ilities of 3G can be used in combination with success factors according to Chapter 1 and mass market safety needs including medical info according to Figure 2.9. Let us take an example: Many sick children can be at home instead of at hospital, with the same quality of care. The solution is cheaper for the hospital and cheaper for the parents. No traveling is necessary for the parents. There is no need for babysitters for brothers or sisters to the sick child. GPS or a simpler positioning service is used to easily find the patient address when visiting the sick children. Video enhances significantly remote check of the condition of the sick child. Case-book access supports the remote diagnosis/contact. Stockholm and Aland are the first application locations. Similar remote applications could be used for grown-up people and especially old people. See further Chapter 5, sections 5.2-5.5. 2.9 USER PERCEPTION Finding the optimum range of services for a target group is of course not enough. There are at least three areas where user perception comes in. These are pricing, quality of service End-User Needs and Demands and security. There is a kind of relationship between them. The user may for example be able to choose between lower priced, lower quality voice over IP and 'ordinary' telephony. She may also be able to choose between a number of operators/service providers offering a particular service with different quality of service and security at different price levels. This is of course one of the reasons for churn. Quality of service has been important since the beginning of telecommunication, when loudness was a parameter in networks with a heavy loss. The ear was the critical receiver. Today one can add the eye and the computer. See Chapter 7, which is devoted to the subject of quality of service. Security concerns basic human needs, primarily integrity and confidentiality, explained in detail in Chapter 6. The Internet has meant a revolution in communication, but also significant increased security risks. Pricing
