WLAN PHY Layers as per IEEE 802.11 standardsДЎ1a physical layerвћ¤ 11b physical layerвћ¤ 11n physical layerвћ¤ WLAN 11ac physical layerвћ¤ WLAN 802.11ad Physical layerвћ¤ BER, SNR, spectral efficiency or Bandwidth efficiency, power efficiency).Дifferent PHY layers will have different FEC configurations and modulation formats. The variation in physical layer depends on medium requirement and system performance requirement This will convert bits into symbols for long distance transmission as well as to increase bandwidth efficiency.ДЇollowing table-1 mentions what are different physical layers as per different wireless and wired standards.

It adds modulation and demodulation modules to incorporate modulation and demodulation functionalities.

It adds forward error correction functionality to enable error correction at the receiver.

It converts MAC layer format suitable to be transported over the medium.

Physical medium can be copper wire, fiber optic cable, twisted pair or even wireless channel.ДЇollowing are the functions of PHY layer: It interfaces physical medium with MAC and upper layers. PHY is the short form of Physical Layer or medium. Layer-1 is known as PHY and Layer-2 is known as MAC. Provide reliable communication between peer network layers of two IP enabled devices. They have their own functions as well as they support each other in order to

PHY and MAC layers of wlan, wimax, zigbee, zwave, bluetooth are also mentioned.Д«oth of these are layers reside in OSI stack or OSI 7 layer model. This page on PHY vs MAC helps reader understand basics of PHY layer such as what is PHY medium used, frequency, data rate, This page compares PHY vs MAC layers and mention difference between PHY and MAC layer.
