Wi-Fi Access Point Placement for 2.4 GHz and 5 GHz[edit]
This page provides guidelines for placing Wi-Fi access points (APs) to optimize coverage and performance for both 2.4 GHz and 5 GHz bands.
Overview[edit]
Wi-Fi networks commonly operate on two frequency bands: 2.4 GHz and 5 GHz. Each band has different characteristics:
| Feature | 2.4 GHz | 5 GHz |
|---|---|---|
| Range | Long, penetrates walls better | Short, limited range |
| Speed | Slower, more crowded | Faster, less interference |
| Interference | Common (Wi-Fi, Bluetooth, microwaves) | Less crowded |
| Best Use | General coverage | High-speed connections nearby |
---
General Placement Guidelines[edit]
- Place APs in a **central location** within the coverage area.
- Mount APs **high on walls or ceilings** for better signal distribution.
- Avoid obstacles such as **metal, mirrors, thick walls, and microwaves**.
- Consider **band steering** or separate coverage planning for 2.4 GHz and 5 GHz.

Band-Specific Guidelines[edit]
2.4 GHz[edit]
- Longer range; fewer APs needed.
- 10–15% coverage overlap is sufficient for roaming.
- Works well through walls and floors.
- Suitable for broad coverage areas.
5 GHz[edit]
- Shorter range; APs should be closer to users.
- Direct line-of-sight provides best performance.
- 20–30% overlap recommended for seamless roaming.
- Ideal for high-density areas requiring fast connections.

Channel Planning[edit]
- 2.4 GHz: Use channels **1, 6, or 11** (non-overlapping).
- 5 GHz: Use available channels avoiding DFS if devices do not support them.
- Proper channel planning reduces interference and improves performance.
---
Practical Layout Tips[edit]
- **Small home**: One centrally located AP can cover both bands.
- **Medium home / small office**: Place one AP per floor; 2.4 GHz covers distant rooms, 5 GHz covers nearby rooms.
- **Large office / multi-floor building**: Conduct a site survey; place 5 GHz APs ~25–30 feet apart, 2.4 GHz APs further apart.
