"Technology" Questions
1. What is the difference between analog and digital? Wireless calls can be transmitted using either digital or analog technology. Analog technology transmits voice over airwaves to cellular cell sites, much like a radio broadcast. Digital technology converts voice into groups of electronic bits that are "reassembled" when they reach their destination. Digital transmission allows for greater voice clarity, privacy, advanced telephone features and more capacity. 2. What is TDMA? TDMA, or Time Division Multiple Access, is a wireless digital technology designed to increase channel capacity by separating each wireless call’s signal into pieces and assigning each one to a time slot that lasts a fraction of a second. Using TDMA, a single voice connection can be used to handle up to three wireless phone conversations simultaneously. 3. Why did U.S. Cellular select CDMA 1XRTT as its preferred technology? Many factors impacted the U.S. Cellular's decision, including expanded coverage, enhanced network capacity and the development of next generation products and services. After reviewing all of the other technologies available, U.S. Cellular believes CDMA 1XRTT is the right choice for their customers, as it will provide the best digital service available while at the same time improving their network efficiencies and positioning U.S. Cellular for future growth in terms of data services. 4. What is CDMA 1XRTT? CDMA, or Code Division Multiple Access, is a wireless digital technology in which a unique code is assigned to each word in a conversation. These codes are scrambled and sent over a wireless channel from one wireless phone to another. CDMA’s unique coding structure filters all the codes and reassembles them in the correct order so that significantly more people can carry on a separate conversation on the same frequency without causing interference or static. 1XRTT is the next generation of CDMA technology. 5. What are the benefits of CDMA?
