Performance specifications
Note
Range figure estimates are based on free-air terrain with limited sources of interference. Actual range will vary
based on transmitting power, orientation of transmitter and receiver, height of transmitting antenna, height
of receiving antenna, weather conditions, interference sources in the area, and terrain between receiver and
transmitter, including indoor and outdoor structures such as walls, trees, buildings, hills, and mountains.
This document describes how Digi RF products are designed to have good out-of-band interference rejection from
other sources of RF emissions 1 MHz or more away from the frequency in which the Digi RF product is designed to
operate. An out-of-band interfering radio is one that is intended to broadcast in one frequency but has RF energy that
bleeds-over to affect a second radio operating on a different frequency. Final performance can still vary at any
particular installation site, dependent on both the physical environment in which the radio is installed and the
amount of in-band and out-of-band interference sources broadcasting in that same localized area.
