back to article 802.11ax Wi-Fi standard isn't ready, Qualcomm bakes chips anyway

In November 2017, the next version of Wi-Fi, 802.11ax, stalled in the Institute of Electrical and Electronics Engineers's (IEEE's) standards process, but vendors want to push ahead with at least some of its features, according to Qualcomm Wi-Fi product marketing lead Prakash Sangam. Speaking to The Register after the company …

    Every time a wireless standard is about to come out features leak early. Problem is that often those features are compatible only with that company's implementation of them.

      Not just wireless standards ... some of us are old enough to remember the v90 modems that were sold before the standard was ratified (and, I thknk, ended up being slightly different from what the chip manufactures had predicted when they brought out they chipsets)

      @James

      Its not a 'leak'.

      The standards are being discussed and the vendors are part of the discussion.

      They are baking the silicon in anticipation that the spec will not change significantly by the time it is ratified.

      This happens all the time. The vendors don't want to be the last ones coming to market.

    None of those features matter

    Who the hell needs 10 Gbps to a wireless client, though I suppose that markets well to the sort of people who chose an Android phone with 10 cores over ones with a "mere" four or six.

    The headline feature in 802.11ax is OFDMA. Instead of a client transmitting/receiving on an entire 20 MHz channel at a time, they can transmit/receive on an individual subcarrier of which there are now 1024.

    It is as if UPS loaded up a truck with what they were delivering to you, made the delivery, then returned to the depot to pick up what they were delivering to your neighbor, and switched to a system where they can load both you and your neighbor's and up to 1022 other people's shipments in the truck for delivery before having to return to the depot.

    It will be so efficient that they really should recommend in the spec that 802.11ax default to a single 20 MHz wide channel, and require configuration changes to use more so people don't waste the spectrum around them. All these new 5 GHz routers that try to grab 160 MHz just because have made the 5 GHz spectrum as bad as the 2.4 GHz spectrum in dense areas like apartment buildings.

      "Who the hell needs 10 Gbps to a wireless client,"

      Large screen displays (think more digital signage than home tv). Uncompressed streaming hits that with no problem.
