Abstract
GSM technology is one of the wireless communication networks which is the easiest and most viable solution for robust voice communication. No wonder it is the most successful communication standard in the world covering over 90% of globe population. In spite of this, it has been repeatedly observed that utilization of GSM spectrum is poor. The resources available to support the users in
wireless communication networks are very limited. In particular spectrum that are used as a pathbetween users are scarce and underutilized. For example in New York and Chicago, GSM cell phone frequencies are occupied 45% and 55% of the time.
