Frequency

XBee modules are available in a wide variety of RF frequencies used around the world. XBee frequency affects range, and it also affects the location where you can deploy your application due to regulation differences between countries. Modules with different frequencies cannot be mixed on the same network. Developers can support frequencies including:

• 2.4 GHz
• 902 - 928 MHz
• 865 - 868 MHz

To determine the frequency that is best for your application, you need to answer two questions:

1. Where is your application going to be deployed?

   Since some frequencies are not allowed for unlicensed use in certain countries, it is important to consider the location of your application when you select the frequency of your XBees.

   Note XBee devices have been certified for use in certain countries. See the specific product manual for the latest details.

   • 900 MHz radio frequency band is for unlicensed use only in North America and Australia.
   • 868 MHz radio frequency band is for unlicensed use only in Europe.
   • 865 MHz radio frequency band is for unlicensed use only in India.
   • 2.4 GHz is an unlicensed radio frequency band used worldwide.
2. What is the maximum range your application needs to communicate?

   900 MHz, 868 MHz, and 865 MHz XBee modules offer much greater range than 2.4 GHz XBee modules.
