How to Use the Calculator

The Erlang and Grade of Service Calculator helps you determine the Grade of Service (GoS) in telecommunication systems based on the traffic intensity and the number of channels available.

  1. Enter the total traffic intensity in Erlangs in the "Traffic Intensity (Erlangs)" field.
  2. Enter the number of channels or trunks available in the "Number of Channels/Trunks" field.
  3. Click the "Calculate" button to compute the Grade of Service (GoS).
  4. The result will be displayed in the "Grade of Service (GoS)" field.

Understanding the Grade of Service (GoS)

The Grade of Service (GoS) is a measure of the probability of congestion or blockage in a communication system. A lower GoS indicates a higher level of service quality, meaning fewer calls are likely to be blocked or dropped.

The formula used to calculate the GoS is based on the Erlang B formula, which is commonly used in teletraffic engineering to determine the probability of call blocking in a loss system.
