Thankfully, jitter is incredibly easy to spot. Just like with Packet Loss, jitter will result in jumbled calls with words or sentences out of order, and speakers interrupting each other. But, just like with latency, there is a direct way to measure jitter within a network.
This is where our speed test will actually come in handy, because it can directly measure jitter.
From here, you can form a better understand of exactly what your internet is capable of: download and upload speeds are direct indicators of how quickly your connection can receive or transmit data, as well as the delay and jitter caused by that delay.
