Probes do not send signals, but only the receiving end, which is used to receive signals sent by mobile phones and routers. 2. The acquisition coverage is determined by the signal coverage (signal intensity) of mobile phones and routers. 3. It is suggested that the collection effect is better when the radius is less than 30 meters (pi * 30 * 30 = 2800, i.e. the coverage area of about 2800 square meters). Usually the open space can reach 50-100 meters, and the limit distance is 1000 meters. Acquisition speed: 1. WiFi has 13 channels. Because the signals of mobile phones and routers are distributed in different channels, 13 channels need to be scanned once. Each channel scan takes about 250 milliseconds, that is to say, it takes about 3 seconds (channel switching time). 2. Experience value is that about 80% of scanners can be collected in one round and more than 95% in two rounds, so it is recommended to stay in one place and wait for 1-2 rounds of scanners. Power bank: The advertising machine is powered by 5V, with an average working current of 100mA. Charging power bank with 20000 mAh capacity can work 20000 *80%/100= 160 hours at 80% efficiency. iPhone: The Apple mobile phone only has a random MAC during the probing phase (ie, no WiFi is connected) and the other phases are real MAC. So the probe can grab a random mac if the Apple phone is not connected to the route, and it is a real MAC at other stages. How to identify false MAC: According to the IEEE802.11 specification, the 2nd byte is 0 4 8 C is the normal MAC, as the following MAC 36:CE:00:08:54:EE The second byte is 6, to determine the false MAC Performance: Can collect 2.4G/5G WiFi data Serial port collects MAC address Equipped with Android APP, PC analysis software Precise data collection front end Can be plugged directly into a PC or Android phone Can be used with any device that supports serial ports Mobile and portable, suitable for testing or for external devices Category Parameter Description Wireless parameters Wireless standard 802.11 b/g/n/e/i Frequency range 2.4GHz/5G Hardware parameters CPU Tensilica L106, 32-bit microprocessor Flash external SPI Flash up to 16MB SPI 3 Working voltage 4.4~5.25V (recommended 5V) Working temperature -20~85 Storage temperature Normal temperature Wireless network mode station/softAP/SoftAP+station Software parameters Security mechanism WPA/WPA2 Upgrade firmware Local serial port burning Software development Data reading through the serial port User configuration AT+ instruction set; Android APP Package included: 1 x 2.4G/5G Dual Frequency Serial Port WiFi Probe MAC Collection And Analysis of Passenger Attendance Statistics Module
