Carrier Aggregation on Airtel 4G LTE

[Deleted member 75747]

4X4 mimo also does not work properly on all sites.In many sites when 4x4 mimo is active transmission mode changes to TM2 from TM4 and as a result speed does not increase that much.Out of 10 only 3 sites properly support 4x4 mimo on b40 on airtel and on those only speed almost doubles.

There is one advantage of having single vendor partnership like Jio with samsung is uniform network performance all over India. Their pan India CA and 4x4 MIMO is an example of it. But if samsung closes networking business means it will be tough for Jio.

Yes Jio 4x4 mimo is very stable.Out of 10 i guess 9 sites properly work with 4x4 mimo and speed almost doubles.

Yes Airtel and Vodafone is using mixture of old and new hardwares resulting in poor implementation. Core network one vendor and BTS one vendor,volte another vendor resulting in technical difficulties.

Yeah i wish Airtel upgrades their network properly its total shit here in Kerala in most of the sites after 7PM u cant even text someone upload speeds are literally 0.00

Then I guess in kerala they hadn't enabled 3ca.The speeds are pathetic with band 40 and band 40 carrier Aggregation

3CA is enabled in Kerala all combinations work here 3+5+40 , 3+40+40, 40+40 5+3+40
Even 4x4 Mimo works in Band 3,40

@amalrakoff But 4x4 Mimo is of no use in Jio as it's Capped to 100Mbps only which Single Band 40 with 4x2 Mimo is able to provide.

@amalrakoff i only get TBD 4 in excellent signal in S8 and S9+.I also don,t get 4X4 mimo in b3 neither in samsung nor in OnePlus 7 though network signal guru shows 4x2 in b3.I only get 4x4 on b40.I don,t know what is the problem?
