Title (EN) TDM COMMUNICATION SYSTEM FOR A WIDE AREA SITE AND A PLURALITY OF LOCAL SITES
(FR) SYSTEME DE COMMUNICATION MRT POUR UNE INSTALLATION DE LONGUE PORTEE ET UNE PLURALITE D'INSTALLATIONS LOCALES
Abstract:
(EN) A time division multiplexed system (100) is disclosed in which communication messages among a wide area site (W) and a plurality of substantially scattered local sites (L1-L6) are communicated on a radio frequency channel which is divided into a plurality of time slots (550), wherein at least one of the time slots is further divided into a plurality of sub slots (510-540). Communication units (103) operating in the wide area site (W) communicate communication messages during the time slots, and the communication units (103) operating in the local sites (L1-L6) communicate communication messages during the sub-slots which are assigned to each of the local sites.
(FR) Système à multiplexage à répartition dans le temps (100) dans lequel des messages de communication entre une installation de longue portée (W) et une pluralité d'installations locales considérablement dispersées (L1-L6) sont communiqués sur un radiocanal qui est divisé en une pluralité de tranches de temps (550), au moins une desdites tranches de temps étant elle-même divisée en une pluralité de sous-tranches (510-540). Des unités de communication (103) fonctionnant dans l'installation de longue portée (W) communiquent des messages de communication pendant les tranches de temps, et les unités de communication (103) fonctionnant dans les installations locales (L1-L6) communiquent des messages de communication pendant les sous-tranches assignées à chacune des installations locales.
