Abstract

LAS ESTACIONES (BS) BASE EN UN SISTEMA TELEFONICO SIN HILOS, MULTICELULAR ESTAN UNIDAS A TRAVES DE CONDUCCIONES (VL) DE UNION CON UN SISTEMA (KS) DE COMUNICACION -EN PARTICULAR DE UNA INSTALACION DE LUGAR PROXIMO DE TELECOMUNICACION. LAS ESTACIONES (BS) DE BASE ESTAN DISPUESTAS DE TAL MODO A UNA DISTANCIA UNA DE OTRA, QUE LAS INFORMACIONES (SI) EMITIDAS SIN HILOS A PARTIR DE UNA ESTACION (BS) BASE SON RECIBIDAS AL MENOS PARCIALMENTE EN UNA ESTACION (BS) BASE VECINA. TANTO LA INFORMACION SIN HILOS DE LA PRIMERA VEZ, COMO TAMBIEN LA SINCRONIZACION DURANTE EL FUNCIONAMIENTO SE CONTROLA A TRAVES DEL SISTEMA (KS) DE COMUNICACION DE TAL MODO, QUE RESPECTIVAMENTE UNA ESTACION (BS) BASE ESTA SINCRONIZADA SOBRE LAS INFORMACIONES (SI) DE SINCRONIZACION EMITIDAS A PARTIR DE UNA ESTACION (BS) BASE VECINA. CONTRA UNA SINCRONIZACION DE LA ESTACION (BS) BASE A TRAVES DE CONDUCCIONES (VL) DE UNION, SE EVITAN SINCRONIZACION DE HILOS A TRAVES DEL TIEMPO DE DESARROLLO Y DE VELOCIDADES DE ELABORACION DIFERENTES EN LOS EQUIPOS DE SINCRONIZACION REALIZADOS CON LA TECNICA DE CIRCUITO LAS DESVIACIONES DE FASE PROVOCADAS Y CON ELLO ES POSIBLE UNA SINCRONIZACION SOLAPADA AL SISTEMA DE COMUNICACION DE LAS ESTACIONES (BS) DE BASE.
