Editing Physical layer (section)

===Other applications===
* [[Wireless LAN]] or [[Wi-Fi]]: The PHY portion consists of the RF, mixed-signal and analog portions, that are often called transceivers, and the digital baseband portion that use [[digital signal processor]] (DSP) and communication algorithm processing, including [[channel code]]s. It is common that these PHY portions are integrated with the [[medium access control]] (MAC) layer in [[system-on-a-chip]] (SOC) implementations. Similar wireless applications include [[3G]]/[[4G]]/[[3GPP Long Term Evolution|LTE]]/[[5G]], [[WiMAX]] and [[Ultra-wideband|UWB]].
* [[Universal Serial Bus]] (USB): A PHY chip is integrated into most USB controllers in hosts or [[embedded system]]s and provides the bridge between the digital and modulated parts of the interface.
* IrDA: The [[Infrared Data Association]]'s (IrDA) specification includes an IrPHY specification for the physical layer of the data transport.
* [[Serial ATA]] (SATA): Serial ATA controllers use a PHY.
