General information about the XBee/XBee-PRO

DigiMesh 2.4 RF Module

The XBee®and XBee-PRO®DigiMesh 2.4 RF Modules are engineered to support the unique needs of

low-cost, low-power wireless sensor networks. The modules require minimal power and provide

reliable delivery of data between remote devices. The modules operate within the ISM 2.4 MHz

frequency band.

Easily build networks up to 32 nodes using the XBee modules. For larger networks up to 1000+

nodes, Digi offers RF Optimization Services to assist with proper network configuration. Contact Digi

Technical Support for more details.
