Does 4G Pose A Security Threat?
Could 4G Networks give way for more high-risk mobile security implications; Symantec is warning of such a wave of threats.
“We could see a move to the sort of threats that we already see on the wireless and fixed connected network,” John said. “Malware that you usually have on fixed networks, like botnets.
“There aren’t many botnets on mobile devices because the bandwidth’s not there to support it, once you go on to 4G [hackers] could start infecting systems.”
To ensure that enterprises avoid these these security threats, John advised that businesses need to be on their toes more than ever, look closely at everything that’s coming into the network, and not trust anything.
“Companies need to make sure that where traditionally it’s been a firewall with a perimeter with everything in a timeline environment,” John said. “What they need to look at is ‘what are my employees doing’, ‘what information is being shared’ and ‘how do we ensure our information is being protected no matter where it may be’, whether its mobile device, across networks or sitting in a cloud service.”
“This is a change we are going through, but 4G is going to push the need for that change even more so,” she added.
According to John, 4G will also be detrimental to businesses in the way it will add a greater burden for them to ensure that cloud services and mobility – what she calls “two of the biggest security challenges for enterprises and their employees” – are up to scratch.
Intel Buys Patents
Intel on Monday spent US$375 million to purchase nearly 1,700 wireless networking patents from subsidiaries of digital communications company Interdigital.
Intel will get patents that cover a range of 3G, LTE and Wi-Fi technologies from Interdigital. The patents should boost Intel’s product mobile product portfolio as the company establishes a presence in the smartphone and tablet markets, which is currently ruled by ARM.
Intel has said it will integrate 3G and 4G LTE capabilities along with its Atom microprocessor in devices like smartphones and tablets. Intel made its first entry into the smartphone market earlier this year with its Atom chip code-named Medfield, which is being used in handsets from Lenovo, Orange and Lava International.
Intel later this year will release a dual-core Atom Z2580 processor with 3G, 4G and LTE capabilities. Intel’s upcoming Atom chip for tablets, code-named Clover Trail, will also come with mobile broadband options.
Intel started building its wireless business following the acquisition of Infineon Wireless for $1.4 billion, which was completed last year.
Wireless is a fast-changing market, and the company is making this investment to support the business, according to Chuck Mulloy, an Intel spokesman.
“This was an opportunity to add some value to our patent portfolio. That’s over and above what we have,” Mulloy said.
Samsung Making Ultra MicroSD Card
Samsung Electronics has started mass producing a microSD card that uses an Ultra High Speed-1 (UHS-1) interface to greatly improve data transfer speeds, the company said in an announcement on Wednesday.
The microSD HC card stores up to 16GB and has a maximum sequential read speed of 80MBps (megabytes per second), according to internal tests conducted by Samsung. That is more than four times the read speed of today’s advanced microSD cards, which have speeds up to 21MBps, Samsung said.
What real-world speeds that will translate into remains to be seen. The card will be a good fit for LTE smartphones and tablets, according to Samsung.
Sprint Ending Lightsquared Relationship

Comments Off on Sprint Ending Lightsquared Relationship
Sprint Nextel will end its planned 15-year 4G network relationship with would-be hybrid network operator LightSquared, the Wall Street Journal reported on Thursday.
The end of the Sprint partnership, which was due to expire on Thursday, would be nearly as big a blow to the foundering LightSquared as the U.S. Federal Communications Commission’s proposal last month to revoke the carrier’s authorization to build a land-based network.
Since the deal was announced last July, Sprint had been planning to host LightSquared’s radio spectrum on its Network Vision infrastructure. LightSquared was to pay Sprint US$9 billion in cash for that hosting and said the plan would save it $13 billion over eight years.
For its part, Sprint had looked to the partnership for extra spectrum on which to run its own planned LTE network. It would get $4.5 billion worth of credits to use some of LightSquared’s spectrum in addition to its own and that of longtime partner Clearwire. Sprint extended the deal twice to give LightSquared more time to win FCC approval for its network.
Sprint will terminate the LightSquared deal on Friday and return $65 million in prepayments by LightSquared, according to the Journal.
New Chip To Cut Cost Of LTE Smartphones

Comments Off on New Chip To Cut Cost Of LTE Smartphones
Chip manufacturer Renesas Mobile has unveiled the MP5232, a processor that will allow vendors to build LTE (Long Term Evolution)smartphones with a price tag between $150 and $300, the company said Wednesday.
The big advantage of the 1.5GHz dual-core processor is that it is a single-chip product that can do both 3G and LTE, eliminating the need to use separate chipsets for the two technologies. A more integrated device results in a cheaper product that takes up less space and uses less power, according to Malik Saadi, principal analyst at Informa Telecoms and Media.
The cost is important, because for LTE to take off, there is a need for smartphones that cost less than current products, according to Renesas.
In addition to smartphones, the MP5232 can also be used to power tablets, said Renesas.
One of the challenges of developing chipsets for LTE is the plethora of frequencies used. Renesas hasn’t specified which bands the MP5232 can handle, but says it is designed to support all major operators and their respective requirements.
iPhone Adds To Sprint’s Losses

