What is the difference between Wiliot and RFID?

Wiliot is not tracking hardware. We differ fundamentally from RFID in both technical architecture and business impact, it’s like comparing a walkie-talkie to a smartphone. RFID operates reactively, finding problems after they occur through periodic scanning. Wiliot enables proactive operations, preventing problems through continuous monitoring and AI-powered forecasts. This translates to moving from snapshot data with gaps to continuous data streams enabling real-time AI and autonomous operations.

Infrastructure complexity varies dramatically between the technologies. RFID needs dedicated readers, fixed infrastructure, and line-of-sight scanning at specific chokepoints, typically achieving only 50% compliance rates in practice. Wiliot leverages existing Bluetooth infrastructure with minimal additional hardware, providing continuous ambient sensing with 99% visibility without manual intervention.

Data richness and global deployment further differentiate the technologies. RFID provides basic identification and location data through snapshot scanning, while Wiliot delivers multi-modal sensing with AI-powered insights including temperature, humidity, light, motion, and continuous location tracking. RFID faces frequency band challenges across countries (865-868 MHz vs 902-928 MHz), whereas Wiliot uses standard globally accepted Bluetooth frequencies.

What is the difference between Wiliot and Bluetooth Beacons?

Wiliot's Ambient IoT approach differs substantially from traditional Bluetooth beacons in both technical implementation and capability scope.

Power models represent one distinction—Bluetooth beacons require battery-powered devices with regular replacement schedules, while Wiliot pixels operate battery-free through RF energy harvesting, eliminating maintenance requirements entirely.

Data processing capabilities vary significantly between the technologies. Traditional beacons provide simple proximity broadcasting for location-based services, while Wiliot delivers a complete sensing platform with temperature, humidity, light, and motion capabilities plus comprehensive AI processing. This enables transformation of 85+ raw data features into actionable business events.

Infrastructure and security requirements further differentiate the approaches. Bluetooth beacons require beacon placement and ongoing battery maintenance, while Wiliot leverages existing ambient Bluetooth infrastructure without additional beacon deployment. Security implementations also differ, standard Bluetooth beacons use basic Bluetooth security, while Wiliot employs AES encrypted packets with rotating private beacon technology designed specifically for crystal-free devices.

Scalability and use cases highlight the strategic differences. Bluetooth beacons are limited by battery maintenance requirements and primarily serve proximity services, while Wiliot is designed to scale to trillions of items without battery replacement. This enables comprehensive supply chain visibility including condition monitoring, asset tracking, and autonomous operations rather than simple location services.

What is the Wiliot roadmap?

Wiliot targets to release one new chip per year. The latest IoT Pixel uses our Version 2 chip which introduces a cost reduction and range increase. With future versions, we aim to further reduce the price point, increase usability, and range further.

Battery-free IoT Pixel

Are Wiliot Battery-free Pixels Bluetooth Qualified?

We are compliant with the Bluetooth standard and qualified as such. We support Bluetooth LE 1 Mbit/s PHY and are a power class 3 device.

Are Wiliot IoT Pixels reusable or single-use?

Due to the sustainability of their materials and low price point, Wiliot IoT Pixels are economically viable for single use. Reusability depends on the application and is a function of the tag conversion process used. Today, our focus is on simple paper stickers, making reuse difficult. In the future, we expect to offer Wiliot Pixels in many conversions such as plastic hard tags and clothing care labels. Since we do association in the cloud, IoT Pixels can be easily reassociated to new items when needed.

Do Wiliot IoT Pixels have storage?

Wiliot IoT Pixels do not store data. If there is no energy nearby to harvest from, then the IoT Pixel won't transmit data. Once sufficient energy is available, Wiliot IoT Pixels will go through the cycle of harvesting, sensing, computing, encrypting, then transmitting data. In certain low energy environments, data could be locally aggregated and logged in a gateway device before being transmitted to the cloud.

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 (the transmission output power, duty cycle, active time) as well as the distance from it and the radio environment. Wiliot IoT Pixels send beacons as fast as a few seconds in a couple of meters range from the tag, under a balanced source of energy.

How much do Wiliot Battery-free Pixels cost?

Wiliot’s assembly and conversion partners buy wafers (chips) from Wiliot and sell finished tags, and therefor set the price of Wiliot IoT Pixels.

While Wiliot owns the design and sells the silicon chips that are embedded into IoT Pixels, our partners with world-class inlay assemblers and converters sell them. To expedite time to market and streamline the production of tags, Wiliot provides tools, reference design, and code to those partners.

Is my IoT Pixel data secure?

Yes, every Bluetooth Advertising packet Wiliot IoT Pixels 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 the safe transit of packets on an infrastructure while maintaining the privacy of the application data.

What are the advantages of a Battery-Free Pixel (BFP) over a Battery-Assisted Pixel?

Since any BLE reader can be configured to read a Battery-Assisted Pixel, and no additional infrastructure is required, the entry price and complexity of tagging things will be dramatically reduced. The BAP is a great springboard to leveraging Wiliot Pixels. We expect it to significantly accelerate the adoption and development of Works with Wiliot solutions. In the long-term battery-free or passive tags will sell in much higher volumes, addressing many more use cases and adding connectivity and intelligence to much lower cost items.

Some of the advantages of a Battery-Free Pixel (BFP) over a Battery-Assisted Pixel:

Cost - Battery-free Pixels (BFP) will be an order of magnitude lower in cost. We expect Battery-free IoT Pixels to cost less than 10c by end of next year.

Size - They are significantly smaller in size (postage stamp size versus business card size).

Longer Lifetime – Battery-Assisted Pixels (BAP) will last up to 3-4 years – a Battery-free Pixel will last as long as the structure of the tag will last, this could be over a decade.

Robust and embeddable – BFP’s are a simpler design, they can survive being frozen at cryogenic temperatures, operate at colder temperatures, can be embedded in other materials such as injection molds, can be more flexible and washable when attached to garments.

Speed – BFPs can broadcast faster than a BAP when close to an energy source. This can be useful when tracking faster moving assets.

Are there any other differences between the BAP and the BFP?The software running on the BAP is different to that running on our battery free product, even though the chip is the same. The flexibility to run different programs on these two tiny computers allows us to capitalize on and optimize the operation of the two different systems and has allowed us to deliver the products to market faster than if the tags had a more basic hardcoded design.
