A wireless network interface controller ( WNIC) is a network interface controller which connects to a wireless network, such as Wi-Fi, Bluetooth, or LTE (4G) or 5G rather than a wired network, such as an Ethernet network. A WNIC, just like other NICs, works on the layers 1 and 2 of the OSI model and uses an antenna to communicate via radio waves.
RF module. An RF module (short for radio-frequency module) is a (usually) small electronic device used to transmit and/or receive radio signals between two devices. In an embedded system it is often desirable to communicate with another device wirelessly. This wireless communication may be accomplished through optical communication or through ...
Remote control. In electronics, a remote control (also known as a remote or clicker[ 1]) is an electronic device used to operate another device from a distance, usually wirelessly. In consumer electronics, a remote control can be used to operate devices such as a television set, DVD player or other digital home media appliance.
The transmission media (often referred to in the literature as the physical medium) used to link devices to form a computer network include electrical cable, optical fiber, and free space. In the OSI model , the software to handle the media is defined at layers 1 and 2 — the physical layer and the data link layer.
A remote keyless system ( RKS ), also known as remote keyless entry (RKE) or remote central locking, is an electronic lock that controls access to a building or vehicle by using an electronic remote control (activated by a handheld device or automatically by proximity). [ 1] RKS largely and quickly superseded keyless entry, a budding technology ...
Wireless telegraphy. A US Army Signal Corps radio operator in 1943 in New Guinea transmitting by radiotelegraphy. Wireless telegraphy or radiotelegraphy is transmission of text messages by radio waves, analogous to electrical telegraphy using cables. [ 1 ][ 2 ] Before about 1910, the term wireless telegraphy was also used for other experimental ...
A personal FM transmitter is a low-power FM radio transmitter that broadcasts a signal from a portable audio device (such as an MP3 player) to a standard FM radio. Most of these transmitters plug into the device's headphone jack and then broadcast the signal over an FM broadcast band frequency, so that it can be picked up by any nearby radio.
Characteristics. Techniques. v. t. e. Wireless communication (or just wireless, when the context allows) is the transfer of information ( telecommunication) between two or more points without the use of an electrical conductor, optical fiber or other continuous guided medium for the transfer. The most common wireless technologies use radio waves.
