Progress In Mobile Computing

– continued.
With significant progress in both areas, it is now possible to use standard techniques to the protection of specific targets in the MC, for the protection of the mobile terminal and the air interface. To protect against the installation of potentially harmful applications on mobile devices, digital certificates are used (e.g., security, Symbian OS). Continue to support popular mobile devices, thanks to significantly increased computing power today Hypertext Transfer Protocol Secure for encryption of communication.

To consider, as always in the field of information security, a difference between the actual, objective, and safety of those who perceive the user’s subjective certainty. Here is often the cause when, due to security concerns consumers not to use a quote or management of a company decides against the use of mobile technologies.

Value chain
Within and around the Mobile Computing (MC), a variety of value-added activities take place. It is not only a strong interdependence between these activities is varied, but often are also involved in several different fields of work. In the simple case, this is due to dis-intermediation, that is, extending to neighboring value chain. This could act as a content provider that its contents that is processed and provides even more than a portal.

In other cases, technological, historical, or reasons of market power have led to the diversification of companies. Typical examples are companies that have retail on the high level of recognition as a terminal suppliers operate, their actual core business, but as an infrastructure supplier. This network of relationships affects many processes and can only be recorded if the consideration is applied to the value-added activities in the MC significantly wider than for example in electronic commerce.

Thus, not only the primary activities – are directly contributing to products or services listed in the above definition of the MC into account – but also secondary activities. All in all, great value to identify three areas: the provision of equipment and applications, the provision of wireless communication networks and the provision of services and content for consumers.

Business, revenue and billing models
Business models in the MC can be divided into the basic building blocks (classical) Good, (classical) service, duty, brokerage, disassemble integration, content and context. One way of evaluating business models, the application of the theory> Information with added value and its extension through the concept of mobile added values. Revenues can be achieved from three individual sources of revenue: from the users of an MC-supply, and indirectly related to the users of the MC-tender (i.e., Revenue by third parties), and indirectly related to the MC-range (i.e., under a non-MC-bid).

In addition, revenues can be categorized. To generate direct revenue a functional transaction-> mobile payment is required, in the simplest case by means of payroll through the telephone bill. Often, an MC-is acquired from wireless operators and offered to the customer’s own account. In an age of 2.5G and 3G networks, however, it is also offered on the market by increasing the supply directly through the service provider.

Here, the supplier enters into a direct customer relationship and, by the content and quality of service value willing to pay the customer in addition to transporting data. Between providers and network operators, this is in some form of compensation and provision of value-added effort. Separately, the data volume and the value of the service priced is called a settlement through premium rate; where the customer pays for using the service, which is usually a fixed sum, and which also includes transportation and value. this is called settlement by a fixed price.

Applications
Important applications include :

• MC-applications and services that are offered by mobile, portal and specialized service providers for consumers or for business, especially mobile commerce, search and information services and portals, and entertainment. There are, for example, mobile banking, mobile entertainment and mobile information services (also known as mobile content), mobile marketing and mobile ticketing.
• The application of mobile technologies for the integration of mobile workstations in the electronic chain operational performance, particularly in connection with the improvement of business (mobile business).
