Abstract

A method for adjusting the transmission power of wireless mobile equipments which are distributed in a service area is presented, wherein said service area is divided in a plurality of regions and statistical information about the electromagnetic interference in each region is produced by considering the spatial distribution of the said wireless mobile equipments and obstacles located in said service area using a geographic map and based on the said statistical information for each region a first and a second metric are generated and wherein the transmission power of the said wireless mobile equipments is adjusted using the corresponding first and the second metric according to the particular region the wireless mobile equipment is currently located in. For a given range of transmission the first metric, which is referred to as the Blockage Terrain (BT), is calculated by dividing a first area that would be reached but was shadowed by obstacles by the sum of the said first area and a second area which was not affected by obstacles and the second metric, which is referred to as the Useful Transmission (UT), is calculated by dividing a third area that was not affected by the obstacles and the theoretical area that should be reached if there were no obstacles. The method may be applied in telecommunication equipments, such as sensor networks, cellular phones, tracking and location devives, among others.
