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.
Replay available now: A handful of emerging network technologies are competing to be the preferred wide-area connection for the Internet of Things. All claim lower costs and power use than cellular but none have wide deployment yet. Listen in as proponents of leading contenders make their case to be the metro or national IoT network of the future. Rick Merritt, EE Times Silicon Valley Bureau Chief, moderators this discussion.
