LTE Network: Performance Analysis Based on Operating Frequency
LTE is a widespread technology for high-speed wireless communication that is used in our mobile networks and various data terminals. With the increase in number of users for broadband communication, the requirement for data rate has increased significantly due to the evolution of LTE took place. LTE is the evolvement of high-speed packet access (HSPA) that was assimilated by third-generation partnership project (3GPP) release 8, in order to accomplish widening demand for a very high-speed and proficient access of data. LTE promoted such a high-speed data by enabling larger bandwidth. This paper focuses on the performance of LTE networks at changing spectral frequency bands. In our work, we have tried to simulate LTE networks using NS-2 simulator. Our primary focus is on specifications that greatly affect the behavior of LTE networks. The key specifications that we have used in our work are throughput, average throughput, and jitter. After simulation of our LTE networks, we have concluded that with changing frequency bands, throughput is not affected until and unless bandwidth and modulation type are not varied. We have observed same behavior in case of average throughput but it is smaller in comparison to throughput as bandwidth is shared among multiple broadband users; hence, it can be noted that average throughput falls off with the rise in number of nodes. Jitter does not show any distinct behavior with changing spectral frequency band. It may rise for some instance of time and diminish for other instants.
