|Data Throughput - LTE - RLC Factors|
Details would come later
Example 1 > PHY throughput and RLC Throughput in a drive test
Following plot is from the data captured by a drive test tool Azenqos Drive Test tool (AZQ Android) . I got the log captured by the tool and exported the data as csv file and then plot it on Microsoft Excel. This is a log captured from downloading a big file.
Just from this single capture, it is hard to understand how each of the RLC parameters influencing the final throughput. But I want to show you overall correlation between RLC throughput and Physical layer throughput.
Overall trend that you can easily notice and is easily understandable is
One thing I found strange (interesting) in this example is
One thing that may interest you (I am not saying this is abnormal.. just to let you see the plot in more detail)
