What does 100BASE-T4 mean in NETWORKING

100BASE-T4, or IEEE 802.3u, is an Ethernet standard that uses four-pair Category 3 Unshielded Twisted Pair (UTP) cables to deliver data at speeds up to 100 Megabits per Second (Mbps).

100BASE-T4 transmits data at up to 100 Mbps, making it one of the fastest Ethernet standards on the market today.

The network cabling used with this standard are Category 3 Unshielded Twisted Pair (UTP) cables. These cables are most commonly referred to as "Ethernet cables".

No; while fiber optic networks can achieve even higher speeds, they typically require more expensive hardware and installation costs than traditional Ethernet networking. With Ethernet networks such as those using the 100BASE-T4 standard, copper wires are used instead of fiber optics.

In order for devices to communicate over your Ethernet network, yes they must be compatible with the same standard you're using. If you have brand new equipment but some older devices as well, make sure they all support the same version of Ethernet or else your connection may not function properly.

Yes, your router must support this standard in order for it to send and receive traffic over your network at the speeds associated with this technology. If you're looking for faster speeds or more reliable connections nowadays then you should look into newer technologies such as Gigabit or 10 Gigabit Ethernet solutions.

Generally speaking no; while different media types have different limitations on how far signals can travel before becoming distorted or corrupted, UTP cabling used in this type of connection should be relatively unaffected by distances up to around 300 meters (984 feet). Anything longer than that may require additional hardware or special mitigation techniques in order to maintain reliable connectivity.

It's possible; depending on what grade of UTP cable is currently installed in your walls and other areas where wiring may exist, it's possible that these could meet the requirements needed for a successful connection. However, since wiring grade can degrade over time it's recommended that if you intend to re-use existing infrastructure with a new high speed network, then first check if it meets current industry standards before attempting any kind of data transfer over this system.

While there are certain exceptions in which two incompatible devices may successfully connect due to commonality amongst other protocols running within them, by and large if two pieces of equipment are not compliant with each other regarding the media type being used then data will not successfully transfer between them. As such, when attempting any kind of connection across disparate networking components make sure they follow IEEE 802.3u specifications beforehand.

It's mostly dependent on how securely your system is configured; though UTP itself does provide some inherent shielding from outside interference and malicious actors attempting access via physical proximity methods (such as tapping into wires), proper precautions still need to be taken regardless at both layer 2 & 3 levels in order for maximum protection against security threats like denial of service attacks and so forth.
