downJitter property
Downlink data packet jitter (ms) refers to the stability of data communication in the user's current network environment. The smaller the value, the better. The normal value range is 0ms - 100ms. -1 means that the speed test failed to obtain an effective value. Generally, the Jitter of the WiFi network will be slightly larger than that of the 4G/5G environment.
