> stream videos, play online games or work in virtual offices. This requires a great deal of bandwidth only the first might if someone were streaming 8K video with 7.1 lossless audio, which wouldn't even come close to 1.2Gbps, but on a mobile device on public transport? no I'm pretty certain 1.2Gbps would serve an entire train 720p video with 128kbps stereo audio, which for 99.9% of people would be adequate for a mobile device on public transport it's a bit like breaking the land speed record, a bit pointless and you'll never get (nor need) to be the driver
