Antenna reports

The concepts of item presence and and antenna presences have been introduced here.

Next to antenna presences there's the notion of antenna reports, describing the quality and proximity details of a tag per antenna in much more detail.

This is especially useful in case the density of Smartspot antennas is so high that their detection zones overlap substantially. In this case the location engine of the Brain may need additional information to base a decision upon. For this reason, Smartspots can generate so called antenna reports.

With antenna reports setting enabled, Smartspots will generate statistical reports based on the received signal strength information of an individual tag over a particular time frame. The time frame used is determined by the antenna report interval, indicating the time between each antenna report, expressed in tenths of seconds (so called deciseconds).

So, for example, during a period of 4 seconds a Smartspot collects all raw signals reads received from a tag over that period, analyzes these signals and converts the data to a statistical report describing the received signals over time. This grearly reduces the amount of data that is transmitted to the Brain.

How Brain uses antenna reports

If a tag is in the range of multiple Smartspots or multiple Smartspot antennas, these statistical antenna reports are generated for each and every Smartspot antenna, independent from whether the antenna is an internal Smartspot antenna or external.

So, for the given tag, the Brain will periodically receive the antenna reports from all Smartspots and all Smartspot antennas that have the tag in range.

The Brain localization engine will process the combined information and will update the estimated location every time a new report has been received (determined by the antenna report interval).
