    well anni,

    Ec/Io is the total Energy per chip divided by the total inference in the 1.25 Mhz spectrum(whole CDMA spectrum).It should be above a certain value so that the mobile can be distinguished by the BTS.

    In CDMA Tech.

    Forward Channels-

    -Pilot Channel
    -Paging Channel
    -Sync Channel
    -Traffic Channel

    Reverse Channels-

    -Access Channel
    -Reverse Traffic Channel

    Pilot Ch.- The pilot channel is used by the mobile unit to obtain initial system synchronization and to provide time, frequency, and phase tracking of signals from the cell site.
