Radio communication network using Omnet++ Projects.
Radio communication is a system of telecommunication utilizing electromagnetic waves of a particular frequency range to transmit speech or other sound over long distances without wires.
Features of radio communication network:
- Radio network capacity management.
- Coverage.
- Conversation privacy.
- Network manageability.
- Location services.
- Spectral efficiency.
- Long Distance coverage.
Applications of radio communication network:
- For Early warning disaster relief operations.
- Energy saving in green radio networks.
- Marine service.
- Used in aeronautical applications.
- Security.
Research on radio communication network:
- Communication planning and coordination.
- Achieving reliability.
- Reduce interference issues.
- Monitoring firefighter welfare and location on-scene.
- Terrain.
