Implementing an Enhanced base station using the software defined radio (CUOPENBTS)

Abstract

An enhanced OpenBTS is implemented. OpenBTS is a software-based GSM access point, allowing standard GSM-compatible mobile phones to make phone calls without depending on existing telecommunication providers' networks. In this paper, the goal was to improve the design of the OpenBTS system by improving the sensitivity and also minimizing the cost of the whole system. So far, we implemented a base station using state-of-the-art software and hardware components, namely GNU Radio and, OpenBTS software with USRP and a single WBX daughterboard hardware (CUOpenBTS), and made a phone call using regular GSM cell phones.
