Introduction Analysis of technical devices that are aimed at tracking criminals may be performed from several perspectives. These are the effectiveness of tracking, the adequacy and reason of using any particular technology, wideness of using these devices by safety structures and state bodies. The analyzed article is touching upon the technical aspects of implementing the cognitive radio mobile systems for tracking criminals and creating the database of criminal movements and visits. Hence, it is stated that the system may be used for locating the possible locations of storehouses, secret addresses, etc. Article Analysis The importance of the selected topic is generally defined by the statement that tracking and wireless technologies are at the dead-end of their development. Cognitive radios are aimed at overcoming this dead end, by widening the horizons of wireless tracking. As for the realities of contemporary technological development, the article is aimed at emphasizing that the demand in using wireless technologies is increasing intensively, however, the opportunities of the IT sphere are not sufficient for creating the proper and reliable tracking system. Hence, Arslan and Yarkand emphasize that the reliable tracking system requires the development of software-designed radio, as the IT base will be able to provide the necessary opportunities for developing the Cognitive Radio systems. The key advantage of this system is explained by the multi-dimensional approach towards tracking and cognition of the surrounding atmosphere. The dimensions and parameters may be adjusted by the necessities of the organization that performs tracking, and the aims of the tracking in general. Dimensions of Cognitive Radio tracking depend on the prioritized directions of cognition development, as while the system may be perfect for tracking the location, there may be numerous drawbacks in tracking the noise and sound surrounding. Additional options will require additional devices or analysis components, which excludes the opportunity of creating cheap, effective, and universal devices. Moreover, various analysis components of the device will inevitably interfere with the work of each other. Technical Aspect of Tracking It is emphasized that wireless technologies are comfortable, universal, require minimal resources, nevertheless, they have essential drawbacks. The Cognition Radio tracking system will inevitably suffer radio noises and reflections which lower the effectiveness of the system in general. Considering the fact that these reflection and noises may create essential interference into the work of similar systems, there is a necessity to implement additional noise protection systems that will require additional modulation – demodulation systems. In accordance with Asrslan and Yarkan, another weak point of wireless systems is the time and frequency selectivity parameters. Considering these aspects, it should be stated that the necessity of further wireless technology development is obvious, as an effective tracking system should be perfectly selective and do not interfere with the work of other elements of the entire system. The importance of such technology may be explained by the growth of crime rates in some corners of the world. However, if the importance is not doubted, the development of the system should be performed with the increased rates, while the current phase of the technol
