5G

The IEEE 802.3 is a collection of standards for:

Wired Ethernet

The naming conventions for Ethernet standards provide valuable information about the technology. The number at the beginning of the standard name indicates the speed in megabits per second (Mbps) or gigabits per second (Gbps). The "BASE" part in the middle signifies baseband transmission, meaning the entire bandwidth of the medium is used for a single data channel (as opposed to broadband, which divides the bandwidth into multiple channels enabling simultaneous transmission of different types of data). For faster Ethernet standards offering gigabit speeds, "GBASE" is often used instead. The suffix at the end indicates the type of cabling and its characteristics. For example, "T" stands for twisted-pair copper cabling, "CX" refers to short-range copper connections, typically using twinaxial cables, while "CR" also denotes copper-based direct attach cables, often using twinax for short-range high-speed connections, com

True

While most Ethernet standards include a suffix indicating the cabling type, coaxial standard names like 10BASE2 and 10BASE5 do not explicitly mention the cable type in their names. However, these standards are also known by their more common names, such as "ThinNet" and "ThickNet". In the case of 10BASE2 ("ThinNet"), the name denotes a wired Ethernet standard providing 10 Mbps speed over thin coaxial cable, whereas 10BASE5 ("ThickNet") refers to a wired Ethernet standard providing 10 Mbps over thick coaxial cable.
