Three decades of physical layer delivery. Before it had a name.
David Barrett founded AAA Communications in 1992 with a straightforward belief: the physical layer either works or it does not, and every network problem eventually traces back to it. We were delivering structured cabling, fibre, and physical layer assurance before "Layer 1 assurance" was a recognised category. We built our reputation on being the team you call when the physical layer has to be right.
We have operated through the transition from analogue to digital, from Cat3 to Cat6A, from 10Mbps to 10GBase-T, from macro cellular to in-building 4G/5G DAS. Through every transition, one thing has stayed constant: the physical layer has to be right before anything above it can perform.
