Abstract:

In this paper, we evaluate the performance of UMTS (Universal Mobile Telecommunication System) downlink system in vicinity of UWB system. The study is achieved via simulating a scenario of a building which is located within UMTS cell borders and utilizes from both UMTS and UWB appliances. The simulation results show that the UMTS system is considerably affected by the UWB interference. However, in order to battle this interference and achieve reasonable BER (Bit Error Rate) of 10-4, we found that it is very necessary to carefully raise the UMTS base station transmitted power against that of UW

Abstract:

<span>Sistem celuler GSM memiliki beberapa kekurangan, yaitu tidak mampu untuk mengintegrasikan layanan video call dan video streaming karena kecepatan data masih rendah. Dengan alasan itu, maka ETSI menentukan migrasi dari GSM ke sistem generasi seluler ketiga yang disebut dengan UMTS (Universal Mobile Telephone System). Adapun spektrum frekuensi UMTS terestrial bekerja pada 1920-1980 MHz, 2110-2170 MHz untuk dipasangkan dari band dan 1900-1920 MHz, 2010-2025 MHz untuk tidak berpasangan dari band Seiring dengan perkembangan teknologi, teknologi telekomunikasi sistem seluler terus berkem
