HISTORY OF WIRELESS TECHNOLOGY
Imagine that you have an urgent message to uphold with your friends or family and you have only one landline communication source for the whole village. presently we can’t even imagine that predicament because now we are living in an era of smartphones. Even a running dog has a smartphone(just for an exaggeration). But earlier this isn’t the condition. earlier means the time before the electromagnetic waves had discovered. Previously we are not tangled with the technology of wires or wireless. The story begins a little bit ahead in February 1896 a man came inside the British telegraph authority office. Everyone in the office looked the man suspiciously. But everyone gets wondered about what he showed. He had developed an operational wireless telegraph apparatus. The man was none other than gugilemo macaroni who developed the first wireless telegraph system and also he owned a patent for the invention.
BEFORE MACARONI
Even before macaroni Michael faraday demonstrated electromagnetic induction and built the first direct current generator but this didn’t pave a vivid way for wireless connection. Provided a way to generate electricity. The next big stride was the result of theoretical work by James clerk Maxwell the great Scottish physicist. He published on a” Dynamical theory of the electromagnetic field” in 1865 and in1873.A Treatise on electricity and magnetism, which become what are known Maxwell Equations. These are serious of very difficult differential equations which describes the movement of electromagnetic waves through space. Building on Maxwell work Heinrich hertz in 1887 invented the oscillator and created radio waves
Now, who exactly, should get the credit for the radio is still a subject of debate. Many believe it was, in fact, Nikola tesla who sent information through the air . But I think that Tesla only did an energy transmission between two points and the macaroni was the real idol. He was awarded Nobel prize in 1909
AFTER MACARONI
There have been so many great contributions since then from Edwin Armstrong( who created the FM radio)to Lee De Forest (who invented the electron tube)and Andrew Viterbo (who came up with digital decoding and CDMA
There are so many inventors that made our wireless network dream from virtual to reality.
WHAT IS WIRELESS TECHNOLOGY?
After exploring the history of Wireless technology
Let. Us check out what does the term wireless means?
Wireless technology refers to technology that allows us to communicate without using cables or wires .with this technology communication over a very long distance is feasible, as happening in Nowadays. The rapid use of wireless technology led to the invention of mobile phones. Radio waves are high wavelength waves with less frequency hence it can be captured from very far. Thus we can make use of radio waves in the wireless world.
APPLICATION OF WIRELESS TECHNOLOGY
The application of wireless technology now ranges from wireless data communication in various fields including medicine, military, etc. wireless energy transfers and wireless interface of computer peripherals. Point to point, point to multipoint, broadcasting etc. all are possible and susceptible with the use of wireless.
DIFFERENT TYPE OF WIRELESS COMMUNICATION
There are different types of wireless communication systems such as
• Television and Radio broadcasting
• Satellite communication
• Radar
• Mobile telephone system(cellular communication)
• Global positioning system(GPS)
• Infrared communication
• WLAN(WI-FI)
• Bluetooth
In the present days, the wireless communication system has become an essential part of various types of wireless communication devices that permits the user to communicate
Even from remote operated areas. There are many devices used for wireless communication like mobiles .cordless telephones, GPS, WIFI, Satellite television and wireless computer parts. Current wireless phones include 3 and 4G networks, Bluetooth and Wi-Fi technologies
Anyway, the invention of wireless communication is a boon to us . However, we can’t even think a life without mobiles or other electronic gadgets .This invention made a big leap in the field of communication and networking.
