There has been a lot of talk on Internet of Things (IoT) or Machine2Machine (M2M) communications – which basically is an intelligent grid of devices connected to each other through the internet. Chips are embedded in the devices enabling them to relay information, take decisions, communicate commands and adjust settings/implement a requisite action(s) accordingly.
As per a report from ABI Research, over five billion wireless connectivity chips will ship in 2013.
What does this mean for the chip biz?
Some basic things that various devices involved in this IoT will include are: wireless connectivity (mostly low power unless one or more of these devices is connected to the mains), sensors, MEMs and control units.
The control units here needn’t be too fancy – efficient and sufficient enough to do the task they are assigned for. They span from low end to high end depending on the computing power required for the control functions - served by MCUs, embedded processors. The sensors (for temperature, pressure, moisture, light etc.) are coupled with accelerometers, gyroscopes and the like.
Connecting to the internet – wirelessly and power efficiently – that will be the key for connectivity stake holders in this space. Nuel has come up with an interesting way to achieve this. It recently announced a white space (unused frequencies during TV channels’ transmission) radio chip for low power communications and come out with a chip to demonstrate the same (it implements the “Weightless’ specifications)
One thing I find interesting about IoT/M2M is that it does not have any defined market space/application. There are potentially several applications, several markets where these can find their way. So, while one can chose to specialize in servicing one market/application, a choice of providing a generic chip/platform (control/sensor/connectivity) for any or combination/integration (SoC) of the components of the basic fabric for any (or at least most of the applications) is also wide open.
However, for the application to catch on, it has to be implemented in an inexpensive way and should be easy to use - and that is where we’ll see some exciting innovation & integration happening
