Z-Wave is a wireless standard which uses mesh networking to communicate between devices. Mesh networking allows signals to repeat through multiple devices until it gets to the desired home automated device. The result is that Z-Wave networks become more reliable as they grow in size. The distance limit a Z-Wave signal will travel is 100 feet, but that’s in open-air. Through walls, the limit is reduced to approximately 50 feet. Z-Wave uses a RF frequency in the 900MHz range so it won’t interfere with other 802.11 wireless protocols.
Z-Wave is run by the Z-Wave Alliance, which tests and makes sure Z-Wave devices work between multiple companies.
- Wireless and RF signal can travel through walls
- Does not interfere with other wireless signals
- Z-Wave alliance makes sure Z-Wave hardware works between different companies.
- Not open source.
- Wireless distance limit
- Signals are not encrypted which could cause problems for security commands
- Limited to 232 devices
