ABSTRACT
The increased popularity of mobile phones among consumers has made the wireless communications industry one of the fastest growing industries ever. At the beginning, the industry concentrated on providing users with telephone access from their cars. The technology, however, was at its early stages, as was evident by the need to use bulky handset radios, which were mounted onto the cars. This, in comparison with the current small handsets, shows the significant progress that has been made in both the system and the radio transmission technologies.
