If you are like your grandparents, you would have never thought of wireless technology as being possible when you were still a small boy. In fact, it was only in the 20th century when man made a giant leap in technological advancement. There is no doubt that this explosion of knowledge has been exponential. Among these products include wireless technology.
Basically, wireless technology is used to transmit data between two devices without being physically connected. There are invisible wires, as you may call them, but these “wires” are electromagnetic energies being transmitted. Over the years, there have been many different forms of wireless technology, including cellular phones, two-way radios, GPS devices, PDAs, headphones, headsets, keyboards, computer mice, radio receivers, broadcast televisions, cordless phones, and many others.
Obviously, there are many ways that wireless technology can be used. They are the following:
There is a good chance that you own a mobile phone. If not, you have seen one at the very least. Because of mobile phones, or cellular phones, people are now being connected far and wide. According to statistics, there are almost 4 billion mobile phone subscribers worldwide. That figure is more than half of the world’s population. Through the use of radio waves transmitted by signal towers, people can make calls and send text messages.
Wireless data transfer
Wireless data transfer or communication is essential in various industries. Even for personal use, wireless technology has shaped how people interact with each other. Because of the complexity of networking and connectivity, many devices, such as the Iridium 9522b, are employed. As complicated as it may sound, there are some devices that have been created to simplify multiple connections. An example of this is connection manager software, or mobile VPN. Some examples of wireless data communication are the following:
- Wi-Fi – this is the most common type of wireless technology. It is a local area network that is first connected with the use of wires. From there, it is again connected to a wireless router, where the transmission of data can now be performed. Wi-Fi has become the standard wireless technology commonly used in residential and commercial areas.
- Cellular – this type of wireless technology offers the widest area of coverage, ranging from 10-15 miles away from the cellular tower. Because of technological advancement, speed has dramatically increased to support 3G and 4G signals.
- Satellite communication – this wireless technology primarily use satellites orbiting the planet. This is often used when there is no wireless connection available nearby. This is especially useful in the fields of transportation, aviation, military, maritime, and many others.
Modes of wireless technology
Wireless technology works in various ways. This includes radio communication, microwave communication, Infrared, sonic, and electromagnetic induction. It is important to note as well that cordless and wireless connections are different. The former is mostly associated with the use of electrical appliances such as power tools.
These are some of the basic concepts that you need to know about wireless technology. There are more to discover, and further reading is needed to become familiar with this topic.
