Abstract: The Institute for Telecommunication Sciences, part of the National Telecommunications has a long-standing program to develop radio channel measurement systems. This paper briefly reviews selected examples of recent measurements, outdoor and indoor, in order to give an overview of the ITS channel sounding program. The examples presented are: 1) diversity gain versus bandwidth experiments for a 1. 92 GHz mobile PCS channel in a suburban neighborhood, 2) transmission loss versus frequency (440 MHz, 1.36 GHz, and 1.92 GHz) for a mobile outdoor channel, and 3) transmission loss and RMS delay spread versus antenna type (LP or CP) in an indoor environment at 5.8 GHz. These experiments demonstrate the flexibility of the system. The important system parameters are wide bandwidths and multiple channels, as required for 3G and 4G wireless systems.
