Cellular Phones


The basic concept of cellular phones began in 1947, a type of wireless communication that is most familiar to mobile phones users. It was still huge and bulky before years of evolutions until it became the size of a palm.
Cellular phones which is also known as mobile phones have been very usefull for many of us in a way or another. Today, there are already so many mobile phones suppliers such as Nokia, Sony Erricson, Samsung, LG, Siemens, etc. Mobile phones are becoming more than just a phone, as technology is improving rapidly, new and newer features are available in the phones. These features includes radio, camera, music and video player, 3G, wifi, internet, GPS (Global Positioning System), bluetooth, games, etc.
The enormous increased in the use of wireless mobile telephony improved communication purpose for business and social status, it resulted in an increased number of customers. Businesses were able to order supplies over the phone, helping them to save time and traveling money. The supplier networks expanded without being limited by physical distances, because deals where now made over the phone. More time became available to help customers. It has enabled businesses to respond to customer demands, as providing good service has become a competitive advantage when physical distance is no longer so important. Communications are of high value to society and bring positive effects to economic growth.
However, mobile phones also have negative effects on us. Mobile phone radiation and health concerns have been raised, the exposure of electromagnetic radiation that is emitted by mobile phones is believed to be harmful to human health. It has been claimed that the signals emitted from the mobile phone influences the brain (e.g. headaches). Cellular phone talking while driving leads to a reaction time.
Exposed radiations while talking in mobile phones should give little harm. If mobile phones were very damaging, we would see a lot of brain injury problems already. Saying that, I believe that just as in everything else, a balanced use of mobile phone is appropriate.
