The multipath propagation of millimeter waves are complicated in the near field. Unknown obstacles in side the area will create different delayed signals compared with the main signal. At 135 Ghz this needs to be tested practically and to be verified with the simulated results. if it goes well then for future we get miniaturized communication systems for our use with big bandwidth and in turn faster communications.
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
