GEDC researchers have already achieved wireless data-transfer rates of 15 gigabits per second (Gbps) at a distance of 1 meter, 10 Gbps at 2 meters and 5 Gbps at 5 meters. \n\u003C\/p\u003E\n\u003Cp\u003E\u0022The goal here is to maximize data throughput to make possible a host of new wireless applications for home and office connectivity,\u0022 said Prof. Joy Laskar, GEDC director and lead researcher on the project along with Stephane Pinel.\n\u003C\/p\u003E\n\u003Cp\u003EGEDC\u0027s multi-gigabit wireless research is expected to lend itself to two major types of applications, data and video, said Pinel, a GEDC research scientist. \n\u003C\/p\u003E\n\u003Cp\u003EVery high speed, peer-to-peer data connections could be just around the corner, he believes - available potentially in less than two years. \n\u003C\/p\u003E\n\u003Cp\u003EDevices such as external hard drives, laptop computers, MP-3 players, cell phones, commercial kiosks and others could transfer huge amounts of data in seconds. And data centers could install racks of servers without the customary jumble of wires.\n\u003C\/p\u003E\n\u003Cp\u003E\u0022Our work represents a huge leap in available throughput,\u0022 Pinel said.  \u0022At 10 Gbps, you could download a DVD from a kiosk to your cell phone in five seconds, or you could quickly synchronize two laptops or two iPods.\u0022\n\u003C\/p\u003E\n\u003Cp\u003EThe input-output (I\/O) system of current devices cannot approach such speeds.\n\u003C\/p\u003E\n\u003Cp\u003EMoreover, Pinel said, users of multi-gigabit technology could wirelessly connect to any device that currently uses Firewire or USB.\n\u003C\/p\u003E\n\u003Cp\u003EWireless high-definition video could also be a major application of this technology. Users could keep a DVD player by their side while transmitting wirelessly to a screen 5 or 10 meters away.\n\u003C\/p\u003E\n\u003Cp\u003ECurrently, Pinel said, the biggest challenge is to further increase data rates and decrease the already-low power consumption, with a goal to double current transmission rates by next year. The Georgia Tech team is seeking to preserve backward compatibility with the WiFi standard used in most wireless LANs today.\n\u003C\/p\u003E\n\u003Cp\u003EGEDC researchers are pursuing this goal by modifying the system architecture to increase intelligence and effectiveness in the CMOS RF integrated circuits that transmit the data. The researchers are using advanced computer-aided design tools and testbed equipment to recalibrate system models and achieve the desired improvements in speed and functionality.\n\u003C\/p\u003E\n\u003Cp\u003EInvestigators are placing special emphasis on implementing an RF concept called single-input-single-output (SISO) \/ multiple-input-multiple-output (MIMO), which enables ultra-high data throughput.  At the same time, they seek to preserve backward compatibility with WLAN 802.11, the WiFi standard used in most wireless LANs today.\n\u003C\/p\u003E\n\u003Cp\u003E\u0022We are pursuing a combination of system design and circuit design, employing both analog and digital techniques,\u0022 Pinel said. \u0022It\u0027s definitely a very exciting mixed-signal problem that you have to solve.\u0022 \n\u003C\/p\u003E\n\u003Cp\u003EEven when sitting on a user\u0027s desk, Pinel stresses, a multi-gigabit wireless system would present no health concerns.  For one thing, the transmitted power is extremely low, in the vicinity of 10 milliwatts or less.  For another, the 60 GHz frequency is stopped by human skin and cannot penetrate the body.\n\u003C\/p\u003E\n\u003Cp\u003EThe fact that multi-gigabit transmission is easily stopped enhances its practicality in an office or apartment setting, he adds.  