Moore's law says that capability of electronic circuits doubles every 18 months. The processor power doubles at present faster than Moore's law, enhancing extended functionality in devices. As seen in Figure 3.49 this is crucial for mobile communication. The basic technological advances can be illustrated with the development of memory cost and microprocessor transistor count. See Figures 3.50 and 3.51. The development offers increased processing power and possibilities for downloading applications and increased storing in the devices. It also offers drawbacks: To combat computer-related crime the police sometimes copy the computer disk of a suspect. With local disks with capacities exceeding 100 Gb this job takes many hours. 3.16 ENABLER OVERVIEW Major support for the development is provided by a number of new standards and other technological development. Understanding Changing Telecommunications - Building a Successful Telecom Business DRAM memory cost decrease Dollars/ megabyte ~$0.05 2005(E) Figure 3.51 Memory cost development Many enabler explanations can be found on the Internet. The list only includes major new or fairly new enablers. The overview is included as a service to the reader. Such list is very hard to keep complete and updated. Two dimensions are used: 1. What happens within the IP area. 2. What happens within the various main network building blocks, according to the segmentation used in this book. Chapter 3 The main developments respond to FP requirements at the network level: IPv6 for an extended/new numbering plan and some other improvements, such as security. Mobile IP for num
