Signal Interference
Signal interference is RF signals that interfere with the information being
exchanged between the tag and the scanner. Signal interference can
severely diminish the scanner’s ability to read information from the tags.
The Activity LED on the scanner flickers constantly if it detects signal
interference.
The source of the interfering signals may be:
• An RF system, such as an RF local-area network (LAN) or another
Interactive Identification system, located close to your system.
• Security gates, garage doors, or similar devices that emit RF signals.
• Appliances such as microwave ovens.
The effects of these noise sources are localized and can be eliminated by
relocating the scanner and its antenna.
Your system’s communication capabilities are significantly reduced when
the noise level perceived by the system exceeds the strength of signals
received.
