Hello Nokia Experts.

Is there a KPI available for tracking timing advance (TA)?

I’d like to create a chart with time on the x-axis and distance on the y-axis.

Thank you!

For LTE, there is a counters like TimingAdvance, where you might have distributions or even average TA values.

You can plot it in Excel or if you have a Python skill so use the library.

If I am not wrong so it is mathplotlib.

Yes TA counter there.

You can use seaborn or mathplotlib to create plot for analysis, as menitoned.

I am not an expert in Nokia, but in Ericsson and Huawei you have several counters that indicate ranges of distances.

You would have to look up what those counters are called in Nokia.

So if you want to analyze overshooters, you should have ranges on the X-axis, for example, (0 to 500m), (500 to 1000m)…, and the number of samples on the Y-axis.

This way, you can see where your samples are concentrated and start optimizing.

Hello All: Thanks all for your anwsers

I’ve done it on Excel and got this result:

But I am looking for something like this:

My question is:
Is there an equation to get TA by combinig all these ranges ?

Follow TA Excel example (sample data), maybe you can ajust to your counters.
