Hi there.

While you can't break the Laws of Physics for say maximum transfer speeds of specific hardware - if both machine and Router are powerful enough could built in Hardware compression of the signals speed up the transmission between computer and ISP - less physical data would be transferred over say the wifi link - dynamic compression and de-compression could cut down the data sent / received by around 30 - 50 % -- a significant saving especially on wifi.

I haven't seen any of these with built in hardware compression but surely they exist. The compression should ideally be done in the NIC as well avoiding load on the Host computer's CPU.

Maybe wifi protocols already have compression / decompression in them but I don't think so. !!

Please note here -- I'm NOT talking about encrypting signals - that's a whole different issue.
