Who is Wiliot?
We are a semiconductor and cloud company that designs and markets a wireless computing and sensing solution. This solution comprises integrated silicon and cloud computing technologies enabling battery-free operations at a fraction of the cost. Our vision is to securely connect the physical and the digital world, using wireless RF technologies.
Does Wiliot sell tags?
No, but Wiliot’s partners do. Wiliot owns the design and sells the silicon chips that can be embedded in tag inlays. Wiliot does not manufacture or commercialize inlays or tags. Wiliot is partnering with world class inlay assemblers and converters who sell them. To expedite time to market and streamline the production of tags, Wiliot provides tools, reference design, and code to those partners.
How much will Wiliot tags cost?
Wiliot does not directly sell tags. Assembly and conversion partners will buy wafers (chips) from Wiliot and sell finished tags.
Can I get samples?
Tags will be in controlled release in 2020, exclusively for members of the Wiliot Early Advantage Program (EAP). General Availability and associated sampling is targeted for 2021. Wiliot is sharing regular progress updates in their newsletter (which can be subscribed to here).
What is the Wiliot roadmap?
V1.0 of Wiliot Tags will be used in controlled release in 2020. Wiliot targets to release one new chip per year. The focus on v2.0 are cost reduction and range increase. V3.0, planned for 2022, aims to further reduce the price point and increase usability and range further.
What is the EAP? Can I join?
The Early Advantage Program is designed for a small number of technology early adopters. In 2020, Wiliot will focus on the existing EAP members and their projects, supporting large scale pilot deployments. The program is currently fully subscribed and is not accepting new applications.
What’s the difference between Wiliot and RFID?
- Low cost infrastructure
- Wiliot generally uses existing infrastructure (phones, wi-fi, smart speakers …)
- When you need special functionality (BLE to Cellular/AoA the cost for the infrastructure is a lot lower and there is much more choice)
- Cloud sensing
- Wiliot tags have a compute engine and they also leverage the cloud so they can sense temperature and pickup
- In the future, Wiliot will build on an AI framework to sense many other things
- Entire product life cycle
- Wiliot tags can adapt to different conditions and because they talk to consumer devices, they can span the entire product lifecycle – RFID tends to work in siloed non-consumer applications
- Wiliot tags are encrypted, non-trackable, can be used to authenticate products and can be used to implement GDPR standards – RFID isn’t secure
- Don’t rely on people doing anything
- Unlike RFID or NFC or QR Codes no need to tap or scan -which is good for enterprise and consumer applications
What does the chip do?
The chip consists of 5 main components: an energy harvester that capture ambient RF energy, an integrated sensing unit, a security unit, a processing unit and a Bluetooth transmitter.
What services are you running on the cloud?
Wiliot cloud is a key element of the Wiliot solution. It provides limited yet essential services that are critical for scalability: security (privacy, confidentiality, and authentication), sensing (calibration, data processing, digital smart sensing) and product lifecycle management.
Can I use Wiliot tags without the cloud service?
No. Wiliot offers a solution comprising of two essential components: chip and cloud. These are tightly integrated by design and for reasons of security and functionality cannot be used independently. Physical tags with Wiliot chips send encrypted and authenticated packets over the air while the cloud provides decryption, authentication and smart sensor processing. Tag data can be accessed from the Wiliot cloud through a RESTful interface. The cloud ensures data remains secure, private and authentic, and generates actionable information about: temperature. Movement and pressure/weight.
Can I register to receive a notification on the availability of samples or GA?
Currently, we are sampling customers through participation in the Early Advantage Program. We are planning to release the product to the mass market in late 2020. To be the first to receive product information and Wiliot tag availability notifications, be sure to fill the contact form on our website (www.wiliot.com) and subscribe to Wiliot news.
What type of beacon protocols do you support?
We support the Wiliot Ephemeral ID format (WEID), a power efficient format designed by Wiliot to securely send private and encrypted ID, in addition to sensor data. This format uses the same Bluetooth Low Energy non-connectable non-scannable undirected advertising packets that are part of the Bluetooth 4.x and 5.x standard, as used by other Bluetooth beacons.
How do I access the tag data?
The digital identity and digital activity of physical products can be accessed through a RESTful API interface to the Wiliot cloud.
What sensors do you have on chip?
The chip produces low level data for temperature and a movement sensing. The actual sensing is performed in the cloud. The chip has a detector on the digital I/O that can detect a change of state on a mechanical trigger. It can be built into a sticker that is torn when opening an envelope to detect such an event. The raw data measured by the physical sensors is then combined with cloud-based machine learning algorithm, which translates these raw values onto the corresponding physical domains (e.g. pick-up/movement) through algorithms that are self-learning and improving over time.
Is there a CPU in your chip?
Yes, Wiliot chip integrates an ARM Cortex M0+ CPU.
Do you support security?
Yes, every Bluetooth Advertising packet Wiliot tags send out is encrypted with a 128-bit ECB AES-based scheme that allows anonymity, confidentiality, and authentication. Wiliot has two layers of encryption to enable safe transit of packets on an infrastructure while maintaining the privacy of the application data.
What tools and processes can be used to manufacture Wiliot tags?
Wiliot is leveraging the same processes, tools, and machines that are used to build UHF RFID and NFC tags. Exploiting the know-how and economies of scale from this industry is a fundamental aspect of Wiliot’s technology.
What external components do you need for the tags to work?
None, it’s just a chip and the antenna. Some application may require external sensing material (e.g. a force sensing material) to implement certain functionality.
What is the size of the tag?
Size of the tag depends mostly on the antenna size, and is function of the environment, the application, and the manufacturing requirements we don’t directly control. It can be as small as a US postage stamp (< 5 cm2)
What sources of energy do you use?
We use the ambient energy that propagates in space through Radio Frequency waves. Specifically, we harvest cellular, Bluetooth, Wi-Fi and other 2.4 GHz connectivity technologies (e.g. Zigbee, Thread, etc). The specific bands supported are a function of the design of the harvesting antennae. The Wiliot chip supports harvesting from up to 3 different bands simultaneously.
What is the range?
The range can vary depending on the radio environment and material upon which the tag is mounted. The target for v1.0 is 3 meters. In some cases, assuming a balanced energy source and good radio conditions, tags may be visible up to 6-8 meters. Subsequent chip versions aim to improve the range (v2.0 target is 10m-20m).
How frequently can you transmit a beacon?
Beacons are transmitted when there's enough energy collected. This is a function of the energy source pattern (transmission output power, duty cycle, active time) as well as the distance from it and the radio environment. We can send beacons as fast as few seconds in a couple of meter range from the tag, under a balanced source of energy.
What is the lifetime of the tag?
The lifetime of the tag is driven by material and manufacturing process of the tag assembly more than by the life expectancy of the chip. We suggest discussing details with inlay assembly house as this can vary depending on the requirements and price may be affected consequently. The industry today can provide options for the tag lifetime that can go anywhere from 6 months to 10 years.
What is the behavior of the tags on surfaces like metal, or liquid containers?
As with RFID, different inlay, antenna designs and special gap fillers may be required to support on-metal/skin/liquid/glass applications. Metal and liquids are the most challenging material that affect RF environments in both the harvesting and transmission path. Issues are comparable between Bluetooth tags and RFID tags.
