Thank you for reviewing my question. I am researching "Wi-Fi__33". It's a real thing. I see it mentioned in places such as http://www.logisticsit.com/blog/2017/02/07/three-retail-tech-trends-to-watch-in/, and http://www.omega.com/technical-learning/next-industrial-revolution.html, but I find no definition of it anywhere. I think it may be used in payments, retail, and/or Industry 4.0. It could be quite new. I could really use a definition.
I really think this is a copy paste error (trademark symbol unicode error?).
Look at this http://www.mouser.com/catalog/specsheets/panasonic_PAN9310_9320%20Series.pdf One component is clearly indicated as a Wifi__33 whereas another reference of the same product is normal "Wifi"
but the Official datasheet indicate that only the antenna differ.
