News.com's Ben Charny contributed to this report. CFO Scott Sullivan is fired after an internal audit finds improper accounting of almost $4 billion in expenses. WorldCom plans to restate earnings. In a statement issued late Tuesday, the company said an internal audit revealed that expenses had been booked as capital expenditures. Taking the new information into account, the company said it would have reported a net loss for 2001 and the first quarter of 2002. "As a result of an internal audit of the company's capital expenditure accounting, it was determined that certain transfers from line cost expenses to capital accounts during this period were not made in accordance with generally accepted accounting principles," the company said.

CNET también está disponible en español, Don't show this again, But equipment makers like Motorola; Western Multiplex, which recently merged with Proxim; and Alvarion have begun dabbling in the 5GHz range, It's free and love mei powerful iphone 6s / 6 protective case - black reviews can be used to create a powerful signal needed to deliver broadband access through the air for miles at a time, For instance, Canopy's equipment can serve an area with a radius of between two and 10 miles, Freedom comes with a price, however, Because the spectrum is unlicensed, there are no requirements to muzzle a signal that's powerful enough to interfere with others, analysts say..

Yet, "unlicensed has more promise because the other spectrum costs so damn much," said Brad Baldwin, broadband technologies analyst at research company IDC. To succeed, fixed-wireless equipment using the 5GHz band will have to do what earlier versions using the pricier airwaves could not: entice broadband providers to use it. Baldwin said "it hasn't been a banner year for fixed wireless," with providers like Sprint no longer adding new customers to its fixed-wireless service and AT&T Wireless selling its fixed-wireless business to Netro for "a song," about $45 million.

The newer efforts, using the 5GHz spectrum, are beginning to win some favor but mostly with the smaller Web providers that can't extend their networks by digging trenches to lay miles of fiber-optic cable, Baldwin said, Though it was just unveiled Tuesday, about 45 Web providers are already using Canopy, said Tony Kobrinetz, vice president and love mei powerful iphone 6s / 6 protective case - black reviews general manager of Motorola's Canopy wireless broadband products, Motorola "came in late to the market, and they looked like they did their homework well," said Tracy Wheatley, founder of Cascade Networks, which uses Canopy to serve about 300 customers in a community about 30 minutes north of Portland..

The company unveils equipment that uses unlicensed spectrum to wirelessly blast broadband Net access to hard-to-reach homes and businesses. The spectrum's free, but not perfect. The Canopy system uses the 5GHz range of spectrum. Increasingly, this area of radio waves, made available for public use only recently, has been the choice for makers of similar kinds of "fixed wireless" equipment. In a fixed-wireless system, broadband Web access is beamed from an antenna fixed onto a tower. The signals are sent to another antenna similar in shape to satellite TV dishes on a rooftop. Most fixed-wireless systems have been using spectrum that needs to be licensed from the government.
