Gateways

The RF frequency range differs between Europe and America due to different regulatory requirements:

• Europe:
  In Europe, frequency bands such as the 868 MHz band and the 2.4 GHz band are approved for industrial, scientific and medical (ISM) applications. The 868 MHz band offers greater range with low power consumption, but is limited in bandwidth.
• America:
  In the USA, the 915 MHz band and the 2.4 GHz band are predominantly used. The 915 MHz band allows a higher bandwidth than the European 868 MHz band, but at the expense of a slightly shorter range.

The globally available 2.4 GHz band is suitable for applications that require global connectivity, such as Wi-Fi and Bluetooth. Companies must ensure that their devices meet the relevant frequency requirements and regulatory standards of the respective region.

Digi XBee wireless modules are available in three different form factors, which vary depending on the application and installation requirements:

• Through-Hole (24.38mm x 27.61mm):
  This form factor is the standard for all Digi XBee variants and offers easy installation on PCBs. It is ideal for prototypes and low-volume applications.
• Surface mount (21.99mm x 34mm):
  The SMT variant is specially designed to meet the requirements of high-volume manufacturing. It enables space-saving assembly and offers automated assembly in series production.
• Micro (13mm x 19mm):
  The Micro version is particularly compact and optimized for portable and space-critical applications. It is suitable for wearables, sensors and other devices where size is critical.

This variety of form factors ensures flexibility for a wide range of development and production requirements.
