  • Operation of a CDMA net
    Patent number: 5509002
    Abstract: A code-division multiple-access (CDMA) net can be used for efficiently carrying various types of traffic having different requirements, such as voice traffic and ISDN traffic. When a station requests a channel, the controller determines the quality level required by that station and calculates the appropriate power level for that station on the basis of the required quality level. At the same time it recalculates the power levels for the stations already having operative channels.
