Level 5 Indoor Navigation (L5 IN)

The Level 5 Indoor Navigation (L5 IN) research project is funded by the German Federal Ministry of Transport and Digital Infrastructure (BMVI) as part of the 5G Research Regions.

The L5 IN project deals with real-time navigation inside of buildings, using 5G and smartphone sensors. The project demonstrates the feasibility of the transition from outdoor to indoor environments in terms of navigation.

The aim of the Level 5 Indoor Navigation (L5 IN) project is to use the newly introduced 5G technology to demonstrate, based on a research-oriented model project, how indoor navigation systems can function. Such systems were previously only known in the outdoor segment (through GPS) but can now also be integrated into existing smartphone systems within the context of indoor navigation.

The project combines an interdisciplinary approach - based on approaches and methods form geodesy, Building Information Modeling (BIM), software development, computer graphics, machine learning and communication technology to develop a practice-oriented solution approach that can be further adapted by industry and research.

The developed application will later be made available open source for other applications.

Project duration: 10/2019 - 09/2022

Due to its complexity the project includes various research areas. Here some of the topics are briefly presented:

  • Positioning: The positioning of users within an indoor environment works based on smartphone sensors and 5G. In this way indoor navigation is autonomous and possible at any time.
  • San2BIM: The "Scan2BIM" process enables the automated creation of detailed building data models for an up-to-date physical representation of the built environment. A point cloud acquired by laser scanning is further processed to produce an "ACTUAL" representation as BIM.
  • 5G Research Campus HafenCity University: A 5G non-standalone campus network is being built at HCU. A 4G LTE core network is used in combination with a 5G NR access network. The combined frequency spectrum will be used for indoor navigation.
  • Indoor Navigation App: In order to transfer the theoretical research results into practice developed algorithms are implemented in an indoor navigation app. This app can be used to navigate to people, rooms and points of interest in the prototype environment HCU.
