IR data rate limit

What's the approx limit for systems that distribute data via IR in a room sized (10m x 10m) environment? transmitter power in the low watts



I assume that one way of calculating it is to assume the limiting problem is multiple paths. So if we assume a worst case of two bounces we end up with a wavelength of some 30m and a bandwidth of 10MHz. Plausible? Has one done it?

I was referring to pulse length representing a bit.

Wouldn't it be better to first define the data rate you need?
