Performance analysis of LTE networks in varying spectral bands

The ever increasing number of mobile broadband users requires the availability of enhanced data services. Long Term Evolution or LTE is the evolution of High Speed Packet Access (HSPA), which was standardized by third generation partnership project (3GPP) Release 8 in order to meet the increasing demand of faster and more efficient mobile internet access today by supporting the larger bandwidth. This paper analyses the performance of LTE network in varying spectral frequency bands. Using network simulator-2, ns-2, the parameters that had greater impact on the performance were studied. The main key parameters which were used to evaluate the key performance analysis are throughput, average throughput and jitter. Based on the simulation results, we have concluded that throughput remains same at different frequency bands if bandwidth and modulation type is same. Average throughput also does not change with the change in frequency band, but average throughput is lower in comparison to throughput because same bandwidth is shared by all the nodes. Thus, we can say average throughput decreases with increase in number of nodes. Jitter does not have any specific trend normally it increases with the increase in frequency band, sometimes it is same as frequency band increases and it also decreases when frequency band increases.
