Curation Review
- ✔ Pros: Tri-band 4x4 Wi-Fi 6E radios on 2.4, 5, and 6 GHz; Up to 7.78 Gbps PHY aggregate rate; Multigigabit uplink supports 2.5G and 5G Ethernet; Bluetooth included; Available as on-premises (-B/-Z) and cloud-managed (-MR) SKUs
- ✘ Cons: Single Ethernet port caps wired throughput well below the 7.78 Gbps PHY figure; Aggregate rate is theoretical, not real-world throughput; Max client count not confirmed in sources; PoE requirement not confirmed; Indoor-only deployment; Street prices vary widely by SKU and region
- Est. Price: $1,136 - $3,317
Compare Against
Ubiquiti UniFi U7 Pro
★ 5.0 Value Score
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)

- 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
