COEXISTENCE AND SHARING STUDIES OF COLLOCATED AND NON- COLLOCATED FOURTH GENERATION NETWORKS IN THE 2.6 GHZ BAND

Lots of fourth generation (4G) wireless networks are currently being deployed globally with similar or with dissimilar technologies in various operating bands. In this paper, spectrum sharing and coexistence scenarios of the 4th generation networks in the band (2500-2690) MHz are addressed. Interferences from Long Term Evolution (LTE) to Worldwide Interoperability for Microwave Access (WiMAX) systems and vice versa are carefully investigated. The collocation and coexistence requirements in terms of separation requirements as well as additional isolations are fully addressed. Interference measures of the two systems as functions of adjacent channel interference power ratios are also considered. Finally, the impact of deployment morphologies of the two systems is accounted for by catering for losses due to surrounding clutter.
