Weightless, the Internet of Things Chip, Becomes Less Vaporware

Several months ago, we caught wind of Weightless, a $2 chip that will run for 10 years on a AA battery and communicate to a Weightless base station 10 Km away. Yes, this is the fabled Internet of Things chip that will allow sensors of every type to communicate with servers around the world. It looks like Weightless is becoming less and less vaporware, as evidenced by the Weightless SIG hardware roadmap; Weightless modules might be in the hands of makers and designers in just a few short months.

Weightless is an extremely low-cost wireless module that operates in the radio spectrum previously occupied by analog broadcast television. This is a great place for the Internet of Things, as signals in this spectrum have a lot of range and the ability to go through walls. These signals are sent to a Weightless base station where they are then sent over the Internet to servers around the world.

The Weightless SIG has been hard at work producing new silicon, with the third generation of chips heading for volume production next month. The only thing this chip requires is a battery and an antenna, making Weightless integration for new designs and projects a snap.

There’s one thing Weightless is not, and that’s a free, high-speed connection to the Internet with a $2 adapter. Weightless is designed for sensors that only transmit a kilobyte or so a day – medical sensors, irrigation control, and other relatively boring things. There’s a summary video from the recent 2013 Weightless SIG Summit going over all this information below.
