Hmm, dubious claim here with the "Smart Gateway" >> “The Smart Gateway can learn the availability of the connection to the cloud. After a successful transmission, it will follow that network next time. Otherwise, it will try another one,” says Zhang. Considering, >> Video cameras were spaced every 500 meters along the entire structure. And, >> Yang and his team developed the so-called Smart Gateway to receive data continuously from local sensors and then transmit it to a cloud server using whatever signal was available at the moment. That could include fiber, Ethernet, 2G, 3G, 4G, Wi-Fi, or Zigbee. I'd be interested to see how their network holds up when streaming video to a gateway via Zigbee or video to the cloud over 2G (or even 3G). Considering the system is supposed to go into "continuous stream" mode during a natural disaster or other emergency, I'd guess this is also when the network would collapse. Oof.
