History

A success story since 2004

Lambda:4 has been mostly acting in stealth mode until 2017, when Channel Sounding (at that point it was called HADM - High Accuracy Distance Measurement) was officially proposed as a new technology to the Bluetooth SIG. Here are some milestones in our companies history.

A short demonstration of the current state of our phase based ranging at the Bluetooth SIG meeting can be found here.

2022

Lambda:4 technology is being used in the AvaRange research project where the internal flow behaviour of avalanches is studied. Lambda:4 devices are used to reliably and accurately locate the AvaNode sensors after the avalanche. For more details about AvaRange visit https://www.avarange.org.

2020

Lambda:4 partners with Denso to develop reliable and secure passive entry systems. For more details see the press release

Lambda:4 Beacon prototype Ladybug. First phase based ranging HADM (High accuracy distance measurement) with low cost hardware.

2018

The latest version 5.1 of the Bluetooth Core Spec has been released. It contains two methods for direction finding (AoA / AoD) which have been specified with Lambda:4’s contribution.
