In mid-1985, Qualcomm was hired by to provide research and testing for a satellite network proposal to the (FCC). The following year, Qualcomm filed its first CDMA patent (No. 4,901,307). This patent established Qualcomm's overall approach to CDMA and later became one of the most frequently cited technical documents in history. The project with the FCC was scrapped in 1988, when the FCC told all twelve vendors that submitted proposals to form a j.
