Z-wave is a wireless protocol which links a number of over 2600 different Smart Home Devices together. However, unlike your WiFi network or Bluetooth, Z-Wave is a software and hardware solution designed specifically to support a Smart Home environment. It differs significantly from WiFi and Bluetooth as it is a mesh network, meaning that each device repeats each signal it receives. Consequently the more Z-Wave devices you have, the stronger and more reliable the network is.
The signal the devices send is short range in itself, (up to approximately 330ft but a range of 50ft or less is recommended for solid reliability) but when many small devices are operating in your home, the mesh ensures that distance between the originating device and the intended receiver is no problem. This means that unlike other wireless communications, the more devices enhance reception rather than taking up bandwidth from a router which also serves your other connected devices, internet access, et cetera.
