The WiFi Alliance recently introduced a new low-power, long-range WiFi solution called Wi-Fi HaLow™ that could shake things up for the Internet of Things (IoT).

What is Low-power WiFi?

Low-power WiFi operates on a lower frequency, specifically 900MHz (0.9 GHz). This enables the signal to travel longer distances, while consuming even less energy, thereby increasing the versatility of WiFi.

There are currently 6.8 Billion devices connected to WiFi, due in part to the growth of the Internet of Things, which is connecting all sorts of devices over the wireless network. And low-power WiFi could open up a whole new realm of possibilities with how those devices connect to each other and to the network.

Pros of Low-power WiFi

  • Increased range – nearly 2X more at line of sight
  • Better at penetrating through walls and other obstructions
  • Lower power consumption

Cons of Low-power WiFi

  • Not suitable for data-intensive applications
  • Possible interference from other wireless devices (baby monitors, cordless phones etc.)

Low-power WiFi for IoT

Low-power WiFi has the potential to create new opportunities for IoT by offering the ability to connect thousands of devices using single wireless access point. This could enable simpler connections to enhance services and applications like:

  • Smart Homes
  • Wearables
  • Home Security
  • Industrial Applications
  • Smart Cities
  • Connected Cars
  • Digital Healthcare
  • Agriculture
  • Retail

WiFi HaLow has a lot of promise for the connected home and the Internet of things. Stay tuned for more news as the 900Mhz standard takes off. And in the meanwhile learn more about WiFi Bands and the two most widely used WiFi bands today: 2.4GHz vs 5Ghz.
