This episode breaks down the physics of signal loss through steel-rebar concrete, then walks through the specific configuration levers you can actually turn: height placement, beamforming, channel selection, and the counterintuitive move of reducing transmit power. We explain why mesh systems fail in dense concrete, why powerline Ethernet is a disaster on gigabit fiber, and how a…
