Recently, Long-Term Evolution (LTE) is the result of ongoing work by the Third Generation Partnership Project (3GPP) toward Fourth Generation (4G) systems. LTE will be used for mobile, fixed and portable wireless broadband access, and will offer several benefits to operators, aimed at increasing capacity, reducing network complexity and thus lowering deployment and operational costs. It will enable operators to meet the growing demand for mobile data solutions, making it possible for richer services to be delivered to consumers more cost effectively. The targets for LTE indicate bandwidth increases as high as 100 Mbps on the downlink, and up to 50 Mbps on the uplink. However, this potential increase in bandwidth is just a small part of the overall improvement LTE aims to provide. This study illustrates the model and representation of LTE links and traffics using NS-2 network simulator and observation of TCP Reno performance investigated. The Evaluation of the network performance with TCP Reno is mainly based on congestion window behavior, throughput, average delay and lost packet.
