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:

nGreater receiver sensitivity

nInterference immunity

nImproved multipath performance

nAdjustable data rates

The XLR PRO RF Module flexible configuration and management options allow you to quickly set up

and deploy one or more XLR PRO RF Modules, as well as apply firmware updates, get device status

information, and more.
