This is 21ST century, and this is the century of wireless. Wireless technology introduction is our main topic now. We can almost find wireless everywhere.
In our gadget, in some electronic devices, in our audio system, in automobile, or even in our furniture, we can find these devices are already completed with wireless technology.
Well, this thing indicates that people are already tired using wired connection which is often impractical, messy, and has high level of risk.
And those are exactly the reason of why wireless technology has been the new trend among today society. But, apparently, even if the wireless has been massively applied, there are some people still don’t really understand what wireless technology actually is.
So, in order to minimize this technological ignorance, here we provide you the information regarding to the Wireless Technology Introduction.
knowledge Base: Wireless Technology Introduction
1. What do you mean by wireless communication?
Wireless communication is the transfer of information between two or more points that are not connected by an electrical conductor. The most common wireless technologies use radio.
2. What is the wireless transmission?
Wireless transmission is a form of unguided media. Wireless communication involves no physical link established between two or more devices, communicating wirelessly. Wireless signals are spread over in the air and are received and interpreted by appropriate antennas.
Wireless Technology Introduction
Why it should be Wireless Technology Introduction? Well, this is because we think this is really fascinating topic to be discussed. Generally speaking, we can find the application of wireless technology almost in everywhere now, in various kinds and forms of it.
But, based on the fact we found during our concern to this technology, there is only a few percent of people understand perfectly about this technology.
So, we think that this is really important to tell these people, to educate them about the technology that they are using everyday. Besides, the progress of this technology is also massive. There are many new inventories each day. And it will be so wasted if we don’t talk about it, deeply and accurately.
Wireless Technology Definition
Literally meaning, or in our common sense, we can define that wireless technology is a data transferring technology that doesn’t use wire.
In more technological definition, wireless technology / wireless communication is a power or information transfer between two or more devices which are not connected through electrical conductor. But, this term has come through several phases of technological history.
In 1890, the term “wireless” is used to define transmitting and receiving radio technology, with wireless telegraph as the example. But, stepping the year 1920, the term “radio” replaced “wireless” to be used in the exactly the same technology.
While in the modern use, in early 20s, the term “wireless” started to be used to define the technology that doesn’t requires cables. During that time period until now, many people use “wireless” term to refer technology such as Bluetooth, WLAN, NFC, RFID, Zigbee and LTE and many more the types of wireless technology.
Moreover, to complete the Wireless Technology Introduction information, let’s talk about the common way of transmission used in this kind of communication technology. Most wireless technology use radio. They employ radio frequency to communicate to each other.
So, the wired connection is no longer needed. Another way of transmission that used in wireless communication is electromagnetic signal. Here, this communication uses light, electric fields, sound, or even magnetic field to do data transfer.
History of Wireless Technology
The next topic in this Wireless Technology introduction is the history of it. The first usage of wireless technology was started in 1880.
Charles Sumner Tainter and Alexander Graham Bell was the ones that pioneered this trend by inventing the first photophone.
This is the device that uses modulated light beam to conduct audio communication.
This is the very simple wireless transmission. But, this is the pioneer, where similar technology would be developed under the same principle in the following decades.
Move to the early usage of wireless, there were some points that contribute in the development of this technology. For example, David E. Hughes used clockwork keyed transmitter to transfer radio signals in 1878. Then, vibrator magnet was used by Edison to create induction transmission in 1885.
This is where he got the patent for this technology in 1891. Back in the 1888, Heinrich Hertz invented what becomes the basis of wireless technology, which is electromagnetic wave. Hertz described that electromagnetic wave can travel in space through straight lines.
It could be transmitted, and also received by apparatus. This is where the wireless technology started to be developed rapidly by many people in the world.
Wireless Technology Applications
Advantages of wireless technology. Well, due to the high functionality of this technology, there are many applications of it nowadays. As it is stated before, we can find wireless technology in our communication device, home appliances device, entertainment device, automobile, security, and many more.
But, the main application is of course, in the communication aspects. Nowadays, almost every of us use phone, which uses radio waves to transfer signal, to communicate with each other.
By the record, there are more than 4.6 billions of mobile phone usages by the end of 2010. More than that, we also use wireless technology in Data Communication.
We use Wi-Fi, mobile satellite, and even wireless sensor, all of them is the application of wireless technology. In fact, other technology such as cellular data services including CDMA, GSM, 3G, WCDMA, EDGE, HSDPA, LTE, GPRS and others are also classified as wireless too.

Herewith the reference of wireless technology introduction PPT. There are 55 pages which was convert to PDF file. The size of the file about 1019kb. Feel free to download directly at http://homes.ieu.edu.tr/hozcan/CE360/Lect1-Wireless-Introduction.pdf.
With the high number of application, we think it is important for us to understand Wireless technology deeper. This is exactly why we think Wireless Technology Introduction would be the fascinating topic to be discussed.
Finally, at the end of this writing of the wireless technology introduction, we hope that what we write here and what we present you here will bring a lot of goodness. And at the end of the day, these information would be able to update your understanding toward wireless technology, both the new updates and the old ones.
