The StingRay is an IMSI-catcher with each passive (digital analyzer) and ItagPro active (cell-site simulator) capabilities. When operating in lively mode, the machine mimics a wireless carrier cell tower to be able to drive all close by cellphones and other cellular knowledge devices to hook up with it. Hand-carried variations are referred to under the commerce identify KingFish. In lively mode, the StingRay will drive every compatible cellular device in a given space to disconnect from its service provider cell site (e.g., operated by Verizon, AT&T, and so forth.) and establish a brand new reference to the StingRay. Most often, this is accomplished by having the StingRay broadcast a pilot sign that's both stronger than, or made to seem stronger than, the pilot indicators being broadcast by legit cell websites working in the world. A typical perform of all cellular communications protocols is to have the cellular machine hook up with the cell site offering the strongest signal. StingRays exploit this operate as a method to pressure non permanent connections with cellular gadgets inside a limited space.

Throughout the strategy of forcing connections from all suitable cellular units in a given area, the StingRay operator needs to find out which machine is the specified surveillance target. That is accomplished by downloading the IMSI, ESN, or different identifying knowledge from each of the units related to the StingRay. On this context, the IMSI or equivalent identifier is just not obtained from the cellular service provider or from every other third-get together. The StingRay downloads this information directly from the device utilizing radio waves. In some instances, the IMSI or equal identifier of a goal gadget is understood to the StingRay operator beforehand. When this is the case, the operator will obtain the IMSI or equivalent identifier from every device as it connects to the StingRay. When the downloaded IMSI matches the recognized IMSI of the specified goal, the dragnet will end and the operator will proceed to conduct particular surveillance operations on just the goal device.

In other circumstances, the IMSI or equal identifier of a goal is not identified to the StingRay operator portable tracking tag and the goal of the surveillance operation is to establish one or more cellular gadgets being used in a identified space. StingRay can be used to obtain the IMSI or equivalent identifier from each telephone inside the protest space. After identifying the telephones, locating and portable tracking tag operations might be conducted, and repair providers may be forced to turn over account information identifying the cellphone customers. Cellular telephones are radio transmitters and receivers, very similar to a walkie-talkie. However, the cellphone communicates solely with a repeater inside a close by cell tower set up. At that set up, the system takes in all cell calls in its geographic space and repeats them out to other cell installations which repeat the signals onward to their destination telephone (either by radio or landline wires). Radio is used additionally to transmit a caller's voice/knowledge again to the receiver's cellular phone.

The two-method duplex phone conversation then exists by way of these interconnections. To make all that work accurately, the system permits automatic increases and decreases in transmitter power (for the individual cellphone and for the tower repeater, too) in order that only the minimal transmit power is used to finish and hold the call lively, "on", and permits the users to hear and be heard constantly throughout the dialog. The aim is to carry the decision energetic but use the least amount of transmitting energy, mainly to conserve batteries and be efficient. The tower system will sense when a mobile phone is not coming in clearly and can order the cellphone to boost transmit energy. The user has no management over this boosting
