Study of Spectral Efficiency for LTE Network

Grigol Basilashvili


The efficiency with which spectrum is used in wireless communication systems is becoming increasingly important as a result of rapidly growing demands for bandwidth-intensive mobile broadband services and the finite nature of usable spectrum. Faced with ever-increasing cost pressures, it is significant for mobile network operator to make the most of spectrum investments. Therefore, this paper serves audience to better understand spectral efficiency, the factors that influence the efficient use of spectrum, the ways of measuring it and finally, what can be done to improve this wireless network performance metric.
