    Mates, Could any one post some latest materials on VSAT systems. Thanks.
  3. Re: Calculating Signal strenghts in different frequency bands

    Eric, the SS will depend on the frequency, clutter (terrain + morphology), the placement of antenna(antenna height of BS and UE). If the antenna height is above the average roof top level, then it is...

    Re: MIMO 2x2 to 4x4 Change

    Less than 1percent of UEs in a cell would actually use MIMO 4x4. 50 percent of UEs. Only the UEs very close to the base station can be served with 4x4 MIMO because of the high S/N requirements.

  7. Re: Coverage by Signal Level vs Coverage by RSRP Level

    RSRP level is based on signal level, but the catch here is that it represents the signal level of camped cell and the neigboring cells. So, it contains interference from other cells. We need another...

  23. Question Re: Why SS-RSRP is measured in 5G NR instead of PS-RSRP?

    The center 20 RB carry the SSS. It also carries the reference signals. So, the UE does not have to scan the entire NR bandwidths. Remember, NR supports bandwidths of upto 400MHz, and scanning this...

    Question Re: LTE 20M vs LTE CA 10M ?

    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...

    Re: LTE MIMO : RANK, LAYERS and Antenna ports

    3GPP specs are not mandatory for the operator. It is left to the operator's volition. It can be said that only regulations are mandatory.
