5G characteristics

Ultra high speed

20 times faster than maximum 4G download speeds.

Massive connectivity

The number of smart devices that can be connected simultaneously is more than 100 times greater than 4G can achieve.

Ultra-low latency

Latency of less than one-thousandth of a second.

Three major 5G frequency bands

Global and Hong Kong 5G spectrums are broadly divided into three different frequency bands – high, medium and low. Each range comes with completely different characteristics and advantages.

High-band spectrum


UHF broadband for ultra-high transmission speed.

Deployment in the environment

This is suitable for indoor and high-density environments, and provides ultra high-speed connectivity for multiple users simultaneously.

Mid-band spectrum
3.3GHz, 3.5GHz
and 4.9GHz


Considered 5G’s “golden band spectrum”, mid-band provides high speeds and wide coverage.

Deployment in the environment

5G service will be rolled out to many Hong Kong districts.

Low-band spectrum
2GHz and below


Very high penetrating signal power to suit Hong Kong’s proliferation of high-rise buildings.

Deployment in the environment

Use high and medium frequencies to maximize 5G coverage.
