文章在分析IEEE802.11协议的基础上,提出一种将诱发探测技术和位置指纹法相结合的定位方案。相别于国内外现有对室内定位的研究,该方案不再是终端主动配合协同定位,而是利用数据包捕获和定制发送技术诱发探测得到智能终端的相关信息再与位置指纹法结合,最终实现对保持无线电静默状态的终端定位。该方案可用于对禁止携带智能终端入内的场所进行终端查处、排查工作。论文对方案的技术原理、实施要点、技术难点进行了深入的分析和探讨。
Based on the analysis of IEEE802.11 protocol, this paper proposes a positioning scheme that combines induced detection technology and position fingerprinting. Different from the current domestic and international research on indoor positioning, the solution is no longer the terminal actively cooperate with the co-location, but the use of packet capture and custom send technology induced detection of smart terminals and then the location of the fingerprint information combined with the final Achieve terminal positioning to keep radio silence. The solution can be used for terminal investigation and investigation of places where the smart terminal is forbidden to be carried. Papers on the technical principles of the program, the implementation of key technical difficulties in-depth analysis and discussion.
