Erlang Loss Formula Calculator

Formula

The formula to calculate the Erlang Loss (E) is:

\[ E = \lambda \cdot h \]

Where:

(E) is the Erlang Loss (calls)
(λ) is the call arrival rate (calls/min)
(h) is the average call-holding time (min)

What is Erlang Loss?

The Erlang Loss Formula is used to calculate the number of calls in a telecommunications system. It helps in understanding the traffic load and the capacity required to handle calls efficiently.

Example Calculation

Let's assume the following values:

Call Arrival Rate (λ) = 10 calls/min
Average Call-Holding Time (h) = 2 minutes

Using the formula:

\[ E = 10 \cdot 2 = 20 \text{ calls} \]

The Erlang Loss (E) is 20 calls.
