Abstract
A first broadband network divided into sectors and a second narrowband network have collocated cells and a common wide frequency band. The interference produced by the first network on the second network is reduced for a carrier to interference ratio threshold allowable at the reception in the second network. For example, a base station (BSBB,nc) in a given cell (CBB,nc) of the first network attenuates by an attenuation parameter the emission power of each subcarrier which is adjacent to a carrier of one of the groups allocated to preselected cells (CNB,i) of the second network in a sector (Sns) of the given cell and on levels (L0 to LI-1) starting from the given cell (CBB,nc). The attenuation parameter is low for a level close to the given cell.
