Wired vs Wireless - Direct Comparison
| Aspect | Wired (Ethernet) | Wireless (WiFi) |
|---|---|---|
| Connection Method | Physical cables (Cat5e/Cat6 Ethernet) | Radio waves (2.4 GHz / 5 GHz) |
| Speed | Very fast (1-10 Gbps typical) | Slower (50-1200 Mbps typical) |
| Latency | Very low (< 1ms) | Higher (5-20ms+) |
| Security | More secure (physical access required) | Less secure (can be intercepted wirelessly) |
| Reliability | Very reliable (no interference) | Can suffer interference (walls, devices) |
| Mobility | No mobility - tethered to cable | Full mobility within WiFi range |
| Convenience | Less convenient (need cable connection) | Very convenient (wireless connection) |
| Installation | More effort (run cables through building) | Easy (just place WAP/router) |
| Cost | Moderate (cables, switches) | Lower (just WAP/router) |
| Range | 100m per cable segment (then use switch) | 30-50m indoors (degrades with obstacles) |
| Device Suitability | Desktops, servers, stationary devices | Laptops, phones, tablets, mobile devices |
| Best For | Gaming, servers, security, streaming | Mobility, convenience, temporary access |
