Abstract
A wireless network device comprises a physical layer (PHY) module that sends and receives packets wirelessly, a first media access control (MAC) module that wirelessly communicates with a second wireless network device in an ad-hoc mode via the PHY module, and a second MAC module that wirelessly communicates with an access point in an infrastructure mode via the PHY module.
Claims20
A wireless network device comprising:
- a physical layer (PHY) module that sends and receives packets wirelessly;
- a first media access control (MAC) module that wirelessly communicates in an ad-hoc mode or a mesh mode with a second wireless network device via the PHY module;
- a second MAC module that wirelessly communicates in an infrastructure mode with an access point via the PHY module;
- and
- a physical dispatcher module that directs packets from the PHY module to the first MAC module or the second MAC module, wherein (i) packets wirelessly communicated by the ad-hoc mode or the mesh mode are directed to the first MAC module and (ii) packets wirelessly communicated by the infrastructure mode are directed to the second MAC module.
