How will the use of frequencies change?

Today, the frequency spectrum used by 2G, 3G and 4G is between 800 MHz and 2600 MHz (2.6 GHz). 5G will be activated on frequencies very close to the current frequencies: 700 MHz and 3600 MHz (3.6 GHz). Low frequencies (700-800 MHz) allow better signal penetration, unlike higher frequencies (3.6 GHz) which offer a higher capacity and speed but less coverage. That is why, for example, WiFi at 5 GHz does not propagate as well in homes as WiFi at 2.4 GHz.
