Mobile Phones -


Mobile Phones are a modern and portable electronic device wich has become a very popular fashion artifact. Even mobile phones started as phones, know they support many additional services, and accesories, such as SMS for text message, email, packet switching for access to the Internet, java gaming, bluetooth, infrared, camera with video recorder.


Mobile phones adquire their signal from base stations that are usually mounted on a tower, pole or building, located throughout populated areas. The phones have a low-power transceiver that transmits voice and data to the nearest cell sites, normally not more than 8 to 13 km away.


An increasing number of countries, particularly in Europe, now have more mobile phones than people. According to recent data, the European Union's in-house statistical office, Luxembourg had the highest mobile phone penetration rate at 158 mobile subscriptions per 100 people (158%), closely followed by Lithuania and Italy. In Hong Kong the penetration rate reached 139.8% of the population in July 2007.Over 50 countries have mobile phone subscription penetration rates higher than that of the population and the Western European average penetration rate was 110% in 2007. The U.S. currently has one of the lowest rates of mobile phone penetrations in the industrialized world at 85%.
There are over five hundred million active mobile phone accounts in China, as of 2007, but the total penetration rate there still stands below 50%.


Warnings about cell phones!

Studies from the Institute of Cancer Research, National Cancer Institute and researchers at the Danish Institute of Cancer Epidemiology in Copenhagen for example showed no link between mobile phone use and cancer.


The use of mobile phones by people who are driving has become increasingly common, either as part of their job, as in the case of delivery drivers who are calling a client, or by commuters who are chatting with a friend. While many drivers have embraced the convenience of using their cellphone while driving, some jurisdictions have made the practice against the law, such as the Canadian provinces of Quebec and Newfoundland and Labrador. Officials from these jurisdictions argue that using a mobile phone while driving is an impediment to vehicle operation that can increase the risk of road traffic accidents.

Men who use mobile phones on a regular basis lose about 30 percent of their active sperm cells. Those who carry their mobile phones in pockets of their pants are putting their potency at great danger. Scientists say that even in sleep mode mobile phones are harmful.[
