Older cellular networks used Time Division Multiple Access
(TDMA) and CDMA Code Division Multiple Access (CDMA) technology to create access
channels for users. These older systems were focused on voice communications and couldn't be well used for data communications. With the GSM or General Subscriber Module service, better data communications are possible and much higher quality voice signals. The goal of the new standards promoted by 3G standards group
include higher spectrum efficiency, better compatibility among different standards and a larger
bandwidth for high-speed data communications. Their goal is to bring the Internet and
multimedia services to the mobile users.
Today, more than 2 billion people worldwide, use GSM Cell phones. This upgrade in telephone services actually provides better service for internet users and voice phone service subscribers. Land lines in many developing nations are either not feasible or are deteriorating and too expensive to repair. So while landline, terrestrial service is diminishing, the new GSM systems are being developed to serve people in these countries.
