TransCore Proprietary 22
RF Interference or Poor Performance
Permanent structures and transient factors (such as large metal trucks) in the vicinity may aect RF signals.
Metal objects, walls, wet pavement, and ice can reflect RF signals, degrading system performance
(Figure 5).
Interference from RF and electrical sources can interfere with the optimal operation of the system.
Any RF interference at the site should be shielded, removed, or positioned farther from the Encompass 4
Reader if possible.
