Abstract

A wireless network device comprises a wireless signal driver, an application-driver framework that includes a bidirectional interface and an application interface. The application-driver framework is configured for application-agnostic and driver-agnostic communication. The bidirectional interface communicatively couples the wireless signal driver to the application-driver framework. The bidirectional interface includes an abstraction layer via which driver-agnostic command signals and driver-agnostic event signals are communicated with the application-driver framework and via which driver-specific command signals and driver-specific event signals are communicated with the wireless signal driver. The application interface is configured to interface with applications and with the application-driver framework. The application interface is configured to communicate application-agnostic command signals and application-agnostic event signals with the application-driver framework and to communicate application-specific event signals and application-specific command signals with the one or more applications and the application-driver framework.
