Abstract :
In this demo, we demonstrate integration of cognitive radio capabilities, on the fly, with GSM base station (BTS) using OpenBTS architecture. The demonstration has following novel features: :Cognitive sensing of the channel, in use by secondary user, while transmitting, :On the fly shifting to free GSM subchannel without call drop, :Works with existing GSM phones without any modification in hardware and software. Trials at IIT Hyderabad over the last one year has validated the viability of the system.
