There is no question that cell phones have completely changed the way we live in our world today. The way this process has occurred is by the network of cellular towers. A large number of cells is joined together to form a radio network which establishes what we currently know as a cellular network. Cellular service is provided by a transceiver which is in a fixed location. This would be called a cell site. Another name for this would be a base location. We get radio coverage by cells being joined together. By doing this, service is provided to a large geographic area providing use to many portable devices for communication at any location within the network. As technology has advanced to this stage, allowance for movement from cell to cell during transmission has become a smooth transition.

Over the years, significant changes have been made as to the capabilities within cell phone technology and has improved the ability for communication. These significant changes have divided the history of cell phones into three generations. The second generation 2G mobile phone system emerged in 1990. In the beginning of cell phones, we used the larger version which was called...
