1. What is Offered Load?

Offered load refers to the amount of data or traffic that is generated by users or devices within a wireless network. It represents the total demand placed on the network resources during a specific time period.

2. How Does the Calculator Work?

The calculator uses the Offered Load equation:

Where:

• \( A \) — Offered Load (erlangs)
• \( Q_i \) — Maximum Calls Per Hour Per Cell (calls/hour)
• \( T_{avg} \) — Average Calling Time (seconds)

Explanation: The equation calculates the total traffic load by multiplying the maximum number of calls per hour by the average call duration, then dividing by 60 to convert to erlangs.

3. Importance of Offered Load Calculation

Details: Accurate offered load calculation is crucial for network capacity planning, resource allocation, and ensuring quality of service in wireless communication systems.

4. Using the Calculator

Tips: Enter Maximum Calls Per Hour Per Cell in calls/hour and Average Calling Time in seconds. All values must be valid positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is an erlang?
A: An erlang is a unit of telecommunications traffic measurement. One erlang represents one hour of continuous use of one traffic path.

Q2: How does offered load relate to network capacity?
A: Offered load helps determine the required network capacity to handle the expected traffic without congestion or service degradation.

Q3: What factors affect offered load?
A: User behavior, time of day, special events, and service offerings can all significantly impact the offered load on a network.

Q4: How is offered load used in network design?
A: Network designers use offered load calculations to determine the number of channels needed, cell sizing, and overall network architecture.

Q5: What's the difference between offered load and carried load?
A: Offered load is the total traffic attempting to use the network, while carried load is the traffic that actually gets through successfully.
