HaLow is a new WiFi technology with lower power consumption, longer transmission distance and wider coverage. It has strong wall penetration capability and is farther away from the current WiFi technology. WiFi HaLow expands the use of WiFi for small, battery-powered wearable devices, deployments in industrial facilities, and applications in between. It is more suitable for low power, long distances. IoT device.
In most homes, Wi-Fi has become a very important connection, but many smart home products have not been connected by Wi-Fi. Why?
The reason why many companies are reluctant to use Wi-Fi connections for their products, one of the biggest problems is that Wi-Fi consumes a lot of power, which is a few months of small size, low price or one charge. Even a year of smart home products can't afford it.
Therefore, this is also the problem that the entire Wi-Fi Alliance has been working on for so many years. And now the Wi-Fi Alliance brings a new Wi-Fi protocol that can run on low-power devices, while spreading farther and more through the wall. Basically, the new Wi-Fi protocol has made significant progress in power consumption for smart home and IoT devices.
It is reported that this new Wi-Fi protocol is called Wi-Fi HaLow and will be an extension of the upcoming 802.11ah standard. The Wi-Fi Alliance plans to launch products that support the HaLow protocol in 2018.
In essence, HaLow is a response from the Wi-Fi Alliance to Bluetooth, which in the future can be a necessary connection for fitness tracking devices, sensors, cameras and a variety of other professional products. HaLow needed a more convincing way to conquer vendors and consumers than Bluetooth, while Kevin Robinson, vice president of marketing for Wi-Fi Alliance, said: "Wi-Fi HaLow will offer similar power consumption advantages as other connections."
If HaLow really has ultra-low power consumption as promised by the Wi-Fi Alliance, it will have the advantage of being more powerful than Bluetooth and having a longer transmission distance. After all, once HaLow is connected to the router, it is the whole face. the Internet. At present, the outside world has certain doubts about the performance of HaLow. At the same time, the popularity of existing products needs to be upgraded. The products including smartphones and routers need to upgrade Wi-Fi chips to support HaLow, but we believe that over time The transition, like the current 5GHz Wi-Fi, has begun to be gradually accepted by more users.
In addition, another reason why HaLow has more potential is that it can work in the 900mhz frequency band, which is more popular and better than the existing Wi-Fi 2.4GHz and 5Ghz (but like Wi-Fi, HaLow There will be interference in some cases).
Of course, it is not that HaLow has no shortcomings. For example, HaLow is not good at fast data transmission. After all, it is not for wireless Internet development, so the data transmission requirements are not large. Hardware vendors using HaLow technology are at the expense of network transmission speeds in exchange for lower power consumption.
In fact, HaLow has begun to emerge in the smart home field two years ago. Now that the Internet of Things and smart home have begun to become mainstream, HaLow has also come to the best time to show their skills. Robinson said that HaLow will play an important role in the Internet of Things. Technology HaLow is not the only connection, but it will also be the most important component.
