The wifi probes can also be used to warn travelers at an airport when it is time to move to the gate based on their actual location on the airport. Also useful for travelers to find a less crowded coach during rush hour. Useful information for the railway company in order to properly distribute material. Nevertheless there are lots of applications of probes that are useful and that do notВ necessarily violate peopleвЂ™s privacy.ДЇor example: you can use it to determine how busy a train coach is at any point in time.

As a result, wifi probing does have a somewhat doubtful reputation. This valuable information can be used for ratherВ doubtfulВ applications like tracking people (without their approval) and hacking.

Finally the mac address can be used to determine the type of device at stake. Furthermore the probes can be used to obtain an indication of the distance of the device from an access point. The client probes contain the globally unique mac address of the device. Access points respond to these probes by providing information required to setup a connection between the device and the access point.

They do so in order to determine if a specific wifi accesspoint is available or to determine which access points are around. Most Wifi devices (like mobile phones) broadcast so called wifi probes once turned on. Interested to know which wifi devices are around? Use a Raspberry Pi to detect devices even if these are not connected to any wifi access pointвЂ¦вЂ¦
