Those annoying sync cables?
You mean the ones that provide power to the other device?
It's now more than two years since the Wireless Gigabit Alliance (WGA) released the first full version of its 7Gb/s would-be next-gen Wi-Fi technology. There's been some activity in the intervening 26 months, including the first big multi-vendor interoperability test, but the second of these "plugfests" has only now taken place …
Or the ones that mean I have to sit cross-legged in front of my TV if I want to share my desktop from the laptop. Or make sure that I'm located near a projector in a meeting etc.
Wires are still my preferred network medium due to the relatively poor speed of wireless, but not having to worry about display cables would be a godsend.
...so maybe the ideal home roaming setup will be to have a "base station" in each room where the light fitting would be in the centre of the ceiling and to network these base stations together with wired gigabit (or faster). This would allow very high speed links for devices roaming between rooms and the placement of the base station outside of the general clutter should be good for links - as in when there's no direct link because of a sack of water in the way, it can still bounce off a wall.
Why do I get the feeling the tinfoil headgear brigade are gonna have a(nother) feeding frenzy? Tumors... Mind control... Zombie apocalypse?
Personally, and you can call me old fashioned if you wish, I *like* cables, big fat masonry drills and knowing a mate with his or her laptop can just sit down, plug in and be sorted in mere seconds. Wireless certainly has its place, and WiGig will be a very handy tech to have in the networking arsenal, but I do not see it as preferable as far as my home is concerned.
/me braces for a volley of "-1 Luddite".
I felt the same up to a couple of years ago. Now though, wireless is reasonably hassle free. My home network is named reasonably sensibly and the password, whilst a bit long, is simple to communicate and type in.
That being said, all my fixed devices are cabled and I can't see that changing any time soon.

Dunno .. apparently, with sufficiently sensitive antennas, and enough power you can extend the range of wifi into 100s of meters, maybe even kilometers.
As long as your receiver is sensitve enough to pick up the signal from the ambient noise, and your sender is powerful enough.
it's a bit like people saying they dont need to put a password or encryption on their home wifi setup, because it has too limited a reach. It might have too limited a reach for their laptops, but a bit of custom sending and receiving gear will prove them wrong.
So all it needs is a hacker with a bit of a mcgyver skill
When ever wireless technology tries to replace a wire it will fail. If however it is there to make connecting up easier when we move about it will be successful. How many desktop machines have Wi-Fi? Not a lot, you can pay $3500 and get the number if you like from iSuppli. It has taken over 12 years for the 5GHz band to start to be used, it is called 80211a after all and now we are now discussing 802.11ad. Don't hold your breath waiting to buy a Wi-Gig dongle pair for less than $200.

hate wireless
I started out with wireless all over my home a few years ago which was great but I've slowly noticed an increase in the number of networks within range of mine and ever decreasing performance of my own. I've now wired the house instead for the bulk of devices and its pretty much only visitors that use the wireless and occasionally my kids on their net books.
On another note I think most of the sales staff that try to sell you wireless equipment should be given a slap, I recently saw a young probably commissioned based sales idiot flogging an old couple wireless N because its faster, no mention of the fact that they would still be limited by internet speed, would need wireless N adapters or compatible hardware etc etc. I'll give you a hint which shop...... Begins with a P, its got a C in it and World and they screwed that couple out of nearly £150
Once again it seems that they have completely missed the boat.
Why is nobody looking at distributed wireless networking?
Every wireless device will become a local router so if your tablet moved out of range, if would send it's packets to the TV which would forward them to the Satellite receiver which is cabled to the ISPs router.
Yes, it adds latency so not ideal for gaming but if latency matters to you then plug the games console in.
For most other net uses it would be ideal and could give decent coverage to most households.
You could even buy plug into the mains/light socket devices that would act as fixed routers.
