Cellular Wireless Networks (7COM1031)

•  Cellular networks are a type of wireless mobile network.
•  Principles of cellular networks were discussed.
•  Generations of cellular technology include: - 1G (AMPS) - 2G (GSM, TDMA and IS-95, CDMA) - 4G (WiMAX and LTE, OFDM) - 5G
•  5G technology is the next major phase of wireless communications.
•  5G is expected to be 10 times faster than 4G.
•  5G is expected to have a speed of 1Gbps.
•  The cost of 5G is expected to be lower.
•  5G technology is a convergence of nanotechnology, cloud computing, and all-IP platforms.
•  5G uses nanotechnology between 0.1 and 100nm to control the structure of matter.
•  5G uses software-defined networking (SDN) and Network Functions Virtualization (NFV).
•  5G architecture is service driven, and network slicing is used for on-demand deployment.
•  The RAN (Radio Access Network) uses cloudRAN architecture.
•  RAN utilizes non-real time and real-time resources with on-demand deployment.
•  5G has better data bandwidth (1Gbps or higher) and dynamic information access, available at low cost.
•  5G offers high-quality services (QoS).
•  5G allows pages to load almost instantly and supports various interactive multimedia services (voice, streaming video, Internet, and other broadband).
•  5G is expected to revolutionize the wireless market and is user-centric.
•  5G is a promising generation of communication that will change people's lives.
•  5G data transfer architecture involves a Flat IP network, concept providers, and global concepts.
•  The RAN uses a Flat IP network to enable various communication technologies.

5G Network Layers

•  Open Wireless Architecture (OWA) combines Physical and Data Link Layer.
•  Network Layer is subdivided into lower and upper network layers.
•  Network layer routes data from source to destination.
•  Open Transport Layer (OTL) combines the functionalities of Transport and Session layers.
•  Application Layer formats the data, decrypts encrypted data, and selects the best wireless connection for a given service.

RAN (Radio Access Network) Architecture

• Radio Access network (RAN) is part of mobile telecommunication system.
•  RAN links a mobile device (e.g., phone, computer) with a core network.
• RAN is divided into Real Time and Non Real time sections.
•  The data transfer architecture incorporates a variety of technologies.
•  Concepts like network slicing, mobile cloud engines (MCE) are used to expand RAN functions.

5G Core Network (5GC)

•  Manages 5G communication.
•  Connects various components within the overall architecture.
