Abstract: A building system including one or more memory devices configured to store instructions that, when executed on one or more processors, cause the one or more processors to collect building device data of a building device, generate a time correlated data stream for a data point, and generate a time correlated reliability data stream for the data point. The building device data includes a plurality of data samples of the data point. The time correlated data stream includes values of the plurality of data samples of the data point. The time correlated reliability data stream includes a plurality of reliability values time correlated to corresponding values of the plurality of data samples of the data point and indicating reliability of the values of the plurality of data samples of the data point.

Abstract: A portal stand for an RFID antenna comprises a pair of upright members and a front cover. The front cover is formed of a sheet of plastic that is resiliently biased to assume a flat configuration, with the front cover defining a flat width when it is in the flat configuration. The upright members include vertical slots and are spaced apart at a distance that is less than the flat width of the front cover. The front cover is disposed in the vertical slots and is bowed outwardly. The portal stand also includes a plurality of platforms that may be used for mounting RFID equipment such as antennas and readers. The platforms are secured to rails that are also secured to the upright members. The portal stand also includes a top cover, bottom cover, and rear cover, with the platforms being positioned between the front cover and rear cover.
