Bandwidth is the capacity of a connection: how much data can pass through it per second. You see it expressed as Mbit/s (megabits per second) or Gbit/s (gigabits per second). 1 Gbit/s is 1000 Mbit/s.
More bandwidth means more people can do data-heavy tasks at the same time, such as video calls or sending large files. But bandwidth is not the only thing that counts. A connection can have plenty of capacity and still feel slow because of high latency.
Also note the difference between download and upload. With a symmetrical connection they are the same.
What does this mean for the IT-Label?
Bandwidth falls under Connectivity, where capacity and speed are assessed. Under Performance, the audit measures how much of it you actually get under real load. High bandwidth on paper does not automatically lead to a high label. Latency and stability count too. And under Scalability, the audit checks whether capacity can grow.
