1. What is New Cell Radius?

New Cell Radius is half of the original radius. In this the cell boundaries need to be revised so that the local area can now contain number of smaller cell, these new cells are called microcells.

2. How Does the Calculator Work?

The calculator uses the New Cell Radius formula:

Where:

• \( r_{cn} \) — New Cell Radius (m)
• \( r_{co} \) — Old Cell Radius (m)

Explanation: The formula calculates the new cell radius by dividing the old cell radius by 2, creating smaller microcells for improved network capacity and coverage.

3. Importance of Cell Radius Calculation

Details: Accurate cell radius calculation is crucial for cellular network planning, optimizing coverage areas, increasing network capacity, and improving signal quality in telecommunications systems.

4. Using the Calculator

Tips: Enter the old cell radius in meters. The value must be valid (radius > 0).

5. Frequently Asked Questions (FAQ)

Q1: Why divide the cell radius by 2?
A: Dividing the cell radius by 2 creates smaller microcells that can handle more users and provide better coverage in high-density areas.

Q2: What are the benefits of smaller cell radii?
A: Smaller cells increase network capacity, improve signal quality, reduce interference, and provide better coverage in indoor and dense urban environments.

Q3: When should cell splitting be considered?
A: Cell splitting should be considered when existing cells become congested, when user density increases, or when better coverage is needed in specific areas.

Q4: Are there limitations to cell splitting?
A: Cell splitting requires additional infrastructure, increases handover frequency, and may require more complex network management and frequency planning.

Q5: How does cell radius affect network capacity?
A: Smaller cell radii allow for frequency reuse across more cells, significantly increasing overall network capacity and supporting more simultaneous users.
