Uses for a Wireless Communication System

Many current trends in small businesses use wireless communication in various capacities. Apps for mobile devices, services hosted in the cloud, and the Internet of Things are a few examples (IoT). As a result, we are aware that they are capable of having an effect on businesses and society in general.

The following is a list of five applications for a wireless communication system:

  • Making Calls

Billions of individuals around the globe are subscribed to some kind of cellular communication service. Radio waves are sent from one cell tower to another for this system to function properly. These towers come together to create a network that guides the waves. Therefore, the waves will be triangulated to the call recipients’ phone antennas to locate them. Even though the internet is readily available, it is still necessary for firms to do business by telephone. It is beneficial to customer service as well as sales.


  • Putting Devices Together

  • The technology known as Bluetooth enables users to connect a variety of gadgets. This is accomplished by using radio waves with a short range and low energy. These waves are used by enabled devices to join up with other connected devices and access them.
  • People often link their cellphones to Bluetooth headphones, for instance. Those who are driving and need to make or take calls may do so in a risk-free manner with this choice. In addition, Bluetooth makes it possible to move data from one device to another. It may come from a computer, a tablet, or a smartphone. People who work in offices often have access to this equipment, which allows them to print papers.

Types of Wireless Communication

There are many different kinds of wireless communication technologies, including the following:

  • Infrared (IR) wireless communication

It is used for security control and short- and medium-range communications. Most IR systems work in line-of-sight mode, which means that there can’t be anything between the source (transmitter) and the receiver (receiver) (destination).

Infrared is used in security systems and remote controls for TVs.

Infrared radiation is between microwaves and visible light on the electromagnetic spectrum. 

  • Broadcast Radio

Radio is a service that sends sound through the air as radio waves. It uses a transmitter to send radio waves to an antenna that can receive them. Stations are connected to the radio networks to play the same shows. AM/FM Radio can send up to 2 megabits per second of data over long distances (across countries).

  • Microwave Radio

Voice and data are sent through the air as microwaves, high-frequency radio waves with very short wavelengths. Most of the time, microwave transmission sends messages between stations on the ground and communications systems in space.

  • Communications Satellites

A communication satellite is an artificial device in space that is used to send and receive communications. It works like a radio relay station high above the earth. It can pick up, boost, and reroute analog and digital signals on a certain radio frequency. A signal path transponder is used to send data through a satellite. Most satellites have between 24 and 72 transponders, and each can send and receive up to 155 million bits of data per second. Communication satellites are the best way to send and receive content, including audio and video because they can do so much.
