- Abstract
- Millimeter-wave has been used for high transmission rate fixed communication in line of sight and short range without problems due to multipath reflections. But if it is used for mobile communications, such as WLAN using at 60GHz and 5G using at 28GHz, the delay spread made of multipath reflections limits the transmission rate. The delay spread characteristics were measured in an empty office room with only a partition for nonline of sight (NLOS), and compared the measured and simulated results of ray-tracing method at 60GHz. Finally, we suggested a method to study the delay spread characteristics at 28GHz for 5G service.