Comments Off on iPhone Adds To Sprint’s Losses
Sprint Nextel posted a bigger loss, reflecting the higher costs of offering Apple Inc’s iPhone. But the loss was smaller than expected because its signed up fewer new customers than expected.
Since Sprint subsidizes the cost of some of its phone sales, its costs rise and profit dwindles the more customers it wins. But since subscriptions fell short of expectations, its loss was smaller than expected.
Sprint’s loss was 35 cents per share excluding unusual items compared with Wall Street expectations for a loss of 37 cents per share, according to Thomson Reuters.
Its profit margin based on operating earnings before interest, depreciation and amortization (OIBDA) fell to 9.5 percent from 16 percent a year earlier but beat expectations for 8.6 percent, according to eight analyst estimates Reuters compiled.
“It’s still unbelievably depressed and subscribers were below expectations,” said Roe Equity Research analyst Kevin Roe who also noted that Sprint’s targets for the full year were not particularly impressive.
The margin decline was hurt by the hefty cost of selling the iPhone.
The FCC Gives AT&T The OK

Comments Off on The FCC Gives AT&T The OK
The U.S. Federal Communications Commission approved AT&T’s US$1.9 billion buying of spectrum from Qualcomm on Thursday, allowing the carrier to salvage one ambitious deal to acquire more spectrum, after squashing its planned merger with T-Mobile USA.
AT&T announced its plan to buy the Qualcomm spectrum last December, a few months before it revealed the much larger proposal to merge with T-Mobile for $39 billion. It said both were motivated by the need for more radio spectrum to increase the coverage and capacity of its LTE (Long-Term Evolution) network. AT&T withdrew the T-Mobile plan on Monday after the FCC, the Department of Justice and others said it was not in the public interest.
With the Qualcomm purchase, AT&T will get 6MHz of spectrum across the country in the coveted 700MHz band, as well as another 6MHz of spectrum in five major metropolitan areas: New York, Boston, Philadelphia, Los Angeles and San Francisco, according to the FCC’s order released Thursday. Those five markets represent about 70 million potential subscribers. The carrier has said it plans to use it as a supplemental downlink for its LTE network, allowing for faster and more consistent mobile data service.

Comments Off on Does LightSquared Interfere With GPS?
A second round of tests on LightSquared’s proposed land-based mobile data network again showed interference with a majority of GPS devices, except for cellphones, two U.S. federal departments stated Wednesday.
LightSquared wants to build a network of 4G LTE (Long-Term Evolution) base stations around the U.S. that would operate on frequencies close to those used by GPS (Global Positioning System) receivers. But the U.S. Federal Communications Commission (FCC) will not approve the company’s plan unless potential interference with GPS has been resolved. Tests earlier this year showed the network could cripple many GPS devices.
The second round of tests was conducted last month and concentrated on LightSquared operating in a lower block of frequencies farther from those used by GPS.
“Preliminary analysis of the test findings found no significant interference with cellular phones,” the Department of Defense and Department of Transportation said in a statement on Wednesday. “However, the testing did show that LightSquared signals caused harmful interference to the majority of other tested general purpose GPS receivers. Separate analysis by the Federal Aviation Administration also found interference with a flight safety system designed to warn pilots of approaching terrain.”

Comments Off on Galaxy Nexus 4G LTE Finally On Sale
Verizon Wireless finally announced that the Samsung Galaxy Nexus smartphone running Android 4.0 on its 4G LTE network will be available on Thursday in stores and online for $299.99 with a two-year agreement.
The announcement, which came late Wednesday, arrived after days of speculation that the phone was being delayed over a dispute between the carrier and Google over the Google Wallet application, which doesn’t work on Verizon’s version.
During the period many expected Verizon to release the Galaxy Nexus, problems with the carrier’s LTE network arose for nearly two days, pushing LTE users to Verizon’s slower 3G service.
But Verizon never admitted there was any delay in releasing the device and pointed out that it had never given an official release date until Wednesday.
Verizon will carry a 4G LTE version that supports download speeds of up to 12Mbps. Online sales were set to start at 1 a.m. ET Thursday.
The new device has many features putting it at the top of the market for competing smartphones, including one of the highest prices: $299.99. Many rivals are priced at $200 or $250 on other U.S. carriers.
