    CE Calculation.

    Hi Experts,

    Could You pls explain why we need more CE's in the Uplink than in the Downlink.



    Pls share any CE planning Document.

    Thanks

    CE's in the Uplink and Downlink capacity depends on vendor you use in your network

    Caused the demodulation process... related to UE requesting the access. Coverage BTS also involved in the user identity

    CE is the demodulation capacity, and is activated by licenses; but there are limits; I mean is not enough to buy more licences to increase capacity, you must consider that sistema capacity is limited by interference,downlink power, etc. Also capacityis shared between voice and data.
