Freedom of Perception: How WSN Instantly Captures the Physical World
What is Wireless Sensor Network (WSN)?
WSN is the bridge between the physical and digital world. It captures real-world data using small, low-power sensor nodes and transmits it wirelessly for smart monitoring and control.
How It Works

Communication Protocols
Wireless data transfer is prone to interference, requiring robust communication protocols:
| Protocol | Frequency | Range | Speed | Security | Network Type |
|---|---|---|---|---|---|
 |
2.4GHz | 10–100m | 250 Kbps | AES-128 | Mesh |
 |
2.4GHz | 10m | 3 Mbps | AES-128 | Star/Mesh |
 |
2.4/5GHz | 100m | 54 Mbps | WPA2 | Star |
 |
868/915MHz | 10–30m | 250 Kbps | AES-128 | Star/Tree/Mesh |
