Lection 1: GSM introduction

  • Basic GSM principles. Standards and protocols. APMS.

Lection 2-3: GSM architecture

  • Interfaces of interaction between various segments:
    • mobile stations (terminals);
    • base station subsystem;
    • network subsystem;
    • network management system.
  • Services, protocols, codes and hardware.

Lection 4: GSM physical and logical channels

  • FDMA – TDMA principles (providing multiple access).

Lection 5: Speech coding

  • Quantization, encoders’ standards, algorithms.

Lection 6: Channel coding

  • Redundancy checks and noise reduction. Principles and algorithms.

Lection 7: Physical and Logical channels

  • Bursts and frames. Classification, features, definition.
  • Logical channels:
    • broadcast control;
    • common control;
    • dedicated control;
    • traffic.

Lection 8: Messages

  • Studying interfaces layers.

Lection 9-10: Call management

  • Principles, algorithms, components interaction.

Lection 11: GPRS

  • Classes, network model, external connections, address allocation.

Lection 12: GSM security

  • 3 security problems: unauthorized access, privacy and identity (location) protection.
  • Authentication algorithms.

Lection 13: Signal propagation and cellular technology

  • Fading (frequency dependent), shadowing, reflection at large obstacles, refraction depending on the density of a medium scattering at small obstacles, diffraction at edges.
  • Macro-, micro- and picocells.
  • In-building coverage, handling slow and fast moving subscribers.
