Wireless LAN (WLAN) channels are frequently accessed using IEEE 802.11 protocols. The 802.11 standard provides several radio frequency bands for use in Wi-Fi communications, each divided into a multitude of channels numbered at 5 MHz spacing (except in the 45/60 GHz band, where they are 0.54/1.08/2.16 GHz apart) between the centre frequency of the channel.
IEEE 802.11 is also a basis for vehicle-based communication networks with IEEE 802.11p . The standards are created and maintained by the Institute of Electrical and Electronics Engineers (IEEE) LAN/ MAN Standards Committee (IEEE 802). The base version of the standard was released in 1997 and has had subsequent amendments.
This ensures it can be applied to wireless voice telephony, mobile Internet access, fixed wireless Internet access, video calls and mobile TV technologies. CDMA2000 is a family of 3G mobile technology standards for sending voice, data, and signaling data between mobile phones and cell sites.
Internet Protocol television. An IPTV set-top box connected to a TV set, designed to receive television from a service called Mview. Internet Protocol television ( IPTV ), also called TV over broadband, [ 1][ 2] is the service delivery of television over Internet Protocol (IP) networks.

Duplex (telecommunications) A duplex communication system is a point-to-point system composed of two or more connected parties or devices that can communicate with one another in both directions. Duplex systems are employed in many communications networks, either to allow for simultaneous communication in both directions between two connected ...
Miracast is a wireless communications standard created by the Wi-Fi Alliance which is designed to transmit video and sound from devices (such as laptops or smartphones) to display receivers (such as TVs, monitors, or projectors). It uses Wi-Fi Direct to create an ad hoc encrypted wireless connection [ 1] and can roughly be described as " HDMI ...
A communication channel refers either to a physical transmission medium such as a wire, or to a logical connection over a multiplexed medium such as a radio channel in telecommunications and computer networking. A channel is used for information transfer of, for example, a digital bit stream, from one or several senders to one or several receivers.
Wi-Fi ( / ˈwaɪfaɪ /) [ 1][ a] is a family of wireless network protocols based on the IEEE 802.11 family of standards, which are commonly used for local area networking of devices and Internet access, allowing nearby digital devices to exchange data by radio waves. These are the most widely used computer networks, used globally in home and ...
