Same in the UK. Although it is a "de-restricted" unlicensed band, the equipment must be type approved and used correctly at appropriate radiated power.

Intentionally blocking legitimate users of the band is not legal, even if the equipment being used to do it is.

Note that in the United States this is illegal depending on your transmitter power level, or if you are interfering with a licensed radio signal (we do have licensed users in the wifi spectrum here).
