Industry-leading Motorola Solutions recently conducted a global survey of Land Mobile Radio (LMR) system managers across 24 countries. A key finding of the research was that organizations that monitor their systems 24x7x365 have had nearly 50 percent fewer outages in the past year than those that do not.
Voltage Standing Wave Ratio (VSWR or SWR) is an important stat for transmitter sites that should be continuously measured and monitored to be able to see - and frequently preempt - a problem before it has a significant impact.
VSWR / SWR is worth paying attention to on a wireless transmitter site as it:
- Is a good measure of the overall health of the antenna system
- Can highlight degraded system performance – coverage, voice quality, data throughput, etc.
- Helps avoid damage and failure to transmitters and repeaters from high VSWR
- Indicates if the system is performing as designed and intended
