Radio Networks and Location Technologies

With the advent of GSM-and WLAN- networks in our daily lives, they have become indispensable. The steadily growing number of applications demand still for new requirements for such systems, ranging from low-data bitrates and low power-consumption to an extremely high transmission capacity and a low latency  at the same time. Moreover, radio networks are becoming increasingly complex by other functions such as the  location-awareness of such mobile devices.

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 standardization 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 C2C-goal of communications 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. UWB is, compared to conventional systems, particularly robust in environments with strong multipath wave propagation, notably as inside buildings.

IMST is involved in the European regulatory process. IMST is currently involved in various research projects actively:
  • “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" that enables a fast and easy realization of so-called "location-aware" applications. i_pos is designed for the use of various localization procedures and methodologies. With the "i_pos"-feature a mobile terminal can determine from the measured signal strength of a few WLAN access points its own position with quite a good accuracy.
