eastbayted writes "Samsung shifted wireless networking into a higher gear yesterday, demonstrating for the first time in public the power of it WiBro (Wireless Broadband) 4G technology. The company had two 4G demonstrations. A mobile stunt entailed providing delegates on a specially designed bus with a live broadcast of the forum, Internet access, and video on demand, all simultaneously at speeds of 100Mbps. Inside the forum venue, Samsung showed off its 1Gbps 4G service with 32 HD channel broadcast downloads, Internet access, and video telephony. The downside for users craving that kind of speed: WiBro won't be out until 2010, though Sprint has a 4G WiMax service in the works for later this year. The downstream speeds will be 2Mbps to 4Mbps, which seem downright sluggish — compared to WiBro."
