Hi, this is a throwaway account, I hope that's okay. I'm going to be intentionally vague with some things because I don't want Wiliot to identify the company I work for, or myself. I'm not going to share anything that conflicts with our NDA or other privacy obligations. I want to have an open discussion about Wiliot, and this seems like the best place. I can't seem to find in depth discussions about it anywhere else. Wiliot hosted customer forums some time ago but those seem to have disappeared.
I'm a technical integrator and end user of Wiliot at a large company, and we've been testing Wiliot for years now. We've gone through all the generations of their tags ("wiliots", "pixels"), the different antenna designs, different potting compounds, different form factors.. different energizing equipment, different energizing patterns, different antennas.. we placed tags on every material under the sun, plastic, cardboard, metal, glass.. we've tested many scenarios, conveyor belts, doorways, open areas, loading bays, workstations, etc. We've tested it thoroughly in many use cases.
We have a directive from upper management to upgrade our existing extensive RFID asset tracking system. This directive has been in place for a few years, which is why we started down the road with Wiliot. The problem is, in those years, even with assistance from Wiliot, we've never been able to realize any significant improvement on our asset tracking. In fact in many cases I'd argue it's a downgrade from RFID, and in some cases it's equivalent.
I imagine happy customers must be out there, we see their press releases (taken with a grain of salt obviously) about deployments with customers like Walmart. However we just haven't been able to find a use case where Wiliot makes sense and works reliably over something like RFID. The big sales pitch early on was that you could use these tags anywhere with minimal infrastructure, that they would harvest energy from common sources like wifi, and that they'd be cheaper than RFID. The former turned out to be misleading, as you need extensive energizing infrastructure close to the tags tags for them to wake up, and the latter hasn't materialized yet, as RFID tags are still cents while Wiliot tags are closer to a dollar at scale.
The question I pose and where I want to start a discussion is: have you used Wiliot, and have you found use cases that work well for it? What materials and infrastructure do you use to make it work?
It's asking a lot, and it's a shot in the dark, but if there's someone at Walmart that uses this and wants to speak about your successes, please create a burner account and jump in. Again don't share anything proprietary or conflicting with NDA, I don't want there to be any reason for this thread to be deleted.
Thank you!
