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

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.
