چکیده
In this paper, we review 2nd and 3rd generation wireless telephony systems, both in terms of technology and service concepts. We point out some of the technical and service issues that may a ect the functionality and performance from the user point of view. In particular, we focus on one technical and one service concept important for long term success of 3rd generation systems: transmit diversity to increase capacity (quantity),and context-sensitive applications to increase user ac-

Smart antennas can be used to increase the capacity, the link quality and the coverage of existing and future cellular mobile communication networks. Several sophisticated uplink algorithms have been proposed for beamforming and signal detection. But downlink beamforming seems to be the bottleneck of the applicability of adaptive antennas in cellular mobile communication systems. Obviously, a s...
متن کاملIntellectual Property in Broadband Mobile Telecommunications: Predictions on 4G WiMAX
The conflict between intellectual property rights and standardization has become clearly visible with the examples of the second generation (2G) wireless GSM system and the third generation’s (3G) WCDMA and CDMA-2000 systems. Now, on the verge of standardizing fourth generation (4G) systems, the mobile telecommunications industry has become highly sensitive to issues resulting from the ownershi...
متن کاملAccess and Mobility Policy Control at the Network Edge
The fifth generation (5G) system architecture is defined as service-based and the core network functions are described as sets of services accessible through application programming interfaces (API). One of the components of 5G is Multi-access Edge Computing (MEC) which provides the open access to radio network functions through API. Using the mobile edge API third party analytics applications ...
