UFH communication module

UFH communication module

Function:

RFM869 is actually a UHF delivery-accepting module, operating on 433, 868 and 915 MHz free from licensing ISM (Industry Scientific and Medical) frequency ranges. All its basic RF communication parameters are programmable and most of them can be dynamically altered. The module provides opportunity for choice of communication channels with various frequency band widths without being necessary to change the components or their parameters. The optimization is for low power communications and at the same time it provides high RF power and channel formation in compliance with the European (ETSI EN 300220) and the North American (FCC part 15) standards. Suitable for frequency hopping applications at point-to-point-to-multipoint network layouts.
