There are several types of mutual interference among frequency-sharing systems: (1) interference among terrestrial stations; (2) interference between satellite–earth links; and (3) interference between terrestrial stations and earth stations.
The reradiated signals are usually very low in amplitude. However, if the radiating element (rusty fence, barn, or downpipe) is close to the receiver of a base station and if its intermodulation product falls within the receive band, the result will be receiver desensitization. Figure 7. Beyond the antenna, or rusty bolt PIM.
As for interference among terrestrial stations (noncellular, non-PCs, and nonsatellite), in the lower part of the frequency spectrum (<200 MHz), most of the terrestrial services do not suffer from interference problems. Mutual interference that could exist has been limited to acceptable levels by good frequency planning.
Because different linear polarizations reflect and penetrate surfaces difkently. the most cost-effective way to reach inside structures is through the use of circularly polarized base-station antennas.
Circulators, duplexers, and switches are particularly prone to the effect. Designers may choose to accept higher levels of passive intermodulation by selecting lower cost, smaller size, or lower performance options. Figure 2. Component design trade-offs, size, power, rejection, and PIM performance.
