Types of Wireless Technology ? It’s types and applications


Introduction of  Wireless Technologies

At the end of the 19th century, the first wireless communication systems were introduced and the technology has significantly been developed over the intervening and subsequent years.Today, the term wireless refers to a variety of devices and technologies ranging from smart phones to laptops, tabs, computers, printers, Bluetooth, etc.The idiom wireless means the  communication or transmission of information over a distance without using  wires, cables or any other electrical conductors.Wireless communication is one of the main mediums of transmission of data or information to other devices.The Communication is set and the information is transmitted through the air, without using any cables, by using electromagnetic waves like radio frequencies, infrared, satellite, etc..

Let’s know about these technologies in brief—



In a communications context, a satellite is a specific wireless receiver/transmitter that is launched by a rocket and placed in orbit around the earth. There are hundreds of satellites currently in operation,it creates a communication channel between a source transmitter and a receiver at different locations on Earth. Communications satellites are used for television, telephone, radio, internet, and military applications.

Applications of Satelite

1. It is used in Radio broadcasting,

2.Amateur radio,

3.Internet access.


What is Wi-Fi Technology

Wi-Fi is the name of a popular wireless networking technology that uses radio waves to provide wireless high-speed Internet and network connections. A common misconception is that the term Wi-Fi is short for “wireless fidelity“,  Wi-Fi is simply a trademarked phrase that means IEEE 802.11x

wireless technology 3-engineeringprayog.comWi-Fi networks have no physical wired connection between transmitter and receiver by using radio frequency (RF) technology – a frequency within the electromagnetic spectrum associated with radio wave propagation. When an RF current is supplied to an antenna, an electromagnetic field is created that then is able to propagate through space.

Applications of Wifi Technology

1.Tether Your Smartphone to Your Computer for Internet Anywhere,

2.Forward Notifications from Your Smartphone to Your PC and many more..


What is Bluetooth technology

Bluetooth is a wireless technology used to transfer data between different electronic devices. The distance of data transmission is small in comparison to other modes of wireless communication. This technology eliminates the use of cords, cables, adapters and permits the electronic devices to communicate wirelessly among each other.wireless technology 4-engineeringprayog.com

Applications of Bluetooth technology

1. It is used in Wireless control of and communication between a mobile phone and a handsfree headset,

2.Wireless control of and communication with iOS and Android device phones, tablets and portable wireless speakers .


What is Zigbee technology ?

ZigBee is a wireless technology developed as an open global standard to address the unique needs of low-cost, low-power wireless M2M networks. The ZigBee standard operates on the IEEE 802.15.4 physical radio specification and operates in unlicensed bands including 2.4 GHz, 900 MHz and 868 MHz.

Applications of Zigbee Technology

1.It is  used in Home automation.

2.Industrial automation.

3.Smart Asset Tracking etc…


What is Wireless Router ?

A wireless router is a device that performs the functions of a router and also includes the functions of a wireless access point. It is used to provide access to the Internet or a private computer network.


wireless technology 6-engineeringprayog.comWireless routers allow multiple computers and other devices, such as smartphones and tablets, to join the same network. While connecting to a router provides access to a local network (LAN), it does not necessarily provide access to the Internet.


What is Wireless Repeater ?

A wireless repeater or wireless range extender takes an existing signal from a wireless router or wireless access point and rebroadcasts it to create a second network.

What is Microwave Band ?

The microwave band is well suited for wireless transmission of signals having large bandwidth between 300MHz and 300GHz in the electromagnetic spectrum.Microwaves travel in straight lines and they will be affected lightly by the troposphere. They don’t require any medium to travel. Metals will reflect these waves totally. Non metals such as glass and particles are partially transparent to these waves.

Applications of Microwave Band

1.Microwaves are suitable for wireless transmission (wireless LAN protocol Ex- Bluetooth) signals having higher bandwidth.

2.Microwaves are commonly used in radar systems where radar uses microwave radiation to detect the range, distance, and other characteristics of sensing devices and mobile broadband applications.


What is Infrared ?

IR wireless is the use of wireless technology in devices or systems that convey data through infrared(IR) radiation. Infrared is electromagnetic energy at a wavelength or wavelengths somewhat longer than those of red light.

1. Used in various military and civilian devices.

 2.Target acquisition, night vision, homing and tracking, surveillance are the major military devices which uses this infrared technology.


What is Radio Technology ?

Radio is the technology of using radio waves to carry information, such as sound, by systematically modulating properties of electromagnetic energy waves transmitted through space, such as their amplitude, frequency, phase, or pulse width.

When radio waves strike an electrical conductor, the oscillating fields induce an alternating current in the conductor.


Mobile phones

A mobile phone is a wireless handheld device that allows users to make calls and send text messages, among other features.
