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 U6 Pro
★ 4.4 Value Score
Technical Specifications
- Wi-Fi Standard: Wi-Fi 6 (802.11ax)
- Spatial Streams (MIMO): 6 total: 5 GHz 4x4 (DL/UL MU-MIMO); 2.4 GHz 2x2 (UL MU-MIMO)
- Aggregate Throughput: 5.3 Gbps (combined; 4.8 Gbps 5 GHz BW160 + 573.5 Mbps 2.4 GHz BW40)
- Radios (bands): Dual-band: 2.4 GHz and 5 GHz
- Uplink Port Speed: 1x 1 GbE RJ45
- Max Clients: 250+ (official Ubiquiti tech specs; some retailers list 300+)
- PoE Requirement: PoE powered, 44-57V DC input, 13W max consumption; 802.3af/at not specified by Ubiquiti; no PoE injector in the spec listing
Curation Review
- ✔ Pros: Wi-Fi 6 with 4x4 MU-MIMO on 5 GHz for good multi-client performance; Aggregate throughput up to 5.3 Gbps across both bands; Low 13W power draw compared with higher-end APs; Works with UniFi Network controller for centralized management; Ceiling or wall mounting with included Pro Mount; Compact, low-profile design (about 197 mm diameter, 35 mm height)
- ✘ Cons: Only a single 1 GbE uplink, which can bottleneck the 5 GHz radio on fast networks; No 2.5 GbE or multi-gig port; PoE standard not clearly specified, so verify your switch or injector supplies enough power; PoE injector is not included with the US model, which adds cost; Client capacity is lower on the official spec (250+) than some retailer marketing claims (300+); Requires a UniFi controller for full feature use
- Est. Price: $159 - $185
