Because Qualcomm is the initiator, developer and promoter of cdma system, he has more than 3,900 patents and patent applications for CDMA and related technologies. More than 65,438+038 telecom equipment manufacturers in the world can only operate cdma business after obtaining the cdma patent license from Qualcomm. China Telecom gives 4% of cdma revenue to Qualcomm every year, and Qualcomm is the king of CDMA. 95% of cdma is monopolized by Qualcomm. If you don't buy the baseband from Qualcomm, you must pay the patent fee to Qualcomm.
To put it simply, Qualcomm is a cdma roadblock. Even if you don't buy his things, you have to pay for them.
