Readers which support Tag Locationing feature report the same in the field isTagLocationingSupported of ReaderCapabilities as true. This feature is supported only on Handheld readers and is useful to locate a specific tag in the field of view of the readers antenna. The default locationing algorithm supported on the reader can perform locationing only on a single antenna. reader.Actions.TagLocationing.Perform can be used to start locating a tag, and reader.Actions.TagLocationing.Stop to stop the locationing operation. Result of locationing of a tag is reported as LocationInfo in TagData and will be present in TagData if tagData isContainsLocationInfo is true. tagData.LocationInfo.getRelativeDistance gives the relative distance of the Tag from the Reader Antenna.
