Wireless Media: Top 7 Types Of Wireless Media

Wireless Media

Wireless media means connection around the word beyound physical connection

In today’s world, we cannot imagine life without communication. The imparting or exchanging of information by speaking, writing, or using some other medium is communication.

Wireless Media

What is wireless media?

Wireless media are also one of the means of communication in which we transmit data and information from one place to another place wirelessly without any use of an electrical conductor as a medium.
Wireless Media

The most common wireless technologies use radio waves. Wireless media carry electromagnetic signals that represent the binary digits of data communications using radio or microwave frequencies.

As a wireless medium means wireless networking medium, it is not restricted to any certain conductors or pathways, as are copper and fibre media provides the greatest mobility options of all media.

Wireless media allows users to access real-time information so they can roam around the company’s space without getting disconnected from the networks.

The number of wireless-enabled devices is continuously increasing and it has become the medium of choice for home networks. As network bandwidth option increases it is quickly gaining in popularity in enterprise networks.

 Areas of concern

In spite of its popularity and so many incredible features it also has some areas to be concerned about,

 Coverage area  

One of the main grounds that should be concerned about wireless media is the coverage area. It works well only in open environments and some construction materials used in buildings and structures, and the local terrain will limit and disturb the effective coverage.


Wireless media is defenceless interference and can be disrupted easily even by common household devices, cordless phones, some type of fluorescent( vividly colourful)  lights, microwave ovens and other wireless communication mediums. 


Network security is a major component of wireless media or network administration. As wireless media doesn’t require a physical strand of media to access so, an unauthorized person can get access easily.

For instance Wi-Fi, the password it uses can often be cracked in a few minutes with a basic laptop computer and widely available software tools.


Following are some of the features of wireless media:

 Increased efficiency

Due to improved data communication in wireless media, it’s helpful to exchange information faster with the clients or customers, partners, and with any other groups or candidates.

 Access and Availability

As wireless media doesn’t need any extra wire of server to get connected you can roam around the company’s space and still get access to the network and it’s rare you are out of touch.


We don’t need to sit in front of the office’s computer all the time to do work, you can still perform productive tasks away from the office.

In today’s scenario, due to this pandemic work from home is the best example of the flexibility of wireless media.


In comparison to wired media, wireless media is less expensive to set it up as it doesn’t need any extra cables and servers to make connections. It automatically reduces the cost.


In case, if there is already existence of any other wireless media or wireless network or technology then there interference in the network exists. This leads to poor communication and in many cases complete loss of wireless communication.

 Transmission speed

In comparison to the wire, transmission wireless is less efficient and in larger networks, the network is usually wired or fibre rather than wireless, because it gets easily disrupted and that leads to poor connection and makes it less convenient.


Wireless transmission is more likely to get attacked by unauthorized users easily and there are more chances of hacking, cracking, and data piracy. So in terms of security, it is not that convenient to use.

Types of wireless media

Types of wireless transmission media used in communication include:

  • Infrared,
  • Bluetooth,
  • Wi-Fi,
  • Radiofrequency,
  • Microwaves
  • and Satellites.


Wireless Media

Infrared sometimes called infrared light, is electromagnetic radiation with wavelengths longer than those of visible light.

It is therefore invisible to human eyes. It is a medium of wireless transmission that sends signals using infrared light waves. It requires a line of sight for the transmission.

For instance, we can take a remote which we use to switch the channels on television. It has a short transmission range and is unable to penetrate walls.

Features Of Infrared

  • They are extremely reliable.
  • It requires minimum power to operate.
  • Communication must be in a straight line.
  • Less coverage area and get easily blocked by walls and people.
  • It has low bandwidth so data transmission is low.
  • It can support so many devices.


Wireless Media

Bluetooth is a wireless technology that connects electronic devices while they are close to each other and it is named after tenth-century Danish king Harald ‘Bluetooth’.

It uses a radio technology which is called frequency-hopping spread spectrum. Bluetooth creates a personal area network (PAN) while transmitting data. It is a standard for the short-range wireless interconnection of mobile phones, computers, and other electronic devices.

