Before cell phones, people on the go turned to pay phones to drop a dime, maybe a nickel, to call friends and family. A few people --typically well-off professionals such as doctors and lawyers--had car phones. On April 3, 1973, Motorola vice presidents Marty Cooper and John Mitchell went to New York to show off a new type of phone, the likes of which had never been seen before. It was the DynAC, a 30-ounce portable, cordless phone. The main use of cell phones was for business communication. It was convenient for businesses to use cell phones because it allowed employees to leave the office and still be able to conduct things from remote places with ease. It connected employees who generally worked outside the office to their superiors in the office. This ability to communicate with ease leads to quicker decisions and a better quality business. Once more, businesses realized the usefulness of the cell phones and they too began using them, the prices started going down. Once the prices went down and more and more people were using cell phones the advantages in owning one trickled down to the general consumers such as families. Today, cell phones is a widely used technology used in society by all groups of people.
With the growing popularity of hand-held cellular phones, questions have been raised about the safety of being exposed to the radio frequency energy they emit. This rapid expansion has raised health concerns about radio frequency exposure, including possible link between their long-term use to diseases such as brain cancer. But, Indisputable facts are hard to come by in this debate. It has not been clearly established that the electromagnetic emissions from cell phones, can heat up human tissue. The Food and Drug Administration maintain that The available science does not allow us to conclude that mobile phones are absolutely safe, or that they are unsafe. Therefore, more research is needed to clearly establish a linkage between the use of wireless phones and health effects.
