Savita Tauro 1. 4.3 Understand the concepts of cellular communication system. Cellular networks will be emphasized in this chapter, both because they are of great current interest and also because they involve a relatively simple architecture within which most of the physical layer communication aspects of wireless systems can be studied. Hence it results to give the first insight of cancer on molecular basis. Cell signaling is a method of communication of one cell with other cells. This is done by following methods like Synaptic signaling. Cells need to communicate with other cells for the normal physiology of the body. Sometimes they signal the nearby cells, and other times they signal to distant cells. Lipids are not just used as a passive component of membranes, or as a source of stored energy. Available For. G Protein Coupled Receptors. The coverage area of cellular networks are divided into cells, each cell having its own antenna for transmitting the signals. Each cell has its own frequencies. Data communication in cellular networks is served by its base station transmitter, receiver and its control unit. If a cell type is either scarce or overabundant in the bloodstream, this may reflect a problem.