It uses short-wavelength radio waves for transmitting files and connecting wireless devices over a short distance. The data transfer rate of Bluetooth technology varies depending on the version. Versions like ( 1.2, 2.0, 3.0 ).

Features OF Bluetooth

  • It has fewer complications.
  • Less power consumption is also one of the features of Bluetooth.
  • It is available at a cheaper rate.
  • In this Bluetooth, up to eight devices can be networked in a piconet.
  • In Bluetooth Signals are Omni-directional.
  • It has low bandwidth as compared to Wi-Fi.
  • It is less secure so it can be hacked.
  • It also has a loose connection in certain conditions.


Wi-Fi stands for wireless fidelity. Nowadays it is very common and almost everyone is familiar with it and it is wireless technology hugged across the globe.

It is a wireless networking technology that allows devices such as computers, mobile devices, and other types of equipment to interface with the internet.

It uses radio waves to provide wireless high-speed network connection and is used for short-distance transmission. It is a family of wireless network protocols, based on the IEEE 802.11 family of standards, which are commonly used for local area networking devices and internet access.

Features Of Wi-Fi

  • It is compatible with almost every operating system, a device like mobile phones, laptops, desktops, etc.
  • We don’t need any extra wires to access the internet on our devices.
  • It has a limited range.
  • Network issue arises with the poor condition of weather.
  • Less secured, can get easily hacked.
  • It has indoor as well as outdoor coverage options.
  • It is less expensive.
  • It has Low range and slower than wired networks.

Radio Frequency

It is the electromagnetic wave frequencies that lie in the range extending from below 3 kilohertz to about 300 gigahertz and that include the frequencies used for communications signals ( as for radio and television broadcasting cell-phone ) or radar signals.

With the help of antennas and transmitters, and RF can be used for various types of wireless broadcasting and communications.

It is measured in units of hertz, which represents the number of cycles per second when a radio wave is transmitted and one hertz means one cycle per second.

Many types of wireless devices make use of RF fields such as Cordless and cell phones, radio and television broadcast stations, etc.


  • It is highly portable- ideal for tour groups.
  • It is easy to install.
  • It requires a low installation cost.
  • It can cover large seating areas.
  • It requires receivers for everyone.
  •  In this radio interference from other services is possible.
  • It is suitable for both indoors and outdoors.


It is a form of electromagnetic radiation with wavelengths ranging from about one meter one millimetre corresponding to frequencies between 300MHZ to 30GHZrespectively.

Microwave is a type of electromagnetic radiation as are radio waves, ultraviolet radiation, x-rays, and gamma rays. Microwaves travel by light-of-sight; unlike lower frequency radio waves they do not diffract around hills.

It is widely used in modern technology, for instance, n point-to-point communication links, wireless networks, microwave radio relay networks, and so on.


  • It supports larger bandwidth.
  • Its installation cost is high.
  • It has a higher data transfer rate as bandwidth is high.
  • Antenna size gets reduced as the frequencies are higher.
  • They are hefty and occupy more space.
  • Electromagnetic interference may occur.
  • It also involves the inherent inefficiency of electric power.


A communication satellite is an artificial satellite that relays and implies radio telecommunication signals via a transponder; it creates a communication channel between a source transmitter and receiver at different locations on earth.

A number of communication satellites owned by the government as well as private organizations have been placed in stationary orbit about 23000 miles above the earth surface.

It accepts data on signals transmitted from one earth station, amplifies them and then retransmit them to another station and forward towards receiving ground station, which is called a downlink.

It is used for long-distance communication. On the basis of distance, it is categorized into three distinct types and is Low earth orbit, medium earth orbit, and Geosynchronous earth orbit.

Features Of Satellite

  • It has a high quality of communication.
  • It has high bandwidth.
  • It works in radio waves.
  • It is not easy to repair and maintain them.
  • It has a high setup cost
  • Ground station sites are easy to install and maintain
  • It spreads over a long distance, it can be cheaper.


In the present world, wireless media of networks is widely used all over the world. As it does not require any physical connection and can cover a huge area.
