Radio Networks and Location Technologies

The availability of cellular WLAN- networks have become an indispensable part of our daily lives. The steadily growing number of applications imposes new requirements on these systems, ranging from low-data rate and low power-consumption on the one hand to an extremely high transmission capacity and a low latency  at the other. Moreover, radio networks are becoming increasingly complex by added functionality such as the  location-based services.

IMST has extensive experience in all major telecommunication standards such as GSM / GPRS / EDGE, UMTS, LTE, WiFi, Bluetooth and ZigBee, as well as in proprietary approaches  for radio communication. Our participation in numerous national and international research projects allows us to develop new technologies and applications early and to make them available for our customers.

Our know-how is your advantage!
 
Below you will find a selection of our  major research topics in the field of wireless networks and location technologies:

 
 
Car-to-Car (C2C) Communication

IMST is a member of the Car-to-Car (C2C) Communication Consortium and is actively involved in the standardisation process as well as in research projects for C2C- communication applications such as "Network on Wheels" (http://www.network-on-wheels.de/) and "Next Generation Car-2-X Communications'. The vision of the C2C-consortium is to exchange information among vehicles to improve road safety and traffic flow.

UWB and UWB-based Location Technologies


The Ultra-wideband technology enables new applications to communicate with low to very high data bitrates and for the location purposes. When compared to conventional systems, UWB is particularly robust in environments with strong multipath wave propagation, notably inside buildings.

IMST is actively involved in the European regulatory process. Moreover, IMST currently takes part in research projects:
  • “WHYLESS.COM” (IST-2000-25197), „investigating the prospects and  performance of pulse based UWB in communications markets“;
  • “Europcom” (IST-2002-2. 3. 2. 9), utilizing UWB to locate emergency staff in disaster areas; 
  • “Pulsers II” (FP6-027142), demonstrating joint indoor communication and positioning capabilities with an accuracy down to 4 cm.

WLAN Location Technology
 
IMST has developed a configurable software framework, brand-named "i_pos" enabling a fast and easy realization of so-called "location-aware" applications. i_pos is designed for the use of various localisation procedures and methodologies. With the "i_pos"-feature a mobile terminal can determine its own position with reasonable accuracy from the measured signal strength measured by a few WLAN access points.
