Abstract
One of the outcomes in the last world radio communication conference 2007 (WRC-07) is assigning the 790-862 MHz band to the digital broadcasting (DB), and the new mobile system called International Mobile Telecommunication - Advanced (IMT-A) in co-primary basis in 2015. Until that year, the primary service (i.e., DB) should be protected from the new system (i.e., IMT-A). This paper investigates the spectrum sharing requirements such as separation distance and the frequency separation between DB and IMT-A in the 790-862 MHz band. Our study utilizes the Interfere Spectrum Emission Mask (ISEM) and the victim receiver blocking (VRB) as spectrum sharing models based on the Interference-to-Noise ratio (INR) if -6dB as a spectrum sharing criterion. The results show that high interference impact occurs in rural area deployments, whereas, the coexistence could be achieved in urban areas, requiring less separation distance. (4 pages)
