A central station switches the calls and makes connections to regular telephone lines. Cellular telephones have become very popular in the past five years. The market for cellular phones has increased from high profile business man to the average person.

On the Ball State campus, a lot of the students carry cellular phone because the long distance rates can sometimes be cheaper than a traditional long-distance carrier. In the early 1990s, the Federal Communications Commission decided to set aside a huge number of frequencies on the radio spectrum. The FCC hoped new spectrum would start a world of wireless telephones and talking pagers available digitally anywhere in America. These services would operate over networks of tiny low-power radio transmitters sprinkled liberally over the country. There were even plans for these networks to carry digital data, like sports scores or stock quotes delivered to your pager or wristwatch.
