Bluetooth is an open wireless technology for transferring data over shorter distances (up to 100m). It creates Personal Area Networks (PANs). It was created by Sweden based telecom company Ericsson in 1994 which was originally used as a substitute for RS-232 (Serial) data cables. An adhoc group of up to 8 Bluetooth devices (1 master + 7 slaves) is called as a ‘Piconet’. Today Bluetooth is managed by ‘Bluetooth Special Interest Group’. [1, 2]The aim of this mini article is to reveal the secret behind Bluetooth’s logo. The word Bluetooth is an anglicised version of ‘Blatand’ in Danish. It was the epithet of kink Herald I of Denmark and parts of Norway who lived in 10th century. He united Danish tribes into a single kingdom who were apart from each other. Same logic applies in Bluetooth in a way that uniting several communication protocols together forming a universal standard.
Bluetooth logo is a bind rune (aggregation of letters) merging two letters of Younger Futhark alphabet which were initials of King Herald (Hagall + Bjarkan). [1] Refer Figure 2.
