Digi's unique XII™ Interference Immunity technology is a proprietary hardware and software feature set that allows product designers using Digi products to create wireless systems that are immune to most RF interferers (cell phones, pagers, other wireless systems, etc.).
When operating within the 900 MHz and 2.4 GHz frequency bands, cell phones, pagers and other wireless systems can dramatically interfere with wireless links.
Digi's XII™ technology can block 60 dB of interference. Interference just 1 MHz away can be 1 million times stronger than the Digi signal and only degrade the receiver sensitivity by 3 dB. This interfering device would have to output more than 100,000 Watts to significantly affect the transmission of Digi products.
Digi products utilize frequency hopping spread spectrum communication that, by design, delivers additional protection against interference.
