Cisco Catalyst 9120AX
★ 3.2 Value Score

Technical Specifications

  • Wi-Fi Standard: 802.11ax (Wi-Fi 6)
  • Spatial Streams (MIMO): 4x4:4 MU-MIMO on both radios with 802.3at/bt PoE; reduced to 1x1 on both radios, or 2x2 on one, under 802.3af
  • Aggregate Throughput: Up to 5.38 Gbps PHY rate (5 GHz at 160 MHz, 2.4 GHz at 20 MHz); dual 5 GHz mode up to 5.2 Gbps (2 x 2.6 Gbps)
  • Radios (bands): 2 main radios: 1 flexible 2.4 GHz or 5 GHz radio, plus 1 dedicated 5 GHz radio. Dual 5 GHz mode is supported. Some variants add a BLE/802.15.4 radio.
  • Uplink Port Speed: 1 x multigigabit RJ-45 port (100/1000/2500 Mbps, IEEE 802.3bz); 2.5 Gbps requires Cat 5e or better. 1 Gbps uplink under 802.3af.
  • Max Clients: Not published in Cisco datasheet
  • PoE Requirement: 802.3at (PoE+) or 802.3bt (UPOE/UPOE+) for full capability, 25.5 W max draw; 802.3af supported at 13.4 W max draw with reduced radio and uplink capability

Curation Review

  • ✔ Pros: Full 4x4:4 on both radios with 802.3at/bt PoE; Wi-Fi 6 (802.11ax) with OFDMA and MU-MIMO for dense client environments; Multigigabit 2.5 Gbps uplink avoids the 1 Gbps bottleneck; Model choice for internal (AXI), external antenna (AXE), or professional external antenna (AXP) deployments; Optional embedded wireless controller (-EWC) variants for small deployments; Dual 5 GHz mode for higher 5 GHz capacity; Supports Cisco power injectors for 802.3af or 802.3at environments
  • ✘ Cons: Full performance needs 802.3at/bt PoE; 802.3af drops radios to 1x1 or 2x2 and the uplink to 1 Gbps; No 5 Gbps or 10 Gbps uplink on the base model; Max client count not published by Cisco; Higher price than many Wi-Fi 6 APs from competing vendors; Some older listings show Wi-Fi 6E or older variants, so confirm the exact part number before purchase; Prices vary widely across resellers and regions and may not reflect current Cisco list pricing
  • Est. Price: $1,550 - $2,863

Technical Specifications

  • Wi-Fi Standard: Wi-Fi 7 (802.11be), tri-band
  • Spatial Streams (MIMO): 6 total; 2x2 MIMO per band (2.4 GHz, 5 GHz, 6 GHz)
  • Aggregate Throughput: 9.3 Gbps (per-band: 2.4 GHz 688 Mbps, 5 GHz 2882 Mbps, 6 GHz 5765 Mbps)
  • Radios (bands): 3 radios: 2.4 GHz, 5 GHz, 6 GHz
  • Uplink Port Speed: 1x 2.5GbE RJ45 (1G/2.5G auto-negotiation)
  • Max Clients: 300+ connected devices
  • PoE Requirement: 802.3at PoE+ (44-57V DC input), approx. 21 W typical draw

Curation Review

  • ✔ Pros: Tri-band Wi-Fi 7 with 6 GHz support at a low entry price; 2.5GbE uplink lets it outrun standard gigabit wired backhaul; single-cable PoE+ power simplifies deployment; 300+ client capacity suits small-to-medium offices and homes; wall and ceiling mounts included; 2-year warranty; managed centrally through the UniFi controller ecosystem
  • ✘ Cons: Only 2x2 MIMO per band, so it trails 4x4-class Wi-Fi 7 APs and the U7 Pro Max; no 10GbE uplink for high-throughput environments; requires a UniFi controller (UniFi OS or Network app) for full management; PoE+ budget leaves no headroom for power-hungry add-ons; street prices often sit above the $189 MSRP; no built-in PoE injector, so a PoE+ switch or injector is required
  • Est. Price: $179 - $237
