Is all the wimax links have the back bone network with the micro wave radios. It will be interesting to see how wimax is much better than the 3G and LTE to provide better connections during earthquake.
The backbone of any wireless system is underground optical fibers or copper wires. If an earthquake hits the wires, the wireless system goes down. If this particular incidents that the article is referring is using a mesh network, the wireless system will stay up as long as there is power. Any more information will definitely help to graph the rebostness of WiMax technology.
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.
