I am trying to develop a technology-independent channel. Passing 
explicitly to the channel parameters such as WifiMode and WifiPreamble 
make the channel technology-specific, and I think that the channel has 
no real reason to be technology-specific. Only the PHY needs that 
information, that's why I like the idea of not letting it mess up the 
API between Channel and PHY.

By the way, if we had a PHY header as per the 802.11 standard, then we 
wouldn't need to pass WifiMode and WifiPreamble explicitly.
