Spatial selection

Spatial selection is a distinctive and most significant characteristic of the McWiLL mobile communication system. Other existing and developed mobile and cellular systems of the 2G – 5G generations so far do not use fully the spatial selection. Solutions that can be found are at most versions of the MIMO modes with the application of a quite reduced antenna base. Actually, MIMO is reduced to the polarization adaptation that can be implemented without a spatial diversity of antennas. The McWiLL system is an exception case: it uses base-station antennas that contain up to 8 elements. It provides an additional antenna-gain increase by up to 9 dB when tracking subscribers by antenna beams. Simultaneous suppression of interfering signals from other subscribers and other external sources as well as the suppression of own radio-signal emission in the direction of these interferences ensures an enhanced communication quality with a reduced transmission level at the same time. The designed system for controlling the antenna patterns makes it possible to implement a wide range of coverage forms by the service management channels thus providing EMC and enhanced environmental characteristics.
