The TIA-329.* series standards deal with antenna systems.
\nTIA-329.1-* deals with requirements for and measurements of Base
\nStation antennas. TIA-329.2-* deals with measurements of mobile
\nantennas. This standard, TIA-329.3, deals with measurements of
\nportable antennas.<\/p>\n
The term "portable antennas" in this context is taken to mean
\nany antenna mounted on or built-in to a portable communication
\ndevice. It also includes any human-worn antenna intended to be used
\nexclusively with a portable communication device.<\/p>\n
The term "portable communications device" includes, but is not
\nlimited to, the following classes of devices:<\/p>\n
\u2022 Hand-held portable transceivers (i.e. "walkie-talkies")<\/p>\n
\u2022 Packset portable transceivers<\/p>\n
\u2022 Paging receivers<\/p>\n
\u2022 Hand-held mobile (cellular) telephones<\/p>\n
\u2022 Portable information devices<\/p>\n
\u2022 Devices intended to be plugged-in to a laptop computer via an
\nAccessory Port or a USB port<\/p>\n
It is the intent of this document to present a method of
\nmeasuring in situ<\/i> portable antenna performance for
\napplication to network design. There are a number of factors that
\naffect antenna operation on a portable device that are part of the
\nambient environment within a few wavelengths of the portable
\nantenna. These factors from the ambient environment are detached
\nfrom the portable transceiver and the portable antenna themselves.
\nThe factors include the dielectric and absorption properties of the
\nbodies of the personnel holding the portable device with their
\napparel, together with aspects of the posture, azimuth, and
\norientation of the antenna, and any furnishings, vehicles, or
\nenvironmental edifices within a few wavelengths of the antenna.
\nOther details of the ambient environment can also introduce
\nfactors, such as a factor for precipitation or moisture. A
\nmeasurement of portable antenna operation requires the selection of
\nsome sample of the portable devices, and any associated factors,
\ncombined with the technical means to make the measurement for all
\nthe selected samples. This selection of factors constitutes the
\ntest condition(s) of an experiment. If the selection of the factors
\nin the test condition is successful, then the measurement results
\nwill be distributed to permit statistically valid conclusions about
\nportable device(s) operation in a network design. The method of
\nmeasurement includes an experimental design for the purposes of
\nmeasuring portable antenna operation for receiving or transmitting
\nmessages with the selection of some set of test conditions that is
\nwithin the technical means of effort to apply the measurement. The
\nmeasurements results will then be a set of data points that are
\nstatistically analyzed to draw valid conclusions, if there are any.
\nSince the factors from the ambient environment are likely to change
\nfor different applications or purposes, the repeatability of the
\nmeasurement results may not be always possible, unless the
\nexperiment is designed to tightly constrain the factors that affect
\nportable antenna operation. Any extension of experimental test
\nresults to other portable devices, or other antennas, or to
\ndifferent ambient factors is not anticipated by this standard..<\/p>\n
