Abstract

a presente invenção refere-se a um arranjo de nó de comunicação cdma compre-endendo pelo menos duas unidades de antena separadas espacialmente, pelo me-nos uma unidade de rádio e pelo menos uma unidade de controle. cada unidade de antena tem pelo menos uma área de cobertura correspondente e está conectada à unidade central. a unidade de controle é disposta para alterar as propriedades de transmissão de pelo menos uma primeira unidade de antena, para um terminal de usuário, de modo que mais ou menos potência é transmitida pela primeira unidade de antena em um canal dedicado. a unidade de controle é disposta para monitorar os comandos de malha de controle interno de potência recebidos quando pelo me-nos uma segunda unidade de antena está em comunicação com o terminal de usuário e para determinar se a dita primeira unidade de antena deve iniciar ou parar a comunicação com o terminal de usuário ou continuar como anteriormente, com base em como os comandos de malha de controle interno de potência respondem. a presente descrição também se refere a um método correspondente.
