Abstract

Et driftssikkert trådløst nett som for eksempel et ringnett som omfatter et hovednav (10) med en sats sendere og en sats mottakere, et flertall områder (12-15) der hvert område omfatter en sender og en mottaker og minst to kommunikasjonsbaner (16-22) for sending av informasjon mellom hovednavet og hvert område. Flere kommunikasjonsbaner er arbeidende baner (16-19) og andre kommunikasjonsbaner virker som beskyttende baner (20-22), med vekslingsanordning for veksling fra en kommunikasjonsbane til en annen. Hver kommunikasjonsbane omfatter minst en toveis trådløs lenk. Dette omfatter videre arbeidende lenker (16-19) mellom navet (10) og minst to av områdene (12-15) og beskyttende lenker (20-22) som forbinder et antall områder med hverandre. Anordningen for veksling av trafikk fra en annen av kommunikasjonsbanene omfatter anordning for veksling av trafikk fra en bane som er dannet av en arbeidende lenk til en bane som er dannet ved kombinasjon av en annen arbeidende lenk med minst en beskyttende lenk eller dannet av et flertall beskyttende lenker, eller fra en bane som er dannet ved kombinasjon av en arbeidende lenk med minst en beskyttende lenk til en bane som er dannet av en annen slik kombinasjon eller dannet av et flertall beskyttende lenker.A reliable wireless network such as a ring network comprising a main hub (10) having a set of transmitters and a set of receivers, a plurality of areas (12-15) each area comprising a transmitter and a receiver and at least two communication paths (16-22). ) for sending information between the main hub and each area. Several communication paths are working paths (16-19) and other communication paths act as protective paths (20-22), with switching device for switching from one communication path to another. Each communication path includes at least one two-way wireless link. This further comprises working links (16-19) between the hub (10) and at least two of the areas (12-15) and protective links (20-22) connecting a number of areas to each other. The device for switching traffic from another of the communication paths comprises means for switching traffic from a path formed by a working link to a path formed by combining another working link with at least one protective link or formed by a plurality of protective links. links, or from a path formed by combining a working link with at least one protective link to a path formed by another such combination or formed by a plurality of protective links.
