The Cell Phone

It’s a cell-phone. Two simple words, but it has changed the type of telecommunication in human’s life. The cell-phone working model depends on the signal towers, just like the relation between bees and honeycomb. The cellular network usually set around the signal tower, and reception cover the area where users accept. In addition, the cell-phone makes distance much less troublesome and bringing people closer, but also bringing some bad affects on our health and public noise. Can you image living without the cell-phone? That would be horrible. Therefore, cell-phone has played an important role in the human’s life and telecommunication’s history.

If we understand the history of cell-phone, and then we can know how important cell-phone is. According to an LA Times article,〝the first cell-phone was used in Sweden by the Swedish police in 1946. 〞The report also said that early cell phone communication technology could be traced back to individuals with special radios that could patch into a phone line via live operator to make a phone call. That was very inconvenient and only a few people could use it, but technology often develops fast. The first commercially automated cellular network (the 1G generation) was launched in Japan by NTT. The NTT network was expanded to cover the whole population of Japan within five years. After that the second generation (2G) and the third generation (3G) cell-phone has developed very quickly during the past fifteen years. Finally, cell-phone become a common tool, everyone need and use it.

Though cell-phone solved the problem of distance and made people closer, but also bringing some bad affects like our health and public noise. Some critics say that a strong cell-phone signal could cause brain cancer. For example, people said we can’t put cell-phone in our pockets for a long time because it would make people sterility in the future. In addition, the cell-phone often makes noise in the public place such as in the classroom, hospital and museum which causes distraction and reduces productivity.

In the internet age, most people communicate through the cell-phone. It's hard to believe that fifteen years ago cell phones were a rarity. Now, the cell-phone is a tool to make people closer, solve the problem of distance and most likely very important in human evolution as well. Through sustainable development maybe cell-phone will be hidden in the human’s body and never leave.
