The Evolution of Wireless Communication

From Analog to Digital & How It's Transformed The World

Technology has steadily transformed our world and wireless communication is one of the newest and quick-growing fields of communication. For the uninitiated, this communication simply refers to the process of information or data transfer without leveraging wires or any physical cable.

In conventional communication units, any type of information or data is transferred from a transmitter to a receiving end, which is also known as the receiver. The distance between these communication objects needs to be limited to facilitate the communication. Even if the distance is a little far off, the quality of communication is visibly disturbed.

Wireless Technology Changes The Games

But such is not the case with wireless communication because at the very crux of this technology you can place the transmission and receiving devices at any corner of the globe and yet enjoy flawless communication. The distance isn’t predefined and can range from a couple of meters to several thousand kilometers. The biggest demonstration of the latter is satellite communication mediums.

If you are reading this article right now, you’ve probably lived in this world of technological delights for quite a while and so you might also be familiar with a bunch of common wireless tools like smartphones, radio broadcasts, WiFi, and Bluetooth, among others.

While all of these communication mediums are equally important, in this article, we will take a closer look at the popular mediums and their various pros and cons.

Two-Way Radios

This is an excellent and perhaps also one of the oldest forms of wireless communication. The working mechanism of two-way radios is quite simple. They send the data to the transmitter via radio waves which are nothing but a form of electromagnetic signals. Because these signals are fairly narrow, you can send radio waves across multiple frequencies. The receiving end is usually the radio antenna that you would find in your two-way radio.

Two-way radios are a fast and effective mode of communication. You can use them to broadcast information and share stuff with your friends or for more professional, security-specific reasons. In addition to two-way radios, wireless signals are also leveraged in broadcast radios. You have probably witnessed radio communication at some point of time in your life. Most radio units or stations host intriguing and engaging programs. Others host informative news, and we also have dedicated radio channels for maritime-specific requirements to ease the communication between the ships and the land.

Did Somebody Say Free?

The biggest and most defining benefit of two-way radios is that you can get them free of cost. The device might cost you something but operating the radio won’t. That means money wouldn’t be a constraint if you are looking for a proper and high-range device for two-way wireless communication.

Having said that, two-way radios come with some caveats as well. One of the biggest among them is the limited range of these radios. Unlike broadcast radios that do not require any specific range between the transmitter and receiver, to operate two-way radios, you need to be at a fairly limited distance or within the same location. Unless you do this, the quality of the call may not be as good. That means even though you can set up these radios anywhere, to use them you need to be in proximity to your partner who has the other radio device.

Cellular Technology

This is yet another excellent means of wireless communication. One of the biggest benefits of cell phone networks is that they are easy to use. Given that cell phones have been around for some time, people are quite familiar with their functionalities. So, when they need to place a call, they know exactly how to proceed with it. The best part about cell phones is that most people can afford them and so placing a long-distance call is no longer a hassle. Depending on whether you have a smartphone or a regular cellphone, you can place your call immediately with a few taps or a press of buttons.

But as with two-way radios, cell phone networks come with cons as well. Even though cellphones are a one-time investment, to keep your preferred network running you need to go for prepaid or postpaid network plans. In some cases, these plans can be expensive thus increasing your overall cost of wireless communication.
