Analisis Koeksistensi Jaringan LTE Non Lisensi dan Wi-Fi Pada Frekuensi 5GHz

Abstrak

By the 2020 the traffic internet demand will be increasing, so that the utilization of spectrum frequency should be maximize and use wisely. LTE-U which is using unlicensed spectrum frequency may be option to fulfil the demand of the internet traffic. Unfortunately it has to adapt and coexistence with Wi-Fi which already exist in unlicensed spectrum frequency. In this research, will talk about the minimum distance needed so that LTE-U eNodeB and Wi-Fi can be coexistence in indoor and outdoor deployment LOS and NLOS condition. The coexistence analyze in ACIR value. The result, minimum distance needed is in range 16 m-35 m for indoor deployment. In the other hand 51 m-199 m for outdoor deployment. With software simulation in 51 m distance the mean CINR value is 15 dB, and for 16 m distance the mean SIR value is 0.62 dB.
