The StingRay is an IMSI-catcher with both passive (digital analyzer) and energetic (cell-site simulator) capabilities. When working in energetic mode, ItagPro the machine mimics a wireless provider cell tower with the intention to force all close by cell phones and other cellular information units to connect with it. Hand-carried variations are referred to below the trade title KingFish. In active mode, the StingRay will power every compatible cellular machine in a given space to disconnect from its service supplier cell site (e.g., operated by Verizon, AT&T, and many others.) and establish a brand new reference to the StingRay. In most cases, that is completed by having the StingRay broadcast a pilot signal that's both stronger than, or made to look stronger than, the pilot signals being broadcast by respectable cell sites operating in the area. A standard function of all cellular communications protocols is to have the cellular machine connect with the cell site offering the strongest signal. StingRays exploit this function as a method to force temporary connections with cellular units inside a restricted area.

During the means of forcing connections from all compatible cellular devices in a given space, the StingRay operator wants to determine which machine is the specified surveillance target. That is achieved by downloading the IMSI, anti-loss gadget ESN, or other figuring out knowledge from every of the units connected to the StingRay. On this context, the IMSI or equal identifier isn't obtained from the cellular service provider or from every other third-get together. The StingRay downloads this information instantly from the machine using radio waves. In some circumstances, the IMSI or equal identifier of a target gadget is understood to the StingRay operator beforehand. When that is the case, anti-loss gadget the operator will obtain the IMSI or equivalent identifier from every device because it connects to the StingRay. When the downloaded IMSI matches the recognized IMSI of the desired goal, the dragnet will end and the operator will proceed to conduct particular surveillance operations on simply the goal machine.

In other circumstances, the IMSI or equivalent identifier of a goal is not known to the StingRay operator and the goal of the surveillance operation is to determine one or more cellular gadgets being used in a identified area. StingRay can be utilized to obtain the IMSI or equal identifier from each telephone within the protest area. After identifying the telephones, locating and tracking operations can be performed, and anti-loss gadget service suppliers might be pressured to show over account information identifying the phone customers. Cellular telephones are radio transmitters and receivers, ItagPro very like a walkie-talkie. However, the cellphone communicates solely with a repeater inside a close by cell tower installation. At that set up, anti-loss gadget the anti-loss gadget takes in all cell calls in its geographic area and repeats them out to different cell installations which repeat the signals onward to their vacation spot phone (both by radio or landline wires). Radio is used additionally to transmit a caller's voice/data again to the receiver's cellular phone.

The 2-way duplex phone dialog then exists through these interconnections. To make all that work accurately, the system permits computerized increases and decreases in transmitter power (for the person cellphone and for anti-loss gadget the tower repeater, too) in order that only the minimal transmit energy is used to complete and hold the decision lively, "on", and allows the customers to listen to and be heard repeatedly through the conversation. The aim is to carry the decision energetic however use the least quantity of transmitting power, primarily to conserve batteries and be environment friendly. The tower system will sense when a cell phone is not coming in clearly and can order the cellphone to boost transmit power. The user has no control over this boosting; it may happen for a cut up second or for the entire dialog. If the consumer is in a distant location, the power boost may be continuous. Along with carrying voice or data, the cell phone additionally transmits information about itself automatically, and that's boosted or not as the system detects need.
