Although impressive, Seimens' demonstration is for now just a demonstration. The 5 GHz band is a low-power, unregulated band not especially useful for wide-area broadcasts, and a seven antenna setup draws considerably more power than conventional mobile phone radios. Nonetheless, it shows promise for future wireless broadband options.">

Home / Cell phones Siemens claims 1 Gbps wireless transmission By Larry Garfield, Monday 13 December 2004 Siemens is claiming that it has set a new world speed record for wireless transmission, 1 Gbps in real time. The test transmission uses a 100 MHz wide band in the 5 GHz range, an unlicensed band also used by the 802.11a variant of Wi-Fi. Siemens used what it dubbed an "intelligent antenna system", consisting of three send and four receive antennas. The transmission was encoded using a new Siemens-developed signal processing technique and transmitted using Orthogonal Frequency Division Multiplexing (OFDM), an increasingly popular system for high-bandwidth wireless transmissions. Although impressive, Seimens' demonstration is for now just a demonstration. The 5 GHz band is a low-power, unregulated band not especially useful for wide-area broadcasts, and a seven antenna setup draws considerably more power than conventional mobile phone radios. Nonetheless, it shows promise for future wireless broadband options.     SUBSCRIBE RSS   |   YouTube   |   Facebook   |   Twitter SMARTPHONES HOTTEST   TOP-RATED   COMING SOON TOP STORIES Droid 3 by Motorola Review   Top 5 Big Screen Phones   Top 5 4G Phones - Summer 2011 Hottest Upcoming Phones   Top 10 T-Mobile Phones   Top 10 Verizon Wireless Phones NEW REVIEWS Motorola Droid 3 T-Mobile myTouch 4G Slide Samsung Gravity Smart Motorola Xprt HTC HD7S Samsung Exhibit 4G HTC EVO 3D Pantech Crossover HTC Sensation 4G RESOURCES EXPERT GUIDES   PRODUCT GUIDE   SIDE-BY-SIDE MOBILITY HEADLINES Android 4 Breaks New Ground (Part 6)   Android 4 Breaks New Ground (Part 5)   Android 4 Breaks New Ground (Part 4)   Android 4 Breaks New Ground (Part 3)   Android 4 Breaks New Ground (Part 2) Android 4 Breaks New Ground (Part 1) iPhone 4S Gets Official Release Date iPhone 5 Predicted As Sprint Exclusive Samsung Galaxy Tab 7.7 Offers Super AMOLED Plus Magic MOBILITY EDITION Check out infoSync Mobility, where you'll find in-depth coverage from the mobile world.   PHOTOGRAPHY EDITION Check out infoSync Photography, where you'll find in-depth coverage from the photo world.   GADGETS EDITION Check out infoSync Gadgets, where you'll find in-depth coverage from the world of gadgets.   DIGITAL HOME EDITION Check out infoSync Digital Home, where you'll find in-depth coverage from the CE world.
