The geolocation service market is a growing market and will exceed $ 8 billion in 2014. It includes not only ordinary outdoor gps jammer, but also indoor tracking developed by different technology companies. to this end. So let’s describe some examples that will show you how to develop internal controls.
As you browse stores, shopping malls or other public places, your smartphone leaves “digital breadcrumbs” and different systems collect and record them. This technology is called wireless fingerprinting. Usually, it is used with the Wi-Fi band, but other wireless frequencies can be used. For example, the Department of Homeland Security uses this type of tracking called GLANSER. For the FBI, this technology is very interesting because it can place people indoors and other places, even in underground places where GPS signals are not available.
Qubulus created another technology called the QPS positioning engine. Their technology uses fingerprint recognition because each place on the planet has a unique combination of radio waves and is therefore unique in itself. Whether indoors or outdoors, the system can specify your location up to three meters. And, of course, this technique uses all frequency ranges available for its operation.
The Scottish company Sensewhere has taken a different path. Considering that the accuracy of Cell-ID technology is about 300 meters, and the accuracy of Wi-Fi localization is about 80 meters, they have created something new. In addition to these two technologies, their servers can group and locate all of these smartphones in motion, creating more accurate images (up to 5 meters) for all devices in each building.
A company called CSR created its SiRFstarV microchip, which can use all available location tracking data sources to determine indoor and outdoor locations with high accuracy (up to 10 meters). Similarly, Broadcom has also developed the BCM4752 microchip, which allows you to locate your smartphone outdoors, inside or even underground. altitude. Their microchips have the highest accuracy of any other chip on the market, which means a few centimeters of accuracy.
Are you happy to discover the possibility of this follow-up? Or maybe you’re afraid of being constantly tracked in one of these ways? If true, you can prevent your smartphone from tracking your location everywhere and keep it private.
