Glossary

The part of a network that interconnects different networks and sites of a network provider.

The part of a 5G network that connects the centralized units (CU) of the radio network to the core network of the provider.

The range of frequencies within a given band, in particular that used for transmitting a signal.

A device in a mobile telecom network that transports a baseband frequency, usually from a remote radio unit to the network core.

Also known as symbol rate, is the number of symbol changes, waveform changes, or signaling events across the transmission medium per unit of time. If the system is using a modulation scheme with precisely two symbols, then the baud rate and the bit rate are the same. However, if each symbol represents more than one bit, the baud rate can be less than the bit rate​.

A system of telecommunication companies, led by the Bell Telephone Company (which later became AT&T), that dominated the telephone services industry in North America until its antitrust breakup in 1983.

Packaging that places the chip connections under the chip package, allowing more efficient use of space in circuit boards, a smaller package size, and better soldering.

The number of bits that are conveyed or processed per unit of time. In the context of digital communication, it is typically measured in bits per second (bps) and represents the total number of physically transferred bits over a communication link, including both the useful data and any other bits used for protocol overhead

A common measure of data speed for telecommunications equipment and links.

Existing network links or infrastructure that may need upgrading or integration with new technologies or equipment.
