THEORY OF OPERATION Dual Band 880/890 (DCS/GSM) Cellular Subscriber Sector Theory of Operation GSM System Overview Using this technique, radiation on a given channel is virtually contained in the cell operating on that channel and, to some extent, those cells directly adjacent to that cell.
Page 16
Dual Band 880/890 (DCS/GSM) It is designed to carry digital voice and The radiotelephones themselves are capable data over existing copper telephone of operation on any channel in the system, cables. The GSM phone will be able to allowing them to operate in any cell. Due to...
Page 17
Theory of Operation The data blocks are modulated onto the Signal information provides an indication of carrier using Gaussian Minimum Shift the subscriber’s distance from the base Keying (GMSK), a very efficient method of station. As the radiotelephone moves from phase modulation.
