It looks like this runs in the 900MHz ISM (US) band, so we'll all need new hardware. The longer range is nice. Interference from other 900MHz transmitters (cordless house phones, baby monitors, etc.) may not be.
I thought microwaves (oven) mostly interfere with the 2.4 GHz band. That's why games of Starcraft always lag out when one of the players starts cooking a hot pocket. That's why it's preferable to use 5 GHz 802.11n or 802.11ac, unless you have walls that block the higher frequencies.
It seems everything old[1] is new again.
