Communication has always been a main component of education, an indispensable support for the education system. Receptive to the human communication development, the timeless school practice has never stopped to wisely integrate and absorb the various verbal and non verbal forms and means in its procedural structures. This is today more obvious than ever, in a society of knowledge and globalised communication, when the act of communication is applied effectively in all domains of inter- personal activities and human social life. A major role is played today in this context by the powerful technological communication tools, with major implications in the development of the educational system.

In recent years, cellular communications technologies have made quite significant advances in the civil field with the establishment of the GSM standard for global mobile communications. GSM-based Public Land-Mobile Networks (PLMNs) are currently operational in more than 56 countries. This leads to the question as to whether or not GSM-PLMNs systems could be used for military applications as well. (Mil Technol/SWP)

Florida Technological University College of Engineering Thesis; This is a study of the methods of control of an advanced military communication system. The Tactical Communication Control System has been conceived t o meet the demands of military users which are currently both analog and digital but steadily evolving to all - digital . It is a study of the design and application of multiplexers, modems, processors, switches, and other nodal equipment to accommodate communications among telephone and data users in a tactical environment. The main points of interest are the communication node and the control techniques used to carry out system objectives. ; 1975-01-01 ; M.S. ; Engineering ; Masters ; This record was generated from author submitted information. ; Electronically reproduced by the University of Central Florida from a book held in the John C.
