On the WiMAX System Co-ezistence with WCDMA and cdma2000 1z System
Mobile WiMAX based on IEEE 802.16e standard can realize enhanced network capacity requirements and various services as well as provide more novel experiences for users. Since WiMAX joining in 3G camp as the new member, the coexisting research of WiMAX and other 3G system (WCDMA, cdma2000 1x and TD-SCDMA) deployed in the same service area has gained increasing importance. In this paper, the detailed coexistence issue analysis, including several interference scenarios, network deployment, propagation models and interference models, is described. After some necessary assumption and simulation parameters, system capacity loss due to co-existence of WiMAX and other 3G network on close frequency bands is investigated. The interference cases of BS-to-BS and MS-to-BS with WiMAX deployed respectively with cdma2000 1x and WCDMA in neighbor bands will be discussed and analyzed. At last, some suggestions are to be proposed to better realize the coexisting of WiMAX and other 3G systems.
