Abstract:

Long Term Evolution is the mobile technology that designed for high-speed internet connection. This was due to previous mobile technologies to provide low unsatisfactory data rate expectancy to the mobile operators and mobile users. It designed to operate in a licensed spectrum and not unlicensed. But due to the capacity demand which raised due to increase in iPad, Tablets, Smartphones, and other wireless devices the channel capacity now become a challenge. Therefore to increase channel capacity communication, the Long Term Evolution technology to operate in unlicensed has proposed for use as alternative for this problem. This challenge place Long Term Evolution into consideration to operates in unlicensed spectrum. Unlicensed spectrum is the spectrum that has higher, free and, larger bandwidth on which wireless devices operates in this spectrum. Increasing wireless capacity demand as well as bandwidth from mobile subscribers, the mobile operators now are increasingly concerned to deploying and utilizing unlicensed spectrum for mobile network communication. In this study, the methodologies that have been used to achieve the objectives of this study were systematic literature reviews have been used and, simulation by using Matlab, Atoll and, Mentum Planet were used From simulation, Long Term Evolution (LTE) in unlicensed spectrum the throughputs was 100Mbps and, 98Mbps in licensed spectrum. This improvement is equal to 2%. Therefore there is an improvement of Long Term. Evaluation performance in unlicensed spectrum compared to LTE in licensed spectrum. This is due to availability of larger bandwidth for free, hence increase channel capacity for mobile communication.
