10 Important Types of Wireless Communication

wireless communication

We come across different types of wireless communication in our day to day life. In recent years wireless communication has become an essential part of communication devices such as smartphones, laptops, tablets, Zigbee wireless technology, Wi-Fi, satellite, and many more. It allows users and communication devices to transfer data or information from a few meters to hundreds of kilometers without errors.

It seems that I have always been ahead of my time. I had to wait nineteen years before Niagara was harnessed by my system, fifteen years before the basic inventions for wireless which I gave to the world in 1893 were applied universally.

What is Wireless Communication?

Wireless Communication is a method of transmitting information from one place to another without the help of wires, cables, or any other form of an electrical conductor. It uses radio-frequency, IR, microwave, or other types of electromagnetic waves for transmission of data rather than wires, cables, or any other physical medium.

Wireless devices include smartphones, tablets, laptops, computers, printers, Bluetooth, two-way radios, television remote control, GPS receiver, etc. The transmission of information took place from a few meters to hundreds of kilometers based on the requirement. The various forms of wireless communication are satellite, mobile, wireless network, IR, and Bluetooth.

The concept of wireless communication starts at the end of the 19th century and continues to grow significantly over the intervening and subsequent years. For the transfer and display of text in such narrowband devices, a Wireless Markup Language based on XML is used.

There are different types of wireless communication such as IR wireless communication, mobile communication, satellite communication, broadcast radio and TV, Bluetooth, etc. which are discussed below one by one.

Types Of Wireless Communication

Satellite communication is a self-contained wireless communication technology that is widely used around the world to allow users to stay connected from practically anywhere on the planet.

Satellite Communication

These devices employ a radio signal to communicate directly with circling satellites. Over 2000 artificial satellites are currently in use. They are utilized for traditional point-to-point communications, mobile applications, and the distribution of TV and radio programming and can be found in geostationary, Molniya, elliptical, and low Earth orbits.

TV and Radio Broadcasting

Radio communication was the first wireless communication technology developed and still in use today. Radio communication is an example of a Simplex Communication System which means the data can be transmitted in only one direction intended to reach the maximum audience.

It is used to transmit data over short distances as done by Handy multichannel whereas Citizen’s band and maritime radios provide services for truckers and sailors. In this technology, data are transmitted over the radio waves in the form of a radio signal from transmitter to a receiving antenna. The frequency that the radio system uses ranges from 10KHz to 1GHz and the frequency is regulated by the Federal Communication Commission.

In the same way television broadcast the signal over the radio waves from the earth-based transmitter to TV receivers having an antenna. For example, 92.7 BIG FM broadcasts its signal at a frequency of 92.7 MHz that means the transmitter at the station is periodic at a frequency of 92,700,000 cycles/second.

Mobile Telephone Communication System

A mobile telephone communication system is one of the most popular and commonly used wireless communication systems worldwide. They are used for mobile telecommunications over a cellular network(1G, 2G, 3G, 4G and 5G) for transmitting and receiving voice, video, and data.

The communication made through mobile phones is full-duplex that is communication can be made at the same time from both ends.

As radio waves are used for transmitting and receiving the information they allow a significant degree of mobility from a few meters to hundreds of kilometers.

Nowadays mobile phones are not only the means of making a call as they are integrated with many other facilities such as Wi-Fi, Bluetooth, Gps, and FM radio.

Infrared(IR) Communication

Infrared communication is another important form of wireless communication technology. It is used for device communication over short ranges as their waves of the electromagnetic spectrum cannot travel long distances.

IR are commonly found in remote control of televisions, computers, cars, audio equipment, blu-ray player, and many others. The maximum coverage that the IR source gives is about 10m.

Furthermore, IR light-emitting diodes(LED) are used to transmit the IR signal.

Global Positioning System (GPS)

GPS stands for Global Positioning System which is used to locate the ground positioning of an object using four satellites. This technology was first used in 1960s by the United States military and to the general public over the next few decades.

GPS are also used for mapping and surveying, navigate airplanes, security, monitoring object and personal movement and timing(bringing precise timing to the world).


Bluetooth is a short-range wireless communication system. The major function of the Bluetooth is to transfer data, voice, and video between wireless devices equipped with Bluetooth devices.

For example, mobile phones connected to hands-free earpieces, laptops with wireless keyboard and mouse are all possible with the help of Bluetooth devices.

The transmission range is about 10 meters which is very useful in connecting home appliances to transfer information.


A pager is an old-fashioned wireless telecommunication device that provides information in the form of messages. Previously they can be only for receiving messages that mean it a simplex system but nowadays two-way paging messages using an internal transmitter.

The development of pagers began in the 1950s and1960s and gains popularity in the 1980s. Each pager has a unique identification sequence called a Channel Access Protocol(CAP) code which is used to alert the user to give information.

There are five basic types of pager beeper, Voice/tone, Numeric, Alphanumeric, two-way. This system has large coverage areas which are beneficial in man-made and natural disaster to alert the concerned department.


Today, there are a number of wireless communication alternatives. We learned that wireless systems convey signals or data using radio frequency, infrared, microwave, or other types of electromagnetic or acoustic waves rather than wires, cables, or fiber optics.
Despite the fact that the fundamental architecture of these communication technologies differs, they all lack a physical or connected connection between their respective devices to initiate and execute communication.
