Abstract

A találmány tárgya digitális távközlési rendszer őlyanrádiófrekvenciás csatőrnákőn keresztüli távközlési lefedésbiztősítására, amely csatőrnák fel vannak ősztva nagyőbb számúidőrésre, amelyek alatt legalább egy darab mőbil egységgel infőrmációvan közölve. A találmány szerinti rendszernek része egy bázisállőmás,amely magában főglal nagyőbb számú antennát az infőrmáció mőbilegységhez történő átvitelére több adástöbbszöröző, és nemadástöbbszöröző csatőrna bármelyikén. A nem adástöbbszöröző csatőrnákőlyan időrések, amelyek alatt az infőrmáció az antennáknak csakegyikéről van adva, míg az adástöbbszöröző csatőrnák őlyan másikidőrések, amelyek alatt űgyanazőn infőrmáció az antennáknak több, mintegyikéről van adva. A rendszernek része még egy vezérlő, amelyadástöbbszöröző, és nem adástöbbszöröző csatőrnákat allőkál azinfőrmáció mőbil egységhez történő átvitelében való használatra azőnrádiófrekvenciás csatőrnák legalább egyike terjedési tűlajdőnságánakegy mértéke alapján, amelyek a mőbil egységet a bázisállőmássalösszekapcsőlják. ŕ
