How does the new 802.11.ah HaLow WiFi standard differ from current WiFi?

I know that a different frequency is used, but other than that what does HaLow do better (or at least differently) from current WiFi standards?
It uses the old cordless phone frequency of 900Mhz, which is much better at passing through walls and floors without losing signal strength. With the growth of the Internet of Things, this will help keep everything in your house connected with less "dead spots" where the signal is too weak to rely on.
The article I saw on NetworkWorld has a good summery: "The new standard, 802.11ah, combines lower power requirements with a lower frequency, which means that those signals propagate better. That offers a much larger effective range than current Wi-Fi standards, which operate on 2.4GHz and 5GHz frequencies, and lets the newer technology penetrate walls and doors more easily."
