Honeycomb wakeup mechanism-base dual-frequency WiFi module

Abstract

The invention discloses a honeycomb wakeup mechanism-base dual-frequency WiFi module. The honeycomb wakeup mechanism-base dual-frequency WiFi module is characterized in that the honeycomb wakeup mechanism-base dual-frequency WiFi module includes a dual-frequency WiFi module and a 125khz wakeup device assembly which wakes up the dual-frequency WiFi module. When being in a low-power consumption sleep mode, the WiFi module of the invention can monitor 125khz low frequency, once a wireless radio frequency module enters an area covered by a 125khz antenna, the WiFi module can be wakened up and uploads the ID of the 125khz antenna through WiFi. According to the honeycomb wakeup mechanism-base dual-frequency WiFi module of the invention, a honeycomb type antenna is adopted as the wakeup device, and one wakeup device can cover a plurality of areas through a plurality of antennas, and each antenna has a unique ID number; and one set of innovative conflict detection and conflict prevention algorithm is adopted as the wakeup mechanism of the WiFi module, so that the WiFi module can interact with the wakeup device, and therefore, the plurality of antennas on one wakeup device can be supported, and the cost of a whole system can be reduced.

Description

technical field [0001] The invention relates to the technical field of WiFi, in particular to a dual-frequency WiFi module based on a cellular wake-up mechanism. Background technique [0002] WiFi devices have developed rapidly in recent years, especially on smartphones and tablet PCs. Indoor positioning applications based on WiFi or Bluetooth have also been promoted, such as the application of customer flow analysis in shopping malls and the intelligent navigation application of exhibition halls. However, the positioning accuracy of WiFi is greatly affected by the environment, and the density of AP deployment is required to be relatively high. In many occasions, high-precision positioning effects cannot be achieved. For example, it is impossible to determine whether to enter a store or walk outside the store entrance, which affects the accuracy of passenger flow analysis. sex.

However, the positioning accuracy of WiFi is greatly affected by the environment, and the density of AP deployment is required to be relatively high. In many occasions, high-precision positioning effects cannot be achieved. For example, it is impossible to determine whether to enter a store or walk outside the store entrance, which affects the accuracy of passenger flow analysis. sex

At the same time, WiFi or Bluetooth is always working, and the mobile phone consumes a lot of power, which affects the user experience and causes users to turn off WiFi or Bluetooth.
