CAT5e (category 5 enhanced) is a network cable that was widely installed in buildings around the turn of the century. It reaches speeds of up to 1 Gbit/s.
For a workstation with a laptop that is often still enough. But modern access points can process more data than a CAT5e cable can carry. The cable then becomes the bottleneck of the network.
During a refurbishment, CAT5e is therefore often replaced by CAT6 or CAT6A.
What does this mean for the IT-Label?
Cabling falls under the Infrastructure component. The official level descriptions mention CAT6 for IT2 and CAT6A or higher for the top levels. With CAT5e, a high label is therefore difficult. Under Scalability, older cabling also counts against you, because it leaves less room for growth. See CAT6 and CAT6A.
