PowerBeam PBE-5AC-400 ac devices feature a multi-radio architecture to power a revolutionary RF analytics engine.nAn independent processor on the Printed Circuit Board Assembly powers a second, dedicated radio, which persistently analyzes the full 5 GHz spectrum and every received symbol to provide you with the most advanced RF analytics in the industry.nUsing Ubiquiti airMAX AC technology, the PBE-5AC-400 supports up to 450+ Mbps real TCP/IP throughput up to triple the throughput of standard airMAX products! airMAX ac supports high data rates, which require dense modulation: 256QAM – a significant increase from 64QAM, which is used in airMAX.
