Abstract

<B>DISPOSITIVO DE AUMENTAR A CAPACIDADE EM SISTEMAS DE RADIOCELULAR (MóVEIS E FIXOS)<D>. Processo de dispor uma pluralidade de feixes direcionais (61-64) em um sistema de radiocelular tendo uma pluralidade de antenas cada uma comunicando-se através de uma área de setor respectiva correspondente. Interferência entre setores geograficamente próximos é reduzida pelo processo resultando em um aperfeiçoamento em desempenho de relação de portadora para interferência. Freq³ências de portadora de dois feixes internos transmitidos pela antena uma permuta para dois feixes internos que são transmitidos substancialmente na mesma direção por uma outra antena. Isto resulta em um desempenho de portadora para interferência aperfeiçoado para todos os quatro feixes transmitidos pelas antenas. As técnicas reveladas são aplicáveis a sistemas (tricelulares) excitados no centro e excitados no canto.<B> DEVICE TO INCREASE CAPACITY IN RADIOCELLULAR SYSTEMS (MOBILE AND FIXED) <D>. Process of arranging a plurality of directional beams (61-64) in a radiocellular system having a plurality of antennas each communicating through a corresponding sector area. Interference between geographically close sectors is reduced by the process resulting in an improvement in carrier relationship performance for interference. Carrier frequencies of two internal beams transmitted by the antenna exchange for two internal beams that are transmitted in substantially the same direction by another antenna. This results in improved carrier-to-interference performance for all four beams transmitted by the antennas. The revealed techniques are applicable to (tricellular) systems excited in the center and excited in the corner.
