🔶 5G PROTOCOL STACK 🔶

🔶 5G PROTOCOL STACK 🔶

🌊Physical Layer (PHY) 🌊

Function: Converts digital bits into signals (electromagnetic waves) for transmission.

Example: Like turning text messages into radio waves that travel to a cell tower.

Key Technologies: OFDM (Orthogonal Frequency-Division Multiplexing), MIMO (Multiple Input Multiple Output).

🎛️MAC Layer (Medium Access Control) 🎛️

Function: Manages data transfer between the physical layer and the higher layers.

Example: Allocating different users different time slots, like managing who speaks when in a group conversation.

Key Technologies: Dynamic TDD (Time Division Duplex), Carrier Aggregation.

🌐RLC Layer (Radio Link Control) 🌐

Function: Ensures reliable data transfer, managing error correction and retransmissions.

Example: Like a delivery service that ensures a parcel (data) reaches its destination correctly, and resends if it doesn’t.

Key Technologies: ARQ (Automatic Repeat reQuest), Segmentation and Reassembly.

🛡️PDCP Layer (Packet Data Convergence Protocol) 🛡️

Function: Compresses and encrypts data; also responsible for header compression.

Example: Like packaging data securely and efficiently for transport, akin to vacuum-sealing a product for shipping.

Key Technologies: Header Compression, Security (Encryption and Integrity Protection).

🎮RRC Layer (Radio Resource Control) 🎮

Function: Controls the lower layers and manages the resources of the radio interface.

Example: Like a traffic controller, managing how data flows across the network and allocating resources.

Key Technologies: Mobility Management, Connection Setup and Release.

S🧩DAP Layer (Service Data Adaptation Protocol) 🧩

Function: Newly introduced in 5G, this layer maps data flows to the correct Quality of Service (QoS) flows.

Example: Assigning different priority levels to data, like giving ambulances a fast lane in traffic.

Key Technologies: QoS Flow Mapping.

📡Non-Access Stratum (NAS) 📡

Function: Manages the signaling between the user equipment and the core network.

Example: Like the communication between a smartphone and the network provider for services like SMS or voice calls.

Key Technologies: Authentication, Session Management.

Each layer in the 5G protocol stack has a specific role, ensuring efficient, secure, and reliable communication in the network. The stack is designed to handle the high data rates and low latency requirements of modern applications, from streaming high-definition videos to supporting autonomous vehicles and smart city infrastructures.
