Abstract

Et trådløst kommunikasjonssystem (100) egnet for å fjernstyre et nedihullsfartøy (105), innbefattende en fartøymontert trådløs transceiver (115) og en trådløs transceiver (110) assosiert med en basestasjon (104). En trådløs kommunikasjonskanal opererer mellom transceiverne (110,115) via elektrisk ledende struktur i en rørledning (102). En prosessor (120) ved en av transceiverne (110, 115) bestemmer en tilgjengelig båndbredde til den trådløse kommunikasjonskanalen basert på en målestokk som indikerer kanalens kvalitet. Prosessoren (120) varierer en rate for dataoverføring over kanalen i respons på verdien av målestokken.
