### A. 5G Overview
5G wireless technology is meant to deliver higher multi-Gbps peak data speeds, ultra low latency, more reliability, massive network capacity, increased availability, and a more uniform user experience to more users.

Enhanced mobile broadband (eMBB): 5G is expected to provide much faster and more reliable mobile broadband, offering consumers a richer application experience. Ultra-reliable and low latency communications (URLLC): The highest priorities for this usage scenario are latency and mobility parameters. Massive machine-type communications (mMTC): This usage case is characterized by very large-scale or massive applications of the Internet of Things (IoT).

### C. 4G to 5G

4G is Communication Oriented, and 5G is Service Oriented.

While services like smart-parking meters value high reliability and security are more forgiving with respect to latency, others (like driver-less cars) may need ultra-low latency (URLLC) and high data speeds. Network slicing in 5G supports these diverse services and facilitates the efficient reassignment of resources from one virtual network slice to another.
The applications that are enabled or enhanced by the 5G need greater bandwidth, more connections and lower latency than was achievable with previous generations. Each use case will have its own unique performance requirements, making the one-size-fits-all approach to service delivery obsolete.

### D. RAN Architecture

A 5G Radio Access Network (RAN) uses 5G radio frequencies to provide wireless connectivity to devices to deliver these incredible applications. In order to deliver these use cases, the Radio Access Network consists of antennas, radios, baseband (RAN Compute), and RAN software to enable incredible speeds and mobility.

D-RAN : Distribute RAN
C-RAN : Centralized RAN
vRAN : C-RAN/O-RAN (Cloud RAN)
