How to Use This Calculator
- Enter the link distance and select the transmission medium (free space, fiber, coax, or microwave).
- Enter data rate (Mbps) and packet size (bytes) if transmission delay is also needed.
- Review propagation delay in ms and us and transmission delay in us.
- Use total one-way delay for latency-sensitive applications like VoIP, trading, and video conferencing.
