The Wiliot Vision
What happens when everything has intelligence?
Wiliot envisions a world of smarter "Things" that are self-aware and offer functionality not possible before — a world where the physical and digital worlds are securely connected using wireless RF technology. The Internet of Things can scale and start to offer real value as we understand where products are, who is using them, and when they need replenishing. Apparel and pharmaceutical packaging can become connected to the cloud. Manufacturing, supply chain, and inventory can be optimized. Makers of products and retailers can flourish in the face of disruption from online retailers.
A change that Wiliot is helping to accelerate is being described as a shift from supply chain to demand chain management. Demand chains are enabled by demand signals flowing in real-time from products in stores and homes, reducing the capital tied up in inventory, driving lift in sales, enhancing the customer experience, and reducing companies’ carbon footprint. The way products are made, distributed, sold, used and recycled, are being redefined thanks to insights from an IoT Sticker.
Seamless Continuous Connectivity + Low Cost of Production
Wiliot was conceived with the idea of scaling the internet of things to billions. Instead of making more IoT devices, Wiliot brings intelligence and connectivity to products and packaging. The pre-existing infrastructure of Bluetooth is an invaluable communication network to tap into - Bluetooth radios are built into our smartphones, smart speakers, access points, and even in the many lighting infrastructures. Beyond the radios, Bluetooth has deep hooks into the operating systems we use every day. This connectivity is seamless and doesn't require the user to take action. For this technology to be realistically integrated into products, Wiliot had to also think about the form factor. Wiliot IoT stickers are hyper-thin and can be embedded. By reducing what was once on a printed circuit board to a single chip, and eliminating the need for a battery, Wiliot IoT Stickers can be manufactured by industry-established, high-speed processes to enable the lowest cost production. This, in turn, results in an affordable, high-quality tag. Wiliot technology includes sensing, ubiquitous connectivity. Data is protected, analyzed, and curated by the Wiliot Cloud, and made available through a RESTful API providing an interface for applications.
The chip consists of 5 main components: an energy harvester that captures ambient RF energy, an integrated sensing unit, a security unit, a processing unit, and a Bluetooth transmitter. It has three CPU cores, an ARM processor, has ROM, RAM, SDRAM, inputs, and outputs - it's a computer.

- Supply chain (presence, change of location, inventory)
Wiliot IoT Stickers obtain energy by harvesting Radio Frequency (RF) from the environment, leveraging the abundant deployments of Bluetooth and Wi-Fi. From the energy harvested, the Wiliot IoT Sticker sends a standard Bluetooth advertising packet. It can communicate securely over Bluetooth to any device that supports BLE, phones, Wi-Fi access points, smart speakers, doorbells even LED lighting.
Privacy + Access Control
Data sent by Wiliot IoT Stickers use the Wiliot Ephemeral ID format, encrypted with a 128-bit AES-based scheme that allows anonymity, confidentiality, and authentication. We have two layers of encryption to enable the safe transit of packets to infrastructure while maintaining the privacy of the application data. Security is enabled by a cloud-based resolver providing access to the data via an API that can be easily integrated with web applications.
With technology as disruptive as Wiliot, it can be challenging to explain the impact of this breakthrough. Yes, now we can enable "Intelligence for Everything" but what does that mean to businesses, how will life change? Check out the below 2-minute video, 'Wiliot Explained':
