back to article USB Forum submits itself to electrical probing

The USB Implementers Forum (USB-IF) has ticked off a small-but-significant milestone by submitting its new standards to the International Electrotechnical Commission (IEC). As we've previously noted, the USB-IF has revealed a 10Gbps-capable USB-C connector, and also an ambition for two-way power flows at up to 100W over USB. …

    USB 3 is a disaster - WiFi and other wireless interference is awful

    Even Intel says so:

    Goodbye WiFi and wireless devices if you try to use USB3 -- Intel's OWN report here -- http://www.intel.com/content/www/us/en/io/universal-serial-bus/usb3-frequency-interference-paper.html

      No, it seems to be saying that shielding is required to avoid interference. Buy quality hardware instead of low priced junk and you won't have these problems.

      Only on 2.4GHz channels. No true Reg reader would use such a congested frequency, when there's a perfectly good 5GHz alternative.

        Good luck finding a Bluetooth device that doesn't use 2.4 GHz! Not to mention, some of us wish to leave our homes on occasion, and can't control who uses 2.4 GHz wifi.

        Only if your hardware supports 5GHz. How many Reg readers use old laptops with only 801.22 a/b/g support?

      While concern over issues like this is healthy, I doubt that your fears are founded in this instance.

      First of all, the spec is broad ranging, covering everything from the connectors, to the voltages, to the cable composition, which doubtless includes appropriate shielding and grounding. In addition, regulatory bodies, such as the Federal Communications Commission, would seriously frown upon the widespread proliferation of RF jamming technology, even if the jamming was a side effect.

      I feel like there may be some use for the inverse of the saying, "If it sounds too good to be true, it probably is."

    100W ?!?!?

    Er, how? Not at 5V I hope, or we're going to have cables the size of our fingers to deal with...

      Re: 100W ?!?!?

      From looking up the standards it appears devices can negotiate their power capabilities, so lower power devices can in theory have smaller cables that won't melt since their power will be capped.

      In theory

      5A max, so you get 60 watts at 12v or 100 watts at 20v.
