Bandwidth Delay Product Calculator

This page explains the bandwidth delay product calculator and formula. This term is commonly used in data communication for both wireless and wired systems.

What is Bandwidth Delay Product?

The bandwidth delay product represents the number of bits (or bytes) that can be transmitted before an acknowledgment (ACK) is received from the other end. Essentially, it estimates the number of bits “in transit” through the transmission medium.

Inputs

Outputs

The following calculator helps determine the bandwidth delay product for any wired (e.g., DSL, ADSL, LAN) or wireless system (satellite, terrestrial, HSDPA).

EXAMPLE:

  • INPUTS:

    • Bandwidth = 512e3 (i.e., 512 kbits per second)
    • Delay = 1000e-3 (i.e., 1000 ms)
  • OUTPUT:

    • Bandwidth delay product = 512 kbits
    • Bandwidth delay product = 64 Kbytes
