PHY and MAC?

PHY stand for 'Physical layer'. A physical layer is the first layer in an OSI stack. PHY layer will define physical and electrical characteristics of the network.

MAC is the abbreviation for 'Medium Access Control' and is the second layer in the OSI stack. The MAC is responsible for sending and receiving RF frames.
