Yesterday, I talked about wireless communication theories to my friend during we are going to a short trip. We arrived at a lake. It takes more than one hour to be there after I started driving, which is longer than my expectation. I did not put communications in the end of the titles since recently wireless charging is also one another important issues for wireless technology. I also ended by numeric number of 3 since wireless is also kept improving time by time. Twitter is now a popular blog platform, which is sometimes called as one of web 3.0 applications.
