Microwave Backhaul

The most underrated technology in North America!

A little history… Like any technology, microwave systems have seen dramatic advances in every decade for the past 50 years 1960’s: introduction of solid-state designs in the 1970’s: the move from analog to digital microwave systems 1980’s: the development of synthesized frequency tuning 1990’s: the emergence of compact split-mount designs, spectrally efficient QAM modulation, widespread adoption of the higher frequency bands, from 23 to 38 GHz 2000’s: the introduction of integrated Ethernet/IP transport features and intelligence At the same time, microwave systems have become smaller, more power efficient, software driven, and more cost effective continuing innovation
