★ 3.4 Value Score

Technical Specifications

  • Wi-Fi Standard: Wi-Fi 7 (802.11be); also supports Wi-Fi 6 features (MU-MIMO, OFDMA, BSS Coloring, TWT)
  • Spatial Streams (MIMO): 4x4:4 SS on each radio (2.4 GHz, 5 GHz, 6 GHz; plus second 5 GHz radio in quad-radio mode) with 802.3bt power
  • Aggregate Throughput: 24 Gbps (quad-radio PHY aggregate, marketing figure; no measured client throughput published)
  • Radios (bands): Tri-radio by default: 2.4 GHz, 5 GHz, 6 GHz. Optional quad-radio mode adds a second 5 GHz radio. Also includes a dedicated 2.4 GHz IoT radio and a scanning radio
  • Uplink Port Speed: 2x 10 Gbps mGig PoE-in ports (1/2.5/5/10G); 10 Gbps max aggregate in LAG mode
  • Max Clients: 1200 (400 per radio)
  • PoE Requirement: 802.3bt (Class 6) for full performance: 4x4 on all radios, 10G on both uplinks, USB enabled. 802.3at reduces radios to 2x2 (quad-radio) or 2.5G/1G uplinks and disables USB. 802.3af disables all radios
  • Channel Widths: Up to 320 MHz on 6 GHz; up to 160 MHz on 5 GHz
  • Form Factor: Indoor ceiling/wall-mount AP, 25 x 25 x 5.1 cm, 1.87 kg (mounting bracket not included)
  • Management: Catalyst 9800 WLC (IOS XE 17.15.2+), Catalyst Center, or Meraki cloud (SKU-dependent)
  • Max SSIDs/WLANs: 16 per band

Curation Review

  • ✔ Pros: Tri-band Wi-Fi 7 with 4x4:4 streams on every radio; 6 GHz support with 320 MHz channels; Dual 10G mGig uplinks with LAG for up to 10 Gbps aggregate backhaul; Supports up to 1200 clients (400 per radio); Dedicated IoT and scanning radios for security and RF analytics; Optional quad-radio mode for extra 5 GHz capacity; Manageable from Catalyst 9800/Catalyst Center or Meraki cloud depending on SKU
  • ✘ Cons: Full performance requires 802.3bt (Class 6) PoE, which many switches do not provide; 802.3at power reduces radio and uplink capacity; 802.3af disables all radios; Indoor-only design; Mounting hardware is sold separately; Premium price compared with Wi-Fi 6E and Wi-Fi 6 APs; Regional SKU variants (CFG, RTG, CFG++) complicate sourcing and licensing
  • Est. Price: $2,083 - $2,612

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
