How fast might your mobile phone network be in the future?

According to Science Daily, 5G tests are expected to start in 2019 in the US and by 2020 in the UK. China has already tested 5G in10 big cities and announced the start of 5G this year.

As a result of the increased size of networks, data transfer will be much faster and more reliable.5G is expected to be 10 to 100 times faster than the average speed of the current 4G network. It may enable many new uses that are impossible on older networks. For example, you can download a film within just 3 seconds. This used to take a few minutes with a 4G network. In addition, there will be enough capacity(容量) for everyone to chat on social media and watch movies on their phones.
