摘 要：In the near future, the number of wireless devices will outnumber humans by an order of magnitude, and most of these devices will communicate with each other instead of people. They will not only sense the environment, as most do today, but they will also manipulate it. This closed loop operation will not require the high data rates that today's people-centric networks provide; instead it will require low-latency and high-reliability communication at moderate overall data rates. Currently, high-performance industrial control is one of the few applications that has similar requirements to the IoT of the future. However, control systems exclusively use wired networks because existing wireless systems and standards cannot achieve the latency and reliability required since they are designed for either highthroughput or low-power communication between a small number of terminals.
