Fast is more than a speed test
Bandwidth, delay, variation in delay and packet loss describe different parts of network quality.
In 30 seconds
- Bandwidth is a capacity; throughput is the achieved transfer rate.
- Latency measures delay; jitter describes its variation.
- Record where, when and how you measured before comparing results.
Make it concrete
A download can finish quickly while a call still breaks up. Compare packet loss and jitter as well as Mbps.
- 01Capacity
- 02Delay
- 03Consistency
Check your understanding
Can two links with the same Mbps feel different during a video call?
- Bandwidth is a capacity; throughput is the achieved transfer rate.
- Latency measures delay; jitter describes its variation.
- Record where, when and how you measured before comparing results.
