Will low-power Wi-Fi be the saviour of the IoT?

The other day one of my colleagues at Imagination pulled from her pocket an old, battered, but clearly much cherished, music player. I couldn’t help but comment on its age, but she was proud to still be using it and that the music contained on it was six years old! Retro, is the new cutting edge – you heard it here first…

However, it shows that if you’re not connected, you’re effectively stagnating. You’re not moving forward and not discovering anything new. If you have to actively make an effort to connect your device, after a while you won’t bother and you’ll be stuck in a rut, always be playing the same tune.

Wireless communication has changed everything, and we now expect that all our devices, such as our tablets, smartphones, TVs and speakers are all connected. In fact, it now seems hard to conceive of a product not being online. And this connectivity is only going to increase as everything from security cameras, to fridges, our lights and our thermostats all gain chips for communication.

This connectivity is going to extend out of the home, into sensors that will be, literally, out in the field. They will enable smart farming, with precision agriculture, providing hyper-local weather forecasting data and soil quality analysis to increase agricultural efficiency. Meanwhile, sensors will be used to create our smart cities: smart grids will detect and react to local changes in usage, while smart parking will reduce congestion and pollution.

In healthcare, we are going to see the introduction of ‘smart beds’ that can detect when they are occupied and when a patient is attempting to get up. In the home, medical devices will detect when medication has been taken, and send information to the cloud for later analysis, or directly monitor a patient and alert a care team if required.

This is, of course, the Internet of Things.

Many of these devices will not be connected to a power source and require batteries. As such, very low power consumption will be a de-facto requirement. The choice of connectivity technology, therefore, has to take this into account and be built from the ground up to ensure this.

In our webinar, we’ll examine how low-power Wi-Fi will be the technology of choice for the IoT and explain how repurposing existing Wi-Fi cores isn’t ideal.

In the 30 minute presentation we will look at:

  • various applications of Wi-Fi in sensor-based networks
  • the typical power consumption scenarios for sensor networks
  • the requirements of Wi-Fi silicon to meet long battery-life demands
  • Imagination’s low-power Ensigma Wi-Fi solution and its power consumption metrics

From this, you’ll be able to make an informed choice when selecting a technology for your IoT SoC, and also help you know what you’re looking to purchase a device that meets your needs.
