🔗 Bluetooth: The People’s Choice for Short-Range, Device-to-Device Communication
- 🚶 Short Range — Typically within 10~30 meters.
- 🚀 Medium to High Data Rate — Suitable for audio streaming and real-time interactions.
- 💡 Very Low Power (BLE) — Bluetooth Low Energy ensures long battery life.
- 📲 Seamless Smartphone Integration — Widespread adoption in wearables and mobile access controls.
- ⚠ Limited Networking Capabilities — Mainly point-to-point or simple star topologies, with limited expansion [5].
Commonly used for wearable devices, smart locks, health monitoring devices, and proximity-based IoT systems.
📷 WiFi: High-Speed Data-Intensive Communication
- 🖥 Medium Range — 10~50 meters, with signal easily blocked by walls [5].
- ⚡ High Data Rate — Perfect for video streaming, cloud data upload, and high throughput applications.
- 🔌 High Power Consumption — High power draw constrains battery use [4].
- 🛠 Indoor Signal Blockage — Signal quality may degrade in multi-wall or RF-dense environments.
- 🌐 Home and Office Focused — Designed for centralized router-based communication.
Used extensively in smart offices, home devices, and streaming services — but not ideal for battery-centric or long-range use.
