About XLR PRO® Radio Frequency (RF) Modem
The XLR PRO
RF Modem is a high performance, industrial grade long-range radio solution that offer serial, Ethernet
socket, and Ethernet bridging connectivity to ensure reliable wireless data communications over long distances.
There are two models:
•
XLR PRO RF Modem
for North American distribution
•
XLR PRO INTL RF Modem
for international distribution
In this guide, the term XLR PRO refers to both models.
Packaged in a sturdy, ruggedized enclosure and 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
•
Interference immunity
•
Improved multipath performance
•
Adjustable data rates
Flexible configuration and management options allow you to quickly set up and deploy one or more XLR PROs, as well
as apply firmware updates, get device status information, and more.
