This paper describes the measurement of wideband radio channel sounding techniques for indoor radio propagation. The system consists of multiple frequency band- switching scheme, which is able to extend the overall sounding bandwidth without changing operation bandwidth of the hardware. It is used for low mobility and high data rate communications. The system of the channel sounding is developed on a universal software radio peripheral (USRP) that employs an orthogonal frequency division multiplexing signal at 2.1902.290 GHz. In each sounding cycling, ten sub band frequency (10 MHz bandwidth) are used to reach an equivalent measurement over a 100-MHz bandwidth, corresponding to 10 ns time delay resolution. The validation test was perform using Vector Network Analyser (VNA). It will be showed variation result of channel impulse response consist of radio channel accuration and resolution between VNA and USRP. At the end of the chapter the proposed system will be used for measuring indoor channel propagation using five scenarios line of sight (LOS) and non-line of sight (NLOS).
