January also marks Wiliot's second anniversary. Birthdays are a good time to reflect back on milestones that were achieved during the year. When Wiliot was founded our vision was to create a new class of communication devices that would power themselves, be so inexpensive that they could be disposable and produced in quantities that would eventually grow, not to billions, but to trillions. We wanted to bring cloud connectivity to the things that were previously not yet part of the Internet of Things, such as packaging and products like clothing to which you couldn’t attach a radio. Bluetooth was the obvious standard to start with because the infrastructure is everywhere. Making that device using the same techniques pioneered by the RFID industry was theoretically the best way to achieve the size and cost goals. However, this would require that the entire system be shrunk from a printed circuit board crowded with chips, capacitors, a battery and a crystal, to a single integrated circuit chip glued to an antenna. These would be assembled in vast quantities by machines designed to perform the whole process with minimal intervention, without expensive “clean rooms”. At the start of 2018 we had some ideas on how to do this, but no proof that it was possible.
