The location services market is a rapidly growing market that will grow to over $ 8 billion in 2014. It encompasses not only common outdoor GPS positioning but also rapidly advancing indoor positioning which has been developed by many different companies in different forms and with different technologies being used for it. Let us give you a few examples that show you how sophisticated indoor tracking is.
As you walk through the store, mall, or other public place, your smartphone leaves what is called digital breadcrumbs, and various systems collect and store them. This technology is known as wireless fingerprinting. Typically it is used with Wi-Fi frequency band, but other wireless frequencies can be used as well. For example, Homeland Security uses this type of tracking that they call GLANSER. This technology is of great interest to the FBI as it allows people to be tracked in places such as indoors and even underground where no GPS signal is available.

Qubulus developed another technology called the QPS Positioning Engine. Their technology uses radio fingerprinting because every place on the planet has a unique combination of radio waves and is therefore unique. This system can indicate your location up to three meters, whether outside or inside. And of course this technology uses all available frequency ranges for its operation.
The Scottish company Sensewhere has taken a different path. Given that Cell ID technology has an accuracy of about 300 meters and WiFi location is about 80 meters, they have created something new. Together with these two technologies, your server will ping the location of all these smartphones together and in motion, creating a more precise picture (up to 5 meters) of the locations of all these devices within a given building.
The company called CSR has developed its SiRFstarV microchip which can use any available source of location tracking data to determine indoor and outdoor location with high precision (up to 10 meters). In a similar vein, Broadcom has developed its BCM4752 microchip that can find the location of your smartphone outdoors, indoors and even underground, and not just the location itself, but also the ground or height you are currently at. The precision of their microchip is the best among all others on the market, resulting in an accuracy of a few centimeters.
Are you happy to discover such tracking options? Or are you afraid of being persecuted this way? If that's the case, you can prevent your cell phone jammer from tracking you everywhere and protecting your privacy.
