The new demo, which follows a September 2022 demonstration of outdoor communications, looks to advance ZETag adoption for a wide range of products in the IoT consumer and industrial markets.
The demonstration experiment was able to verify the performance in an asset management use case involving indoor operation, an environment where communication is more challenging than outdoor.
The demonstration experiment confirmed that, by taking advantage of Advanced M-FSK modulation to improve sensitivity in indoor spaces where wireless communication can be difficult, it is possible to use a single access point installed at an appropriate location to automatically verify the presence of a large number of items spread across two floors, each with approximately 3,700m2 of floorspace.
The demonstration experiment also confirmed that data collected from the temperature sensor in the Toppan tags that were used, could be used for purposes other than asset management, such as monitoring the temperature in the office.
The demonstration tags were attached to objects (assets under management) in Socionext’s Kyoto office and their continuous presence within the area of interest was verified over a period of about two months using a well-positioned antenna that received regular data transmissions from the tags.
The results, according to Socionext, proved the practicality of asset management automation using tags integrated with the SC1330A Advanced M-FSK LSI equipped with just a single access point capable of supporting communications with 50 tags spread across two floors.
Techsor has also developed a visualization platform using Microsoft Power BI that provides details of asset inventory and temperature changes in indoor environments.
The September 2022 effort involved members of the ZETA Alliance jointly conducting an outdoor communication testing of an Advanced M-FSK-compatible tag evaluation system that demonstrated greater reliable communications than conventional tags. The experiment used the first ZETag with SC1330A-equipped from a trial production by Toppan, a member of the ZETA Alliance.
The ZETag using the SC1330A LSI is able to support Advanced M-FSK modulation.
Commercial production commenced in March 2023.
