Har du nogensinde undret dig over, hvor navnet Bluetooth kommer fra? Og hvorfor har det det m\u00e6rkelige logo, og hvad har alt dette overhovedet med vikingetiden at g\u00f8re? Det er pr\u00e6cis, hvad jeg vil svare p\u00e5 i denne artikel.<\/p>\n\n

Hvor kommer udtrykket Bluetooth fra?<\/h2>\n\n

Okay, lad mig starte med at forklare, hvad Bluetooth er, og hvordan det har f\u00e5et sit navn. I 1996 arbejdede mange teknologivirksomheder p\u00e5 en ny teknologi kaldet kortr\u00e6kkende radiolink. Men problemet var, at de alle havde skabt deres egen standard for den, for eksempel kaldte Intel den Business-RF, og Ericsson kaldte den MC-Link.<\/p>\n\n

Virksomhederne inds\u00e5, at de var n\u00f8dt til at arbejde sammen og skabe en enkelt standard for kortdistanceradio i stedet for at have flere konkurrerende standarder. S\u00e5 virksomhederne oprettede en Special Interest Group (SIG) og holdt et m\u00f8de i Lund p\u00e5 Ericsson-fabrikken i Sverige. Her blev virksomhederne enige om at arbejde sammen, og Special Interest Group (SIG) blev dannet.<\/p>\n\n

En medarbejder fra Intel foreslog, at teknologien skulle have kodenavnet Bluetooth, indtil SIG’s marketinggruppe fandt p\u00e5 et bedre navn til teknologien. Historien om ordet Bluetooth har sine r\u00f8dder i vikingetiden, og Jim Kardach fra Intel fik ideen fra bogen Langskibene af Frans G. Bengtsson og Vikingerne af Gwyn Jones.<\/p>\n\n

Hvorfor blev Bluetooth opfundet?<\/h2>\n\n

Denne teknologi blev opfundet, s\u00e5 enheder kunne udveksle data tr\u00e5dl\u00f8st mellem sig, hvilket endte med at bane vejen for mange af de moderne enheder, vi bruger i dag p\u00e5 daglig basis.<\/p>\n\n

Hvorn\u00e5r blev Bluetooth udgivet?<\/h2>\n\n

I 1999 blev Bluetooth 1.0-specifikationen frigivet, og allerede \u00e5ret efter blev de f\u00f8rste enheder, der brugte denne teknologi, solgt i butikkerne. Nogle af de f\u00f8rste enheder, der brugte Bluetooth, var mobiltelefoner, pc-kort, computermus, b\u00e6rbare computere og headsets.<\/p>\n\n

Hvem var Harald Bl\u00e5tand?<\/h2>\n\n

Men hvem var denne Bluetooth? Jo, Bl\u00e5tand var k\u00e6lenavnet p\u00e5 en dansk konge ved navn Harald Gormsson, som levede i midten af det 10. \u00e5rhundrede i Danmark. Han anses for at v\u00e6re den, der samlede danskerne i \u00e9t rige og gjorde dem kristne, hvilket kan ses p\u00e5 Jellingstenen.<\/p>\n\n

Hvorfor blev han kaldt Bluetooth?<\/h2>\n\n

Der er mange rygter og spekulationer om, hvorfor Harald fik tilnavnet Bl\u00e5tand. Nogle h\u00e6vder, at det var, fordi han havde en d\u00e5rlig tand, andre siger, at han elskede at spise bl\u00e5b\u00e6r eller lakrids. Det kommer m\u00e5ske som en overraskelse for dig, men ingen af disse udsagn er faktisk sande. Faktisk ved vi ikke, hvordan Harald Bl\u00e5tand fik sit \u00f8genavn, men vi har kilder, der n\u00e6vner ham ved det navn.<\/p>\n\n

Den f\u00f8rste omtale af Harald Bl\u00e5tand er i det 11. \u00e5rhundrede, ca. 200 \u00e5r efter hans d\u00f8d. I Roskildekr\u00f8niken, som er skrevet af en ukendt forfatter. Det var det f\u00f8rste fors\u00f8g p\u00e5 at nedskrive Danmarks historie fra 826 til 1157.<\/p>\n\n

Den blev oprindeligt nedskrevet p\u00e5 latin (Chronicon Roskildense), men den blev senere oversat til andre sprog som engelsk og dansk. Det originale manuskript er g\u00e5et tabt, og Roskildekr\u00f8niken findes nu kun i kopier. Det er meget sandsynligt, at Roskildekr\u00f8niken er skrevet af en munk, da den er skrevet p\u00e5 latin. 826 til 1157.<\/p>\n\n

Men Harald kan have haft tilnavnet Bl\u00e5tand, og m\u00e5ske var det s\u00e5dan, folk kaldte ham, n\u00e5r de sad om aftenen og fortalte historier om de store danske konger. Navnet har sandsynligvis overlevet i den mundtlige historie, f\u00f8r det blev skrevet ned \u00e5rhundreder senere.<\/p>\n\n

Hvor kommer Bluetooth-symbolet fra?<\/h2>\n\n

Bluetooth-symbolet har ligesom sit navn sine r\u00f8dder i vikingetiden. Bluetooth-symbolet\/logoet er en kombination af to runer fra den yngre futhark, som var det runealfabet, som vikingerne brugte i vikingetiden.<\/p>\n\n

De brugte Harald Bl\u00e5tands initialer til at skabe det, der kaldes en bindrune, ved at sl\u00e5 hans to initialer sammen. Den nye rune (bindrune) best\u00e5r af bogstavet H (\u16bc) og bogstavet B (\u16d2). \u16bc er kendt som hagall-runen, og \u16d2 er bjarkan-runen. At skabe en bindingsrune var noget, der blev praktiseret i vikingetiden, men det var meget sj\u00e6ldent.<\/p>\n\n
