"We develop trendsetting, relevant positioning technology that helps people and companies find new approaches on how to locate things."Rönne Reimann, CEO + Founder
Lambda:4 was founded in Hamburg, Germany. 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.
The founder of Lambda:4, Rönne Reimann, started his first tech company in 1987. His last venture was in developing car navigation system technology, which he successfully sold to Harman-Becker Automotive Systems in 2000.
- Radio location, radio navigation, inertial system navigation
- Analysis of complex wave fields
- Measurement of distance and direction with 2.4 GHz technology
- Implementation on low-cost Bluetooth chips
- Security, protection against relay attacks
- Multiple Signal Classification (MUSIC) and other high-resolution spectral methods
- Development and calibration of antenna arrays (diversity, phase measurement)
Use case scenarios
Logistics means optimisation. To this end, it is essential to have a general idea of where something is at a specific time and where it is going. In a complex storage environment for example, it is important that requested goods are found quickly.
Parcel/bulk cargo and container management at airports, ports and for rail traffic also represents a great challenge.
To control this system, accurate tracing and localisation of every single unit in the indoor and outdoor environment becomes essential.
The automotive industry has always been one of the most efficient innovation leaders. In Germany in particular, many new technologies are studied and developed with, amongst other things, an emphasis on new or improved safety systems. Entertainment and ease of use also play an important role. The technology can enable cars to recognise when the key is getting closer and which side of the car the key is on. The car can then open the door/boot accordingly. But that’s not all: the technology not only permits convenience features; even more importantly it can safely detect whether a key is in the car or not, thus enabling truly keyless entry use cases.
Installing a lighting system or in general the localisation/mapping of bigger networks during commissioning or maintenance can be very complex.
In wide-area warehouses or big offices, installations of mesh networks with many nodes and sensors can be very time-consuming (i.e. lighting systems), especially if it is necessary to map the installation. With our technology, all nodes and sensors can map themselves and provide the data to easily create a floor plan during commissioning of the network or during maintenance.
Two main factors come into play that make the realisation of the above-mentioned use cases interesting. First cost and secondly interoperability. One of the most cost-effective standard solutions today is Bluetooth Low Energy. BLE is also available in nearly all Smartphones so it is ideally suited as the core technology for these use cases. For its solutions, Lambda:4 therefore focuses on the 2.4 GHz band and actively takes part in the standardisation process of the Bluetooth SIG.
