OSI Physical Layer: The physical layer provides for transmission of cells over a physical medium connecting two ATM devices This physical layer is comprised of two sublayers: the PMD Physical Medium Dependent sublayer, and the TC Transmission Convergence sublayer Refer PMD and TC
Physical layer protocol The lowest layer in the networking model In wireless networking, it defines the used signal modulation and RF transmission methods
Physical layer of the Fiber Distributed Data Interface (FDDI) standard Also used to refer to the actual hardware used to implement the physical layer (PHY entity)
Physical Layer Device The name used for a transceiver in Fast Ethernet and Gigabit Ethernet systems
PHY designates the lowest protocol layer specified by the OSI Network Model It deals primarily with transmission of the raw bit stream over the PHYsical transport medium In the case of wireless LANs, the transport medium is free space The PHY defines such parameters as data rates, modulation method, signaling parameters and transmitter/receiver synchronization Within an actual radio implementation, the PHY corresponds to the radio front end and baseband signal processing sections
