On Tuesday, the Wi-Fi Alliance announced the start of certification for WiFi HaLow. This new feature supports long-distance, low-energy Wi-Fi transmission on the sub-1GHz spectrum, and promises to penetrate walls with a range of more than 1 km.This function is mainly aimed at smart home devices. It is estimated that by 2025, the number of devices connected to the global cloud will surge to more than 30 billion, which is more than double the 13.8 billion IoT devices currently in use.
Edgar Figueroa, President and CEO of Wi-Fi Alliance, said that this is good news for smart home sensors, security cameras, and industrial or agricultural IoT devices. It is also good news for Wi-Fi, especially on Amazon Sidewalk. When new standards like Matter and Matter try to occupy an important place in the smart home category.
Figueroa said in a statement: “The Wi-Fi-certified HaLow further expands Wi-Fi’s leadership in the Internet of Things to address a series of new, safe and interoperable systems that require greater distances and lower power. Use cases. In the growing IoT market, there are more and more opportunities to simplify connections. Wi-Fi HaLow is built on the foundation of universally trusted Wi-Fi, paving the way for emerging IoT applications, enabling homes, businesses, and Industry benefits”.
Wi-Fi HaLow claims longer range and lower power consumption because it sends signals at frequencies below 1GHz, which is much lower than the 2.4 and 5GHz frequency bands used by most home Wi-Fi networks. Although higher frequencies are more suitable for moving large amounts of data, lower frequencies provide better range, which makes the Sub-1GHz spectrum seem to be suitable for sensors and other small data that may need to be sent over long-distance Wi-Fi networks. equipment.
In addition, Wi-Fi HaLow also has a very good performance in terms of battery life. The Wi-Fi Alliance promises: “Including sensors, personal wearable devices and utility meters that require years of battery operation and other applications require low-power connections. Wi-Fi HaLow uses the existing Wi-Fi protocol and provides many benefits that consumers expect, including multi-vendor interoperability, strong WPA3 security, easy setup, and seamless integration with IP networks.”
