Curation Review

  • ✔ Pros: Wi-Fi 6 (802.11ax) delivers 4x higher throughput and 4x lower latency than Wi-Fi 5; Excellent for high-density deployments (600+ clients); Energy-efficient with lower power consumption than previous generations; Supports fast roaming (802.11k/v/w) for seamless mobility; Compact form factor suitable for modern office aesthetics; Strong security with WPA3 support; Dual-band reduces interference with simultaneous 2.4GHz and 5GHz operation
  • ✘ Cons: Requires PoE+ infrastructure which adds deployment cost; 1 Gigabit uplink can become bottleneck in high-throughput scenarios; Premium pricing compared to Wi-Fi 5 alternatives; Single uplink port limits failover options without additional equipment; Requires compatible Catalyst wireless controller or cloud-managed dashboard; May be overkill for basic office needs with lower client density
  • Est. Price: $1,250 - $1,650
