E-1130MIMO Channel Sounder

With mobile communications, the radio waves sent from the transmission antenna are reflected by the land, trees, buildings, etc., and arrive at the reception antenna as many delayed waves coming from different directions. Therefore, correctly identifying the characteristics of the radio propagation paths is very important for communications systems development. Koden’s MIMO channel sounder is a high-resolution radio propagation measurement system for innovative R&D that utilizes Koden’s propriety know-how to achieve high-speed switching of antenna elements and parallel receiving. During measurement, rough measurements are taken in real time while the measurement data is stored in high-capacity data storage units. Using this system makes possible measurement and analysis of dynamic propagation characteristics and contributes to the development of new propagation path models and the advancement of communications systems.
