Abstract

SE PRESENTA UNA RED DE COMUNICACIONES DE DATOS RADIOFONICOS ESPECTROSCOPICOS DIVULGADOS POR SALTOS DE FRECUENCIA. BLOQUES DE MARCA DE TIEMPOS SE TRANSMITEN POR CADA ESTACION BASE CON UN RITMO REGULAR Y CADA BLOQUE DE MARCA DE TIEMPO CONTIENE TODA LA INFORMACION NECESARIA PARA DETERMINAR LA SECUENCIA DE SALTOS DE CANAL, UN CONJUNTO DE POSIBLES CANALES EN USO, Y EL CANAL EN EL CUAL EL BLOQUE DE MARCA ES TRANSMITIDO. LA RECEPCION DE LA MARCA DE TIEMPO RESINCRONIZA UN CRONOMETRO DE PEQUEÑOS ESPACIOS QUE SE USA POR LAS TERMINALES RADIOFONICAS PARA LLEVAR A CABO UN PROTOCOLO DE ACCESO MEDIO CON PEQUEÑOS ESPACIOS HORARIOS SINCRONIZADOS DEFINIDOS. LA ESTACION BASE AL ENLACE RADIO TERMINAL VAGABUNDO ES PARTE DE DOS VIAS. CADA ESTACION BASE RETRANSMITE UN BLOQUE DE FIN DE MENSAJE DURANTE UN PERIODO DE SALTO QUE INDICA QUE NO HAY MAS MENSAJES QUE ENVIAR DURANTE ESE DE SALTO. SI NO HAY MENSAJES FUERA DE RUMBO QUE UNA TERMINAL VAGABUNDA NECESITE ENVIAR, SE PONE SU RECIBIDOR EN UN MODO DE POTENCIA BAJO HASTA QUE EL PROXIMO PERIODO DE SALTO SE ACERQUE. SE PRESENTA TAMBIEN UNA NUEVA ADQUISICION DE LA SECUENCIA DE SALTO PARA UNA ESTACION BASE CERCANA CUANDO EL NIVEL DE SEÑAL RECIBIDO PARA LA ESTACION BASE DE CORRIENTE CAIGA.
