If they haven't done so already, maybe we'll see copper-clad drywall or flooring for such environments ? Guess that would take down cellular service too though.

- Klathmon 10y agoI'm just waiting for a standard which smartly reduces transmit power so they all don't need to shout over each other.
- hchenji 10y agoReducing transmit power reduces interference, but it also reduces capacity since the received power (and hence the SNR at the receiver) is reduced! The Shannon limit on channel capacity dictates exactly how much bit rate (C=B*log2(1+SNR)) is achievable over a channel. SNR is a fundamental ingredient of this equation.
- askvictor 10y agoAlso, copper is pretty expensive. A mesh of cheaper metal should do the job; might even be possible to tune it to the right frequency so you don't block cellphones, but I don't know
