Wireless solutions for secure and ease to use smart door locks 

We provide solutions that both simplify design and speed time-to-market for developers of smart door locks. Our secure wireless solutions include Z-Wave, Zigbee, Thread, Bluetooth, Wi-Fi and proprietary RF and support multi-protocol capability with easy device commissioning. Our products are designed for long battery life, broad peripheral support capability, and reliable, robust RF even in unfavorable and busy RF environments.  Our protocol stacks are built to support the numerous smart home ecosystems to ensure an optimal end user experience.

Developing smart door locks

Wireless protocol requirements depend on whether the product will operate 'standalone' or be integrated with other smart home or home security system products. Multiprotocol wireless solutions can enable smartphone Bluetooth connectivity while also being a part of a larger smart home network.

Peripheral support for authentication requirements
When designing a wireless door lock, you can choose from a variety of authentication options, depending on the user experience:

  • PIN codes: Typically referred to as "digital keypad locks," these locks use a numerical code (usually 4-12 digit numbers) for authentication.
  • Security tokens: Keyless locks scan a security token for authentication. The token is usually a proximity card that is small enough for consumers to keep in their purse or wallet.
  • Biometrics: Locks can be designed to allow access by using an owner's physical unique characteristics such as a fingerprint, hand geometry, eye scan or voice.

The Silicon Labs wireless platform supports a broad set of peripherals enabling door lock authentication mechanisms.

Long battery life predominantly depends on the power consumption and the use frequency of the lock motor and the wireless communication. Our wireless solutions provide low operation with fast wake-up times, enabled by functionality such as Z-Wave FLiRS (Frequently Listening Receiver Slave) for door locks. Developer tools in Simplicity Studio include an energy profiler to ensure full understanding of the wireless door lock application power profile and to enabling detailed optimizations by developers.

Easy commissioning of smart door locks can either be achieved by the use of our Z-Wave SmartStart technology or from our multiprotocol capability that leverages Bluetooth with Smartphones to commission devices into Zigbee or Thread networks
