Interference between two RAT (Radio Access Technology) wireless networks will lead to the system capacity deduction. In this paper, system capacity loss was analyzed by using snapshot method and the simulation results show that system capacity loss is closely related to the relative offset and antenna direction between two RAT wireless networks. Based on the interference analysis above, a novel wireless architecture was proposed by rotating antenna direction and adjusting offset between two RAT wireless networks. Simulation results verified that it can effectively avoid system interference.
