A user wants faster Wi-Fi throughput for streaming video and is less concerned about range, since the device is close to the router. Which frequency band should the user select?
- A5 GHz
- B2.4 GHz
- C433 MHz
- D900 MHz
Show answer & explanationAnswer & explanation
Correct answer: A. 5 GHz
The 5 GHz band offers higher data throughput and less interference from common household devices than 2.4 GHz, but has a shorter range. Since the device is close to the router, range is not a concern, making 5 GHz the better choice for streaming performance.
Why the other options are wrong
- B. 2.4 GHz has longer range but slower speeds and more interference.
- C. 433 MHz is not a standard Wi-Fi frequency band.
- D. 900 MHz is not a standard Wi-Fi band used for this purpose.
Wi-Fi Frequency Bands
2.4 GHz offers longer range but slower speeds and more interference; 5 GHz offers faster speeds with shorter range and less interference.
- 2.4 GHz: longer range, more interference
- 5 GHz: faster speeds, shorter range
- Dual-band routers support both
- 6 GHz added in Wi-Fi 6E for even faster speeds
Memory trick: 2.4 GHz travels far like a marathon runner; 5 GHz sprints fast but tires quickly.
