If you thought 5G was developed to give your smartphone faster internet, you're wrong — and by a wide margin.

Yes, the jump in peak speeds from 150 MB/s to 20 GB/s means you'll enjoy significantly better browsing, but the real story is something else entirely.
The video shows the cargo port of Guangzhou, China.
What makes it remarkable is that crane and truck operators work remotely from an air-conditioned office, with control running entirely over a 5G network.

5G's greatest advantage is near-zero latency.
When you're remotely operating a crane carrying a container weighing several tons, even the slightest delay between your input and the response on the ground is dangerous.
With latency that is virtually imperceptible, remote crane operation feels almost as natural as sitting in the cab itself.
5G offers additional advantages that are on full display at the port of Guangzhou.
5G's wide frequency bandwidth allows a massive number of endpoints to connect to the network simultaneously within a small cell — far more than a 4G network can support.
The 5G network at the port is private, and the spectrum is divided into distinct bands for trucks, cranes, and so on, distributing the network load across different frequencies.

5G networks feature a greater number of antennas, data processing takes place at relay stations rather than at a central hub (edge computing), and radio signals are beamformed — directed precisely at the receiving device rather than broadcast in all directions.
The combination of all these advantages enables high speeds and low latency, even if it comes at the cost of deploying more antennas per cell.
5G technology opens a world of opportunities for industries that depend on wireless communication — autonomous vehicles, for example — and this port is only the opening shot.
