Open BTS Implementation With Universal Software Radio Peripheral
نویسنده
چکیده
Open base transceiver station (BTS) project was originally developed using open-source Unix/Linux applications in conjunction with Universal Software Radio Peripheral (USRP) to implement GSM (Global System for Mobile Communications) air interface supporting GSM handsets at much lower cost than commercial carrier BTS systems. This paper emphasizes concepts and methodology of low cost Open BTS implementation using USRP-N210, made by Ettus Corporation. A complete GSM BTS system utilizing Asteirsk, a VoIP (voice over IP) PBX (private branch exchange) software application, is implemented to simulate incoming and outgoing voice calls between soft-phone and open GSM handsets. Furthermore, a complete GSM network system will be designed using OpenBTS components for a small island nation and design feasibility from cost prospective will also be analyzed.
