Introduction
The Erlang Loss Formula Calculator is a handy tool for calculating the Erlang loss in a telecommunication system. It helps you determine the number of calls that are blocked or lost due to congestion in a network. To use this calculator, you need to input the call arrival rate (calls per minute) and the average call-holding time (in minutes). The calculator will then provide you with the Erlang loss in terms of calls.
How to Use
To use the Erlang Loss Formula Calculator, follow these simple steps:
- Input the call arrival rate (calls per minute) into the designated field.
- Input the average call-holding time (in minutes) into the designated field.
- Click the “Calculate” button to perform the calculation.
- The Erlang loss in terms of calls will be displayed on the screen.
Formula
The Erlang Loss Formula is expressed as:
Where:
Eis the Erlang loss in calls.lis the call arrival rate in calls per minute.his the average call-holding time in minutes.
Example
Suppose the call arrival rate is 60 calls per minute, and the average call-holding time is 0.5 minutes. Using the Erlang Loss Formula Calculator, the Erlang loss would be calculated as follows:
FAQ’s
Q1: What is Erlang loss?
A1: Erlang loss is the number of calls that are blocked or lost in a telecommunication system due to network congestion.
Q2: What is the call arrival rate?
A2: The call arrival rate is the number of calls received per minute in a telecommunication system.
Q3: What is the average call-holding time?
A3: The average call-holding time is the average duration a call is active before it is terminated.
Conclusion
The Erlang Loss Formula Calculator is a useful tool for network planners and telecommunications professionals to estimate the impact of congestion on call quality and availability. By inputting the call arrival rate and average call-holding time, you can quickly determine the Erlang loss in terms of calls, helping to optimize your network for better performance.
