★ 4.3 Value Score

Technical Specifications

  • Wi-Fi Standard: Wi-Fi 7 (802.11be)
  • Spatial Streams (MIMO): 4x4 MU-MIMO per client-serving radio (4 spatial streams per radio)
  • Aggregate Throughput: 24 Gbps aggregate (concurrent 2.4 GHz, 5 GHz and 6 GHz radios)
  • Radios (bands): 4 client-serving radios: tri-band 2.4 GHz / 5 GHz / 6 GHz with a 4th radio (quad-radio design)
  • Uplink Port Speed: 2x 10 Gbps mGig ports (multi-gigabit Ethernet)
  • Max Clients: 1200 (400 per radio)
  • PoE Requirement: 802.3bt (PoE++) required for full operation; 802.3at/af supports reduced functionality; draws approx. 30-52 W

Curation Review

  • ✔ Pros: Wi-Fi 7 with tri-band 2.4/5/6 GHz and 4x4 MU-MIMO on every radio; 24 Gbps aggregate throughput for high-density environments; dual 10 Gbps mGig uplinks avoid a 1 Gbps bottleneck; rated for up to 1200 clients; supports 802.3bt PoE on the mGig ports with at/af fallback; manageable from Catalyst 9800 WLC/Catalyst Center or Meraki cloud depending on SKU
  • ✘ Cons: Requires 802.3bt PoE for full functionality, which raises switch and injector cost; needs Catalyst 9800 controller running IOS XE 17.15.2 or later for the Catalyst SKU; Wi-Fi 7 benefits need Wi-Fi 7 clients to be realized; list pricing varies widely by reseller and SKU (CFG vs Global vs RTG), and reseller spec figures differ in places; cloud-managed (Meraki) deployment requires separate licensing; premium cost compared with Wi-Fi 6E alternatives
  • Est. Price: $1,681 - $2,996

★ 0.0 Value Score

Technical Specifications

  • Wi-Fi Standard: IEEE 802.11be (Wi-Fi 7), backward compatible with 802.11a/b/g/n/ac/ax
  • Spatial Streams (MIMO): 4x4 MU-MIMO (4 spatial streams) on 2.4 GHz, 5 GHz and 6 GHz client radios
  • Aggregate Throughput: 18 Gbps theoretical PHY (tri-radio, 802.11be); sustained client throughput not published by Cisco
  • Radios (bands): Tri-band client radios: 2.4 GHz (20 MHz, 688 Mbps PHY), 5 GHz (up to 160 MHz, 5,700-5,764 Mbps PHY), 6 GHz (up to 320 MHz, 11,520-11,529 Mbps PHY); plus dedicated tri-band scanning radio, 2.4 GHz IoT radio, UWB, GNSS and BLE 5.3 radio
  • Uplink Port Speed: 1x multigigabit RJ-45 (100M/1G/2.5G/5G/10G BASE-T); 10 Gbps requires Cat6/Cat6A cabling
  • Max Clients: Not stated in Cisco datasheet
  • PoE Requirement: 802.3bt (UPOE) recommended for full operation (39 W Class 5 in power table; datasheet text references Class 6 / 60 W); 802.3at supports 2.5G with 2.4 GHz at 2x2; 802.3af for low-power staging only with radios off
  • Antennas: Internal omnidirectional; peak gain 5 dBi (2.4 GHz), 6 dBi (5 GHz and 6 GHz)
  • Other Ports: 1x management console RJ-45 (115,200 bps default); 1x USB 2.0 (9 W, 802.3bt only); Kensington lock slot
  • Dimensions / Weight: 9.5 x 9.5 x 2.0 in (241 x 241 x 51 mm) excluding mount plate / 3.4 lb (1.56 kg)
  • Management: Catalyst 9800 WLC or Catalyst Center (IOS XE 17.15.2 or later); Meraki cloud management in Meraki SKU variant
  • Price Note: Retailer listings only; no official Cisco list price found. Low end is a sale price for the CFG SKU; high end is a US MSRP-style figure for a related listing

Curation Review

  • ✔ Pros: Tri-band Wi-Fi 7 with 4x4 MU-MIMO on all client radios and 320 MHz channels on 6 GHz; Dedicated tri-band scanning radio for continuous RF monitoring and security; Multigigabit uplink up to 10 Gbps, avoiding 1G bottlenecks for high-density traffic; Integrated IoT, UWB, GNSS and BLE 5.3 radios for location and sensor use cases; Flexible management through Catalyst 9800 WLC/Catalyst Center or Meraki cloud, depending on SKU
  • ✘ Cons: Max client count is not published in the datasheet, making capacity planning harder; The 18 Gbps aggregate is a theoretical PHY figure, not real-world throughput; 10 Gbps uplink requires Cat6/Cat6A cabling and 802.3bt PoE for full performance; Power requirements are inconsistent across Cisco's documents (Class 5 at 39 W vs Class 6 at 60 W), so the injector or switch must be verified; Premium price compared with Wi-Fi 6E alternatives, with wide retailer price variance and confusing SKU suffixes (CFG, RTG, Meraki variants)
  • Est. Price: $1,183 - $2,507
