Abstract LTE Release 13 allow the use of unlicensed frequency variations called Licensed Assisted Access (LAA). Combination of licensed LTE is used as primary cells to carry information and transport traffic data. Whereas the unlicensed spectrum is used as secondary cells that are proposed to increase capacity and distribute the spectrum fairly. The simulation results of scenario 1 produce a fairness index of 64 users for FTP over UDP in scenario 1 of 0.998, scenario 2 is 0.857 and scenario 3 is 0.997. Whereas for FTP over TCP in scenario 1 is 0.779, scenario 2 is 0.639 and scenario 3 is 0.74.
