Abstract
Det er beskrevet et system og fremgangsmåte for feilsikker kommunikasjon av infor- masjon mellom overflateutstyret og nedihullsutstyr. Systemet omfatter to eller flere forsterkere (34, 35, 36) anordnet i en brønn (38) slik at to forsterkere (34, 35) vil motta hvert signal som bærer informasjonen som blir telemetrert. Forsterkeren (35) som ligger lengst borte fra kilden (44) vil omfatte en lageranordning (292) som lagrer informasjo- nen som bæres i signalet. En tidtakeranordning (293) som også er i forsterkeren (35) som er lengst borte fra kilden (44) vil utløse retransmisjonen av informasjonen etter en forutbestemt tidsperiode dersom ikke forsterkeren (35) som ligger lengst borte fra kilden (44) har detektert et signal som bærer informasjonen generert av forsterkeren (34) som ligger nærmere kilden (44).
