Digital PCS: The Future of Wireless Phone Service

In the past few years the use of mobile phones has increased tremendously. At one time only available to the rich and elite business executives, the luxury of mobile phones can now be used by a wide group of people in different financial situations. Mobile phones are a necessary convenience. They provide instant communication access wherever mobile phone service is offered. There are two options for mobile phone service: analog, and digital PCS. Analog is the more expensive option and has long been the standard for mobile phone service. Digital PCS is the newest form of phone service. It works by converting human speech into software codes and converting them to audio signals before the codes reach the listener. Because it is software based it provides a perfect platform for a variety of advanced wireless features. Digital PCS is the future of mobile phone service and the soon to be de facto standard for wireless phone service.

While these dual band phones are expensive, they provide connections in both analog and digital environments.

Since digital PCS is based on wireless software it allows a robust variety of applications to be used with the service. This allows your phone to expand its capabilities. These applications enable you to be reached at all times. Phones using digital PCS service include caller ID, voice mail, paging, enhanced battery management, and encryption systems. These applications make the phone a powerful communication system.

Caller ID is a feature that alerts you to what number is calling. When your phone rings the display units flashes the incoming number of the caller.
