$10, 5Gbps 'GiFi' Chip
Two watts of power over ten meters
by Karl Bode 10:08AM Friday Feb 22 2008
Blowing past other recent advancements in high-speed, short range wireless technologies, Researchers in Melbourne, Australia are working on a $10 chip that can transmit data at 5Gbps over ten meters. Dubbed "GiFi," the chip could be used to quickly allow users to transfer HD films or other massive content between cellphone and PC. The transceiver-on-a-chip uses a tiny one-millimetre-wide antenna and less than two watts of power, using the 60GHz "millimetre wave" spectrum to transmit data.

Cool!

Where does this thing get it's power from though? Otherwise, this would be a very nice enhancement for stuff if it can transmit through walls well as well. And $10 for a chip like this? That's cheap!

I imagine it would use a thin film battery.

The range of this device is very limited... which is actually a good thing for the type of applications it might be used for.

This is really cool, but it costs about $10 to manufacture. They have to recoup costs for research and overhead, so it'll cost much more than that when it comes to market, but if it becomes widespread, the costs will go down dramatically. I like in the article how it mentions a video kiosk can upload a movie in seconds then you can download a movie in seconds when you get home. Even though we are moving to a home delivery via broadband, that would still be a meat idea for many applications.

Re: Cool!

Theres not really consumer storage devices that would be able to keep up with the 5Gbps throughput speeds, let alone even 1Gbps.

Its range is 10 meters or less(about 11 yards or 33 feet). Great for devices in an entertainment center talking to each other or as a replacement for bluetooth between PCs, cell phones, MP3 players, etc.

For moving data around a house, this isn't the technology.

Nah, that one is a lot smaller and shaped like a pin, but smaller. Spying on people will take less throughput than a movie requires.

So how is this different than what SiBeam or any of the other 60 GHz companies are doing?

Isn't Melbourne University the same group that is involved in holding up the 802.11n standard over a patent dispute?

Because pretty soon you'll be able to use a laser projector that is built in your phone to project a much bigger picture than any built in screen.

This article mentions the two dirtiest words in the lexicon of the MPAA, and the RIAA; transfer, and content. They will soon have a joint press release stating pirates will use this chip to remotely suck the content from the video, and CD stores they visit.

Clarification

"Two watts of power over ten meters" implies the device transmits two watts of power. This is incorrect. It uses two watts of power and transmits over 10 meters. That's 2000 mAH and would be a huge drain in devices like cell phones.

These components will enable things like thumb drives to transfer data without being physically connected to the source or destination, which is an interesting application. It's also after the "wireless" (literally) home theater installation where everything is connected via short-haul radio signals. Mostly, it's a replacement in Bluetooth-type applications.

How did you get to the 2000mAh value??? Fuzzy math???

Let's see now...most of these devices run at 1-3 volts and two watts would require 2000 mAh at one volt for one hour. If you wish, we can assume three volts and a little less than 700 milliamp-hours. Either way it's a huge power drain in a battery-operated device, which is usually expected to run far longer than an hour on charge.

I was thinking the same thing. This device will absolutely kill the battery of any cell phone its used in. Running AIM on your Blackberry alone will cut your battery life in half, I can only imagine what this chip would do! Still not a bad idea, but probably meant more for home appliances and PC's that have robust batteries or power supplies.

Re: Clarification

It's a great technology for avoiding connecting cables between AC-Powered devices or those which only see occasional use like thumb drive-type portable storage, but putting this in a cell phone as the linked article suggests is absurd.

Plus, at 60 GHz, I don't think it'll play well with solid objects.

Lets also keep in mind that that may be the maximum power consumption for that transfer rate. No phone processor can handle data rates of 5Gbps let alone PCs. I also don't think you're phone would need to go through with the full 10 meters. That's a LONG distance for transferring something from your phone to a device at your house or work place.

Instead, this is probably for enabling of wireless HDMI or the like at full bandwidth. For a phone though or other mobile device as far as power goes you're looking at shorter ranges and less bandwidth requirements. Because of that power consumption can probably fall within the range of Bluetooth or WiFi at a much higher data rate.

Note too that that data rate more than likely reflects raw bits per second through the transceiver and doesn't take into consideration any protocol overhead including things like error checking, headers, etc..

actually you don't have to go that far in terms of mAH, plus you make an assumption on what voltages are used. i'd just look at how many joules the battery stores. my guess most cell phone batteries store less than 10 joules (mine only stores ~3.5 joules). just comparing 3.5 joules to 2 watts of consumption give ~1.75 seconds of usages assuming no losses anywhere and everything is ideal.

no matter how you look at it, this chip can only be used to short busrts of time, but at 5gbps, a very small amount of time translates into a large amount of data.

lazy? or worthless?

"to quickly allow users to transfer HD films or other massive content between cellphone and PC. "

Too bad it will only be useful in a new generation of suitcase phones, to have enough battery and 50 gig's of flash memory.

Hmm

I can see many MP3 players, and phones in the future using this chip.

Would be a great way to connect my MP3 player to the PC. Would be faster than USB as well.

how bout i 1 up ya there, and say it can be used as a local(really local) area use age as external media drives, using the SATA interface as it's connection and sending over the wireless device.

think about it, instead of running a USB cable to your external drive, you just hook the wireless adapter to the PC through an internal(or external) sata port and it adds drives to the system without actually physically inserting them

Picture misleading

I looked at the picture before looking at the title of this thread and wondered why there was a discussion of what looked like a booger.

Other than that, it's cool tech. Whether it can be used for its intended purposes without drawing a lawsuit from the mafIAA is something to be seen.
