What is 5G?

5G is the fifth generation of mobile network technology, offering much faster speeds, lower lag (latency), and the ability to connect far more devices at once than 4G. It powers faster phones and many Internet-of-Things uses.

Key things to understand

  • 1Much faster data speeds than 4G, with very low latency.
  • 2Can connect huge numbers of devices in a small area.
  • 3Uses higher-frequency radio bands (shorter range, more towers).
  • 4Enables real-time uses: AR/VR, smart cities, connected machines.

Frequently asked questions

How is 5G different from 4G?
5G is faster, has lower latency, and connects many more devices, using higher-frequency radio bands.
Is 5G dangerous?
No credible evidence shows harm at the low power levels used; it's non-ionizing radio, like earlier networks.
Why does 5G need more towers?
High-frequency 5G has shorter range, so more small-cell towers are needed for coverage.
