2. Location
Positioning using GSM in idle mode and E-OTD in Mobile station
(Enhanced Observed Time Difference)
User location mode (not network based) by using different reference time of neighbour cells
- filter reflections and enhance robustness, reflections are possible to be filtered out by analysis of burst training sequences
- works in idle mode (no additional network load)
- location precision is < 50 m (3 or more antennas)
