Effect of Operating Frequency on Performance of LTE and LTE-Advanced Systems

Jolly Parikh, Anuradha Basu

A vast pool of frequency bands from 450 MHz to 3.6 GHz is available for deployment of LTE and LTEAdvanced networks. But with increase in the operating frequency path loss increases which in turn impacts the coverage area of a base station. Accordingly the number of base stations increases which leads to increase in the cost of deployment. Availability of spectrum in high frequency range is not an issue but it has its own pros and cons. This paper discusses the effects of deploying networks at high frequency versus deployment at low frequencies. The LTE system level simulator by Vienna has been used to study the changes in path loss with changes in operating frequencies of 0.8 GHz to 2 GHz.
