Airtel signal weak inside home but ok outside home

Hi i have airtel 4g but the signal is very weak inside my home here in Delhi.

However when i step outside my house the signal is ok.

Is there any way my signal at home can be amplified via some device sold by Airtel itself or 3 rd party? Thanks!

How weak is the signal ?

Note that it's normal for the Airtel 4g signals to get really weak when inside the house. They use Band 40, 2300 MHz frequency which is known to have indoor coverage issues.

You can call Airtel and keep complaining, they don't sell any equipment to boost signals but are known to install amplifiers for coverage issues that are reported by end users who are much affected by indoor coverage only. That's your only hope.

2300 MHz, Band 40 amplifier kits are commercially available for over 10k in open market. Buying the genuine product that actually works and getting it installed can be quiet tricky as well

Airtel got 1800mhz lte also active in delhi. At my home 4g signal improved a lot, noticed on samsung mobile it is 1800band indeed. so they're improving it gradually.

In Bangalore they only operate on 2300 MHz and hence the indoor coverage issues
