Intel Demos 7Gpbs Wireless Docking 52
Lucas123 writes "Intel for the first time demonstrated the Wireless Gigabit (WiGig) docking specification using an Ultrabook, which was able to achieve 7Gbps performance, ten times the fastest Wi-Fi networks based on the IEEE 802.11n standard. The WiGig medium access control (MAC) and physical (PHY) control specification operates in the unlicensed 60GHz frequency band, which has more spectrum available than the 2.4GHz and 5GHz bands used by existing Wi-Fi products. According to Ali Sadri, chairman of the WiGig Alliance, the specification also supports wireless implementations of HDMI and DisplayPort interfaces, as well as the High-Bandwidth Digital Content Protection (HDCP) scheme used to protect digital content transmitted over those interfaces. It scales to allow transmission of both compressed and uncompressed video."

I know better, and the AC you responded to is correct. 802.11n works just fine with Windows XP and 7. I would love it to work well with Linux too as I use several Linux machines including a laptop that would benefit from the higher bandwidth. They just haven't quite gotten the bugs out of the system yet.
It works great with OS X machines too. Are you still going to imply it isn't a Linux problem?

Which explains why all of my 802.11n devices have to be set to 802.11g, in order to even connect to the wireless-N router, under both XP and 7.....

Wireless is a clusterf*ck in general. It's something that sounds like a cool idea but has a lot of technical hurdles. Its kind of fine if you have no other choice but sucks when compared to the alternatives.

That sounds like a personal problem, and I'll counter your anecdotal evidence with the fact that my own 802.11n works just fine with my Windows machines at home as well as my Macs. My linux boxes are wired except for the laptop and that's a bit older so only supports G. I have no first hand experience with Linux not working with N but this thread is not the first time I've heard such complaints.

You know, HDCP could actually have a use here if the display data are not otherwise encrypted. I don't know how well it would actually protect against eavesdroppers. At the very least it would remove any repeating patterns which eavesdroppers could use for statistical analysis.
It would be silly if it wasn't encrypted, but there are often some flaws in new standards like this one. (I assume it's easier to eavesdrop on a 60 GHz signal than on actual wires, but there may not be that huge a difference.)

That's because no reasonable person expects there to be any effects. Wifi signal power is ridiculously low compared to many other applications of electromagnetic waves. Your microwave oven is allowed to leak more power than your wifi router is allowed to emit.

Some basic background (Score:5, Informative)
For those wondering who are too lazy to Google, 60 GHz is right in the middle of the resonance range of the oxygen molecule (O2), so it's attenuated by nothing but air. That limits its range to just a few kilometers at reasonable (read, unlicensed) power levels.
Of more practical interest, 60 GHz won't go through anything more solid than cloth. In particular interior walls block it. So this a in-the-same-room technology, and without some very fancy processing of multi-path bounce signals, it's basically a line of sight technology. In other words, a 60 GHz transmitter attached to your tower under your desk is going to have a hard time driving a monitor sitting on top of your desk. That's why the article waxes lyrical about laptops, which are usually set on top of the desk. Sadly, we're likely to be stuck with video cable for many years to come.
Of course silicon is dirt cheap (sand cheap?) these days, so possibly chips can be designed that can do that processing. I don't know what the latencies might be like though. It might be intolerable for controlling a mouse. You'd have to ask a radio guy.
Re: (Score:1)
Put a little receiver/transmitter on top of the table and connect it with a cable to the computer. Or make it go around the edge of the table and connect using this technology in both directions. Yes, latency could be a problem, but I suspect that this link wouldn't have to add much latency compared to the latency that could be removed from optimizing other parts of the chain from input to screen output for lower latency.

I wasn't referring to mouse movement data being transmitted at 60 GHz. I was referring to the cursor showing up on the screen over a wireless connection. Latency of the 60 GHz connection matters there. Exceed some minimum threshold and your cursor will appear to lag behind the mouse, an intolerable circumstance.

I don't understand the distinction. You seem to be talking about transmission latency (including error correction), which is transmission latency, regardless of whether it's distance created, or horribly designed power savings.
Wireless works fine for me for the crowded and interference-prone 2.4 GHz. If you've ever use wireless mice extensively, you'd have noticed that power savings on optical mice kills performance (delay, lag, etc.) any more than any wireless delay could.

Wireless doesn't work fine for me in the crowded and interference-prone 2.4 GHz band. That was one of my points. My laptop, with its rather poor radio, can see as many as 14 different access points, and the number of timeouts and connection drops it experiences with my own access point in consequence is astronomical. Streaming video is completely out of the question and even Windows filesharing is intolerably bad. Simply receiving a directory list can take upwards of 30 seconds, with all of the timeouts

Say a projector setup in a meeting room. Wiring a 20+' heavy gauge VGA cable in say an existing meeting room isn't just plug and play (unless you're going half pass and running it on the floor or taped to a wall rather than in the wall and ceiling).
That'd be a perfect setup for this (and yes, these rooms are used for more just power point slides)

Any commercial wiring installation should be a little more flexible and more robust than your average cut-rate tract home. Plus you have the likelihood that a corporation isn't quite as cheap as a consumer. That's why companies have wired interfaces already.

I don't either, but this mania for portable devices and the proliferation of walled garden software distribution meaning vendors are pushing for more appliance-like behavior rather than desktop behavior means the specter of a display with no physical connectors at all becomes an actual possibility in the next decade. In truth, that's exactly the sort of thing Apple is even likely to do, purely in the interest of aesthetics (plus they care damn all about backwards compatibility and product lifespans).
