The spectrum of the telecommunications industry spans through a range of electromagnetic radiation frequencies. This then is used in wireless communications systems. Conflict now is how do we upgrade or improve the system that is already established? How do we make this present system more efficient to the ordinary user? As a result, this is because of large mobile communications using far less powerful transmitters when compared to broadcasters on the radio. Wireless communications used to be the mainline of telecommunications networking, which carried an excess amount of calls amongst cities as oppose to individual to individual. When the developments of microwave towers were first introduced, this then allowed thousands and thousands of calls to go on at once. A downside to this was that they were using directional antennas which restricted their networking to extend to certain spans. What then happened was that it leads to the introductions of fiber optic integrated systems, and then satellite technology and then cell phones. With all these technological advancements along with the evolution of time, they all faced similar restrictions with their channel space. In present day, technicians are still trying to figure out and develop a new innovation that can handle these limited channel spaces.
