2. Wireless power transfer - Wikipedia

   en.wikipedia.org/wiki/Wireless_power_transfer

   Generic block diagram of a wireless power system. Wireless power transfer (WPT; also wireless energy transmission or WET) is the transmission of electrical energy without wires as a physical link. In a wireless power transmission system, an electrically powered transmitter device generates a time-varying electromagnetic field that transmits ...

3. Wireless - Wikipedia

   en.wikipedia.org/wiki/Wireless

   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. With radio waves, intended distances ...

4. Radio receiver - Wikipedia

   en.wikipedia.org/wiki/Radio_receiver

   A modern smartphone has several RF CMOS digital radio transmitters and receivers to connect to different devices, including a cellular receiver, wireless modem, Bluetooth modem, and GPS receiver. [145] The development of integrated circuit (IC) chips in the 1970s created another revolution, allowing an entire radio receiver to be put on an IC ...

   New Brunswick Marconi Station (40.51529°N 74.48895°W) was located at County Route 501 and Easton Avenue just a few minutes from the New Brunswick border in Somerset, New Jersey. Today it is the site of Marconi Park. It was an early radio transmitter facility built in 1913 and operated by the American Marconi. [44]

6. Wireless telegraphy - Wikipedia

   en.wikipedia.org/wiki/Wireless_telegraphy

   At the receiver the pulses are audible in the receiver's speaker as beeps, which are translated back to text by an operator who knows Morse code. Radiotelegraphy was the first means of radio communication. The first practical radio transmitters and receivers invented in 1894–1895 by Guglielmo Marconi used radiotelegraphy. [5]

7. MIMO - Wikipedia

   en.wikipedia.org/wiki/MIMO

   At one time, in wireless the term "MIMO" referred to the use of multiple antennas at the transmitter and the receiver. In modern usage, "MIMO" specifically refers to a class of techniques for sending and receiving more than one data signal simultaneously over the same radio channel by exploiting the difference in signal propagation between ...
