I'm a fan of z-wave and I like their standards better.
Z-wave is on 900+MHz frequency and unlike, Zigbee on 2.4Ghz, Z-wave wont crowd the 2.4Ghz spectrum coz everyone has wifi, etc.
But then i just realized, isn't 800-900 (zwave freqs) the same range most telcos use for 3G/4G etc? Isn't that more crowded with powerful signals from telco stations?
What are your thoughts?
thanks