Even 802.11n is pointless, does your client support all the features your access point claims, multiple streams?, no, very unlikely if your using a phone or tablet or any other built in wireless. Speeds of 300mb @ 2.4 and 450 @ 5ghz, lies unless your client is physically built like the access point with multiple aerials etc. Check the speed you get on your phone or tablet, 65mbps or 72mbps at best. John.w said it best, wireless is about mobility not replacing a high speed cable. Wireless is about wandering into an area, browsing email, web, semi low bandwidth youtube videos.
2.4ghz is dead, 802.11n / channel bonding is unusable with it being everywhere. Client adapters need to embrace 5ghz and multiple streams faster. 5ghz allows the channels and throughput.
Dont forget that wireless is a shared medium, its still a HUB, with each additional client the speed is cut in half again for every client.
Alcatel-Lucent Enterprise is the latest networking outfit to add Wi-Fi 6E capability to its hardware, opening up access to the less congested 6GHz spectrum for business users.
The France-based company just revealed the OmniAccess Stellar 14xx series of wireless access points, which are set for availability from this September. Alcatel-Lucent Enterprise said its first Wi-Fi 6E device will be a high-end "premium" Access Point and will be followed by a mid-range product by the end of the year.
Wi-Fi 6E is compatible with the Wi-Fi 6 standard, but adds the ability to use channels in the 6GHz portion of the spectrum, a feature that will be built into the upcoming Wi-Fi 7 standard from the start. This enables users to reduce network contention, or so the argument goes, as the 6GHz portion of the spectrum is less congested with other traffic than the existing 2.4GHz and 5GHz frequencies used for Wi-Fi access.
Wi-Fi 6 and 6E are being promoted as technologies for enabling industrial automation and the Industrial Internet of Things (IIoT) thanks to features that provide more reliable communications and reduced costs compared with wired network alternatives, at least according to the Wireless Broadband Alliance (WBA).
The WBA’s Wi-Fi 6/6E for IIoT working group, led by Cisco, Deutsche Telekom, and Intel, has pulled together ideas on the future of networked devices in factories and written it all up in a “Wi-Fi 6/6E for Industrial IoT: Enabling Wi-Fi Determinism in an IoT World” manifesto.
The detailed whitepaper makes the case that wireless communications has become the preferred way to network sensors as part of IIoT deployments because it's faster and cheaper than fiber or copper infrastructure. The alliance is a collection of technology companies and service providers that work together on developing standards, coming up with certifications and guidelines, advocating for stuff that they want, and so on.
The Wireless LAN market was battered by a choppy supply chain in the first quarter of 2022 and lockdowns in China are compounding the problem, according to analysis by Dell'Oro Group.
Many organizations have scheduled network upgrades, but supply is not able to keep pace with demand and backlogs are reportedly 10 to 15 times greater than they were pre-pandemic.
Several manufacturers have cited components from second and third-tier suppliers as the cause of the bottleneck, Dell'Oro said, which means that the problem may not be a shortage of Wi-Fi silicon, but rather of secondary components that are nevertheless necessary to make a complete product.
New York City this week ripped out its last municipally-owned payphones from Times Square to make room for Wi-Fi kiosks from city infrastructure project LinkNYC.
"NYC's last free-standing payphones were removed today; they'll be replaced with a Link, boosting accessibility and connectivity across the city," LinkNYC said via Twitter.
Manhattan Borough President Mark Levine said, "Truly the end of an era but also, hopefully, the start of a new one with more equity in technology access!"
AMD and Qualcomm have rolled out a joint effort that brings remote management capabilities over Wi-Fi for AMD business systems, potentially boosting their appeal for corporate IT departments.
The two companies said they were working together to improve Qualcomm's FastConnect wireless kit for AMD compute platforms based on the Ryzen chips for desktops and laptops. The starting point for this is AMD Ryzen-powered business laptops using Qualcomm's FastConnect 6900 system that delivers Wi-Fi 6 and 6E plus Bluetooth 5.3, supporting Wi-Fi connection speeds up to 3.6Gbps.
