Propagation Delay Calculator

Formula

The formula to calculate the propagation delay is:

\[ PD = \frac{B - A}{S} \]

Where:

\( PD \) is the propagation delay (s).
\( B \) is the position of router B (m).
\( A \) is the position of router A (m).
\( S \) is the propagation speed (m/s).

Example

Let's say the position of Router A (A) is 1000 m, the position of Router B (B) is 5000 m, and the propagation speed (S) is 299,000,000 m/s. The propagation delay would be calculated as follows:

\[ PD = \frac{5000 - 1000}{299000000} \approx 0.0000134 \text{ s} \]

So, the propagation delay is approximately 0.0000134 seconds.

What is Propagation Delay?

A propagation delay is defined as the delay in a broadcasted signal due to the distance between two different routers or receivers. It is an important factor in network performance and is influenced by the medium through which the signal travels.
