GSM Radio Stack

The GSM Radio Stack comprises multiple layers, each responsible for different communication aspects in GSM mobile networks:

1. Physical Layer (Layer 1): Manages the actual radio transmission and reception.

2. Data Link Layer (Layer 2): Includes protocols like LAPDm, responsible for error correction and reliable data transfer.

3. Network Layer (Layer 3): Consists of sub-layers for call control, mobility management, and radio resource management.

This layered approach ensures efficient management and operation of GSM mobile communications.
