PowerBeam ac 2.4 GHz bridge

The PowerBeam ac is a high-performance airMAX AC bridge operating at 2.4 GHz for long-range point-to-point links. It delivers up to 330 Mbit/s throughput under the IEEE 802.11ac standard. The integrated design suits installers deploying wireless backhaul across properties or campuses.

Integrated radio and pole mount

Inner Feed technology places the radio inside the feed horn to cut cable loss and simplify outdoor mounting. A single 10/100/1000 Mbps LAN port connects via the included 0.5A Gigabit PoE adapter for power and data over one cable. The pole-mounting kit secures the 11.4 by 16.5 inch dish on standard masts.

Upgrade from legacy 2.4 GHz gear

This unit replaces older 802.11n bridges that struggle with noise in dense RF environments. The airMAX AC protocol and selectable 10, 20, or 40 MHz channel widths improve capacity and link stability. The jump is worth it when throughput demands exceed what narrow-channel legacy hardware can sustain.

Questions about this item

What throughput does the 802.11ac link actually deliver?

The bridge is rated at 330 Mbit/s over the 2.4 GHz airMAX ac connection; the single Gigabit Ethernet port passes traffic at up to 1000 Mbit/s.

What mounting hardware fits the 11.4 by 16.5 inch dish?

A pole-mounting kit is included; the unit weighs 3.96 lb and measures 11.4" high by 16.5" wide by 16.5" deep, so the mast must support that size and weight.

How do you power the radio and where is the common mistake?

Connect the Ethernet cable to the 0.5 A Gigabit PoE adapter’s PoE port, not the LAN port; the adapter injects power over the same cable that carries data.
