Access Control

overview

Long range, low power, secure, easy-to-install lock solutions

We provide technology that both simplifies design and speeds time-to-market for developers of access control products. Technologies include support for multiple protocols both standards and none standard based in both sub-GHz and 2.4 GHz frequencies. Our technologies also support easy device commissioning, device security, long battery life, and robust RF performance in crowded environments all help ensure successful deployments in the consumer market space.

Developing access control systems

Wireless protocol requirements may depend on whether the product will operate 'standalone' or be integrated into a centralised access control system. Multiprotocol wireless solutions can offer simplified integration with other systems and offer certain advantages in differing RF environments.

Support for authentication requirements
When designing a wireless lock, you can choose from a variety of authentication options:

• 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 and unlike mechanical locks, developers can use a single authentication technology, or several technologies. Integration with mobile or tablet applications or centralised access systems can offer user customizations such as controls that automatically lock a door as it closes or trigger events in other systems including security lighting, scenes, and so forth.
