T-Mobile criticizes Sprint amid MetroPCS merger talk - KansasCity ...

T-Mobile USA took several digs at rival Sprint Nextel Corp. Monday in an effort to bolster its bid to merge with smaller cellphone company MetroPCS Communications Inc.

The comments came amid speculation that Overland Park-based Sprint might make a counteroffer for MetroPCS and its 9.3 million subscribers. Sprint has not responded to those reports and declined Monday to respond to T-Mobile?s commentary.During a conference call with analysts, T-Mobile?s chief technology officer Neville Ray took more than one swipe at Sprint?s disastrous 2005 merger with Nextel Partners and referred to Sprint?s wireless technology as ?dying.? Sprint uses technology called CDMA.T-Mobile, which is owned by Germany-based Deutsche Telekom, essentially beat Sprint to the deal last Wednesday by announcing its agreement to merge with MetroPCS. Sprint?s management reportedly had tried to acquire MetroPCS in February, only to be blocked by its own board of directors.The two rivals are battling for a boost to their customer counts in an industry dominated by Verizon and AT&T Inc., each of which has more than 100 million subscribers.Sprint is a bit more than half that size with 56.4 million customers. T-Mobile has 33.2 million.Ray spoke with investment analysts mainly to dispel concerns that T-Mobile and MetroPCS, which use different wireless technologies, could repeat the problems Sprint had in merging with Nextel.The Nextel merger is widely seen as a key reason Sprint has struggled financially.Nextel used a wireless network called iDEN, and now Sprint is shutting it down after years of burdensome costs from running two networks. The Nextel shutdown has buoyed Sprint?s recent prospects.Ray said T-Mobile wouldn?t make the same mistake though MetroPCS uses CDMA technology and T-Mobile uses yet another technology called GSM.?This is not about combining CDMA with GSM band technology,? Ray said. ?We?re going to close the CDMA network down.?Ray?s central message was that T-Mobile would migrate MetroPCS customers toward its network rather than run parallel systems.T-Mobile expects to be able to move most of them off MetroPCS?s CDMA network in only eight months after the deal is completed in mid-2013, according to Craig Moffett, senior analyst at Sanford C. Bernstein Co., the host of the conference call.Moffett, in a note to clients, said MetroPCS experiences lots of customer turnover, which gives T-Mobile a quick opportunity to upgrade them to phones that work on T-Mobile?s network. That would avoid ?the mess and cost? of trying to combine the different technologies, he wrote.T-Mobile said it would be able to shut down that network by the end of 2015, generating cost savings and other benefits from the merger. Ray contrasted that with Sprint?s experience with the Nextel network, which he said was an indication of what could happen in a Sprint/MetroPCS merger.?Track record is important in these things,? Ray said. ?That?s an interesting story I?d love to hear them tell.?He said Sprint would run into new troubles with a MetroPCS merger. The two companies use different wireless spectrum.Spectrum is essentially the licensed airwaves that cellphone companies use to carry their traffic. Ray said Sprint would need to install expensive equipment to its already complex multiple technology to use MetroPCS?s spectrum.T-Mobile and MetroPCS use the same wireless spectrum, which will make it easy for T-Mobile to put MetroPCS?s spectrum to new use as it migrates customers off the MetroPCS network.In another jab at Sprint, Ray called its CDMA technology a ?dying? one.T-Mobile?s strategy is to move all of its customers, including the MetroPCS subscribers, quickly to an advanced technology called Long Term Evolution, or LTE. LTE carries data ? such as videos and other downloads ? at far faster speeds and is being adopted industry wide.Sprint is rolling out LTE service as part of its Network Vision upgrade that also includes enhancements to its CDMA network that it will continue to use for voice traffic.Analyst Jennifer Fritzsche, who follows the industry at Wells Fargo Securities, said CDMA will be ?around for a long time? because a successor is not yet ready. Fritzsche also said T-Mobile was likely to face more difficulty with its plans for the MetroPCS switchover than it expected. The industry is riddled with such problems, she said, even if they?ve rarely risen to the level of difficulty Sprint had with Nextel.And that opens the door to rival carriers ? including Sprint ? to go after the MetroPCS customers as they change networks, Fritzsche said. Sprint has lost many of its Nextel customers as it tried to switch them to its CDMA network. About 40 percent are staying with Sprint, with the rest going elsewhere.Sprint has an opportunity to rebut Ray?s comments Wednesday. Joe Euteneuer, Sprint?s chief financial officer, is scheduled to talk with analysts at a conference in Arizona. It will be broadcast on Sprint?s website.

Catalytic converters like it hot

ScienceDaily (Oct. 8, 2012) ? Vienna University of Technology has successfully clarified what it is the required operating temperatures of catalytic converters in cars depend on.

Catalytic converters work poorly if they have not yet warmed up. Tiny metal particles in a catalytic converter require a minimum temperature to function efficiently. At the Vienna University of Technology, thanks to a new measuring method, it has now become possible to examine many different types of these particles at the same time. Reliable information regarding what it is exactly that the efficiency of catalytic converters depends on has thus been obtained for the first time.

