Abstract
The description relates to a process for improving radio reception on a road system consisting of individual traffic lanes intersecting at any angle via a cellular mobile radio system which comprises a number of adjacent and mutually contacting or partially overlapping radio cells. In the boundary region of each cell there is at least one fixed transmitter with at least one sector aerial which covers at least part of a region of this cell to be supplied with radio frequencies of a channel group. At least one further fixed transmitter is arranged in the transition region with an immediately adjacent cell and at this post there is at least one sector aerial providing the cell to be supplied itself with the same channel group as the fixed transmitter, two or more fixed transmitters transmit simultaneously to a cell and the cells in a linear road structure have a star structure consisting of mutually overlapping ellipsoidal partial areas.
