Wi-Fi Alliance rebrands 802.11ac as Wi-Fi 5, picks 802.11ax as Wi-Fi 6

The Wi-Fi Alliance today announced a significant rebranding of the "802.11" Wi-Fi standards that have long served as a source of potential confusion for users: Going forward, the current 802.11ac standard will be known as Wi-Fi 5, while its successor 802.11ax will be known as Wi-Fi 6, establishing a generational terminology that — like Bluetooth 3, 4, and 5 — will be easier for customers to remember and understand.

[...] Today's announcement is significant not just because of its impact on currently popular Wi-Fi standards, but also on one that's been on the fringe: 802.11ad. Also known as WiGig, 802.11ad notably depends on an extra, 60GHz millimeter wave wireless antenna to boost speeds of compatible devices in the same room as the router. A handful of routers and devices, including wireless VR adapters, have adopted 802.11ad over the past year or two.

But the announcement makes clear that the Wi-Fi Alliance sees 802.11ax, not 802.11ad, as the next stage of Wi-Fi's evolution. 802.11ax has no need for the extra antenna, instead making more efficient use of the 2.4GHz and 5GHz bands already used by 802.11ac — err, Wi-Fi 5. Wi-Fi 6 promises up to 11 Gbps speeds across three or more devices, with a single Wi-Fi 6 device achieving up to 5 Gbps.

In a statement to VentureBeat, the Alliance explained how Wi-Fi 6 and WiGig will coexist:

"Wi-Fi 6 and WiGig, based on 802.11ad and eventually 802.11ay, will continue to evolve in parallel and remain strong complements to one another within the Wi-Fi portfolio of technologies. We fully expect some products to integrate Wi-Fi 6 and WiGig, which will remain a distinct brand to indicate products that support 60 GHz Wi-Fi for multi-gigabit, low-latency connectivity."

Qualcomm's new Wi-Fi chips are meant to rival 5G speeds

Qualcomm is launching a family of chips that can add incredibly high-speed Wi-Fi — at speeds up to 10 gigabits per second — to phones, laptops, routers, and so on. It's the start of a new generation of this super-fast Wi-Fi standard, but it isn't going to be used to speed up your typical web browsing. And whether it catches on at all remains an open question.

[...] WiGig relies on a connection standard known as 802.11ad, which can hit speeds up to 5 gigabits per second over close to 10 meters, according to Dino Bekis, the head of Qualcomm's mobile and compute connectivity group. Qualcomm's latest chips move WiGig up to a new generation of that wireless standard, called 802.11ay, which Bekis says can reach speeds twice as fast, and can do so up to 100 meter away. The Wi-Fi Alliance says the new standard "increases the peak data rates of WiGig and improves spectrum efficiency and reduces latency."

So why not just use this as normal Wi-Fi, given how fast it gets? Because that range is only line-of-sight — when there's literally nothing in the way between the transmitter and the receiver. This high-speed Wi-Fi is based on millimeter wave radio waves in the 60GHz range. That means it's really fast, but also that it has a very difficult time penetrating obstacles, like a wall. That's a problem if you want a general purpose wireless technology.

[...] It's not clear if this will really catch on, though. While there's definitely room for adoption from VR gamers, the earlier version of this tech has found minimal pickup in its couple years on the market. Asus recently made interesting use of it with the ROG Phone, which is designed for gamers. And Qualcomm says it's working with Facebook to use this tech for its Terragraph project, which wirelessly delivers home internet connections.

With 5:1 "visually lossless" compression, 10 Gbps could be enough for 5K @ 120 Hz.

Netgear Announces Nighthawk RAX80 and RAX120 802.11ax AX6000 Routers

Netgear has announced imminent availability of their first 802.11ax router - the 8-stream Nighthawk RAX80, along with the technical details, pricing, and other information. In addition, they have also unveiled the 12-stream RAX120. While the RAX80 will be available for purchase this month, RAX120 will make it to retail in Q1 2019.

802.11ax has had an uphill adoption curve. Silicon vendors have been announcing draft-compliant chipsets since late 2016 (Quantenna - Q4 2016, Qualcomm - Q1 2017, Broadcom - Q3 2017, Marvell - Q4 2017, and Intel - Q1 2018). Device vendors were not far behind, with Asus going public about its plans to release a router (RT-AX88U) based on the Broadcom platform as early as September 2017. A year after the announcement, the RT-AX88U finally made it to retail at a $350 price point. D-Link also gave a sneak peek into their AX6000 and AX11000 routers based on the Broadcom chipset at the 2018 CES.  In the meanwhile, we have had deployments of the Qualcomm chipset in the carrier gateways from KDDI and NEC in Asia, as well as enterprise access points from Huawei and Ruckus Wireless.

