2.4GHz vs 5GHz: Which Band for Smart Devices?
📡 2.4 GHz
- ✅ Longer range (150+ feet)
- ✅ Better wall penetration
- ✅ Supported by ALL smart devices
- ❌ Slower speeds
- ❌ More interference
- Use for: bulbs, sensors, plugs, cameras
⚡ 5 GHz
- ✅ Much faster speeds
- ✅ Less interference
- ❌ Shorter range (50-80 feet)
- ❌ Many smart devices don't support it
- ❌ Poor wall penetration
- Use for: TVs, game consoles, laptops
💡 Pro Tip: Separate Your Networks
Name your 2.4GHz and 5GHz networks differently (e.g., "HomeNet" and "HomeNet_Fast"). This prevents smart devices from accidentally connecting to the 5GHz band they can't use.

Router Placement for Smart Homes
- Center of your home: Place the router as centrally as possible to minimize maximum distance to any device.
- Elevated position: WiFi signals spread downward. A router on a shelf covers more area than one on the floor.
- Away from microwaves and cordless phones: Both operate on 2.4GHz and cause interference with smart devices.
- Not in a cabinet or closet: Metal and walls dramatically reduce signal strength.
- Use mesh for large homes: If your home is over 2,000 sq ft, one router rarely provides reliable coverage. Mesh systems like Eero, Orbi, or Google Nest WiFi solve this.
