Tri-band Wireless Products on the Horizon
Just bought a brand-spankin’ new dual-band router? Don’t pat yourself on the back too hard, Binky; your new toy just might be outclassed as soon as the end of this year by the first generation of tri-band devices with wireless radios operating on the 2.4-, 5.0-, and 60GHz frequencies. These could be the first networking products capable of moving bits around your house at supremely fast speeds and cooking a pizza at the same time.
We’re just kidding about the pizza, but wireless routers operating on the unlicensed 60GHz frequency band do promise to deliver data throughput as high as 7Gb/sec. The IEEE Task Group AD (TGad for short; not to be confused with “teabag”) is busy developing a standard—IEEE 802.11ad—but the companies hoping to sell actual products based on this new technology aren’t taking any chances that the famously methodical international standards body might take the same long winding and road they did with 802.11n. They formed a trade group—the Wireless Gigabit Alliance (WiGig)— in May 2009, and the alliance announced its own first-draft standard today.
“WiGig will be submitting proposals to TGad,” said Mark Grodzinsky, Marketing Work Group Chair of WiGig Alliance and VP of Marketing at Wilocity. “But this alliance is a direct path to market if the IEEE turns out to be a dead end.” The WiGig Alliance’s specification envisions a host of tri-band products, including consumer electronics hardware, displays, battery-operated handheld devices, and home networking equipment that will remain compatible with existing Wi-Fi products.
WiGig moved to further grease the skids by forging a partnership with the Wi-Fi Alliance, the trade group currently responsible for certifying wireless products as being in compliance with IEEE 802.11 standards. “This is a shorter-range technology that has a lot of bandwidth,” added WiGig Alliance board member and Dell executive Bruce Montag. “It’s designed to complement Wi-Fi, not replace it.”
This WiGig/Wi-Fi partnership could kill the existing standard, WirelessHD, even though that technology is available at retail today in wireless HDMI streamers from Gefen and Best Buy. “One guy will run ahead of the pack by doing one thing really well” said Grodzinsky, “but his product will only serve this limited market. Our alliance will get the industry together in a very methodical way. As an industry body, we have a spec that works, and we’re working on developing a certification process, so we can get the stamp of interoperability.”
WiGig Alliance members include all the heavy hitters in tech—Intel, AMD, Atheros, Microsoft, Broadcom, Nvidia, Marvell, and Realtek—and the alliance announced today that Cisco was joining its board of directors. Its roster also boasts a strong lineup of consumer electronics manufacturers, including Panasonic, Toshiba, Nokia, and Harman. Publication of the WiGig spec means that member companies can begin developing 60GHz wireless products now, without the need to pay royalties or licensing fees. The alliance expects to see the first retail products by Q4 2010 or early in 2011.

I'll stick to the wire. I don't like broadcasting to the neiborhood.

You can hide SSID from being visibly broadcasted, provided you use WPA/WPA2 with a strong password. Of course, it won't stop a determined hacker from discovering your hidden SSID except getting in, but it is enough to deter your casual neighbors from scanning your network.

I'd like to know what they plan on doing about the current inefficiencies of Wireless communication.
Currently, roughly half the bandwidth of a wireless LAN is immediately soaked up by packet meta-data, encryption information, routing information, etc, can currently consume 50% of an average wireless packet.
Second, as far as I'm aware current wireless technologies only provide an even division of bandwidth for each client, if you have 10 PC's then each PC gets alloted 1/10th the available bandwidth.
If you've ever wondered why a wireless LAN transfer can be as low as 2MB/s over a wireless N network, those are the biggest, along with inherent issues with wireless signals.
Even 7Gb/s would quickly be reduced to 350Mb/s if the above remains true with a 10 PC LAN.

Well you might want to read up on wireless. Wireless is a half duplex media. So thus that is why you see half the bandwidth.
Also wireless only transmitts one at a time it has to share the media. It has protection mechanisms that help to prevent it. So once you have the media and are transmitting you get the full bandwidth (although it is only half duplex). So your 1/10th is wrong. Now an access point generally will talk only as fast as the dumbest client. Granted the more clients you have the longer it can take to get the all clear to transmitt from the access point. So if you have a b client on a g network it slows everything down to b. Now there are some protection protocols that can let the g transmitt somethings at higher levels, but other things have to be slowed down. Which can also be why a N network will slow down. Also as you get father away from an access point it will start to use dynamic rate selection and lower the bandwidth for the weaker signal.
So if all 10 of your clients are using the new 7 Gbs spec and everything is with in specs you would see around 437Mbs of throughput (if the bandwidth is 7Gbs). But the article states a throughput of 7Gbs so that probably means the bandwidth is around 14Gbs, so you will see 7Gbs.
As for you thinking that overhead takes up 50% will your just wrong. Certain encryption methods can take up some but it's no where near 50%.

I'd love nothing more than the capacity to wireless everything in the home. I wish them well. My only concerns are neighbor overlap, interference, and security. Also, is there the possibility that the present unlicensed 60GHz frequency could later be licensed causing it's loss?

Well the 60GHz band could be licensed just as easy as the ISM (2.4GHz) or UNII (5 GHz) bands used by wireless now.
