For a Mobile Network Operator (MNO), the most precious yet scarce resource is the harvested spectrum. With the rise of global mobile data usage and increasing signaling traffic enabled by the emerging IoT (Internet of Things) applications, the need for more spectrum for LTE and beyond resulted in ultra-expensive spectrum auctions all around the globe. Even with more spectrum allocation in the sub 3 GHz bands, the demand for more bandwidth can only be partially satisfied. Therefore, it is inevitable to re-use the existing spectrum to increase capacity utilization and reap the benefits of much higher spectrum efficiency in new Radio Access Technologies. The objective is to allocate some part of the underutilized frequency bands to more advanced mobile technologies, which is LTE in this case. In addition, as GSM networks are about to complete their life cycle, frequency bands allocated to this technology should be refarmed and used for providing more advanced mobile services to customers.
