I think your fag packet calculation has got a power of ten wrong somewhere. Wi-fi is GHz so that would be on the order of centimetres I think.
Yes. Wifi is 2.4 GHz, speed of light is 0.3 Gm/s. Therefore one wavelength is 0.3/2.4 m/s/Hz = 12.5 cm
Yeah, you’re right. Writing it smaller than 12.5 cm should do it, which is entirely reasonable.
