WUSB [Wireless Universal Service Bus]

This animated TECHTip tutorial is available here.

Here are the basic features of WUSB [Wireless Universal Service Bus]:

• Bandwidth - 480 MBPS-MegaBits Per Second at approximately ~3 meters with scalable architecture to 1 GBPS and higher

• Power/Energy Management - Sleep/Listen/Wake - conserve power when not in use design
• Security - device simple Association and Authentication - encryption at application layer
• Compatibility - backward compatible with wired USB

WUSB has a number of ways to save PM [Power Management]:

• Conserve power during normal operation - turn off radio transmitter during MMCs [Micro-scheduled Management Commands] - host is unaware of device PM-Power Management

• Device(s) go to sleep - extended periods where device does not respond - Host is aware and does not schedule traffic
• Device disconnect - host is aware
• Remote Wake - remote devices use “Remote Wake” to alert (indicate) the host to wake up (turn on)
