Climbing aboard the high-speed train, Huawei engineer Shen Lie Jun takes a black GPS unit with a red flashing light out of his backpack and places it on the windowsill. He puts the laptop on a seat and crouches on the floor as the train glides silently out of the station. Rain streaks horizontally across the window as we pick up speed. Shen clicks on a file and begins to download over a Long Term Evolution, or LTE, wireless network that Huawei has built over the track. As the train clocks 170 kilometres per hour, the download speed has already hit 43 megabits per second, way faster than the LTE networks Bell and Rogers have just built in small, urban parts of Canada. “The bandwidth is limited by China Telecom,” Shen says. “The max we can go up to is 46.1.” The train is now going 300 kilometres per hour; leafy industrial parks flit by the window. Shen points to a visualization of the GPS, which shows his download signal switching seamlessly between two wireless towers. The train rocks back and forth as it reaches its maximum speed of 431 km/h, but Shen’s download speed is still wavering between 43 and 44.9 mbps...
