(PhysOrg.com) -- A world-wide expert on wireless communications, Professor Jri Lee of the National Taiwan University (NTU) and UCLA PhD conferred has created a system on a chip (SOC) with transmission speeds 100 times faster than WiFi and 350 times faster than 3.5G cell phones. Professor Jri Lee's team broke the speed record with the SoC design which is about 1/10th the size and cost of existing chips. Preliminary figures indicate the SoC chip can be massed-produced for less than $1 per unit.

A demonstration of Professor Lee´s SoC chip was conducted recently at NTU. The system on a chip combines Front-End Circuits and an antenna array to reach the ultimate transmission speed. In practice the SoC chip can download a 4-GB video in about 10 seconds. The same video would take up to 2-hours using WiFi, 1.5-hours using ADSL and 4.5-hours using Bluetooth to complete the download.

According to Professor Lee, as reported by Taiwan News, the new chip can be used to connect to all domestic audio-visual components like television, stereo, video recorder and transmit to TV screens anywhere in the home instantaneously. In airports and train stations, the SOC could download an entire movie to a cell phone in a couple of seconds and upload thousands of pictures from a digital camera to a computer in a blink of the eye.

Professor Jri Lee´s team at the National Taiwan University Graduate Institute of Electrical Engineering introduction of the SoC chip edges out U.C. Berkeley and IBM´s researchers who are working on a similar solution. The SoC can be used by cell phones and digital cameras as long as the corresponding hardware is developed.

NTU and Professor Lee´s team is in the process of applying for a patent. Professor Lee´s academic career began at NTU. He achieved a combined Master´s degree and PhD in electrical engineering from the University of California, Los Angeles in 2003. His work experience includes Cognet Microsystems in Los Angeles and Intel Corporation where his work included the SONET OC-192 and OC-48 transceivers. Since 2004, he has been Assistant Professor of electrical engineering at NTU and serves on various committees pertaining to broadband data communication, solid state circuits and other interest areas.

so what is the range? Is this is more of a device to device connection rather than a replacement for the cellular data network? What frequencies does it operate on?

this article talks about "transmission speeds." your concern is about the network which is just the carrier. depending on the bandwidth of the network, the transmission speed can either be fully utilized or restricted. imagine comparing wifi and bluetooth. both use radio to network, but different transmission speeds because of the hardware. each transceiver hardware has its own protocol. no bluetooth to wifi. This one will have to be incorporated in existing thingies that require some form of data transmission. It only mentioned static data transmission (i.e. download 4GB movie) but it could also include streaming (e.g. live conference at HD - woooo!).
This is genuine progress on transceiver speeds, not to mention cost - 1/10th.

Numbers numbers numbers... what is the transmission frequency? Power? Range? If it's point to point line of sight and blocked by a Human body then its going to be of limited use.

Nice speed, but I doubt there is a HDD or SSD on the market that can accept 4GB-s in 10 secs.

You can fit 4GB in RAM easily these days ;)
And yes, there are solutions that will have a sufficient speed for that... but your point is valid when talking about normal consumer products. Even the SATA II protocol won't quite cut it, but a couple of expensive SSDs (or four cheap MLC ones) in RAID on two separate SATA controllers or a controller on more than 1x PCI-express lane can do it just fine.

Let me cut this article down to its essential elements:

1. Professor Jri Lee has made a wireless chip.
2. Runs at 3.2 Gb/s
3. 1/10th the size and cost of existing chips
4. can be massed-produced for less than $1 per unit

This is the sum total of the information about this new chip. No information about power usage, operating frequency, range, transmission protocol, or anything else was given.

We have not been enlightened in any way as to how this result was arrived at.

I am sick and tired of reading these kinds of articles - its tells us exactly nothing. Its just a massive regurgitation of scientists press releases.

Ahh - heres the original press release:

%u3000Imagines in the world - living room's television which, the sound the following information speeds along, to absorb record and send out seeing and hearing equipment and so on motion picture projector by the high speed wireless network to link, immediately superelevation picture nature non-compression video and music program, in instantaneous transmission proficient courtyard various corners; In the airport and the station, has momentarily to be possible to download the movie and game's small alcove, spends several seconds times to be possible to download several Giga Byte Gao Hua the nature movie, kills the long lonely time for the passenger; Cannot with any electric cable line, you be possible several camera's in several thousand pictures, a twinkling to upload the computer, shares with the friend; In the office, the use high speed wireless transmission network, %u524E a that figure does decides each kind of file%u2026

%u3000 This kind moves unimpeded high speed the information time was already just round the corner, the transmission speed may reach WiFi 100 times, 3.5G handset's 350 times, the total power dissipation lowers to below same type chip system's 1/40, the chip area may reduce to 1/10, the cost possibly lowers to the traditional communication mold train dozens of below 1, market potential infinite.

%u3000 University of Taiwan Electron Research institute Professor Li Zhi resolute on November 3 holds the remarkable research results publication meeting in the Taiwan University, the publication newest research and development achievement - supervelocity wireless communication system chip (System on a Chip, SOC), will attend this reporter to have University of Taiwan Principal Li Sicen, Assistant Director Chen is dignified, researches and develops long Chen Liangji, electricity capital Dean Bei Suzhang, electronic Manager Bachelor Lu and so on, simultaneously, the association will send technical deputy general manager Dr. Lu Guohong also on invitation to attend.

