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.
