As wireless technology becomes commonplace, there are many mission-critical applications that are heavily dependent on reliable data networks.

To overcome these obstacles, companies often turn to unlicensed 900 MHz wireless solutions to connect devices over longer distances. However, these sometimes-harsh environments can present conditions that decrease reliability and hinder performance of wireless signals. For example, many oil and gas fields today are saturated with RF noise, which often leads to interference and data loss. The Digi XLR PRO with Punch2 Technology was created to solve this issue and provide businesses with reliable wireless communications.

Punch2 Technology leverages chirp spread spectrum (CSS) modulation to provide better receive 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.

Punch2 Technology enables the Digi XLR PRO radio to achieve unparalleled range of 100-plus miles, industry-leading receive sensitivity and interference immunity, and reliability in noisy RF environments.
