Implementation of GSM and LTE Re-Configurable Cellular System Using USRP B200

In this paper, we implement GSM and LTE re-configurable cellular systems for disaster affected regions using Software Defined Radio (SDR). SDR is a key concept in wireless communication. Wireless communication is widely used in all over the world for various types of audio, video and data transmission. It is experienced that during disaster, commercially available cellular networks fail and small scale private cellular network can be utilized to restore the emergency communication for disaster management. Traditional private cellular networks are not only costly but also difficult to acquire and hence demands a cost effective and affordable solution. In this research, SDR based cellular network is established in two phases. In the first phase, we implement a GSM network using USRP B200 and OpenBTS, enabling voice call, messaging and gprs facility. Whereas, in the second phase, we implement an LTE network using srsLTE and USRP B200, where for authentication we have performed USIM programming. Our LTE network provides audio-video calling, messaging, browsing and the data transmission facility. Overall performance of the SDR implemented cellular network is satisfactory for emergency communication. The implementation codes have been uploaded in the link below: https://shorturl.at/eluS8.
