Wireless communication is playing an important role in our daily life since it offers flexibility and mobility.
New multimedia services demand data-rates of up to hundreds of Mbps and thus higher frequency bands are being
explored to support these new high data rate services. LTE (Long Term Evolution) has been standardized in 3GPP (3rd
Generation Partnership Project) to provide higher data throughput as well as lower latency for various IP based
services including web browsing, VoIP (Voice over IP), video streaming and so on. However, to support mobility,
handoff is a must in many of these networks and systems. The high reduction in signal strength as a function of distance
results in a small coverage area, thereby causing frequent handoffs for mobile terminals. In this paper we give an
overview of the LTE intra-access handover procedure. We investigate the effect of handover on TCP and UDP
throughput and delay.
