[ZDNet] Forget Intel's Thunderbolt, Wireless USB is the game-changer

post #1 of 48
Thread Starter

Last week Intel made a big deal about the official launch of its Light Peak technology — now called Thunderbolt — which enables much faster data transfers (10Gbps) and the ability to consolidate accessories and video connections into one cable with a connector that is half the size of a USB plug.

While those are useful features, the arrival of Thunderbolt had me scratching my head and asking two big questions:

1. What happened to USB 3.0?
2. Where’s Wireless USB?

Both of those technologies have been in development for years, but somehow Light Peak/Thunderbolt was able to leapfrog them, at least in terms of getting the green light from Intel and its partners.

I just thought I'd share this, something I need to read up on myself...

Obviously Wifi is not going to give you anywhere near what a cable can yet, but they are working really hard on the radio wave department presently...

0.48 vs 100 gbps

yeah, i think thats pretty damn obvious what is better there.

Because your mouse and keyboard totally saturate 100gb/s...

If my wireless network isn't good enough for lag-free gaming, it isn't good enough for transferring large files wirelessly.

Well, I think what the author is trying to say is, if they would have put more into WIFI, rather than wired networking, they would have taken a better route...

Obviously Intel gave up going 100% Wifi, and I have to say, being the consumer who has been waiting and waiting for some results, I'm damn glad they did something!

So it's settled Wifi will never be all that? Is it official?

802.x has been developing on its own regardless of Intel's support. There's no reason to hold back LightPeak just because you don't have fast enough WiFi. They can both be developed along side each other. Replacing all other ports with a universal LightPeak port is awesome for consumers. You only need one cable for all devices.

White space WiFi will be here soon offering 800mbit+ speeds. We just have to wait for the licensing to finalize. There's been news posted about it here before.

Its funny how many people I see saying "Buy the new Mac, it has thunderbolt."
Then they regurgitate the press release about offering 10GB transfer speeds etc.

I still wonder what happened to USB3. Its been out for months and has yet to be really adopted as more than a gimmick but thunderbolt has been out for 2 days and its the biggest revolution in computing history apparently.

Until Thunderbolt is supported widely, im not touching it. Intel and Apple alone is not enough to make me confident the technology will develop past where it is now.

Interesting article though.

USB has too much latency, too much overhead and is too slow; nor does it support existing mini-display ports which high bandwidth devices are already using. USB 3.0 is kind of like Zip drives: an improvement on a dying technology that is being replaced with something better anyways.

USB has issues, but the latency and speed issues are a moot point, since most USB devices do not require these. USB is entirely fast enough for mice and keyboards (even USB 1 was entirely fast enough), while keychains and SD cards are inherently "slow" and don't even challenge USB 2 speeds.

USB is perhaps slow when it comes to external hard drives - but people that really need speed for those devices will use better solutions, like FireWire, eSATA or NAS. USB is entirely fast enough for printers and scanners.

Wireless USB will be a better solution for printers than WiFi - since WiFi is a network topology that is not well suited for bit streamed devices (since networks are block oriented devices).

USB 3 has only been hindered because Intel has favoured Light Peak because it is proprietary, and they can attempt to monopolize it with onerous licensing agreements, while USB 3 is more of an open ended technology that all manufacturers can offer.

I don't think USB is dying, there is no evidence of that, since it will remain the standard that all manufacturers will offer. Thunderbolt or Light Peak - it is specious because I think few manufacturers will jump on it. Like, if manufacturers stayed away from FireWire because the chipset was $1.50 more than USB - they will not accept Thunderbolt if it is more expensive to implement.

I do not see any advantage in connecting video monitors through the port. Video is high bandwidth, so the people that complain about high speed USB having high latency, will surely reject the outrageous latency on Thunderbolt once they are passing great wads of video at high frame rates. I think Intel is aiming towards that in order to squeeze out widely adopted standards like VGA and HDMI, so they can score profits on selling their proprietary chipsets.

Besides, Thunderbolt is no Light Peak, since there is no fiber optic involved - and I think the cost of it will be a deal killer in a price sensitive marketplace, especially when there are zero devices that use it, and it remains unsupported on the vast majority of computers that run Windows or some variant of *Nix.

I believe Thunderbolt is proprietary as much as USB is....

Thunderbolt optical are due out in the next year and should be backwards compatible with electrical versions.
