Carrier Aggregation on Airtel 4G LTE

[RummaanKhan]

Jio Uploads speeds are better in Galaxy A70 than Nokia 7 Plus in the same location. Both Band 40 and Band 3 gives 12Mbps upload on A70 and 9Mbps Uploads on Nokia 7 Plus.

@RummaanKhan thats because a70 supports 64Qam in uplink.

 

[RummaanKhan]

@Ak5877 Does it supports 256 Qam?

 

[Deleted member 75747]

@RummaanKhan Yes it supports 256Qam in downlink.

@RummaanKhan thats because a70 supports 64Qam in uplink.

On Airtel network on A70 i get only 9 Mbps Uploads speeds so it means network doesn't support 64 qam

@RummaanKhan on Airtel network 64Qam hardly activates on b40.Mosty its 16Qam or even sometimes QPSK

@Ak5877 even on Band 3 and Band 1 max upload speed I get is 9.8 Mbps.

@Rudecat in chennai both b3 and b1 has 5mhz thats the reason.in my location i have got 20mbps on b3 and b1 on 10mhz bw.

@philip How 3G can run on B3?AFAIK 1800mhz DCS can be used for 2G and 4G services only

Sorry i meant Band 1 2100 mhz.

You can root it and lock bands with NSG.But once you root it you loose many things.Even after unroot knox will remain tripped.And you will loose warranty.

So i thinking porting to jio is the only option now . Since i dont feeling like rooting my phone since it is only 1 week old.
