Abstract：Wireless data access services mainly happen on indoor．For the complementary and heterogeneous integration of 3G mobile access and WIFI fixed access，3G+WIFI becomes the major deployment model among the major telecom operators．However，multi-system coexistence，especially with the same station address in the same intelligent building，makes the interference problem more complex．This paper analyzes the multi-system coexistence interference based on categories and mechanism，gets the corresponding analytical relations of common indicators，which can deduce the quantificational conclusion of multi-system interference combination．
