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:
“To many women marriage is only this. It is merely a physical change impinging on their ordinary nature, leaving their mentality untouched, their self-possession intact. They are not burnt by even the red fire of physical passion—far less by the white fire of love.”
—Mary Webb (1881–1927)
