Abstract
This paper describes the design and implementation process of a 2.5G GSM network. The GSM network supports messaging, voice calls and data through GPRS. We have also explored the spectrum analyzer, FM radio receiver and transmitter using USRP B200 software-defined radio (SDR). OpenBTS, GNU radio, with USRP hardware driver (UHD), Asterisk and Fosphor are used to control and configure the USRP B200 SDR on the software side. A GPU accelerated spectrum analyzer that works from 70 MHz up to 6 GHz is also included. There is also an FM radio transmitter that can transmit on any selected frequency and an FM receiver that can receive and play all the stations available in the area through the computer’s speakers. We also observe the effect of distance on signal strength and delay.
