model does not determine the actual probability of interference.
While the extremely small amount of reported interference
by ISM equipment makes experimental
verification of the model difficult, its results are compatible
with the low incidence of interference reported.
SESSION 4C
D. I. Weinberg, T. L. Wilson: Model of TV Interference from ISM Equipment
The model shows that emission limits can be raised by at
least 23 dB(fjWm) just to compensate for the various
probabilities of operation in the television band. Additional
increases can be used to compensate for local
shielding and other factors. The setting of realistic limits
can result in the saving of millions of dollars annually in
the cost of ISM equipment, which will be reflected in the
cost of products manufactured using ISM equipment.
With some changes in the model, it can also be used to
evaluate the effects of changes in ISM operations on the
probability of interference with other communication and
navigation services.

This model was developed as part of the authors' activities
on the Advisory Committee to the United States Delegation
to the International Radio Consultative Committee (CCIR).
Among the committee members whose comments contributed
to its development are Ernest Freeman, Hua-Feng
Huang, Julius Knapp and Robert Pratt.
