Spectrum will take approximately three years to fully develop
In 1997 theÂ U.S. Federal Communications CommissionÂ sold hundreds of spectrum licenses to AT&T, Inc. (T) and other carriers, raising $14.7M USD. Â The only problem was that the spectrum in question lay adjacent to Sirius XM Inc.’s (SIRI) satellite radio band, and it was feared that if AT&T made use of its new spectrum it would cause interference. Â Despite the fact that the FCC willingly sold the licenses to AT&T — or other carriers which in turn sold it to AT&T — it refused to authorize the use until Sirius XM and the carrier worked out a deal.
I. FCC Keeps the Good Times Rolling for AT&T
For over a decade that deal was never reached and the spectrum — in theÂ so-called WCS (Wireless Communications Service) band — went unused. Â
But earlier this year Sirius XM and AT&TÂ finally settled their differencesÂ after AT&T promised to set aside some of the spectrum to use as a “buffer” — unused space between the two company’s holdings, designed to prevent interference.
The FCCÂ gave the deal its blessingÂ in October, and AT&T was officially in the WCS game. Â It then closed a set of deals with Comcast Corp. (CMCSA) and Horizon Wi-Com, a startup which rode the now-defunct WiMAX 4G standard, to acquire 608 more WCS licenses (enough spectrum to cover 82 percent of the population in 48).
The FCC this weekÂ approvedÂ those license transfers.
II. A Long Road to Better CoverageÂ
Between the October and December approvals, AT&T now hasÂ a lot of spectrumÂ on its hands to improve its service. Â But it will take a lot of work to do that. Â By AT&T’s best estimate it will take “approximately three years” to fully leverage the new spectrum.
On the network side AT&T has to upgrade its base-stations; in some cases this may consist of a simple firmware upgrade, in other cases new hardware may be necessary to broadcast in the newly acquired chunks of WCS space.
On the device side, the broadcasting support is useless, if the chips in smartphones aren’t designed to make use of the space. Â Again, here a mix of firmware and hardware (antenna, etc.) modifications will likely need to be applied in order to send and receive signals clearly on the new chunk of spectrum.
AT&T hopes to turn off its current fallback 2G network (EDGE) in 2017. Â It has begun the work to shuffle some 2G spectrum to 3G (HSPA+) and 4G (LTE) offerings, but again this will be a slow transition. Â AT&T alsoÂ plans to activate “advanced LTE”, which is expected to include voice-over LTE in 2013 (currently AT&T’s 4G LTE network is only used for data traffic).
The carrier is theÂ nation’s second largestÂ and twentieth largest carrier in the world, serving approximately 100.7M USD device-owning Americans.
Details on the next generation Tegra 4 processor, codenamed “Wayne”, leak
NVIDIA has done pretty well on the mobile market with its Tegra 3 processor, and it should be of no surprise to anyone that NVIDIA has been working on the next generation Tegra processor. The company even provided some rough details early last year. Â However, some detailed information on the next-generation 28nm Tegra 4 leaked today, and it promises six times the power of Tegra 3. Tegra 4 appears to be, according to a leaked slide, a 4+1 quad-core design similar to that of the current Tegra 3. The Cortex-A15-based Tegra 4 has 72 graphics cores and supports dual channel memory. Tegra 4 will also support resolutions of 2560 x 1440 for encode and decode and promises very low power consumption.
Other supported features will include the USB 3.0, making this the first NVIDIA chipset to support the new and faster USB standard.
With CES 2013 kicking off in mere weeks, we should have significantly more details coming in the not-too-distant future.Â
According to the information Nokia updated on the Mexico site, this new machine Lumia505 for the low-end market will be tailored to the Mexican carrier Telcel and it offers red, black and magenta three colors, and it is expected to be within the market in the coming weeks.
Nokia Lumia505 continues the past style in the appearance, the curved screen and colorful shell is still the most attractive in appearance. As for the configuration, this new machine is not so special, it is equipped with a 3.7 inches AMOLED WVGA resolution touch screen, joined Corning Gorilla Glass and ClearBlack technology, with 256MB RAM memory and 4GB ROM capacity, but it does not support memory card expansion.
Nokia Lumia505 is also loaded with Qualcomm Xiao Long processor, although the official did not disclose the specific model,according to previous news rumors there will be a 800MHz single-core processor, which makes the overall configuration of the machine is basically the same level with the Nokia Lumia510.
Nokia Lumia505 also has built-in 800-megapixel camera, but there is no Carl Zeiss lens, and also it does not support auto-focus function, and it can even only record VGA resolution video screen, while the lack of front camera is also regrettable. Still, the phone provides a thorough wireless connection, it supports WCDMA/HSPA network, Wi-Fi wireless Internet access and Bluetooth 2.1 technology.
The Nokia Lumia505 is also equipped with WP7.8 system, the upcoming new features will include providing new start screen experience, changeable dynamics magnet size.
The Nokia Lumia505 also has a big advantage that it has a long standby time, as equipped with a 1300 mA battery, it can support 36 hours continuous music playback time, and be able to get 7.2 hours talk time in 3G network and up to 600 hours standby time.
The Pew Research Internet Project released a report about Facebook on Friday, providing insights into the company that you won’t find in its IPO filing.
Rather than focusing on the company’s financials, the report “Why Most Facebook Users Get More Than They Give” sheds light on how Facebook’s 845 million users engage with Facebook and what they get out of it.
The findings show that social interactions on Facebook closely mirror social interactions in the real world.
For example, over the course of a one-month period, researchers found that women made an average of 11 updates to their Facebook status, while men averaged only six. Also, women were more likely to comment on other people’s status updates than men.
“There was a general trend in our data that women use Facebook more than men,” said Keith Hampton, a professor at Rutgers and lead author of the report. “This is a phenomenon that is not unique to Facebook. Women are traditionally in charge of social relationships offline, and that seems to be true of the online world as well.”
The report says men are more likely to send friend requests and women are more likely to receive them. That’s something else we see in the real world — especially in bars.
The report also says that most people who use Facebook get more out of it than they put into it, which may explain why they keep coming back.
Researchers found that 40% of Facebook users in a sample group made a friend request, while 63% received at least one friend request. They found that 12% of the sample tagged a friend in a photo, but 35% were themselves tagged in a photo. And each user in the sample clicked the “like” button next to a friend’s content an average of 14 times but had his or her own content ‘liked’ an average of 20 times.
Why the imbalance?
“There is this 20% to 30% who are extremely active who are giving more than they are getting, and they are so active they are making up for feeding everyone extra stuff,” Hampton said. “You might go on Facebook and post something and have time to click ‘like’ on one thing you see in your news feed, but then you get a whole bunch of ‘likes’ on your news feed. That’s because of this very active group.”
He also said extremely active users tend to have a niche: Some are really into friending, others are really into tagging photos, and still others click the ‘like’ button a lot. Rarely is any one user extreme in all those ways.
I asked Hampton what he could tell me about these extremely active people, whom he calls Facebook “power users.” Are they unstoppably social? Unemployed? Lonely?
“It could be people who are always active — whatever they are doing in their life, they are very active. Or it could be that just in the one month we observed them they are active and another month a different group of people would rise up,” he said. “It could be that there is something going on in their life that causes them to be very active, or it could be that some people think of it almost as a job to be active on Facebook.”
