Abstract4G Long Term Evolution (LTE) has a standard for wireless communication with high-speed data access on cellular phones which have standard parameter i.e. power control. Power control is a method to avoid interference inter-users, as a result of power variations. Interference inter-users will cause performance limitations of the quality of service telecommunications operator. In this paper, we will design power control on the uplink channel based on the Signal to Interference Ratio (SIR) so that power level of mobile station (MS) are approximately equal. Simulation results show that power of MS can reach -7 dB, average time above 17 ms. The results of the SIR can order MS to equalize the SIR power levels transmitted by some MS with SIR reference value. Keywords: power control, uplink channel, SIR, mobile station Abstrak4G Long Term Evolution (LTE) memiliki standar komunikasi nirkabel akses data berkecepatan tinggi pada telepon seluler yang memiliki parameter standar yaitu kendali daya. Kendali daya merupakan metode untuk menghindari interferensi antar pengguna akibat variasi daya. Interferensi antar pengguna menyebabkan keterbatasan kinerja kualitas layanan operator telekomunikasi. Pada penelitian ini, akan dirancang kendali daya kanal uplink berdasarkan SIR agar daya mobile station (MS) mendekati sama. Hasil simulasi menunjukkan bahwa daya MS dapat mencapai -7 dB, rerata waktu di atas 17 ms. Hasil menunjukkan SIR dapat memerintahkan MS menyamakan daya yang ditransmisikan beberapa MS dengan nilai SIR referensi. Kata Kunci: kendali daya, kanal uplink, SIR, mobile station

Now a days in Wireless Local Area Networks (WLANs) used in different fields because its well-suited simulator and higher flexibility. The concept of WLAN  with  advanced 5th Generation technologies, related to a Internet-of-Thing (IOT). In this project, representing the Network Simulator (NS-2) used linked-level simulators for Wireless Local Area Networks and still utilized IEEE 802.11g/n/ac with advanced IEEE 802.11ah/af technology. Realization of the whole Wireless Local Area Networking linked-level simulators inspired by the recognized Vienna Long Term Evolution- simulators. As a outcome, this is achieved to link together that simulator to detailed performances of Wireless Local Area Networking with Long Term Evolution, operated in the similar RF bands. From the advanced 5th Generation support cellular networking, such explore is main because different coexistences scenario can arise linking wireless communicating system to the ISM and UHF bands.
