Study Notes

5G technology will go beyond human communications and enable the future of intelligent IoT.
5G supports three scenarios: eMBB, URLLC, and mMTC, each with differentiated applications.
eMBB offers enhanced mobile broadband with high rates (e.g., 8-GB movie download in 3s) and supports services like AR/VR, autonomous driving, and cloud gaming.
URLLC requires ultra-reliable low-latency communication (less than 10 ms), supporting applications such as remote surgery, human-robot collaboration, and autonomous driving.
mMTC supports massive machine-type communications (up to 100 billion connections by 2025) and applications like smart cities, smart agriculture, and logistics.
IoT, an emerging technology, is interconnecting everything, and industries, agriculture, education, healthcare, transportation, energy, financial information, and the environment and home are widely using smart devices.
IoT requires strong connectivity (5G's capability of 1 million connections per km2), and smart devices include greenhouses, smoke detectors, and manhole covers.
5G performance objectives include latency, throughput, and connections.
3GPP, a standardization organization, has developed 3G, 4G, and 5G technologies, and 5G starts from release 15, with 5G NR and Next Generation Core.
5G networking architecture includes non-standalone and standalone options, and gNodeBs and eNodeBs coexist in early and middle stages.
The 5GC is introduced in the middle and late stages, and eNodeBs gradually withdraw from the network.
The text references ITU-R M.2083, 3GPP, and ITU as sources.