%u3000 Front end this supervelocity wireless communication system chip success conformity radio frequency the electric circuit, the base frequency modulating circuit, as well as the antenna group, uses the 60GHz frequency band the high bandwidth, achieves highest 5Gb/s the transmission speed, speaking of Gao Huazhi the video and music standard (HDMI) 1.5Gb/s transmission has more than enough to spare. Has not come home the seeing and hearing equipment, hopes by the supervelocity wireless network union again same place, both has avoided the signal line which intertwines disorderly, and may enjoy the superb quality the video and music service.

%u3000Professor Li Zhi resolute the team researches and develops the short distance, low power, the high transmission's 60GHz communication system chip, uses the present 90 nanometer system regulation, has succeeded will possess the electric circuit conformity in the chip, its biggest breakthrough lies in the use has improved the accent changes the way, reduces the power dissipation as well as the electric circuit order of complexity largely, also needs the chip the area to reduce to approximately 1/10.

%u3000 In addition, its unprecedented monocrystal chip and antenna's conformity technology, lets the electric circuit cost fall lowly. It is estimated that this accumulates body's transmission receiver completely, the cost may control about 1 US dollar, compares the traditional combined type the communication mold train (divisor ten US dollars) to have the enormous market superiority. In addition, in future application, the low power loss's consideration will be quite also important, because of many portable installments, like the handset and several cameras and so on, will need to reduce the power loss as far as possible. At present the total power dissipation has been able to control below 300mW, is the present known same type chip system 1/40.

%u3000 Li Jiaoshou pointed out that 60GHz is one international general does not need the license the commercial wave band, as a result of the present use's low-frequency band bandwidth is too small, and extremely crowded, a millimeter-wave band becomes the next generation wide band communication application the only choice. This young electronic professor also pointed out that because 60GHz has by the atmospheric in oxygen absorption characteristic, the transmission process will not disturb the distant place the communication, will therefore suit the short distance high speed application.

%u3000 Because its potential is just infinite, the world each main research and development unit and the technical company, like US's Berkeley University, IBM, Japan's NEC, Fujitsu and so on, none who does not leans develops with all one's strength. Only in the present literature's related paper, were still many by the partial sub-area development primarily, few has the conformability high end product to appear, the reason lies in the 60GHz wave band is the present handset frequency of use (GSM, 1.8GHz) above 30 times, both's speed is similar to the high-valence iron is ordinary with the bicycle, has the enormous difference, but electric circuit's design also difficult many.

%u3000 Li Jiaoshou also stressed that demonstrates the prototype on the conference site is only the most basic embryonic form, in the future will use the transmission benefit higher array antennas, under the similar low power consumption's pattern, may reach a meter above transmitting range. But because this system chip already very complete, the electric circuit simple resistance miscellaneous news ability relative enhancement, very suitable to carry on the practical application the conformity.

%u3000This high speed system chip is the resolute team applies the research results which for University of Taiwan electron institute Li Zhi several years accumulate, and has published in the apex level international periodical, particularly %u201Cthe 75GHz phase-locked loop chip%u201D this paper, in 2007 and in 2008, two years obtains %u201Cthe international solid-state circuit congress%u201D continuously the (ISSCC) big prize (%u201D best edition%u201D and %u201Cbest paper%u201D prize). ISSCC is equal in the international electron research area the Olympic Games, every year has several hundred publishes from global various schools and the industrial field outstanding paper; This paper was only once Taiwan paper which won a prize in ISSCC, was also in the ISSCC history, awarded two big prizes only the papers. This also expressed that Taiwan electron domain's research and development achievement has shown disdain for the whole world; Its research and development team will continue the communication system to make the improvement regarding this in the future, achieves the higher communication potency, and the time soon the practical application, promotes the more convenient comfortable daily life science and technology.

Besides the almost constant flow of political propaganda this site has, It also suffers from a severe case of press-release-ism (fluffy say-nothing articles with the sole purpose of obtaining investors). For example, this article fails to address a single factor of the many factors that define the ~practical~ performance of a wifi chip. Its a common gimmick to employ certain techniques to get performance and then conveniently neglect to tell your investors the profound disadvantages of using those techniques. Like...

1. Frequency range: anything above approx 10GHz won't go through walls, even sheet rock walls, and the higher the freq the worse it gets. That's one of the main reasons those bands are so unused!

2. How many simultaneous channels are there in the service area? For all we know the chip allows no simultaneous channelization, which means pure time sharing would have to be done efficiently (which is HARD to accomplish practically, mainly because of handshaking overhead and unit supervision).

3. If its UWB (ultra-wideband) then its true it will perform far better. UWB is a fantastic technology, practically yielding upwards of 1000-fold improvement in service area channel capacity, but its true there is a ~slight~ interference with pervading narrow band links, and also regulatory agencies still don't allow UWB except with extremely low power.
