What Is RF Interference?

RF interference occurs when unwanted RF signals transmit and interfere with cellular, wireless networks, or other communication-based systems. RF interference can result in a variety of problems that diminish the quality of a network and effect user experience like dropped calls or poor battery life. Troubleshooting and adjusting networks impacted by RF interference, then, is essential for signal integrity.

What Is Affected By RF Interference?

  • Cellular Data
  • Wireless Networks
  • Radio Signals
  • Occupational Safety Related Risks
  • Telecommunication Systems
