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