Wi-Fi is one of main types of a wireless communication now. The majority of communication devices are equipped with this wireless type of communication. But here smart gadgets, i.e. devices with the smart prefix usually do not use Wi-Fi for communication with each other. Exceptions are, but there is not a lot of them.
Vendors reluctantly go for embedding of such communication modules in smart gadgets as Wi-Fi demands considerable costs of energy. And it is a real problem for devices which have to be small, cheap and work in a standalone mode months or even years. But now this problem is gradually solved, apparently. Wi-Fi Alliance is going to certify the Wi-fi HaLow standard, the main for which serves the IEEE 802.11ah specification unconfirmed so far.
In work of Wi-fi HaLow radio frequencies of the range of 900 MHz are used. It will allow devices to work with each other on big, than now, distances with smaller costs of energy. Wi-Fi HaLow will be used in smart houses, smart cars, digital health care and in many other spheres, including the heavy industry.
It is how possible to understand, the range of work of Wi-fi HaLow will be twice more than at standard Wi-Fi. Plus to everything, obstacles like walls will give less inconvenience, Wi-Fi HaLow provides more reliable connection. And here flow capacity will be lower, than at Wi-Fi 802.11ac.
It is planned that the devices supporting Wi-Fi HaLow also will work also in other ranges, including 2,4 and 5 GHz. It will allow to create a steady ecosystem of the gadgets capable to work on a wireless communication. Devices with support of Wi-fi HaLow will be able to be connected to cloud services, including data storages. Also one access point will be able to ensure functioning of thousands of different devices.
Certification of gadgets with support of the new wireless standard will begin not earlier than 2018, but devices will appear much earlier as it is normal and occurs.
