Overview
Understand 2.4 GHz and 5 GHz WiFi channels, overlap, interference and antenna planning.
Practical reference
- Check the correct frequency band before choosing an antenna.
- Use antennas, connectors and cables rated for the operating frequency.
- Verify regional RF regulations before shipping a product.
- Test the final enclosure and installation position.
Engineering notes
RF performance depends on frequency, antenna size, cable loss, connector quality, ground plane, enclosure design and installation environment.
