Sources of Interference
Radios are designed to detect specific radio frequencies. “Noise” is defined as an
unwanted signal which has been transmitted at the same frequency as the radio was
designed to detect. There are many man-made and natural sources of “noise”.
(lightning, power lines, switching power supplies, fluorescent lighting, microwave ovens,
...)
Due to the spread spectrum and frequency hopping techniques, the OS2400 operates
more efficiently than a radio which operates using conventional technology.
?? Networks installed in rural areas will encounter less man-made noise than in
suburban or urban areas.
?? If possible, use a directional (high gain) antenna at the Remote locations.
?? Verify that each network operating in close proximity to each other has BEEN
ASSIGNED TO A DIFFERENT CHANNEL.
?? A network’s output power can be changed:
?? raise the power to “drown out” the competing noise
?? lower a network’s output power if it is interfering with another network in the vicinity
