Z-Wave low-power, short-distance wireless standard that uses the 2.4GHz band is part of the ISM [Industrial, Scientific, and Medical] license-free radio bands [see below]. Additional frequencies of the ISM band include the 900MHz band, and the 5.8GHz band. The european version operates in the 860MHz band.
Z-Wave modulation may be FSK, GFSK, Narrowband and operates out to about 100 feet in free space. A simular, competing wireless standard in the same bands is; ZigBee.
The Z-Wave Specification may be down loaded from the Z-Wave Alliance
The only IC or device manufacturer to date is Zensys, which developed the specification.
Companies which manufacture Wireless ICs are listed on the RF component manufacturers page
