According to a recent study by the University of Minnesota, the GSM mobile phone network provides a sufficient amount of location information to allow different third parties to easily access the location of mobile phone users. “We have demonstrated sufficient data from different underlying layers of the common GSM communication stack, which allows an attacker to perform location tests directly on the victim’s phone. We have also shown that these tests can be done carefully without having to call the phone owner Notify them if the PSTN call is interrupted immediately before the end. Www.jammer-mart.com produces various styles of high power gsm jammer.
