 Unlike software-based solutions running on the base station controller, Tmonitor devices impose no additional overhead on the core network equipment. Unlike a hardware probe, Tmonitor creates no additional latency and therefore no performance hit.

 The location component can be derived in one of three ways:
-* The first is driven via [[GPS]] data captured by a GPS-enabled mobile handset or other device. Unless the user has a data plan, the GPS location data stays resident on the device. It is not transmitted via channels such as [[SMS]] back to the network operator and thus does not help the oeprator locate the subscriber.

 * The second is through the explicit entry of position by the user via a device-resident application. This may be in combination with GPS data but with additional contextual information provided by the user. This kind of data is transmitted over the data plan but usually bypasses the operator; instead, a third-party site such as [http://www.facebook.com Facebook], [http://www.playfoursquare.com/ FourSquare], [http://www.opentable.com OpenTable], or other such services.
 *The third approach is to derive the position of the handset via timing and signal strength information captured via the mobile network. This can be achieved via such approaches as [http://en.wikipedia.org/wiki/Cell_of_origin_%28telecommunications%29 Cell Identification], [http://en.wikipedia.org/wiki/Time_of_arrival Time of Arrival (TOA)], [http://en.wikipedia.org/wiki/Angle_of_Arrival Angle of Arrival (AOA)], [http://en.wikipedia.org/wiki/U-TDOA Uplink-Time Difference of Arrival (U-TDOA)], [http://www.polariswireless.com/ wireless location signatures], and others.

	It is this third approach that is of interest to service providers. The impetus for the development of such technologies was in large part due to E911 regulations in the USA which compelled mobile service providers to be able to locate a subscriber's physical position to within a certain distance. That being said, the data provided by mobile devices can offer value over and above that of purely meeting E911 requirements. (See the diagram on the right for some examples.) Capturing, aggregating and then reselling that data to other application and service providers offers a means of further monetizing the activity of their subscribers.

−	The challenge for service providers has been to make sense of this flood of data in real-time while not impacting performance or quality of service to the customer.
