I. Introduction
This extended abstract describes the outcomes of our senior design project, conducted at Florida International University during Spring and Fall 2014. The goal of the senior design project was to design a flying GSM relay copter, which can help in maintaining connectivity in emergency scenarios in which the communication infrastructure is not operational. This may help in maintaining broadband connectivity between first responders even in the absence of any nearby base station. We implemented the GSM base station using the OpenBTS software and universal software radio peripheral (USRP) software defined radio (SDR) equipment. The prototype was fully developed, and its operation was demonstrated during the senior design day at FIU Electrical and Computer Engineering department.
