Comparison of the satellite-to-indoor broadband channel at 1.51 GHz and 5.2 GHz

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. The mobile receiver was mounted on a model train which ran through various rooms. Results are given in terms of received energy, mean delay, root-mean-square delay spread and number of paths depending on various transmitter heights and receiver locations.
