The lower RF frequencies of Wi-Fi HaLow, which range from 850 to 950 MHz (compared to 2.4 or 5 GHz for Wi-Fi 4 or Wi-Fi 6), and range-optimized modulation and coding schemes, enable Wi-Fi HaLow devices to exceed a range of 1 km. Wi-Fi HaLow operates in the sub-1-GHz band with narrower channels (from 1 to 16 MHz), while Wi-Fi 4, 5, and 6 use channels with bandwidths from 20 to 160 MHz. The table below presents a comparison of Wi-Fi HaLow with Bluetooth, showing how the two protocols stack up. This comparison considers two separate Bluetooth versions: Bluetooth Classic and Bluetooth Low Energy (BLE), also known as Bluetooth 4.0. It is unlikely to support IoT use cases that rely on large numbers of low-power devices connected over long distances. What About Bluetooth?īluetooth is a popular wireless personal-area-network (WPAN) protocol used in many consumer devices such as smartphones, wireless headphones, and portable speakers for short-range communication. Like other modern Wi-Fi technologies, Wi-Fi HaLow also allows for multi-vendor interoperability, easy setup without disrupting existing Wi-Fi networks, and the latest Wi-Fi security. It can deliver all of the benefits that consumers have come to expect from Wi-Fi today, while providing a tenfold increase in connectivity range as well as significantly lower power consumption for thousands of devices connected to the same access point. Wi-Fi HaLow facilitates a more comprehensive approach to IoT wireless connectivity. Wi-Fi HaLow, which incorporates IEEE 802.11ah and is one of the latest Wi-Fi protocols in the IEEE 802.11 family, was engineered specifically to meet the unique needs of IoT environments. The first thing to note is that not all connectivity is the identical. With the world of IoT becoming an essential part of our lives, businesses must understand how to support the growing connectivity needs that come with this new era. Last year, spending on IoT reached a whopping $300.3 billion and it’s expected to reach USD $650.5 billion by 2026. Today, the Internet of Things (IoT) is relevant to almost every industry and is one of the fastest-growing sectors of IT. This article is part of the TechXchange: IoT & Narrowband Communications.
