ZigBee may soon start looking a bit Threadbare…
Today Google and Nest launched the Thread Group – a new wireless network for home automation. It’s not the first and it won’t be the last, but it has some important names behind it. The big two are Google and Nest, not least because Nest’s products may already be using it. But others in the consortium are interesting. ARM is there. Today they power most of our mobile phones, providing the IP behind the processors in billions of chips. But they have a vision of being the microprocessor architecture of choice for the Internet of Things. They processors will be smaller, cheaper and lower powered, but will provide the first opportunity for chip vendors to think about trillions. ARM’s inclusion in the group is an obvious step in their process of acquisition and investment in IoT companies.
Samsung are there (aren’t they always), but so are some very large names in home automation, such as Big Ass Fans and Chubb. And what must be worrying the ZigBee community is that Freescale and Silicon Labs complete the list of founder members.
The important point here is that Thread is not ZigBee. It works in the same spectrum and can use the same chips. It is also a mesh network. But it is not compatible. As the Thread technology backgrounder says, they looked at other radio standards and found them lacking, so they started working on a new wireless mesh protocol. To put it more crudely, it’s Google and Nest saying “ZigBee doesn’t work”. Continue →
