Japanese cell carrier preps 250Mbps service


— 1:23 PM on March 26, 2008

If you've ever wanted to stream high-definition video to your cell phone, now you can—at least if you're part of trials being conducted by NTT DoCoMo. As PC World reports, the Japanese cell phone carrier has achieved a mind-blowing speed of 250Mbps (that's 31.25MB/s, if you're more comfortable measuring data speeds in bytes) in trials of a future third-generation cellular technology nicknamed "Super 3G."

Super 3G far outpaces current 3G standards, which currently allow speeds of "only" up to 3.6Mbps (450KB/s) via the High-Speed Downlink Packet Access (HSDPA) protocol through NTT DoCoMo's network. According to PC World, Super 3G has been in development since July 2006, and the technology is intended to "bridge the gap" between current 3G communications systems and future 4G systems. 4G trials by NTT DoCoMo have already yielded speeds of up to 5Gbps (625MB/s), or five times faster than the quickest residential fiber-optic services in Japan today. Those speeds were achieved while moving at 10 km/h (6.2 mph), too.

Of course, NTT DoCoMo doesn't plan to unleash 250Mbps services—let alone 5Gbps—on its network quite yet. PC World says the carrier plans to complete Super 3G development by the end of next year, which would position the launch of commercial services in 2010 "at the earliest."
