Claims (18)

1. Fremgangsmåde til etablering af adgang til et medie via en multikanalanordning, hvilket medie omfatter et transmissionssystem med mindst to kanaler (ch1-ch6), på hvilke en meddelelse, som skal transmitteres, omfatter i det mindste en preamble og en header samt en efterfølgende succes kontrol- eller datasektion, hvor kanalerne (ch1-ch6) er kanalgrupperede med henblik på øget båndbredde, og kontrol- eller datasektionen transmitteres under anvendelse af de kanalgrupperede kanaler (ch1-ch6), og hvor meddelelsens preamble og header gentages på alle kanalerne.
2. Fremgangsmåde ifølge krav 1, kendetegnet ved, at preamblen og headeren gentages parallelt på alle kanalerne (ch1-ch6).
3. Fremgangsmåde ifølge krav 1, kendetegnet ved, at de meddelelser, som skal transmitteres, er af typen anmod om afsendelse, RTS, klar til afsendelse, CTS, godkendelse, ACK, eller data, DATA.
4. Fremgangsmåde ifølge et af kravene 1 og 2, kendetegnet ved, at multikanalanordningen fungerer efter standarden IEEE 802.11,802.11 e eller 802.11n med en medieadgangskontrolprotokol, MAC, og i det mindste nogle af de informationselementer, som tilhører MAC-protokollen, gentages på alle kanalerne (ch1-ch6).
5. Fremgangsmåde ifølge et hvilket som helst af kravene 1 til 4, kendetegnet ved, at medieadgangen finder sted i henhold til standarden IEEE 802.11, 802.11e eller 802.11 n, RTS-, CTS- og ACK-kontrolrammerne transmitteres på alle kanalerne (ch1-ch6), og enkeltkanalsanordninger indstiller deres netværksallokeringsvektorer, NAV'er, på grundlag af oplysningerne i RT S/CTS-datapakke rn e.
6. Fremgangsmåde ifølge krav 1, kendetegnet ved trinnene - multikanalanordningens scanning af alle kanaler (ch1-ch6), som skal kontaktes i forbindelse med transmission, - opdagelse af, at en enkelt af disse kanaler (ch1-ch6) er inaktiv, eller at en effektreduktion er på vej fra selve indretningen på denne kanal (ch1-ch6), - multikanalanordningens blokering af denne kanal (ch1-ch6) overfor andre indretninger, - yderligere scanning af de øvrige kanaler (ch1-ch6), som skal kontaktes, og blokering eller reservering deraf efter opdagelse af, at den pågældende kanal (ch1-ch6) er inaktiv, eller at en effektreduktion derpå er på vej.
7. Fremgangsmåde ifølge krav 6, kendetegnet ved, at blokeringen af kanalen (ch1-ch6) udføres af multikanalanordningen og en modtagelsesanordning, som hver udsender en reserveringsmeddelelse.
8. Fremgangsmåde ifølge krav 7, kendetegnet ved, at reserveringsmeddelelsen implementeres i form af RTS- og CTS-skabelon, som transmitteres ved hjælp af følgende trin - multikanalanordningens transmission af en RTS-skabelon på den frie kanal (ch1 -ch6), således at anordningen i området omkring den multikanalanordning, som transmitterer, indstiller deres NAV'er, - modtagelsesanordningens transmission af en CTS-ramme på den frie kanal (ch1-ch6), således at stationer i området omkring modtagestationen indstiller deres NAV'er.
9. Fremgangsmåde ifølge krav 7, kendetegnet ved, at multikanalanordningen udfører sin transmission med kanalgruppering på alle de kanaler (ch1-ch6), som den selv tidligere har blokeret.
10. Fremgangsmåde ifølge krav 6, kendetegnet ved, at blokeringen af kanalen (ch1-ch6) udføres ved multikanalstationens påbegyndelse af transmissionen på den enkelte kanal (ch1-ch6), i hvilket tilfælde transmissionen kan foretages med eller uden en RTS/CTS-mekanisme.
11. Fremgangsmåde ifølge krav 1, kendetegnet ved, at en tredje indretning, som er uafhængig af en sender og modtager, reserverer eller blokerer kanalerne (ch1-ch6) i kanalgruppen for den multikanalanordning, som ønsker at transmittere.

13. Fremgangsmåde ifølge krav 11 eller 12, kendetegnet ved, at i tilfælde af, at individuelle kanaler (ch1-ch6) i kanalgruppen ikke bliver frie samtidigt, forårsager den tredje indretning enten, at (a) én kanal (ch1-ch6) eller individuelle kanaler (ch1-ch6) blokeres, indtil alle kanalerne (ch1-ch6) i kanalgruppen er blevet frie, eller (b) en kanal (ch1-ch6), som er blevet fri, omgående tildeles til den multikanalanordning, som ønsker at transmittere.
14. Fremgangsmåde ifølge et hvilket som helst af kravene 11 til 13, kendetegnet ved, at medieadgangen udføres i henhold til standard IEEE 802.11,802.11e eller 802.11 n, og den tredje indretning er hybridkoordinatoren eller punktkoordinatoren.
