About the XLR PRO RF Module

The XLR PRO RF Module is a high performance, industrial grade, long-range radio solution that
ensures reliable wireless data communications over long distances.
Using patent-pending Punch2™ Technology to maximize range and significantly increase immunity to
interference, the XLR PRO 900 MHz radio can connect a variety of devices across many industrial
applications.
Punch2 Technology leverages chirp spread spectrum (CSS) modulation to provide better receiver
sensitivity, multipath performance, and interference rejection than is available through commonly
used frequency hopping spread spectrum (FHSS) or direct sequence spread spectrum (DSSS) systems.
The advantages of Punch2 Technology arise from the characteristics of the chirp signal as well as
several digital-signal-processing techniques that enhance performance and reliability. With Punch2
Technology, data is spread to a higher bandwidth by multiplying each transmit modulation symbol
with a chirp signal. Operating at an expanded bandwidth provides several benefits:
Greater receiver sensitivity
