The Analysis and Solutions about PHS and WCDMA Co-exist Interference

This paper analyzed the wireless environment interference between PHS and WCDMA based on the protocol of 3GPP and STD-28 while the field test also verified the co-exist interference.To calculate the MCL,the author measured the spurious of PHS cell-station and cell-phone.The way to judge the interference source and the rule of installing filter to solve the co-exist interference were also introduced.
