★ 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

Curation Review

  • ✔ 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
