Title
(EN) METHOD OF IMPROVING RF COVERAGE IN A MICROCELL ENVIRONMENT
(FR) PROCEDE PERMETTANT D'AMELIORER LA COUVERTURE RF AVEC DES MICRO-CELLULES
Abstract
(EN)
A radio communication system is provided wherein radio coverage building blocks are used to provide uniform radio coverage to rectilinear floor layouts of buildings. The building blocks are comprised of directional and omnidirectional antennas which are applied to rectangular and irregular layouts. Each building block is divided into multiple small zones and each zone is covered by an antenna. Each antenna in the building block is connected to the same base station through a low loss coupling matrix and all antennas transmit and receive simultaneously. The directional antennas are located near the boundary of the service area. An omnidirectional or directional antenna at the center of the zone may be used to fill the rest of the area.
(FR)
Un système de radiocommunications comporte des modules de couverture radio qui permettent de fournir une couverture radio uniforme à des bâtiments à configuration rectiligne. Ces modules comprennent des antennes directionnelles et omnidirectionnelles qui s'appliquent à des configurations rectangulaires et irrégulières. Chaque module est scindé en de multiples petites zones dont chacune est couverte par une antenne. Chaque antenne d'un module est connectée à la même station de base par une matrice de couplage à faibles pertes et toutes les antennes émettent et reçoivent simultanément. Des antennes directionnelles sont placées près d'une limite de zone de service. On peut recourir à une antenne omnidirectionnele ou directionnelle placée au centre de cette zone pour couvrir le reste de son territoire.
