I spend a lot of time thinking about wireless performance in crowded venues. Usually, I am doing it because someone has asked me to evaluate a network, troubleshoot a problem or explain why a design behaves differently when tens of thousands of people arrive. Recently, I found myself conducting an unplanned field test while attending […]

For the better part of a decade, high-density Wi-Fi was a game of managing scarcity. Spectrum was the constraint. Everything we did as engineers, including antenna design, channel planning, and feature development was about extracting performance from a limited resource. We got very good at it. But we were always working around the same fundamental […]
