- Physical Signaling Layer; provides for the transmission of data through a communications channel by defining the electrical, mechanical, and procedural specifications according to IEEE standards. The PHY is the lowest layer within the OSI reference model. It deals primarily with transmission of the raw bit stream over the transport medium. In the case of wireless LANs, the transport medium is free space. The PHY defines parameters such as data rates, modulation method, signaling parameters, transmitter/receiver synchronization, and so on. Within an actual radio implementation, the PHY corresponds to the radio front-end and baseband signal-processing sections.
Success Stories

I literally just came out of the testing centre having taken the CWDP exam. The certification process opened my mind to different techniques and solutions. This knowledge can only broaden your perspective. Great job, CWNP, you have a great thing going on here.