[...] It must be noted that the aim of 802.11ax is not to target peak data-rates, but, improve the aggregate performance over several simultaneously active clients. The OFDMA-enabled[*] simultaneous transmission to several users results in increased efficiency. Thanks to the lowered waiting time, the battery life of client devices also increases.

CES 2019 Quick Bytes: Consumer 10nm is Coming with Intel's Ice Lake

We've been on Intel's case for years to tell us when its 10nm parts are coming to the mass market. Technically Intel already shipped its first 10nm processor, Cannon Lake, but this was low volume and limited to specific geographic markets. This time Intel is promising that its first volume consumer processor on 10nm will be Ice Lake. It should be noted that Intel hasn't put a date on Ice Lake launching, but has promised 10nm on shelves by the end of 2019. It has several products that could qualify for that, but Ice Lake is the likely suspect.

At Intel's Architecture Day in December, we saw chips designated as 'Ice Lake-U', built for 15W TDPs with four cores using the new Sunny Cove microarchitecture and Gen11 graphics. Intel went into some details about this part, which we can share with you today.

The 15W processor is a quad core part supporting two threads per core, and will have 64 EUs of Gen11 graphics. 64 EUs will be the standard 'GT2' mainstream configuration for this generation, up from 24 EUs today. In order to drive that many execution units, Intel stated that they need 50-60 GB/s of memory bandwidth, which will come from LPDDR4X memory. In order for those numbers to line up, they will need LPDDR4X-3200 at a minimum, which gives 51.2 GB/s. [...] For connectivity, the chips will support Wi-Fi 6 (802.11ax) if the laptop manufacturer uses the correct interface module, but the support for Wi-Fi 6 is in the chip. The processor also supports native Thunderbolt 3 over USB Type-C, marking the first Intel chip with native TB3 support.

Wi-Fi Alliance Announces Wi-Fi 6E Moniker for 802.11ax in the 6 GHz Spectrum

The FCC has been considering the opening up of the 6 GHz band (essentially, the 1.2 GHz unlicensed spectrum span just above the currently used 5 GHz band) for unlicensed operation. Wideband unlicensed channels of 160 MHz and more may become essential to achieve expected performance from 802.11ax, 802.11be, 4G LTE, and 5G NR in unlicensed spectrum. Opening up a continuous 1200 MHz chunk will enable substantial amount of new bandwidth over multiple wide bandwidth channels.

Unfortunately, even though there are no currently unlicensed users of the 6 GHz band, certain fixed wireless point-to-point long-range deployments are licensed to utilize it. Wi-Fi platform vendors such as Qualcomm and Broadcom have been confident of working with those users to prevent any interference. Their key message to the licensed incumbents is that any Wi-Fi deployment in the 6 GHz band would use LPI (low-power indoor) operation and can also implement AFC (automated frequency coordination). LPI operation, for example, may impose restrictions on the total EIRP (effective isotropically radiated power) and PSD (power spectral density) for Wi-Fi devices. This will prevent interference due to low power levels and substantial building losses. In addition, most licensed users of the spectrum have their point-to-point endpoints well above the ground (mounted atop towers and buildings), and devices rated for LPI operation are not likely to affect them. AFC involves the maintenance of a database where licensed users are tracked based on their deployment location, and any unlicensed Wi-Fi usage in that spectrum capable of interfering with the licensed users could automatically shift to a different channel.

The Wi-Fi Alliance is introducing a new terminology to distinguish upcoming Wi-Fi 6 devices that are capable of 6 GHz operation - Wi-Fi 6E. This is essentially the benefits of Wi-Fi 6 / 802.11ax (higher performance in terms of faster data rates as well as lower latency) in the 6 GHz band. Wi-Fi 6E devices are expected to make it to the market relatively quickly after regulatory approval, as it only requires changing the antenna tuning / RF front end on existing devices.

802.11be is likely to become Wi-Fi 7 and also operate in the 2.4 GHz, 5 GHz, and 6 GHz bands.

In retrospect, the new Wi-Fi naming scheme is not that bad. Or at least, it's not as bad as USB yet.
