The Cellular Telephone System

... for another four decades. In 1978, AT&T Bell Laboratories began testing a mobile telephone system based on hexagonal geographical regions, called cells. As the caller's vehicle passed from one cell to another, an automatic switching system would transfer the telephone call to another cell without interruption. The cellular telephone system began nationwide usage in the United States in 1981 (Fascinating).

(CNN) -- In the 19th century, the invention of the telegraph and the telephone forever changed how messages moved around the world. In the 20th century, radio, television, computers and the Internet further revolutionized the near-instantaneous processing and transmission of data. In this day and age where the ability to gather and transmit data is of utmost importance, we see technologies popping up left and right to assist us in ... this task. One of the technologies that gained much popularity is the wireless technology. When we talk about wireless technology, we are not just discussing ce...

... limited system capacity. The breakthrough that addressed this capacity problem was the development of the cellular concept, which allows frequency reuse. Needless to say, the use of wireless communications has increased exponentially since that breakthrough. The evolution of wireless systems can be divided into several stages: 1) the preprevailing stage, 2) the first generation analog system, 3) the second generation digital system, and 4) the third generation system (to be discussed later). The promised services, the required technologies, and the developmental ... portable radio telep...
