T-Mobile US Inc. TMUS, the third largest U.S. national wireless operator, has decided to roll out 600 MHz wireless spectrum in its footprints by this summer. Low-band spectrum is essential for wireless operators as the signals can be transmitted over longer distances and through brick-and-mortar walls in cities. Smartphones for this radio frequency are likely to be made available by Samsung and other manufacturers this summer.

Automakers aren't too happy about a recent U.S. Federal Communications Commission (FCC) proposal, which uses part of the wireless spectrum assigned to vehicle-to-vehicle technology for Wi-Fi instead.
The FCC announced that it plans to free up 195 MHz of spectrum in the 5 GHz band for unlicensed use in an effort to address the U.S.' spectrum crisis. This could potentially lead to Wi-Fi speeds faster than 1 gigabit per second.

For the first time in almost 30 years, a US carmaker is planning to market a non-truck diesel vehicle in the US. Estimated MPG for the automatic transmission version is in the mid 40's, which is better than the only other small diesel sedan sold in the US (the Volkswagon Jetta), and slightly better than their gasoline powered "Eco" model... I'd like to know what the MPG on the 6 speed manual version is.

Defense consortium hypersonic vehicle breaks a record:
"Its scramjet engine accelerated the vehicle to Mach 6, and it flew autonomously for 200 seconds before losing acceleration. At that point the test was terminated. The Air Force said the previous record for a hypersonic scramjet burn was 12 seconds.
Joe Vogel, Boeing's director of hypersonics, said, "This is a new world record and sets the foundation for several hypersonic applications, including access to space, reconnaissance, strike, global reach and commercial transportation."
With this and the X-47B, there seems to be a renewed interest in extreme performance (in terms of flight envelope) vehicles..

Stock market's extraordinary volatility may have been caused by fat-fingered entry.
Article is reporting that the catalyst for today's extradorinary price swing (at one point the Dow lost almost 9 percent in less than an hour) may have been because a trader entered a 'B' for billions instead of an 'M' for millions on a trade of Procter and Gamble:
"According to multiple sources, a trader entered a "b" for billion instead of an "m" for million in a trade possibly involving Procter & Gamble, a component in the Dow. (CNBC's Jim Cramer noted suspicious price movement in P&G stock on air during the height of the market selloff."

Unbelievable there are no safeguards to protect against this.

"How well will General Motors' Chevrolet Volt drive once it gets past its 40 mile all-electric driving range and starts to rely on power generated by its gasoline engine? That's been a question for both critics and fans of the Volt, and with just 11 months to go before this car hits the market, I got the answer."
Performance review of the Chevy Volt, paying particular attention to what happens after the initial plug-in capacity has been depleted. The review indicates that the performance is adequate, if not better than expected.
If the volt can deliver technically, especially with the possibility of it it retailing for less than expected ( http://online.wsj.com/article/BT-CO-20100107-708608.html?mod=WSJ_earnings_MIDDLETopHeadlines), does GM have a potential hit on its hands?
