Abstract

For setting up LOS radio links between mobile calling transmitting/receiving stations and other mobile or stationary remote transmitting/receiving stations in a predetermined operating area, especially in the frequency range above 1 GHz, every mobile station is provided with an electronic memory with an associated processor. The memory stores the respective geographical and topographical data of the operating area. Prior to the setting-up of a radio link, the transmission loss between the stations is calculated in accordance with known model calculations on the basis of the geographical and topographical data stored in the memory by inputting into the processor the current location data of the calling station and the remote station.

Claims

1. A method for setting up an LOS radio link between at least one mobile calling transmitting/receiving station and at least one remote transmitting/receiving station, both located in a predetermined operating area, comprising the steps of:

providing the mobile station with an electronic memory and an associated processor;

storing at least geographical or topographical data of the operating area in the memory at the mobile station;

prior to establishing the radio link, based on a current location of the mobile calling station and location of the remote station, calculating a transmission loss between the calling station and the remote station based on at least the geographical or topographical data stored in the memory at the mobile station by inputting into the processor at least the current location of the mobile calling station; and

adjusting operation characteristics of the mobile station in accordance with the calculated transmission loss.
