Abstract

Patente de Invenção: "SISTEMAS E MéTODOS PARA PROVER A CARACTERìSTICA DE PUSH TO TALK PARA SISTEMAS DE COMUNICAçãO SEM FIO". São providos sistemas e métodos para permitir que uma primeira unidade sem fio e uma segunda unidade sem fio compartilhem de um canal único de comunicações, que inclui uma freq³ência de transmissão e uma freq³ência de recepção. Os sistemas e métodos permitem uma transmissão mais espectralmente eficaz de chamadas no modo de Push to talk por um sistema de Acesso Múltiplo por Divisão de Tempo. Os sistemas e métodos incluem designar o canal único de comunicações para a primeira unidade sem fio e a segunda unidade sem fio de modo que a primeira unidade sem fio e a segunda unidade sem fio possam transmitir alternadamente na freq³ência de transmissão, e a primeira unidade sem fio e a segunda unidade sem fio possam monitorar a freq³ência de recepção; receber uma primeira transmissão a partir da primeira unidade sem fio na freq³ência de transmissão; enviar um sinal para a primeira unidade sem fio instruindo a primeira unidade sem fio a parar de transmitir; enviar um sinal para a segunda unidade sem fio que a segunda unidade sem fio pode enviar uma segunda transmissão na freq³ência de transmissão; e receber a segunda transmissão de uma primeira unidade sem fio na freq³ência de transmissão. Os sistemas incluem uma primeira unidade sem fio, uma segunda unidade sem fio e uma estação de base. A primeira unidade sem fio transmite em uma freq³ência de transmissão de um canal de comunicações e monitora uma freq³ência de recepção do canal de comunicações. A segunda unidade sem fio monitora a freq³ência de recepção.
