5.0 GHz 150 Mbit/s Wireless Bridge

The Ubiquiti PowerBeam M5 is a 5.0 GHz wireless access point built for long-range point-to-point or point-to-multipoint links. It delivers up to 150 Mbit/s throughput using IEEE 802.11n with proprietary airMAX TDMA protocol. The integrated RF isolator design provides enhanced interference rejection for clean signal performance. It is powered via PoE for simplified outdoor installation.

Suits installers needing isolated long-range

This unit fits network builders who require a dedicated 5.0 GHz bridge with high RF isolation to cut through noisy environments. The 12.4 mile operating range supports extended links between wired network segments. It is not suited for buyers who need client Wi-Fi access for laptops or phones. It is also not suited for installers requiring gigabit Ethernet throughput on the wired port.

150 Mbit/s airMAX throughput ceiling

The single specification that decides fit is the 150 Mbit/s maximum data rate set by the IEEE 802.11n airMAX implementation. This caps real-world bridge capacity well below modern gigabit expectations. If your link budget demands higher sustained throughput, this model will not meet the requirement. The Fast Ethernet port reinforces this ceiling as the wired bottleneck.

Questions about this item

How do I mount the PowerBeam M5 and aim the 300 mm dish for a 12.4 Mile link?

Secure the integrated bracket to a pole or wall, connect the PoE injector to the Fast Ethernet port, then use the airMAX alignment tool to peak the signal before tightening all hardware.

Which parts of the PBE-M5-300-ISO-US will need replacement after long outdoor exposure?

The PoE injector and Ethernet cable degrade first; the radio and dish are sealed, so only ancillary power and cabling typically require swapping.

What throughput limit appears first when the 150 Mbit/s bridge runs at full load for hours?

The 150 Mbit/s 802.11n PHY ceiling caps sustained throughput; TDMA scheduling prevents contention but cannot exceed that physical rate.
