What is the LTE protocol stack?

The LTE protocol stack is a set of layered protocols used in Long Term Evolution (LTE) mobile networks to manage communication between mobile devices and the network. It includes layers such as the Physical Layer (PHY), Medium Access Control (MAC), Radio Link Control (RLC), Packet Data Convergence Protocol (PDCP), and Radio Resource Control (RRC). Each layer serves a specific function, such as data transmission, error correction, and managing signaling. Understanding the LTE protocol stack is essential for developing, testing, and troubleshooting mobile network solutions.
