Lambda:4 was founded in Hamburg, Germany. The founder of Lambda:4, Rönne Reimann, started his first tech company in 1987 with various products for home computers. His second venture was in developing car navigation system technology, which he successfully sold to Harman-Becker Automotive Systems in 2000. Lambda:4 was launched with the idea of developing avalanche and SAR rescue systems designed to make alpine sports safer. These positioning technologies have been developed further. Currently they are based on the 2.4 GHz band, enabling reliable and secure positioning for short-range applications such as indoor navigation.
