Has slow 4G broadband speeds (especially during this WFH time) made you want to call customer support and cry uncontrollably? If yes, keep reading, this is for you.
Before I start enabling you to watch 4K TikTok compilations with no buffering time, there are a few things to know when it’s come to 4G internet.
Improving your 4G internet speed mainly depends on 3 factors:
1. How close you are to a 4G compatible tower (RSRP)
2. How much interference there is between you and the tower (SINR & RSRQ)
3. What kind of WiFi router you are using
In this post, we’ll be talking mainly about the first 2 points – as those will make the most significant difference in your internet speed.
If you’re interested in understanding more technical details,
First things first: get an app that showcases the stats you need, so you can take a decision.
2. Once installed, make sure you’re connected to your 4G WiFi and open the app up
3. You’ll now see a screen such as below, where information from what band you are currently connected to; to your data usage will be displayed.
The numbers we will be mostly looking at are the dB values next to the RSRP, RSRQ and SINR fields.
The next steps are simple – spend the next 30 minutes (or 2 hours, if you’re like me) testing out multiple new locations, antenna angles and orientations for your router.
Remember, there are probably multiple different cell towers around your house that you could potentially connect to, so don’t limit yourself to just moving your router a couple of feet around on your bedroom window. My advice is to test every location where you have a plug point.
Your starting goal will be to find the best spot for your device where the RSRP, RSRQ and SINR all will have excellent values – as detailed by this chart:
HOWEVER – your no. 1 priority will be to find the location where you can get the highest SINR value possible.
The higher this value, the less interference you will have between your device and the cell tower. This will result in the best possible throughput for your down/upload bandwidth.
Again, it doesn’t matter if you don’t see excellent numbers under RSRP (distance from cell tower), as you can technically achieve maximum speeds even with a value as low as -90dBm.
Here’s the difference changing locations from low SINR to high SINR made for me:
As you can see, I technically had ‘full signal bars’ in both screenshots, however, the improvement to my SINR (higher value means less interference) more than tripled my download speed.
And that’s it! Drop a comment if this helped you speed up your 4G WiFi, with a screenshot of your (hopefully improved) internet speed.
Don’t just go by the signal indicators on your router when deciding on the best location for your device. A location with higher SINR and only 3/5 bars will have a much higher impact on your dload/upload speeds than a location with low SINR and 5/5 bars.
