Advances in satellite and receiver technology make former denied areas like indoors accessible for satellite based radio services. As a consequence, suitable penetration loss models are of significant importance for service availability planning. Standard penetration loss models ignore the building layout in relation to the transmitter-receiver geometry. Within this paper, we introduce the term entry...
Time Based (TB) localization in terrestrial mobile radio as an augmentation for global navigation satellite systems has recently gained plenty of interests. As an essential tool to develop suitable algorithms for positioning applications in mobile radios, channel models for wireless transmissions have growing significance. Currently there is a lack of investigations on comparing the propagation characteristics...
In order to compare satellite-to-indoor wave propagation channel characteristics between L-band and C-band for satellite navigation applications the German Aerospace Center (DLR) conducted a measurement campaign in June 2008. The measurements were performed at 1.51 GHz for L-band and at 5.2 GHz for C-band with a broadband signal of 100 MHz bandwidth. A mobile crane was used as transmitter platform...
