What Do you Know About Wireless Technology?

Pictorial Representation Of Connected Computers

What is wireless technology?

The first thought of a layman is that "wireless technology is a kind of technology that involves connection without cables/wires" though the above definition is absolutely correct but wireless technology is more than that.
Proper definition of wireless technology
wireless technology is a kind of technology that uses radio waves to transmit and receive data.
"radio wave is an electromagnetic waveof a frequency between about
10⁴ and 10¹¹ or 10¹² Hz, as used for long-distance communication"

WIRELESS COMMUNICATION
This can be defined as the interactions between a set of computers / interaction between users using a medium (computer/phones)
Types of Wireless Communication Technologies
Wireless communication technology is categorized into different types depending on the distance of communication, the range of data and type of devices used. The following are the different types of wireless communication technologies.

1. RADIO 

Radio communication was one of the first wireless technology developed and it is still in use. The portable multi-channel radios allow the user to communicate over short distances whereas citizen band and maritime radios provide communication services over long distances for truckers and sailors.    Radio Transmission  Mostly radio broadcasts sound through the air as radio waves. Radio has a transmitter which transmits the data in the form of radio signals to the receiver antenna.  To broadcast common programming stations are associated with the radio networks. The broadcast happens either in simulcast or syndication or both the forms. Radio broadcasting may be done via cable FM, and satellites over long distances at up to two megabits/Sec.

 2. CELLULAR

A cellular network uses encrypted radio links, modulated to allow many users to communicate across the single frequency band. As the individual handsets lack significant broadcasting power, the system depends on a network of cellular towers which are capable of triangulating the source of any signal and handing reception duties off to the most suitable antenna.

 3. SATELLITE

Satellite communication is a wireless technology having significant importance across the globe. They have found widespread use in specialized situations.

Satellite Communication System

The devices using satellite technology to communicate directly with the orbiting satellite through radio signals.

This allows users to stay connected virtually from anywhere on the earth. Portable satellite phones and modems have powerful broadcast feature and reception hardware than the cellular devices due to the increased range.

The satellite communication consists of a space segment and a ground segment. When the signal is sent to the satellite through a device, the satellite amplifies the signal and sent it back to the receiver antenna which is located on the earth’s surface. The ground segment consists of a transmitter, receiver and the space segment, which is the satellite itself.

   4. WIFI

Wi-Fi is a low-cost wireless communication technology. A WiFi setup consists of a wireless router which serves a communication hub, linking portable device with an internet connection.This network facilitates connection of many devices depending on the router configuration. These networks are limited in range due to the low power transmission, allowing the user to connect only in the close proximity.
