Fundamentals of Wireless Communications Physical Layer Parameters of Common Wireless Systems May 3, 2006 The following table contains measurement results for the root-mean-squared (RMS) delay spread στ for different environments, carrier frequencies, and measurement bandwidths. If you want to dig deeper, a good tutorial about general measurement and modeling aspects is [1], an overview of indoor measurement results is [2]; many European outdoor measurement campaigns are discussed in [3]. environment carrier freq. bandwidth delay spread notes reference (MHz) (MHz) µs urban 910 10 2 Manhattan [4] suburban 1 0.24 5 km Tx–Rx separation 910 10 [5] suburban 2 2 NLOS worst case urban 0.73 910 10 (?)