Low ignition temperature desired

"A large part of the pollutant emissions from an engine are generated immediately after start-up, while the catalytic converter is still cold," explains Prof. G?nther Rupprechter from the Institute of Materials Chemistry at Vienna University of Technology. "Only when a certain temperature is exceeded does what is known as catalytic ignition occur and the catalytic converter functions with high efficiency." Complex and expensive catalytic converter heating systems have already been developed in order to reach this critical temperature as quickly as possible. It would, however, save both money and energy to build a catalytic converter that already functions well at the lowest possible temperatures.

Straight or slanting? It all depends on the angle

The critical temperature that the catalytic converter must reach depends on the material used: the precious metals platinum and palladium are used particularly often in catalytic converters. However, the crystallographic orientation of the surfaces of the tiny metal granules also plays an important role. Crystals can be cut in different highly-specific directions -- this process is familiar from cut precious stones. Even the surfaces of naturally grown crystals are formed in differing directions and the orientation of these surfaces determines the chemical behaviour of the crystals. "It is apparent that surfaces with differing crystallographic directions require different temperatures for catalytic ignition," explains Prof. Yuri Suchorski, who works with Prof. Rupprechter.

Many measurements in one experiment

Previously, it had hardly been possible to investigate this effect in detail: a catalytic converter is made up of countless tiny granules. "Until now, it has only been possible to measure the superimposed activity of all these differently-oriented granules," says Rupprechter. However, Rupprechter and his team have now been able to use a photoemission electron microscope based on Einstein's famous "photo effect" to analyse the ignition temperatures of the individual metal granules whilst the reaction is occurring. For this, a film was used, on which many tiny crystals -- with diameters of only around 100 micrometres -- were arranged closely together. The directions of the crystals were randomly distributed, thereby allowing different crystal variants to be investigated in a single experiment.

Under the microscope, the temperature of the film was slowly increased, actually demonstrating that the catalytic ignition took place at different temperatures depending on the direction of orientation. "It is important to us to be able to investigate different crystal grains in close proximity and under identical conditions during a single experiment," explain the researchers. "If you carry out several experiments one after another, it is never possible to perfectly reproduce the external conditions so that the individual measurements are directly comparable."

With the new findings, it is now possible to perform targeted searches for manufacturing processes for catalytic converters with lower ignition temperatures. "We now know that palladium works better than platinum, and we know which crystallographic direction promises the lowest ignition temperature," says G?nther Rupprechter. Now it should also be possible to implement these findings in technology, in order to build catalytic converters which take effect in cars as soon as possible after start-up.

Jack Osbourne and Lisa Stelly

By Us Weekly

It's been quite the year for Jack Osbourne.?The son of Ozzy and Sharon got engaged to love Lisa Stelly last September, welcomed daughter Pearl in April, and was diagnosed with multiple sclerosis in June. And now? Osbourne is officially a married man.?

PHOTOS: Hollywood's new star dads

The former reality star, 26, tied the knot with aspiring actress Stelly in an intimate Hawaiian ceremony Sunday, a source confirms to Us Weekly.

The couple first began dating in April 2011. After Osbourne's shocking MS diagnosis earlier this summer, a source close to the pair told Us Stelly was committed to standing by her man, and helping him cope with the disease.

"Lisa makes sure he's healthy -- eating right and exercising," says a friend of the duo. "They love staying active as a family."?

PHOTOS: Celeb health scares

Jack is also "a great influence on [Lisa]," another source shares. And their "stable" bond is "no drama," the source adds.

Jack and Lisa's nuptials won't be the only milestone the Osbourne family celebrates while they're in Hawaii: they'll most likely fete Jack's mom Sharon, too, as?"The Talk" host turns the big 6-0 on Tuesday.

US releases estimate of Utica Shale reserves

Drilling companies beginning to explore the Utica Shale got a piece of good news Friday when the U.S. Geological Survey estimated the rock formation in Ohio, Pennsylvania and other states holds enormous reserves of natural gas and oil.

Releasing its first estimate of the Utica, the USGS calculated the shale formation holds about 38 trillion cubic feet of undiscovered, recoverable natural gas, 940 million barrels of oil and 9 million barrels of natural gas liquids like ethane and propane.

The Utica lies beneath the Marcellus Shale, where energy companies have drilled thousands of unconventional gas wells in Pennsylvania in recent years. The Marcellus is considered to be one of the richest natural gas reserves in the world.

Drillers are just beginning to tap into the deeper Utica. Pennsylvania and Ohio have issued 452 Utica well permits to date, and 178 wells have been drilled, according to the most recent state data.

The geological survey's Utica estimate covered parts of Maryland, New York, Ohio, Pennsylvania, Virginia and West Virginia.

Such estimates are highly variable and subject to revision. The USGS estimated last year that the eight-state Marcellus region contains some 84 trillion cubic feet of undiscovered, recoverable natural gas, far more than its 2002 assessment of just 2 trillion.

"As more (Utica) wells are drilled and more production data is assessed, reserves figures will likely increase," said Steve Forde, vice president of the Marcellus Shale Coalition, a drilling industry trade group. He hailed the Utica as "another game-changing opportunity."

Domestic production of shale gas has soared in recent years as drillers perfected a technique called hydraulic fracturing, or fracking, and combined it with horizontal drilling to reach previously inaccessible reserves deep underground. The production boom has resulted in lower prices for consumers while stoking concerns about water and air pollution. The drilling industry says its practices are safe.
