Which frequency range is commonly referred to as the "millimeter wave" spectrum in 5G?

  1. Below 1 GHz

  2. 1-6 GHz

  3. 6-100 GHz

  4. Above 100 GHz


Correct Option: C
Explanation:

The millimeter wave spectrum in 5G typically falls between 6 and 100 GHz, offering higher bandwidth and faster speeds but with limited range and penetration.

What is the primary advantage of using higher frequency bands in 5G compared to lower frequency bands?

  1. Increased coverage

  2. Enhanced security

  3. Higher capacity and data rates

  4. Reduced latency


Correct Option: C
Explanation:

Higher frequency bands in 5G provide significantly higher bandwidth, enabling much faster data rates and increased network capacity to support more devices and applications.

Which frequency band is commonly used for low-band 5G deployments?

  1. 600 MHz

  2. 2.5 GHz

  3. 28 GHz

  4. 39 GHz


Correct Option: A
Explanation:

The 600 MHz band is widely used for low-band 5G deployments due to its good coverage and penetration characteristics, making it suitable for rural and suburban areas.

What is the main challenge associated with using millimeter wave spectrum in 5G?

  1. High cost of infrastructure

  2. Limited range and penetration

  3. Increased interference

  4. Security vulnerabilities


Correct Option: B
Explanation:

Millimeter wave spectrum has limited range and penetration compared to lower frequency bands, making it more susceptible to blockages and requiring denser network infrastructure.
