radio and a dedicated 2.4 GHz IoT radio
  • Uplink Port Speed: Two 10 Gig mGig ports (mGig0, mGig1) plus console; 10 Gbps needs CAT6 (up to 50 m) or CAT6a (up to 100 m); LAG caps aggregate at 10 Gbps
  • Max Clients: 1,200 total (400 per radio); 16 SSIDs per band
  • PoE Requirement: 802.3bt (PoE++, Class 6) for full performance with both 10G ports and 16 SS; 802.3at reduces radios to 8 SS (quad-radio uses 2.5G ports, tri-radio uses 1G); 802.3af runs a single 1G port with most radios disabled and no MLO. Power budget in watts not stated
  • Antenna: Integrated omnidirectional; 4 dBi (2.4 GHz), 5 dBi (5 GHz), 6 dBi (6 GHz); built-in GPS/GNSS with external antenna option
  • Dimensions / Weight: 9.9 x 9.9 x 2.0 in; 4.1 lb (1.87 kg)
  • Operating Temperature: 0 to 50 C (32 to 122 F)
  • Pricing Notes: No official Cisco list price found; resellers cite MSRP $3,009.98; observed street prices roughly $1,300 to $2,360 (RTG and CFG SKUs differ)

Curation Review

  • ✔ Pros: Wi-Fi 7 tri-band (2.4/5/6 GHz) with 320 MHz channels on 6 GHz; 4x4 per serving radio gives up to 16 spatial streams in quad-radio mode; Dedicated scanning and IoT radios for security and BLE/IoT workloads; Dual 10G mGig uplinks for high-throughput backhaul; High client capacity (1,200 clients, 400 per radio); Built-in GNSS for location services; Optional quad-radio mode adds a second 5 GHz radio for capacity
  • ✘ Cons: Full performance requires 802.3bt (Class 6) PoE, which many switches don't provide; 802.3at or 802.3af significantly reduce radio and port capability; Premium price compared with typical Wi-Fi 6/6E APs; Official datasheet does not state a PoE wattage budget or aggregate throughput; Pricing and SKU variants (RTG vs CFG) vary widely across resellers; Cisco's own deployment guide has a typo ('803.2bt') in the PoE section, so verify requirements before purchase
  • Est. Price: $1,442 - $2,360

★ 4.3 Value Score

Technical Specifications

  • Wi-Fi Standard: 802.11be (Wi-Fi 7), backward compatible with 802.11a/b/g/n/ac/ax; Wi-Fi Alliance Wi-Fi 7 (R1) certified
  • 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
  • Est. Price: $3,548 - $4,790
