PowerBeam 5AC 620 is a 5 GHz WiFi bridge from Ubiquiti’s airMAX PowerBeam series, delivering a genuine 450+ Mbps real TCP/IP throughput rate for long-range point-to-point links. Unlike radio-only devices that require a separate antenna, the PowerBeam 5AC 620 integrates a large 620mm dish antenna directly into the unit, making it a complete, ready-to-mount bridge solution out of the box.

The PowerBeam 5AC 620 delivers an impressive 29 dBi antenna gain with dual-linear polarization, giving it substantial reach for long-distance point-to-point links between two fixed locations — connecting buildings across a campus, bridging a warehouse to a main office, or linking sites separated by significant distance. It operates across the 5150–5875 MHz frequency range worldwide, with US/CA coverage spanning U-NII-1 through U-NII-3 bands.

Channel bandwidth support covers 10/20/30/40/50/60/80 MHz in PtP mode and 10/20/30/40 MHz in PtMP mode, giving network designers flexibility depending on the link configuration. The PowerBeam 5AC 620 supports airMAX AC Mode, Ubiquiti’s proprietary TDMA-based protocol that improves scalability and reduces collision-related performance loss, along with Discovery Protocol, Frequency Band Offset, and Traffic Shaping with Burst Support.

Distance adjustment features include both Ackless Mode and Dynamic Ack, automatically or manually tuning acknowledgment timing to maximize throughput efficiency over long-range links. QoS is handled through WMM packet classification with High, Medium, and Low priority tiers, while a full services suite covers bridging, DHCP, ping watchdog, routing, SNMP, SSH, and webserver access for comprehensive remote management.

Built for genuinely demanding outdoor installation, the PowerBeam 5AC 620 features an outdoor UV-stabilized polycarbonate enclosure rated to withstand wind loading up to 1510N at 200km/h without a radome, or 1830N at 200km/h with one, and carries a wind survivability rating of 200km/h (125mph) — reflecting its design for exposed, high-wind mounting locations. ESD protection reaches ±24kV for both air and contact discharge.

The PowerBeam 5AC 620 undergoes rigorous environmental qualification testing, including salt fog testing (IEC 68-2-11, equivalent to MIL-STD-810G), temperature shock testing, UV exposure testing, vibration testing, and wind-driven rain testing — giving genuine confidence for coastal, desert, or otherwise harsh installation environments.

Connectivity includes 1 GbE RJ45 port, powered via passive PoE 2-pair using the included 24V, 0.5A gigabit PoE adapter, with a supported voltage range of 20-27V DC and maximum power consumption of just 8.5W. At 6.4kg and 620 x 620 x 386mm, the unit includes a pole mount bracket and operates across an extreme -40°C to 70°C temperature range, carrying FCC, IC, CE, and RoHS certification.

For WISPs and integrators needing a complete, high-gain point-to-point bridge without sourcing a separate antenna, the PowerBeam 5AC 620 delivers serious long-range throughput and genuine weatherproof durability in a single, ready-to-deploy package.
