Abstract

A system for locating a mobile communication terminal, the system having an interrogation device, which is configured to solicit a mobile communication terminal of a wireless communication network to establish temporary communication with the interrogation device in an original bandwidth employed for communication between the interrogation device and the mobile communication terminal. Processors configured to isolate the uplink bandwidth of the mobile communication terminal by: configuring the interrogation device to remove a downlink bandwidth, to the wireless communication terminal, from an end of the original bandwidth to create a new downlink bandwidth; calculating an uplink bandwidth at the end of the original bandwidth to be less than the bandwidth removed from the downlink bandwidth; and reconfigure the mobile communication terminal to uplink to the interrogation device on the calculated uplink bandwidth at the end of the original bandwidth. The system further comprising a power detection device (PDD) configured to measure a power of a radio frequency (RF) signal emitted by the mobile communication terminal and having bandwidth filter configured to measure less than a calculated uplink bandwidth and locate the mobile communication terminal.
