In cellular mobile communication networks, what is the typical cell coverage radius of a microcell?
Multiple Choice Options
- A
10 - 50 km
- B
1 - 30 km
- C✓ Correct Option
0.1 - 1 km
- D
10 - 100 m
Detailed Technical Solution & Explanation
Cellular network cell hierarchy is categorized by coverage radius and base station transmit power:
•
Macrocells: Large coverage areas with radius ranging from 1 km to 20+ km (rural and suburban environments).
•
Microcells: Medium coverage areas with radius ranging from 100 meters to 1 km (0.1 to 1 km), typically deployed in dense urban streets, commercial corridors, and malls with high user density.
•
Picocells: Small coverage areas with radius from 10 meters to 100 meters (indoor office buildings, transit hubs).
•
Femtocells: Very low-power residential base stations covering < 10 meters.
Option Analysis:
•
Option A (10 - 50 km): Incorrect; represents large rural macrocells or satellite cells.
•
Option B (1 - 30 km): Incorrect; typical macrocell range.
•
Option C (0.1 - 1 km): Correct; microcells standardly span between 100 meters (0.1 km) to 1 km.
•
Option D (10 - 100 m): Incorrect; typical range for picocells and femtocells.
