2.9 – CARRIER AGGREGATION TECHNIQUE (CA) -CAPACITY & COVERAGE ENHANCEMENT IN 4G LTE



CARRIER AGGREGATION TECHNIQUE (CA) -CAPACITY & COVERAGE ENHANCEMENT IN 4G LTE

Imagine a road is connecting two places. Now, As the number of people travelling increases, what do we do to serve the increased traffic? We add more lanes or construct flyovers.
Similarly in LTE, Carrier aggregation is used to serve increasing bit rate demand. Here bandwidth is increased by aggregating separate spectrum, thus increasing the bit rate and network performance.

We have shown the different technique can be use to deploy CA, such as
Intra-band Contagious – easiest to deploy
Intra-band Non Contagious – used in fragmented network
Inter-band – Complex

also we have shown the LTE CA Classes to differentiate from others.

It also includes gradual work done at different country to deploy CA and plan for the future release.

This is the ninth Video of the LTE- Fundamental series

    Good video, is there any video on Dual Connectivity ? Why we need dual connectivity , what is the difference between DC & Inter ENB CA. Thanks

    I used to hear a nice voice on this channel videos, but unfortunately, this video uses an awkward accent and I can hardly understand

    I am sorry , you are doing a great job. I really understand a lot of concepts easily. However, the accent in this video makes it tedious and so difficult to absorb the information presented here. you are explaining to the whole researchers who they are from various countries not only from India. So I recommend strongly to help all people to get benefits from your amazing explanation, you should use a clear accent not the Indian one .
    All my respect for you amazing channel.

    why did you change the lecturer , the language in this video is not clear at all as it's an indian accent.
    his English is not clear as well as previous videos.
    dislike for the ambiguity and inability of understanding what's mentioned in this video.

    Two questions dumb perhaps:
    1) Isn't SCC eNB too distant for UE to well receive the signal? Thought the UE Rx would be designed to receive the signal within main cell rather than neighboring cell?
    2) Can the Antenna operate at two or more carriers simultaneously when running CA?

    If a operator having 3 freq band 2300 1800 and 850 having 20 10 5 mhz freq. What will be the scenario in term of CA in this case. Pls explain.

    Great video! I love your series. I must note that I prefer the synthesized voice as it was easier for me to understand. Keep up the awesome videos.
