A method and apparatus for wireless transmission of data through a communications
channel between at least two local data sensors (for example automotive diagnostic
data sensors or NVH sensors), which may include a primary data-processing function,
and data-processing function (for example a PC) to receive data therefrom. The
system provides for asymmetrical division of the communications channel on a frequency
or time-division or packet-switching basis so that the corresponding asymmetrical
data transmission requirement of the local data sensors are matched to the capacity
of their respective sub-channels whereby a single channel is capable of transmitting
all the required data. A particularly practical application is to noise vibration
harshness analysis of wireless-transmitted data from three-dimensionally spaced
NVH sensors enabling special pinpointing of vibration sources in automotive warranty
analysis studies.
