Short Description An ISM band device such as a power meter or a wireless doorbell.
I/Q Raw Recording
Audio Sample

An ISM band wireless device signal. Signals include power meters, doorbells, remote-controlled power switches, etc.

A fast and large drift is common to those, as the devices are often battery-powered.

Some of the protocols use ASKAmplitude-Shift Keying or OOKOn-Off Keying Modulation, and some (especially the high data rate ones) use FSKFrequency-Shift Keying.
