An engineer has deployed Cisco Aironet 3800 Series APs with switches that support 802.11bz on existing CAT-5e cabling. Which value is the maximum distance supported to achieve up to 5 Gb speed?
IEEE 802.3bz (mGig or N-BASET) can be used on CAT5e cabling up to 100 meters long. This standard allows for speeds of 2.5 Gbps and 5 Gbps on existing twisted-pair copper cabling
According to Ethernet standards, the maximum length of a Cat5e cable run is 100 meters (or 328 feet). It is possible to go further by using a POE repeater.
An engineer has deployed Cisco Aironet 3800 Series APs with switches that support 802.11bz on existing CAT-5e cabling. Which value is the maximum distance supported to achieve up to 5 Gb speed?
When deploying Cisco Aironet 3800 Series APs with switches that support 802.11bz on existing CAT-5e cabling, the maximum distance supported to achieve up to 5 Gb speed is 30-50 meters
Keep lengths of CAT-5e between 30-50m or below when using dense cable bundles; for example, cables in a dense area like a pipe or places where five or more cables are tied in a bundle.

On the third page in the table at the bottom, it says the cable length should be between 30-70m.
