It will also provide the units of measurement in Mbps for data transfer rates and in milliseconds for latency and jitter. The results of the speed test will help you determine whether your Internet connection is suitable for tasks such as surfing the web, making video calls, watching online videos or downloading files. A good result on a home network is 50Mbps or more downstream and 10Mbps or more upstream, while on 4G mobile networks speeds of 50Mbps or more downstream and 20Mbps or more upstream are achieved.
