Question
Which of the following technologies utilizes millimeter wave to achieve high data rates?
Options
- A802.11ac
- BZ-Wave
- CNFC
- D5G
Explanation
5G technology specifically utilizes millimeter wave (mmWave) frequencies in its higher frequency bands to achieve extremely high data rates and low latency, especially in urban areas.
Common mistakes.
- A. 802.11ac is a Wi-Fi standard that operates in the 5 GHz band, which is microwave, not millimeter wave.
- B. Z-Wave is a wireless protocol primarily used for home automation, operating on low-frequency radio waves (e.g., 908.42 MHz in the US), not millimeter wave.
- C. NFC (Near Field Communication) is a short-range wireless technology that operates at 13.56 MHz, which is very low frequency and not millimeter wave.
