Question 1

True or false: 5G requires completely new phone hardware because it uses a different radio frequency.

Accepted Answer

False. Many 5G phones use modems that support both 4G and 5G; older 4G-only phones simply lack the necessary chip.

Question 2

True or false: 5G radiation is proven to cause COVID-19 according to scientific studies.

Accepted Answer

False. No credible study links 5G to COVID-19; this is a debunked conspiracy theory spread via social media.

Question 3

True or false: The first commercial 5G network was launched in South Korea in 2019.

Accepted Answer

True. South Korea’s SK Telecom and KT rolled out the world’s first commercial 5G services in April 2019, ahead of the US.

Question 4

True or false: 5G signals can travel farther than 4G signals without losing strength.

Accepted Answer

False. Higher-frequency 5G signals actually have shorter range and are more easily blocked by buildings, trees, and rain.

Question 5

True or false: 5G networks can operate on millimeter wave frequencies above 24 GHz.

Accepted Answer

True. 5G uses high-frequency millimeter waves for ultra-fast speeds, but they have short range and require dense infrastructure.

Question 6

True or false: 5G networks can reduce latency to under 1 millisecond in ideal conditions.

Accepted Answer

True. Ultra-low latency (as low as 1 ms) enables real-time applications like remote surgery and autonomous driving.

Question 7

True or false: 5G networks can theoretically support up to 1 million devices per square kilometer.

Accepted Answer

True. 5G’s massive IoT capability allows 1 million connected devices per sq km, enabling smart cities and dense sensor networks.

Question 8

True or false: 5G beamforming technology focuses signals directly to users instead of broadcasting everywhere.

Accepted Answer

True. Beamforming directs a focused signal toward a specific device, improving efficiency and reducing interference.
