(a) Applications of Wireless Communication in Vehicles and Emergency Situations
1. In Vehicles:
-
Vehicle-to-Vehicle (V2V) Communication: Helps prevent collisions through real-time data exchange.
-
Vehicle-to-Infrastructure (V2I) Communication: Supports smart traffic management and toll collection.
-
GPS & Navigation Systems: Provides real-time location tracking and route optimization.
-
In-Car Wi-Fi & Infotainment: Enables internet access, music streaming, and video calling.
-
Autonomous Driving Support: Assists self-driving cars through LiDAR, radar, and wireless sensors.
2. In Emergency Situations:
-
Emergency Alert Systems (EAS): Sends mass alerts for disasters like earthquakes and floods.
-
Search and Rescue Operations: Uses satellite and drone communication for locating victims.
-
First Responder Communication: Ensures uninterrupted contact between emergency personnel.
-
Medical Telemetry & Telemedicine: Enables remote patient monitoring and emergency medical guidance.
-
Disaster Recovery Networks: Deploys mobile networks in disaster-hit areas for relief operations.
(b) Comparison of Wired and Wireless Networks
Characteristic | Wired Network | Wireless Network |
---|---|---|
1. Reliability | More reliable, less interference | Prone to interference and signal loss |
2. Speed & Bandwidth | Higher speeds and stable bandwidth | Lower speeds, affected by congestion |
3. Mobility | Limited to fixed locations | Provides high mobility and flexibility |
4. Security | More secure, harder to intercept | More vulnerable to hacking and eavesdropping |
5. Installation & Cost | Expensive setup with cables and infrastructure | Cheaper and easier to deploy |
Both network types serve different purposes, with wired networks preferred for stability and security, while wireless networks excel in flexibility and mobility.
