Generate QuizGK Question
Which frequency band offers better building penetration for mobile signals?
- 26 GHz
- 3.5 GHz
- 700 MHz
- 1800 MHz
Answer: 700 MHz
Lower frequency bands (like 700 MHz) have longer wavelengths that penetrate buildings and obstacles better, providing wider coverage with fewer towers. Higher bands (3.5 GHz, 26 GHz) offer higher capacity but shorter range, requiring denser infrastructure. 5G deployments use band combinations for coverage+capacity.
