What is Wireless?


On September 7th, Apple held its 2016 announcement and released the newest Apple product including iPhone 7 and Apple Watch 2. These are all we have expected because it is the time for Apple to introduce its new product. However one expected change is that, the new iPhone 7 will not have a traditional headphone and promote the use of wireless earphone called Airpods. The firm said it had taken "courage" to make this move because people have been used to use their headphone. This is definitely one big change in the cell phone industry.

However what is "wireless" and how can we listen to music or make phone call without having a wire connecting the cell phone and earphone? Lets take a look of what "wireless" is.

Wireless networks are computer networks that are not connected to each others by cables or wires. The use of wireless enables companies to avoid introducing cables into their rooms as connection for the equipment. The basis of computer wireless system is radio wave, an implementation that takes place at the physical level of network structure.It take a wireless transmitter to generate radio waves that contain information or data and a receiver to capture those radio waves, extract the desired signals and then play them.

Wireless technology is rapidly evolving and is playing an increasingly important role in the lives of people around the world. Wireless network enables us to use internet anywhere rather than relying on the cables that restrict us. And it is a a huge leap for the computer science technology. It widens the range of what computer can do. With the benefit of wireless network, scientists are able to develop more advanced technologies that relate to the physical world.

  1. Very nice entry, its crazy to think how wireless technology has evolved so rapidly and now it is ubiquitous. I can only imagine how wireless technology will evolve in the future, I read an article a couple years ago which said we might one day be able to wirelessly charge out phones over wifi (I have no idea how accurate that is I just thought is was a really cool idea).

  2. Wireless technology does enhance the quality of people's lives. However, it also has some drawbacks. For example, wireless network is slower than a wired network and it can be less stable; people need to charge wireless earphone and it can't last as long as high end wired headphones. so, we still need to fix these problems related to wireless technology.

  3. Wireless technology is very useful indeed. With wifi, using computer is more convenient for us. Ming says wireless network is slow, but I think it is fast enough and I believe it will still improve.
