Mobile phones' society

According to WirelessGuide (2010),when people think about group of people who always use technology such as mobile phones all time , they will think about 2 kinds of group.

First group is teenager. On the street, in the campus and plaza you can see teenagers with high-tech mobile phones almost implanted their ears. Some group of teenager who come together don't talk to each other because they pay attention to their mobile phones. This reason make the world's changing.

Second group is business people. This kind of people always being able to contact everybody in every time because they are always in emergency situation, even one who is not work. Importance issue can be sole every time that they want because it is easy to contract each other.

In my opinion, I think teenager should use less phone than nowadays because they like to play game and do other activities that is a waste of time but in business people because they use mobile phones to do business and make money.

Mobile phone use affects sleep in teens

According to Excessive mobile phone use affects sleep in teens ScienceDaily (2008), Gaby Badre, MD, PhD, of Sahlgren's Academy in Gothenburg, Sweden do a research about compare two group of people that use mobile phones. First group is a control group (three men, seven women) and second group is the experimental group (three men, eight women). The control group made less than five calls and/or sent five text messages a day, while the experimental group made more than 15 calls and/or sent 15 text messages a day. As a result, young people always use of cell phones (both talking and text messaging) have increased restlessness with more careless lifestyles, more consumption of stimulating beverages, difficulty in falling asleep and disrupted sleep, and more susceptibility to stress and fatigue.

In my opinion, according to the result parents should limit time to use mobile phone for their children. They should buy normal mobile phone.

Number of mobile phone

According to Geneva (2010), the number of using mobile phones always grow up. Right now, there are 4.6 billion mobile phones and at the end of this year , it will increase to five billion people.The number of mobile borad brand subsciptions worldwide also grow up difficult to drop in demand. In rich countries, people like to use advanced technology and handsets. On the other hand, people in developing country like to use health services and banking.

I think, the number of mobile phones always grow up because at this time one person has more than one mobile phone and the price of normal mobile phone is cheaper than in the past. Moreover, parents buy mobile phones for their children so the lower age of people use it.

It's truely more than that. At first, when mobile phones were introduced in the market, the only one main function is contracting each other. But now, mobile phone become more advanced with lots of new function (especcially expensive mobile phones) such as sending picture sms, mms clips, saving a larger number of phonebook entries, with especial tunes and pictures assigned for each caller.
