Mutual relationship of high bit rate radio networks in future telecommunications markets

The background to the study was the introduction of various high-bit-rate radio network technologies, namely third-generation mobile radio (UMTS), wireless local networks (WLAN) and digital terrestrial broadcasting (DVB-T) in 2002/03. At the same time, there are convergence developments on the network, terminal and service level, but also on the level of the affected markets themselves. In this respect, the study assumes a shift in value creation from pure transfer to services and content. In particular, information and entertainment services are expected to gain in importance. Due to different requirements, however, the choice of the appropriate transmission technology is the decisive success factor for future mobile telecommunications services.

The study identifies a significant practical problem in the area of ​​end devices for mobile services. There is a lack of mature and user-friendly end devices for both UMTS and WLAN applications. The large number of extremely different end devices also leads to increased development costs for service providers. On the other hand, however, the targeted development of target group-specific end devices could promote the use of new services. In this respect, the use of standardized operating systems and software platforms is of crucial importance.

Overall, UMTS will become the dominant transmission technology for the mass market of mobile communication (or with a view to the further development of GSM: will remain). In the case of WLAN, the security aspect and roaming between different WLAN networks as well as the associated insufficient degree of standardization are identified as central problems. WLAN has positioned itself primarily as an access technology to the Internet that is tailored to the needs of business customers, whereas an expansion of this market towards private customers is currently only rudimentary. With regard to WiMAX, given the technical properties and the state of development, it cannot be assumed for the time being that this technology will soon make many other networks superfluous. DVB-T, after all, is primarily tailored to the requirements of digital television and therefore only competes with UMTS and WLAN within narrow limits. The regulatory fragmentation and the lack of area coverage in the foreseeable future also limit the spread, the prerequisite for a corresponding competition would be.

In view of the existing variety of technologies, new information and communication services must function on the basis of different network technologies. Open platforms for value-added services are therefore of central importance.
