This paper explains that there are various options available for wireless handsets. Many mobile phones, particularly in the United States, are given away by wireless service providers to get customers. Since the providers give the phones away, they want the cheapest implementation consistent with acceptable performance. The highest prices are commanded by the phones with the longest battery life and the smallest overall size. New standards, such as General Packet Radio Service (GPRS) and High Speed Circuit Switched Data (HSCSD), that can handle large amounts of data are beginning to be implemented as standard features in mobile phones.
