COMPATIBILITY CONFIGURATION METHOD AND SYSTEM FOR INTERNET OF THINGS DEVICE

Document Type and Number:

WIPO Patent Application WO/2016/183914

Kind Code:

A1

Abstract:

A compatibility configuration method for an Internet of Things device. By arranging an additional energy detection mechanism and a length calibration mechanism with a timer at a digital baseband demodulation part of a Wi-Fi Internet of Things device, when the Wi-Fi Internet of Things device detects a configuration information packet head HT-SIG or a VHT-SIG-B domain from a primary device, the timer and the energy detection mechanism are started, and whether receiving succeeds is judged by taking whether a timing length when channel energy reaches a lower limit coincides with length information in a configuration information packet head HT-SIG or a VHT-SIG-B domain in a higher frequency band mode as a standard; and after the receiving succeeds, transmitted configuration access information sections are acquired by calculating a length difference between received configuration information packets, and the received information sections are combined to obtain configuration access information. In the present invention, instead of directly using configuration information packet length information for configuration, calculation of a packet length difference is adjusted, so that a phenomenon that information packets with the same length are continuously configured can be avoided.
