MOBILE RADIO NETWORK WITH CENTRAL CELL BEAMING

摘要

There is an annular network structure with several rings of distance regions and a sector division, the number of which corresponds to the number of cells located around a ring. In the centre there is a base station with higher aerials (3) to beam towards all the cells or for reception from the individual cells. The aerials take the form of strongly focusing directional aerials supplying at least two cells in the same sector radially from the aerial position with the same frequency.
