Hello Mi Fans,
USB Implementers Forum (USB-IF), the support organization for the advancement and adoption of USB technology, today announced the
publication of the USB4™ specification, a major update to deliver the next-generation USB architecture that complements and builds upon the existing USB 3.2 and USB 2.0 architectures.
The USB4 architecture is based on the Thunderbolt™ protocol specification recently contributed by Intel Corporation to the USB Promoter Group (Thunderbolt 3 has always been royalty-free, but specifications weren’t public). It doubles the maximum aggregate bandwidth of USB and enables multiple simultaneous data and display protocols.
For now :
Key characteristics of the USB4 solution include:
• Two-lane operation using existing USB Type-C® cables and up to 40Gbps operation
over 40Gbps certified cables
• Multiple data and display protocols that efficiently share the maximum aggregate
bandwidth (enough video bandwidth for two 4K displays or one 5K display)
• Backward compatibility with USB 3.2, USB 2.0 and Thunderbolt 3
As the USB Type-C connector has evolved into the role as the external display port of many host products, the USB4 specification provides the host the ability to optimally scale allocations for display data flow. Even as the USB4 specification introduces a new underlying protocol, compatibility with existing USB 3.2, USB 2.0 and Thunderbolt 3 hosts and devices is supported; the resulting connection scales to the best mutual capability of the devices being connected.
• USB 4.0 will support charging speeds of 100W of power

The upcoming USB Developer Days 2019 will include detailed technical training covering the USB4 specification and the latest for USB Type-C, USB Power Delivery, and new USB-IF branding strategies.
With the availability of the UFS 3.0,it will be a great deal for our smartphones to be fully equipped with this new standard :
- Super fast Charge
- 4K mirroring
- Fast PC/Mac/Smartphone transfer (as 256Gb would be the next standard especially with new 64/108Mp cameras and 6K recording)
