Fuzzy Locating System - Physical Restrictions

Physical Restrictions

Measurement of propagation parameters is generally heavily loaded with various noise components. Such noise may be stochastic or deterministic or a mixture of noises with limited bandwidth .

As with all wireless systems, qualities of measurement in any one aspect contradict to qualities in some other aspects:

  • Especially extension of reach collides with reducing the separation limits.
  • Also increase of probing duration collides with motion speed.
  • Generally the requirement for unambiguous locating requires a set of measured distances.

Such contracdictions result in challenges for systems performance and in hard restrictions concerning timely parallel availability of certain quality levels. Facing limitations as inevitable, the implementer of a locating systems has to determine the operational requirements first and then has to make a choice under a set of alternatives and must scale the adjoint limitations. The outcome is always a compromise with trade offs usually in budgetary effort and in technical precision. Any chosen alternative generally will exclude certain other technical options from operational availability.

Famous quotes containing the word physical:

    The entire construct of the “medical model” of “mental illness”Mwhat is it but an analogy? Between physical medicine and psychiatry: the mind is said to be subject to disease in the same manner as the body. But whereas in physical medicine there are verifiable physiological proofs—in damaged or affected tissue, bacteria, inflammation, cellular irregularity—in mental illness alleged socially unacceptable behavior is taken as a symptom, even as proof, of pathology.
    Kate Millett (b. 1934)
