Chapter 5 – Analogue systems

Publisher Summary The analogue systems were a major technological achievement for their time. They also established a market that grew much faster than expected. However, there were several drawbacks to the system, which were soon discovered. With the rapidly growing number of subscribers, capacity started to become a major issue. This was why governments around the world started to allocate further spectra this problem in analogue systems. However, it was obvious that a new technology would be needed to overcome the problem in the long run. Another problem was that of security. Not only was it possible to listen to conversations, but it was also possible to clone phones easily. As a result, new systems were developed to ensure that capacity and quality of service targets are met and security levels significantly improve. The resulting systems used digital technology and resulted in migration from the first-generation analogue systems to the second-generation digital ones.
