Programming Tips And Tricks

The different types of wireless transmission medium used in computer networks.

This article will discuss the wireless transmission medium that can be used to send or receive data over a computer network.

The process of transferring data over a computer network without the use of wired cables is referred to as wireless transmission.

The most popular wireless transmission methods for sending and receiving data over a network are listed below. Additionally referred to as wireless transmission media types.

Microwave In order to transmit data, microwave signals are used in place of cables. Similar to radio and television signals, microwave signals are transmitted over long distances to improve communication.

In its simplest form, a microwave transmission consists of a transmitter, a receiver, and the environment. In order to send a beam to other antennas that are situated tens of kilometers away, parabolic antennas are typically mounted on towers in microwave communication.

The range that the towers cover increases with their height. When using a tower that is one hundred meters tall, it is possible to have a distance between them of one hundred kilometers. Clear sight lines are necessary for the microwave transmission to send.

Benefits of Microwaves A list of some of the most important advantages of using microwaves is provided below: It is more expensive to use microwave technology than it is to dig trenches for the purpose of laying cables and for maintaining repeaters and cables when cables become damaged for a variety of reasons.

Land acquisition rights are not required when using microwave technology to install and maintain cable lines. Even when traveling over rough terrain, communication is made simpler by the use of microwaves. Microwaves can be used to communicate with one another across oceans.

Disadvantages of Microwave

A list of some of the most important disadvantages of using microwaves is provided below: Microwave information transmission is a risky form of communication. In microwave communication, signals sent from a signal antenna occasionally split into smaller pieces and take slightly different paths to the receiving antenna.

These out-of-phase signals interfere with one another when they combine once more, weakening the original signal. Numerous meteorological events, such as rain, thunderstorms, and others, can interfere with the transmission of microwaves. In microwave technology, the available bandwidth is very constrained. The planning, implementation, and maintenance of microwave links require a sizable financial investment.

Radar Wave Radio frequencies are the information transfer medium in radio wave transmission, a type of transmission.

We all have a good understanding of how radios work, so when certain radio frequencies that are used for direct voice communication are made available to private businesses, those businesses are then able to use those frequencies for their own needs.

A private citizen’s or business user’s license typically gives them access to a range of about 10 miles. For the purpose of transmitting information, including the transmission of audio, video, files, and data, all contemporary radios use sine waves.

It is possible to distinguish between the different radio signals because the sine waves each use have a unique frequency.

Radio setup components The two elements that make up a radio setup are as follows: transmitting device: The transmitter receives a message from the sender and encodes it onto a sine wave before transmitting it over radio waves.

In the context of this discussion, a message can be any type of information, such as voice communication, television images, data for a radio modem, or any other type of data.

The recipient: The receiver picks up the radio waves and uses the sine wave it has picked up to decode the message. Antennas are used during both the radio signal’s transmission and its reception by the transmitter and receiver.

Advantages of Radio Wave

Some of the most important advantages connected with radio waves are listed below: Through the transmission of radio waves, mobility is possible. For the purpose of laying cables and maintaining repeaters and cables in the event that cables become damaged due to a variety of causes, radio waves are more cost-effective than digging trenches.

The ability to avoid acquiring land acquisition rights, which are required for the installation and maintenance of cables, is made possible by radio waves. Communication is facilitated by radio waves even when traversing difficult terrain.

Disadvantages of Radio Wave

Some of the most significant negative effects of radio waves are listed below: A form of communication that is not secure is radio wave communication. Numerous meteorological occurrences, such as lightning and heavy precipitation, have the potential to interfere with radio wave transmission.


Using light of the same wavelength, infrared transmission sends data. Infrared light, which can reflect off surfaces but cannot pass through walls, can spread throughout a room and transmit data through the air. Personal digital assistants (PDAs), such as palm pilots and other handheld electronic devices, are increasingly using infrared transmission. Infrared transmissions are regarded as being secure transmissions.

Infrared Applications in the Real World

There are many uses for infrared transmission in daily life, including: remotes for television a garage door for a car Consider wireless speakers.


Laser transmission needs a clear line of sight. Similar to microwave communication, laser communication is unidirectional but much faster. Each end of the laser transmission needs a laser transmitter and a photo-sensitive receiver. The typical laser transmission between buildings is point-to-point. Weather conditions may interfere with laser transmission.
