The invention provides a positioning system of positioning a wireless
communication apparatus. The positioning system transmits and receives
positioning signals which have different frequency bands and generates
corresponding positioning values according to the positioning signals.
The positioning system then judges and selects positioning values which
have less error from the generated positioning values, and calculates an
average value of the selected positioning values. Therefore, positioning
of the wireless communication apparatus will be more precise.
Furthermore, if the positioning system is implemented in a
radio-wave-based wireless communication environment, the N positioning
signals can be polarized in a linear polarization way, a left-handed
circular polarization way or a right-handed circular polarization way, so
as to reduce the environmental impact to enhance precision of the
positioning.
