China has started to roll out what it’s calling the world’s most advanced internet network, which promises to operate several times faster than current networks.

The network – which can travel at about 1.2 terabits (or 1,200 gigabits) each second – is fast enough to transfer data from 150 movies in one second, according to Chinese tech manufacturer Huawei.

Those represent theoretical speeds that won’t appear at consumers’ homes anytime soon. But a more robust, faster internet service has broad implications for businesses, faster information transfers, stock trading advantages and other national security implications.

In a press conference this week, Huawei and China Mobile officially launched the country’s next-generation backbone network, in partnership with Beijing’s Tsinghua University and Cernet, an education and research network funded by the Chinese government. A backbone network is network infrastructure that moves internet traffic to different geographic locations, and can support hungry-data transfers from technologies such as 5G and electric vehicles.
