Social networks like Facebook, Twitter or LinkedIn offer the opportunity to communicate and collaborate with friends and family in our personal life through the social technology without seeing each other on daily bases. This different approach is already common to be used for the majority of people and brings new benefits to now-a-day global environment. The same users of these external social networks are working in companies with various internal collaboration and communication tools. This fact has become stimulus for the theory of using social network technologies inside of the organization called Social Business. Social Business brings multiple new benefits for the organization, which were not possible to be gain through the previous approaches of communication and collaboration. In the present work we study the process of transforming organization into Social Business.

The diploma thesis describes mobile communication systems GSM and UMTS including the operating principle of these systems. It also deals with the GPS issues and the determination of the location by this system. The signal path losses issues between the transmitter and receiver are also described. The focus is also put on Telit UC864-G model and the measurement system, operated by the created programme with the graphic user interface, which measures parameters of the cellular network according to entered input parameters and saves the measured values into the file. The part of the diploma thesis describes another created programme with the graphic user interface displaying the measured network parameters in map data with the possibility to compare the distribution of the measured signal value in both outdoor and indoor environment and the theoretical value set by the propagation models.
