With over 4 billion mobile phones in use, we’ve quickly become accustomed to being able to call our friends, family, and colleagues at the touch of a button.

But it was actually not so long ago that radios and radio technology that is used for cell phones today was but a dream.

Keep reading to discover the history of radio communication and begin to understand just how powerful the technology is.

What Are Radio Waves?

Radio waves are used today to transmit music, conversation, data, pictures, and more, over thousands or millions of miles. While they can reach across countries and continents, they’re also used at home. From baby monitors and cordless phones to garage door openers and TV remotes, radio waves are used all around us.

As amazing as this technology is, it’s actually a relatively simple concept.

Albert Einstein explained radio in 1938 by saying:

You see, wire telegraph is a kind of a very, very long cat. You pull his tail in New York and his head is meowing in Los Angeles. Do you understand this? And radio operates exactly the same way: you send signals here, they receive them there. The only difference is that there is no cat.

The radio waves are sent around the world and when the radio antenna is pulled up, it grabs some of the energy passing by. You choose the station and the electronic circuit in the radio grabs the program that you want to listen to.

History of Radios and Radio Technology

Radio technology is actually relatively new and begins in the late 1800s. Let’s dive into the timeline!

1885 – Electricity Transmission via Electronic Waves

Heinrich Hertz, a German physicist, proved that electric waves could be transmitted and received wirelessly. This was groundbreaking and paved the way for the frequent use of radios that we know today.

1891 – Radio Usage on Ships

Ships were some of the first vessels to implement long-range radio technology. Today we know these radios as wireless telegraphs, and not the radios used to play music or listen to stations.

The implementation of radios on ships allowed for improved safety measures and more reliable shipping methods. Today, we see radio technology used for safety programs all over the world.

Fire departments, for example, implement radio technology for reliable connections in difficult situations. This Kingradios.net article is the ultimate guide to choosing the best fire department radios.

1893 – First Public Radio Demonstration

It wasn’t too long after Heinrich Hertz first proved that the transmission of electric waves was possible that Nikola Tesla was able to wirelessly transmit electromagnetic energy. In 1893 in St. Louis, he publicly demonstrated how the radio worked.

1896 – Radio Is Patented

Shortly after Tesla’s impressive demonstration, Guglielmo Marconi patented his radio apparatus. Just a year later, in 1897, he also established the Wireless Telegraph and Signal Company.

1901 – First Trans-Atlantic Signal

The year 1901 was a big deal because it marked the first trans-Atlantic signal sent. The signal went from Ireland to Canada and demonstrated to the world the vast possibilities that radio technology offered.

1906 – Transmission of Speech and Music

Before transistors, created in 1947, the “Audion” (a triode vacuum tube) was developed in order to amplify radio signals.

1910 – Radio Transmission on Airplanes

Another huge milestone in the history of radios is in 1910 when radio transmission was first successful in airplanes. This marked a new level of safety that would soon help the airline industry become commercialized.

1912 – Federal Regulations Begin

As the radio industry grows and it becomes obvious just how powerful the tools are, the federal government begins regulating American airwaves. Those who were amateur broadcasters needed to be licensed. For radio usage on ships, there needed to be trained operators.

1927 – Federal Radio Commission Established

As more and more people begin to become familiar with radio and the demand for programs and music grows, the American government establishes the Federal Radio Commission.

1947 – Cellular Radio Telephony Developed

In 1947, transistors are developed. These modern pieces of technology are found in almost (if not) every electronic device and they allow for the information age today as we know it.

At this same time, cellular radio technology that we know today was developed at Bell Laboratories. It allowed for call handoff and frequency reuse and opened the door for major telephone usage.

1985 – FCC Allows Spread of Spectrum

At this time, the Federal Communications Commission allowed for broader use of the spectrum, which is the technology used by many of today’s commercial cell services.

1995 – First Commerical Cellular System Launched

Finally, in 1995 the first commercial cellular system was launched by Qual-Comm. It’s clear that from the first days of electric wave transmission, the uses for radio waves have grown exponentially.

Radio Technology Today

Today, radio technology is still widely used for practical devices. From your car radio to your garage door opener, it still is everywhere, however it has changed from its original days.

While in the early days of the radio it was used for music and programs, with the invention of the television and streaming services like Netflix and Hulu we’ve moved away from using radio for entertainment. People turn to Spotify for music and audiobooks and podcasts for nonvisual entertainment.

As much as the radio has changed, its importance in our society has not lessened. The GPS on your phone and in your car uses radio waves. The keyless entry in your car or your home runs on this technology. While machines like MRIs and Xrays don’t use radio waves, they do use different types of wavelengths. Through the development of radio technology, the information age was born.

Antivirus Software Can Make Your Computer More Vulnerable

The core purpose of an antivirus software is to protect your device and the data from malicious programs such as viruses and malware. Using a computer or a smartphone without an antivirus program is considered a crime. Users feel protected and safe.

The beginning of the post-antivirus age

Recently, a team of internet security experts has warned that the antivirus programs are not doing a great job in protecting the data of the users. In fact, in most of the cases, an antivirus program can make your device and data more vulnerable.

The Project Zero team at Google found some major issues in the Symantec and the Norton antivirus programs. The CERT has already issued a warning to the users, and the antivirus companies have been informed of these vulnerabilities but the damage has been done.

No Antivirus Security

Is it safe to use antivirus software?

The question that the users are asking if it is safe to use malware programs?

Apparently, having an antivirus program installed on your machine feels good and protected. This is a general perception but some of the experts don’t use any antivirus software.

Mannan, a professor in Concordia University doesn’t use any antivirus. He hasn’t used any for ages because he doesn’t see any value in them.
The CEO of KnowBe4 is of the view that antiviruses are useless and don’t help in protecting the data anymore.

The best thing you can do is stop using antivirus software. This is what the security experts are doing and this is what they call ‘the post-antivirus age’. Having an antivirus installed on your machine that doesn’t do anything is of no use. Not just that antivirus programs don’t have the capacity to detect and remove viruses but they create loopholes and make your machine insecure.

How to protect your data and device

In today’s post-antivirus age, the best way to protect your machines and data from security breaches is to take precautionary measures. Here is what you should do.

1. Refrain from downloading files and attachments from unknown persons. This is the most common and the primary source of infecting your machine with a virus.
2. Update the operating system regularly. Keep it updated. You should be the first to install the updates from the operating system as these updates keep the machine current and protected.
3. Do not use external storage devices from unknown people. The best practice is to refrain from attaching any storage device with your primary work machine. Ask people to share files via cloud or email as this is a safer route.
4. Do not connect with public Wi-Fi and networks. It is an awesome feeling when your device catches an open network but let this feeling not dominate your senses.
5. Backup your data regularly. This includes everything ranging from photos to videos to important files. Either use cloud storage or an external storage device for the backup.

The best you can do to protect your computer, smartphone and other devices from viruses is to refrain from using antivirus software. This is what the experts do and recommend.
