- COLLISION MITIGATION IN LOW-POWER FREQUENCY-HOPPING WIDE-AREA NETWORK

摘要

Operating in a predetermined frequency band with receiving gateways and mobile devices with asynchronous local frequency references capable of detecting whether modulated radio signals will collide in frequency within a collision time interval and blanking the signals at the time of collision. Hopping spread-spectrum wireless network for IoT applications. Preferably, the frequency band is sub-divided into sub-bands, and the mobile devices adapt the width of the sub-bands used for transmission based on a synchronization state indicative of a frequency error of a local frequency reference.
