What is the science behind wireless communication?

The transmitter takes information like audio or video, encodes it into a sine function, and transmits the function into the air in the form of an electromagnetic wave. The receiver detects the wave and decodes the data. Antennas are used by both transmitters to transmit waves and by receivers to detect them.

What was the first use of wireless communication?

“The world’s first wireless telephone conversation occurred in 1880, when Alexander Graham Bell and Charles Sumner Tainter invented and patented the photophone, a telephone that conducted audio conversations wirelessly over modulated light beams (which are narrow projections of electromagnetic waves).”

How this wireless communication become possible?

How wireless communication takes place? For wireless communication to take place we require data to be transported without wires. This data is transported using what we call signals(electromagnetic waves). The antenna then radiates the alternating current as an electromagnetic wave.

What are some examples of communication waves?

Radio waves are used for communication such as broadcasting television and radio, communications and satellite transmissions. Radio waves are transmitted easily through air.

Who is the father of wireless communication?

Guglielmo Marconi – the father of wireless communication and recipient of the 1909 #NobelPrize in Physics – died #OTD in 1937. In the late 1800s Marconi was able to use recently discovered radio waves to transmit signals across the English Channel, from Britain to France.

What is wireless communication and when was it discovered?

In 1894, Guglielmo Marconi began developing a wireless telegraph system using radio waves, which had been known about since proof of their existence in 1888 by Heinrich Hertz, but discounted as a communication format since they seemed, at the time, to be a short range phenomenon.

What is wireless communication?

Wireless communication refers to the transfer of information among two or more points without an electrical conductor. The most common wireless technologies use radio. Wireless communications are employed in many smart grid applications, such as meter data collection, demand management, substation and power line monitoring and protection.

Do wireless communication systems interfere with each other?

Wireless Communication systems use open space as the medium for transmitting signals. As a result, there is a huge chance that radio signals from one wireless communication system or network might interfere with other signals. The best example is Bluetooth and Wi-Fi (WLAN).

What is a typical transmission path of a wireless communication system?

A typical transmission path of a Wireless Communication System consists of Encoder, Encryption, Modulation and Multiplexing. The signal from the source is passed through a Source Encoder, which converts the signal in to a suitable form for applying signal processing techniques.

What is the best example of wireless communication?

The best example is Bluetooth and Wi-Fi (WLAN). Both these technologies use the 2.4GHz frequency for communication and when both of these devices are active at the same time, there is a chance of interference. One of the main concerns of wireless communication is Security of the data.
