Wi-Fi Alliance launches new low-power long-range technology




The Wi-Fi Alliance comes with Wi-Fi halow that of an extension to the IEEE 802.11ah technology, among other uses the 900MHz band. As a result, the maximum range is larger than in “normal” wifi, and there is less energy is required to maintain the connection.

This brings the alliance with a type wifi that should be better suited for internet-of-things applications and smart home devices. Wi-Fi halow is in fact an extension of the 802.11ah protocol. It is unclear when the first products with halow will appear, but The Verge gambles on ‘sometime in 2018’.

Besides the 900MHz band halow can also operate in the 2.4 GHz and 5 GHz regions. The 900MHz band has the advantage that it is in a frequency range which does not fall under certain restrictions. The penetration power of a 900MHz signal is larger, which makes it better can come through walls and the like it, even at low power consumption. How much energy than it is and how it further protocol works, it is not clear from the message on the site of the Wi-Fi Alliance.

There is currently a lot to do around connections over long distances at low power consumption. With the cheapening of chips for both transmission and reception, the number of potential applications is increasing. Other well-known low power wide area network-techniques include Lora, Nwave, OnRamp, Platanus, SigFox, Telensa, Weightless -N and -P. Some of these techniques have a maximum theoretical range of up to several tens of kilometers languages, such SigFox and Lora. The techniques that have the furthest range, generally operate in the sub-gigahertz zone at low to very low data throughput rates between the 100-bit per second up to 500 kilobits per second. Also, the techniques often make use of the possibility of the timing of contact, so that the energy consumption of the devices still becomes lower.
