    Default LTE 20M vs LTE CA 10M ?

    Dear LTE experts,

    What do you think the best strategy to deploy one 20M LTE carrier or two 10M LTE carrier and benefit from CA ?

    In which case I got higher real throughput ?

    Thanks

    Obviously, it will be the 20 MHz LTE carrier. Saves you on the overheads and you get better utilization, UE and cell throughput. But, it is not easy to find contiguous 20 MHz spectrum. So, operators explore intra-band and inter-band CA to muster an aggregate bandwidth of 20 MHz.

    Go for 20MHz, not all UE's allow CA. Evenfought that I do not know a case were Intra-band CA would not be allowed.But I know cases like Xiaomi UE's that support some bands (e.g. B1, B3, B7, B20) but don't allow CA between them.. Best performance with less wasted resources is with one block.
