Carrier Aggregation on Airtel 4G LTE

[Raj]

Just checked today. Airtel started using 20 + 10 Mhz of Band 40(2300 Mhz) CA in Chennai. Speed was a bit low, maybe because of peak time. Can able to hit 25 Mbps.

I was able to get quite good speed on Airtel with carrier aggregation on Band 40(20 Mhz) + 40(10Mhz) as that configuration is the only one which my device supports by default.

Jio started carrier aggregation between Band 3 10 Mhz and Band 40 20 Mhz in MP. Peak speeds were around 120 Mbps

Its lte advance. I think it means two band of 1800used means 5+5mhz.

Airtel is making serious progress in many places I tested in Chennai. I can see speeds consistently 50+ Mbps in workplace where speed was barely 3-4 Mbps few weeks back. Looks like might have implemented Indoor Small Cell with Fiber Backhaul and possibly Massive MIMO. The high speeds are 2 CA (20 + 10 Band 40 CA). Even in my home getting good speeds where it used to be 5-10 Mbps on average. Most of my tests are on OMR. Attaching few Screenshots.

The one with lower speeds are while connected to Band 3 (5 Mhz) and few are deep inside buildings where I didn't even get 4G signal before.

@Raj Wow u are getting very good ping like u get in broadband and for some reason my ping is fluctuating too much like from 70-300 ms from a week but before i used to get around 20-30ms ping

 

[Raj]

Higher ping maybe due to bad routing. I used to face this issue often in Jio. Airtel very rarely.

 

[GR2]

@Raj Or it may be because of upgrading the tower? I am saying this because i am seeing 3+40+40 and 40+40 from few hours which i didn't see before or if that's because of routing how do i complain then? Is there any nunber to call them.

 

[Raj]

Looks like they are upgrading the towers and also seem to have increased Backhaul capacity.

In Samsung devices in you can view these details in Service Mode using the dialer code *#0011#. No root needed.

@invisible007 If u have samsung dial *#0011# and select the stack. If u are using different smartphone download net monster app from play store or if ur phone is rooted download network signal guru
