Recommendations for Highly Reliable Radio Link:
• Maintain the use of Forward Error Correction (FEC) in challenging radio
environments such as urban areas. FEC is the default option in the ‘R2CR
Radio Data Receiver’ rmware.
• Use of Received Signal Strength Indication (RSSI) to measure the radio
environment before using GNSS receivers in a job site. RSSI value is
available to our end users through our GNSS eld application software,
which is an integral part of all GNSS systems. For more sensitive job sites
like airport construction, our customers and professional service team are
trained to use a spectrum analyzer and other typical radio tools to ensure
the environment is free from radio signal jamming or interference.
• Cooperation with the local radio-governing authorities to determine the
optimum free radio channel.
• Avoid using channels nearby local TETRA or television frequencies, which
generally are not recommended for use in this application.
• Use a repeater in an intermediate position, to extend the length of the link
and/or increase the receive signal level at the rover.
