The next Wi-Fi innovation will allow for a long-range connection of up to 1 kilometre while using substantially less power. The advantages are attributed to Wi-Fi HaLow, which has now been certified by the Wi-Fi alliance, a global network of companies that provide Wi-Fi.
The significant expansion in the utilisation of Internet of Things (IoT) devices has influenced the design of Wi-Fi HaLow. As the number of IoT applications grows in enterprises and homes, more and more devices will need to be constantly linked to the Internet. According to the Wi-Fi Alliance, Wi-Fi HaLow appears to be an ingenious solution to that need, one that “eclipses existing options.”
When compared to current Wi-Fi, the new kind of Wi-Fi promises significant battery power savings and can create connections up to 1 kilometre distant from the source. Furthermore, Wi-Fi HaLow is compatible with current Wi-Fi devices and builds on existing Wi-Fi protocols. This is a big benefit because it does not necessitate the deployment of any new Wi-Fi connection methods or proprietary technology. In the current architecture, it’s simple to scale.
How does Wi-Fi HaLow work?
Standard Wi-Fi, which we use to connect our gadgets to the Internet, operates at frequencies ranging from 2.4GHz to 5GHz. The enormous bandwidth is due to the fact that these are designed to send a big volume of data in a short amount of time. Instead, Wi-Fi HaLow uses the sub-1 GHz frequency.
Because of the low frequency, the wave can have a longer wavelength, allowing the signals to travel further distances than with higher spectrums. According to the Wi-Fi Alliance, a single Wi-Fi HaLow access point may “beyond a 1 kilometre radius and offer internet connectivity for over 8,000 devices distributed across hundreds of acres.”
As a result, Wi-Fi HaLow lowers data transfer speeds in order to extend the range. Such an application, on the other hand, is ideal for IoT devices, which rarely require large amounts of data to be carried over the Internet. A basic example may be found in any of your home’s IoT gadgets, such as smart door locks, cameras, and air conditioners. These require relatively basic information (such as being turned on/off) to be communicated to them via the Internet, which Wi-Fi HaLow is more than capable of doing.
Similar Wi-Fi HaLow uses can be found in industrial, agricultural, and other settings. Because Wi-Fi HaLow’s low frequency can permeate through shipping materials, it’s great for logistics. It can be used for a variety of applications in a smart city, including traffic monitors and traffic lights. Sensors or devices in agriculture can be put across multiple fields and connected using Wi-Fi HaLow.
As a result, the new technology’s potential is limitless. Wi-Fi HaLow will be the next big enabler with the advent of IoT applications, and we can expect to see it everywhere soon.
