How Wireless Technology Simplify Our Life

Wireless communication is a term used refer to a transfer of information between two or more points that are NOT connected by any electrical conductor. [1] This technology comes up to answer the limitations of wireline uses. It might allows us to connect wherever possible and much more easily. Why? Let's us take a brief example from the wireless internet connection (Wi-Fi) context in public places such as mall, cafe, school, airport. In Japan and Korea for example, they even have Wi-Fi installed on the bus and traditional market. It means that we can communicate each other easily and usually for free. Not only for communication but also for browsing so we can connect to internet and get the news instantly.

In addition, wireless technology can be used for a multipurpose, simply as wireless computer mice, keyboards, headphones, satellite television, etc. So that, we are no longer need to be troubled by the wires which sometimes could be a little bit annoying. The most common wireless technologies use radio waves. So in radio system, information is sent from one place to another through the air – the transmitter – and picked up in another – the receiver – using an electromagnetic wave to carry it. [3]

If public, especially Indonesian people consciously aware of the benefits of using this technology, this technology will probably become a necessity and the government will be taking part in adding the Wi-Fi facilities, especially in some corners of the city. Of course this technology will continuously develop over the time, one of the technologies that are being developed by Fujitsu is wireless charger, which makes battery-charging process no longer need wires anymore, instead, using a method called magnetic resonance which resembles wireless technology. This technology is able to recharge the battery of device within several meters and 85% more efficient. [2]
