Originally convened to establish standards for 3G technology, the 3GPP is one of the primary groups working on new standards for 5G technology. 5G New Radio (NR) Global air interface standard for 5G networks developed by the 3GPP. "Phase 1" was published in Release 15 with "Phase 2" coming in Release 16. Beamforming Technique by which base stations can identify the most efficient route to a user. Beamforming is used together with massive MIMO arrays to send individual data packets in a precisely coordinated pattern allowing many users and antenna to exchange more information while reducing interference for nearby users. Cloud Radio Access Network (cRAN) cRAN is a cloud computing-based architecture for radio access networks that supports existing and future wireless communication standards. The idea is that pooling resources in the cloud will create more efficient mobile networks by moving baseband processing from the device level to the cloud. Critical Communications (CriC) One of the three primary subsets of 5G use cases focused on applications that need immediate responsiveness with near zero latency. The amount of data may be small, but it must to be transmitted and received in as close to real time as possible. An example is medical surgery robotics. Enhanced Mobile Broadband (eMBB) One of the three primary subsets of 5G use cases offering faster data speeds and better coverage than previous wireless standards. Examples include augmented and virtual reality. Latency The time delay between a request for data or action and the response. Massive Machine-Type Communication (mMTC) One of the three primary subsets of 5G use cases specifically designed to handle vast amounts of data generated by various sensors networks and devices. The target for this use case is the Internet of Things. Massive Multiple Input/Multiple Output (MIMO) Wireless communication technology in which multiple antennas are used at the source and destination, and their functions (transmit/receive) are combined to reduce errors and optimize data speed. mmWave The band of spectrum between 30GHz and 300GHz. Also known as extremely high frequency (EHF). Network Slicing 5G Network Slicing enables operators to build virtual networks tailored to specific application requirements. Each portion of the overall network receives optimized resources and network topology for a particular use case. Small cell densification Small cells are a type of base station that include femtocells, picocells, microcells, and metrocells. Small cells are low powered access devices with a typical coverage range of 10m to 300m. Placement of small cells every few hundred meters creates a dense and flexible network for a small but perhaps vital geographic area. Small cell densification will be critical to support the nMTC use case. Tactile internet The International Telecommunication Union (ITU) defines the Tactile Internet as an internet network that combines ultra low latency with extremely high availability, reliability, and security. It is projected to be the next evolution in the Internet of Things that will enable control of the IoT in real time and include more human to machine interface. RF Glossary
