The organization responsible for promoting the most common external data connection standard is trying to fight back toThunderbolt 3
With all due respect to wireless communication technologies such as Bluetooth or WiGig, it is likely that none of them will in fact threaten the "USB The old and familiar wire as the most common and accepted way to move information from place to place - but that does not mean that there are no plans to further improve the capabilities of the market-leading device.
The USB-IF organization, which is responsible for its technological advancement and includes representatives from most major technology companies, has announced the release of an almost final version for the USB 3.2 standard, which will be a slight upgrade to the familiar USB 3.1 with full backward compatibility and one key feature It can not be ignored - increasing the maximum available bandwidth for use from 10 gigabits per second today to 20 gigabits per second, half of what theThunderbolt 3 but also 4 times what is available inUSB 3.0 that continues to be the most commonly used default.
The future device will reach twice the speed without any physical change to the USB Type-C connections we know today - simply by using the second transmission and reception channel available basically in the interface, and until now was reserved exclusively for the "alternative" use modes supported by it: Video signals in HDMI and DisplayPort standards, MHL signal transmission and transmission signalsThunderbolt 3. Using the full speed of the USB standard 3.2 will not allow signal transmission Video At the same time, naturally, but this is probably a compromise that many will be willing to accept - especially since this is not about any physical limitation, but about the addition of an additional work mode along with all the diverse work modes that already exist within the technology.
In the framework of the coding mechanisms accepted in the modern era,USB 3.2 will be able to provide very impressive theoretical transfer speeds of approximately 2 / Gbps.
USB 3.2 will also provide backward compatibilityUSB 3.1, theUSB 3.0 andUSB 2.0 as stated, although to enjoy the maximum speed it will require cable USB Type-C, which has been properly ratified by theUSBWhich may prove to be a rather problematic requirement, considering that the market is currently loaded with cables of various kinds that are not clear who examined them and how, as part of the inherent disadvantages of technology that is free and open to everyone. The new standard is expected to be commercially available towards the end of next year or at the beginning of 2019, and we can only hope that by then the appropriate way and reason will be found for some order in the market that will make it easier for us all to understand what we are getting and when.
The current announcement comes not long after Intel announced that it would become the "Thunderbolt Its advanced 3, which is also based on the standard physical interface of theUSB Type-C (although it needs dedicated controllers on the two devices it connects to operate), is free and available to everyone - so that each manufacturer can choose to provide controllers to operate it for the various products, plus the intention to make the controllers a built-in part of future chipsets.
In such a situation, it is not entirely clear whether USB 3.2 will have any advantage over the X-Thunderbolt When it becomes available for mass distribution - but we are still happy that there is a readiness to continue Development Capabilities in the computer market, storage drives, computers, and docking stations of tomorrow.
