Protocol Life Cycle
Silicon Labs will add new features based on market requirements and continously improve the Z-Wave Protocol to position the Z-Wave Ecosystem.
The Z-Wave Protocol Life Cycle is a process to provide rapid innovation, new features and robust matured protocol release to Z-Wave Partners.
The Z-Wave Protocol Life Cycle defines the maturation process of Z-Wave Protocol generations and consist of three phases divided in five Life Cycle stages.
Ascent Phase (BETA)
Silicon Labs releases new Z-Wave protocol generations (branches), i.e. initial BETA release of a Z-Wave Protocol generation that will introduce major new features/functions or support for a new Z-Wave Single Chip generation.
Maturity Phase (ACTIVE/MAINTAINED)
Each new generation will generate follow on matured releases to resolve protocol issues prioritized by Silicon Labs and based on input from Z-Wave Alliance Partners.
Decline Phase (MONITORED/OBSOLETE)
After a period of 17-24 months in the maturity phase a branch/release is discontinued and for an additional period (up to 24 months) a discontinued branch/release will be monitored since products based on this branch may still be shipping or under warranty in the field.
