6- Localization System of Independent Cellular Telephony.

Objetive: Learn with relative precision the location of a cell phone with the possibility to intercept the communications that are generated in the same one.

Description: The operation is based on the location of receivers in strategic places of each cellular cell. The receivers, besides having the possibility of decoding the control channel and intercepting the different communications, have additional directional receiver antennas which allows to calculate approximately the position of the cell phone through a joint triangulation.

The data are processed and transmitted to a central unit that is in charge of the joint triangulation and it's the one that has the total control of the system. The user´s interface runs over that central unit. The third element that composes this system is a mobile receiver for the approach to the cell equipment achieving to decrease the error of search.
 

7- Location and interception system for cellular telephony mobiles
at national level.

The system allows to carry out the reception and location of the mobile units from a surveillance center destined for that purpose . The performance is based on the triangulation, in environments of great urban density, by means of the measurement of the channels of control of the businesses suppliers.

OBSERVATIONS: this system will be able to be acquired only by government agencies and its implementation is carried out agreeing to the infrastructure of the suppliers companies whose contribution should be obtained for the contracting government agency.

Basic plan: Each mobile is taken by a Radio Base (normally the most nearby one). Once the radio base´s position is known, the position of the nearby radio bases, the density of distribution and a referenced cartoghaphic map, the information is crossed and processed by an algorithm that aproximately locates the mobile on the map.
The following figure shows the process.

A machine connected to the Cellular central downloads the data of cell and channels that the loaded mobiles take. This data is sent through a IP Network to the different visualization interfaces, in which the information is shown in the following way:
Main advantages:
1- Profit of Network installed.
2- Location on line.
3- Intercept in direct or in differed.
4- Open to new implementations of software for automation of processes.
5- Very good approximation in zones of high density of Bases Radio.
6- Historic Registration and statistical capacity of prosecution.
7- Additional Possibility of information as incoming and outgoing calls.