Remote management is enabled by the combination of the AMD Manageability Processor now embedded in Ryzen PRO 6000 systems and the FastConnect 6900 system, AMD and Qualcomm said, with support for the DASH client management standard developed by the Distributed Management Task Force (DMTF).
Qualcomm is sampling its Wi-Fi 7 Networking Pro Series chips aimed at throughput of more than 10Gbps for enterprise access points, gateways, and premium home routers.
The third generation of the chipmaker's Networking Pro Series platforms is set to "initiate a new era" of 10Gbps Wi-Fi, Qualcomm claimed, stating that the new portfolio is optimized for multi-user environments and low CPU utilization to power collaboration, telepresence, and metaverse applications for both home and enterprise environments.
Sampling means that the Networking Pro silicon is available to Qualcomm's OEM customers so they can develop and test the Wi-Fi 7 products that will ship to end users at some point. It isn't clear when buyers will actually be able to get their hands on kit to deploy, although Qualcomm previously said it expects to see Wi-Fi 7 products hit the market in 2023.
Businesses shouldn't wait for Wi-Fi 7 networking kit when Wi-Fi 6E can give them significant advantages today.
So says the Wi-Fi Alliance, which disputes the message coming from parts of the industry that Wi-Fi 6E will only see limited adoption because of supply chain issues that might cause buyers to hold off until Wi-Fi 7 is available. Some netizens and organizations have lately complained it can take six months, a year, or more for Wi-Fi 6E equipment they ordered to arrive.
Wi-Fi 6E builds on Wi-Fi 6, which was finalized as the 802.11ax standard in 2019, saw early products in 2020, and started to be widely adopted in 2021. Wi-Fi 6E is essentially the same, but adds the ability to use frequencies in the 6GHz portion of the wireless spectrum as well as the existing 2.4GHz and 5GHz bands. It follows moves by regulators in the US and elsewhere to open up the 6GHz spectrum for Wi-Fi use.
The Wireless Broadband Alliance (WBA) has completed testing to prepare for the deployment of WBA OpenRoaming, a federation service built to give seamless access to Wi-Fi hotspots across Europe's municipal networks.
WBA OpenRoaming, described as a "Wi-Fi roaming standard," is intended to provide users with roaming access to Wi-Fi hotspots without having to keep registering with different operators or enter login credentials every time.
The WBA also claims that OpenRoaming offers enterprise-level security and protects user privacy while complying with European GDPR policies when roaming between Wi-Fi networks.
Cisco on Tuesday issued a critical security advisory for its Wireless LAN Controller (WLC), used in various Cisco products to manage wireless networks.
A vulnerability in the software's authentication code (bug type CWE-303) could allow an unauthenticated remote attacker to bypass authentication controls and login to the device via its management interface.
"This vulnerability is due to the improper implementation of the password validation algorithm," Cisco's advisory says. "An attacker could exploit this vulnerability by logging in to an affected device with crafted credentials.
Supply chain woes with Wi-Fi 6E products could see organisations miss on deploying network kit with the new standard and instead wait on availability of Wi-Fi 7 equipment expected next year, says Dell'Oro Group.
Wi-Fi 6E builds on Wi-Fi 6, itself only a newish standard, by adding support for frequencies in the 6GHz portion of the spectrum. One advantage of this is that compatible devices can be steered to these frequencies, keeping the existing 2.4GHz and 5GHz bands free for other devices and reducing network contention. Cisco is one firm that has just introduced Wi-Fi 6E access points with this capability.
But according to Dell'Oro, although manufacturers might have launched Wi-Fi 6E devices, such products are often either not available, or they are in very limited supply. There is a general shortage of semiconductor components, not just Wi-Fi semiconductors, owing to the pandemic impacting production in the countries where the chips are manufactured, and this has led device vendors to focus resources on shipping the most popular models.
