"We develop trendsetting, relevant positioning technology that helps people and companies find new approaches on how to locate things."

Rönne Reimann, Managing Director & Chairman

About Lambda:4

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.

Core competencies

  • 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.

Delivery periods shall be deemed to be met on timely notification of readiness to ship if the goods cannot be dispatched in time through no fault of Lambda:4.

4.2 Lambda:4 may perform partial deliveries and render partial services if such action would not unreasonably affect the Customer.

5.Transfer of risk

5.1 Unless otherwise expressly agreed in writing, shipment shall always be carried out at the sole risk of the Customer. Any risk shall pass to the Customer as soon as the Delivery Item has been handed over to the person performing the shipment.

5.2 If a shipment is delayed for reasons out of the Customer’s sphere, the risk of accidental deterioration, loss and destruction shall pass to the Customer on notification of Lambda:4’s readiness to ship.

5.3 If Customer defaults in accepting, Lambda:4 shall be entitled to claim refund of any costs associated therewith and the risk of accidental deterioration, loss and destruction shall pass to the Customer.

6.Retention of title

6.1 Lambda:4 retains ownership of all Delivery Items until receipt of full payment of all claims under each existing contract with the Customer.

6.2 While Lambda:4 remains the owner of a Delivery Item, Customer shall not be entitled to pledge or otherwise transfer the Delivery Item as a security. Customer shall immediately inform Lambda:4 in the event of seizure, confiscation, or other disposal by third parties.

7.Services

7.1 Unless expressly agreed to the contrary in writing any services by Lambda:4 and its employees shall be subject to a remuneration.

7.2 The employees of Lambda:4 are not authorized to carry out any work that is not part of Lambda:4’s obligation to deliver.

7.3 Lambda:4 is entitled to use subcontractors to fulfil its service obligations vis-à-vis Customer.

8.Acceptance

8.1 If a Delivery Item is a work product (“Werkleistung”), acceptance shall take place upon completion of such work. The work performed shall be deemed accepted if the Customer has not submitted a written refusal, including reasonable and comprehensive reasons for the refusal, within ten (10) working days.

9.Software programs

9.1 Any software (including but not limited to embedded software and irrespective of whether delivered on a physical media or online) delivered to Customer (hereinafter referred to as “Software”) shall fully remain the property of Lambda:4. No Software, documentation or subsequent upgrade thereof may be disclosed to any third party without the prior written consent by Lambda:4, nor may it be copied or otherwise duplicated, even for the Customer's internal needs with the exception of a single back- up copy for safety purposes.

9.2 Customer is granted a non-exclusive, non-assignable right to use the Software, including any related documentation and updates.

9.3 Software and documentation created and delivered at the Customer's request are the subject of a separate license agreement.

9.4 Unless expressly agreed otherwise in writing Lambda:4 is not obliged to provide to Customer the source code for any Software delivered. Customer is not entitled to reassemble or recompile the Software.

10.Restricted Use

10.1 Customer shall not be entitled to use the Delivery Items for any purpose other than that expressly agreed upon by the Parties or which can be deduced in good faith from product specifications, manuals or any other description of the Delivery Items. Customer shall, in particular, only be entitled to use test equipment, evaluation kits and demo software for test, evaluation or demo purposes and shall not be entitled to sell or otherwise pass on such test equipment, evaluation kits or demo software to third parties or to use them beyond the specified evaluation period.

11.Warranty

11.1 It shall be the Customer's responsibility to check the Delivery Items and notify Lambda:4 in writing of any defects or false or incomplete deliveries without undue delay, however not later than ten (10) working days after handover or, in the case of hidden defects, within ten (10) working days from the date of obtaining knowledge of the defects or the date on which the defects would have been discovered by exercising reasonable investigations. If the Customer fails to notify Lambda:4 in writing in due time, the Delivery Items shall be deemed fully accepted.

11.2 If the Customer claims a Delivery Item to be defective he shall return it to Lambda:4 for examination in its original or an equivalent packaging. Lambda:4 shall remedy any such defects if the warranty claim is valid. It is at Lambda:4’s sole discretion whether Lambda:4 remedies the defect by repair or replacement.

11.3 Customer shall not be entitled to rescind the contract or to reduce the contract price unless it has twice given Lambda:4 a reasonable period to remedy the defect which Lambda:4 has failed to observe, unless setting of such a period to remedy defects is dispensable. In the event of a rescission, Customer shall be liable for any intentional or negligent actions that cause damages to, destruction or loss of the Delivery Items.

11.4 Any rights of the Customer to claim damages or compensation shall be governed exclusively by the provisions in section 12 of these General Terms and Conditions.

11.5 Lambda:4 does not accept any liability for defects in the Delivery Items if such defects are caused by normal wear and tear.

11.6 Any warranty shall be void if operating or maintenance instructions are not observed by the Customer or if changes are made to the Delivery Items unless Customer can show that the defect in question results from another cause.

12.Limited Liability

12.1 The Customer is only entitled to claim damages if Lambda:4 has acted intentionally or with gross negligence or in cases of minor negligence in the event of the loss of life, physical injury and damage to health or a breach of an essential contractual duty (a duty the breach of which puts the fulfilment of the purpose of the contract at risk). However, in case of minor negligence, Lambda:4’s liability shall be limited to typical damages which are foreseeable at the time of the conclusion of the contract.

13.Statute of limitations

13.1 Any claims against Lambda:4 – based on whatever legal ground – shall become time- barred 12 months from the date of delivery to the Customer and in case of tort claims, 12 months from the date the Customer becomes aware or could have become aware of the grounds giving rise to a claim and the liable person.

14.Intellectual property rights, copyright

14.1 Unless expressly agreed to the contrary in writing, each Party shall retain exclusive ownership of any intellectual property that it previously owns and provides for the purposes of any contract falling under these General Terms and Conditions.

14.2 Customer shall respect all copyright and intellectual property owned by Lambda:4. Without restricting the generality of that statement, the Customer shall not reproduce, change or disclose materials supplied by Lambda:4.

15.1.4 to keep separate from all other information all Confidential Information in its possession or control.

15.2 The confidentiality obligation shall not apply to Confidential Information to the extent that it is or was:

15.2.1 already in the possession of the other Party free of any obligation of confidentiality on the date of its disclosure;

15.2.2 in the public domain other than as a result of a breach of this confidentiality obligation;

15.2.3 required to be disclosed:

15.2.3.1 pursuant to applicable law; or

15.2.3.2 in connection with proceedings before a court of competent jurisdiction or under any court order or for the purpose of receiving legal advice, but only to the extent and for the purpose of that disclosure.

15.3 The confidentiality obligations hereunder shall survive any expiration or termination of any contracts concluded between the parties under these General Terms and Conditions.

16.Final provisions

16.1 Any contractual performance is offered and provided by Lambda:4 under the condition that the performance does not conflict with national or international regulations, in particular export control conditions, embargos, or other restrictions. Customer undertakes to provide all information and documents required for export or shipment. Any delays caused by export inspections or approval procedures shall suspend the terms of delivery. If the required approval is not issued or if the contractual performance cannot be approved, the contract shall be deemed as not having been concluded with regard to the affected parts.