The signals will be blocked by any wall, preventing interference with neighbors\u0027 wireless networks. \n\u003C\/p\u003E\n\u003Cp\u003ECurrently there are no world standards in this bandwidth, explains GEDC Director Laskar. To address the situation, representatives of the ECMA International computer-standards organization met at GEDC in February to discuss a new international 60 GHz standard. The three-day gathering  included representatives from the Electronics and Telecommunications Research Institute of Korea, GEDC, Intel Corp., IBM Corp., Matsushita Electric Industrial Co. Ltd. (Panasonic), Newlans, Philips Semiconductors, Samsung Electronics Co. Ltd and Samsung Electro-Mechanics Co. Ltd. The ECMA International organization will meet again at GEDC in October to finalize the technical decisions.\n\u003C\/p\u003E\n\u003Cp\u003EThe IEEE, the top international association of electrical engineers, is also weighing a 60 GHz standard, to be called 802.15.3C.\n\u003C\/p\u003E\n\u003Cp\u003ELaskar believes that additional applications will emerge as multi-gigabit technology becomes standardized and gains maturity.  \n\u003C\/p\u003E\n\u003Cp\u003E\u0022The promise of multi-gigabit wireless is tremendous,\u0022 he said. \u0022The combination of short-range functionality and enormous bandwidth makes possible a whole range of consumer and business applications that promise great utility.\u0022\n\u003C\/p\u003E\n\u003Cp\u003E\u003Cstrong\u003EResearch News \u0026amp; Publications Office\u003Cbr \/\u003E\nGeorgia Institute of Technology\u003Cbr \/\u003E\n75 Fifth Street, N.W., Suite 100\u003Cbr \/\u003E\nAtlanta, Georgia  30308  USA\u003C\/strong\u003E\n\u003C\/p\u003E\n\u003Cp\u003E\u003Cstrong\u003EMedia Relations Contacts\u003C\/strong\u003E: Rick Robinson (404-694-2284); E-mail: (\u003Ca href=\u0022mailto:rick.robinson@innovate.gatech.edu\u0022\u003Erick.robinson@innovate.gatech.edu\u003C\/a\u003E) or John Toon (404-894-6986); E-mail: (\u003Ca href=\u0022mailto:jtoon@gatech.edu\u0022\u003Ejtoon@gatech.edu\u003C\/a\u003E).\n\u003C\/p\u003E\n\u003Cp\u003E\u003Cstrong\u003EWriter\u003C\/strong\u003E: Rick Robinson\n\u003C\/p\u003E","summary":null,"format":"limited_html"}],"field_subtitle":[{"value":"Work could make wired computers and peripherals obsolete"}],"field_summary":[{"value":"New research at the Georgia Institute of Technology could soon make that tangle of wires under desks and in data centers a thing of the past.","format":"limited_html"}],"field_summary_sentence":[{"value":"Scientists replace tangle of wires for electronics"}],"uid":"27303","created_gmt":"2007-07-19 00:00:00","changed_gmt":"2016-10-08 03:03:29","author":"John Toon","boilerplate_text":"","field_publication":"","field_article_url":"","dateline":{"date":"2007-07-19T00:00:00-04:00","iso_date":"2007-07-19T00:00:00-04:00","tz":"America\/New_York"},"extras":[],"hg_media":{"72009":{"id":"72009","type":"image","title":"Research on high-speed wireless","body":null,"created":"1449177425","gmt_created":"2015-12-03 21:17:05","changed":"1475894649","gmt_changed":"2016-10-08 02:44:09"},"72010":{"id":"72010","type":"image","title":"Research on high-speed wireless","body":null,"created":"1449177425","gmt_created":"2015-12-03 21:17:05","changed":"1475894649","gmt_changed":"2016-10-08 02:44:09"}},"media_ids":["72009","72010"],"related_links":[{"url":"http:\/\/www.gedcenter.org\/","title":"Georgia Electronic Design Center"}],"groups":[{"id":"1188","name":"Research Horizons"}],"categories":[{"id":"153","name":"Computer Science\/Information Technology and Security"},{"id":"143","name":"Digital Media and Entertainment"},{"id":"145","name":"Engineering"},{"id":"135","name":"Research"}],"keywords":[{"id":"7556","name":"data-transfer"},{"id":"7557","name":"throughput"},{"id":"1146","name":"transmission"},{"id":"1526","name":"wireless"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[],"invited_audience":[],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[{"value":"\u003Cstrong\u003EJohn Toon\u003C\/strong\u003E\u003Cbr \/\u003EResearch News \u0026amp; Publications Office\u003Cbr \/\u003E\u003Ca href=\u0022http:\/\/www.gatech.edu\/contact\/index.html?id=jt7\u0022\u003EContact John Toon\u003C\/a\u003E\u003Cbr \/\u003E\u003Cstrong\u003E404-894-6986\u003C\/strong\u003E","format":"limited_html"}],"email":["jtoon@gatech.edu"],"slides":[],"orientation":[],"userdata":""}}}
