Abstract: 
This work describes the potential gain of spectrum sharing between different mobile technologies. A new bandwidth allocation technique is introduced, allows coexistence and overlap between old and new (relative) mobile generations, operating over the same frequency band. The new proposed technique is tested over UMTS and LTE systems to enhance the overall spectral efficiency. LTE bandwidth is maximized allowing carrier overlap with UMTS. Spectrum sharing feasibility is being assessed in 2100MHz band. The proposed UMTS and LTE coexisting setup allows carrier overlapping in both uplink and downlink channels. Performance is evaluated in terms of statistical analysis and field measurements. The proposed test case evaluate the system's performance and measure the induced interference from each system on the other. Results have shown the do-ability of overlapped spectrum sharing between different mobile generations, in order to enhance the system performance.
