Television and Radio?
Bluetooth technology
Wireless communication was first demonstrated in 1866, and the first radio transmission was sent in 1895 by Guglielmo Marconi.
Up until the invention of radio, communication had to be sent long distances along wires and cables. i.e. telegraph or telephone. With the invention of radio, communication was not restricted to the use of wires. Hence wireless is two words 'wire' and 'less' meaning without wire.

Neither this website nor this contributor is qualified to say flatly yes or no, such radiation is dangerous or totally benign. But we can tell you this: Wireless mobile data communication, and its older brother, cellular telephone communication, have exactly the same effect on you as any of these other things has: -- newscasts on AM radio -- the walkie-talkie carried by state police -- the radio in the taxi-cab -- rock music on FM radio -- the RF beam from your garage-door opener -- the Bluetooth cyborg ear sticking out of the side of your face -- the wireless Wi-Fi modem in your house -- the Wi-Fi card in your laptop computer -- the overhead pod that grabs your toll as you drive through the highway tool-booth -- the RF that leaks out of the microwave when you make popcorn or heat meatloaf

Concrete interferes with wireless communication by weakening the signal of the radio frequency. Concrete's ability to weaken or completely stop radio frequencies from travelling through it are what causes the interference.

It is the set area of radio frequencies on which wireless communication is formed upon.
Wireless in its earlier use meant communication without wires. Early radio. Electronics may or may not have anything to do with communication.
A functioning SATELLITE that receives and transmits or retransmits radio-communication signals to or from a base station.
normally, it is where a radio wave is interfering with the communication wave that you are sending out (I think).
Wireless telegraphy is an expression describing early radio telegraph communication, particularly between 1880 and 1920, before the term radio was used.
Wireless communication is usually a form of radio communication. Radio communication uses a part of the electro-magnetic spectrum of radiation. Microwave ovens also use electro-magnetic radiation. If you have a radio that's operating close to the microwave range, or maybe an microwave oven that has a wide spectrum, then the oven can interfere with the radio.
A wireless transmitter is made up of magnets which dispatch a magnetic field that continually flips polarity back and forth, thus creating a radio wave which transmits.
