Telecom Carriers Unveils 3G Network Construction Plans
BEIJING, Apr 10, 2009 (SinoCast Daily Business Beat via COMTEX) -- CHUFF | Quote | Chart | News | PowerRating -- Top executives for China's three integrated telecom carriers disclosed their 3G network construction progress and plans for the near future at the 2009 Mobile Communication Industry Summit Forum on April 9.
China Unicom Vice President Zhang Fan said that the company aims to achieve seamless switch between 3G and 2G networks. The 2G network, which has been upgraded, will undertake the traditional voice business. As for the 3G network, all base stations will be deployed with high-speed downlink packages access (HSDPA) and high-speed uplink packet access (HSUPA), with down-link speeds up to 14.4Mbit/s and up-link speeds up to 5.76Mbit/s.
Zheng Qibao, general manager for China Telecom strategy division, forecasted that the telecom operator's investment in base stations will leap 80% by the end of July 2009. Taking over the CDMA business in July 2008, China telecom saw its mobile phone subscribers increase 1.7 million in this February.
China Mobile plans to build approximately 140,000 TD-SCDMA new base stations in 2009-2011. The TD-SCDMA network is expected to cover 70% of the country at the end of 2009 and cover all Chinese cities at 2011-end. Totally, the number of TD-SCDMA base stations will top 160,000 by then.

Sprint's new ads stress savings, 3G network
Last month, I celebrated the fact that Sprint was killing its bizarre ad campaign with CEO Dan Hesse. Reader response to the blog was divided--some readers said they liked the ads, while others shared my joy. A Sprint spokesperson even chimed in to say that the ads "ranked among the best wireless ads in recent months for memorability."
Sprint also was good enough to send me its press release for two new TV, billboard, and Internet ad campaigns. The first, which (surprise!) features the Palm Pre (at least someone gets to touch it), revolves around Sprint's Now Network, aka the carrier's wireless broadband network. The central message appears to be the breadth of Sprint's network and the services, information and communication available on it. The campaign launched April 6.
You can see the video on YouTube and Sprint has launched a "Sprint Now widget" that gives you a taste of the campaign. On the widget is a treasure trove of random facts that will fascinate the trivia buff.
You'll find everything from Sprint-related factoids, such as how many text messages are being sent to the carrier's network, to the very non-Sprint-related, such as how many babies are being born right now. You'll also find completely useless information, such as how many people are stuck in elevators are this moment.
From the start, I found the widget utterly compelling, even if it was a little much for the eyes to take in at once. Why you need all the little people walking over the various tiles (see the widget), I don't know.
Yet, I dare to say that it could influence people to switch to Sprint. While it doesn't tell you why Sprint is better, it can get you excited about technology, communication, and the speed at which the two are conveyed. Bunker types may find it frightening, but that's a fair trade-off. You can download the widget if you wish, and I'm certain it will be available on the Pre once the phone goes on sale.
In another series of ads, which launched April 3, the emphasis is on saving money in a tight economy. According to Sprint's press release, "Sprint continues to emphasize that individuals and families can save a great deal on their wireless bills if they switch to Sprint from AT&T or Verizon." Perhaps you can't save by switching from T-Mobile.
I'll have to catch the full campaigns for my final verdict, but as long as I'm not watching Hesse walk through a black-and-white New York City (with the occasional Sprint yellow), I think it's an improvement. The San Francisco-based agency Goodby, Silverstein & Partners produced both campaigns.

T-Mobile expands its 3G network
T-Mobile USA plans to have more than 20 markets lit with 3G coverage when it begins selling the first ever Google Android phone in October. But will it be enough to entice smartphone consumers to choose the HTC Dream over the iPhone 3G or even the BlackBerry Bold?
The verdict is still out on that one.
Even though the Android-based HTC Dream hasn't been officially announced, most people believe it will support 3G speeds when T-Mobile unveils it next week. And given the fact that it will compete head-to-head with Apple's iPhone 3G and newer versions of Research in Motion's BlackBerry devices, it really needs to be 3G.
The biggest problem for T-Mobile has been its nearly nonexistent 3G network. T-Mobile launched its 3G service in New York in May. Since then, it has added service in 12 other markets including, Austin,Texas, Baltimore, Boston, Dallas, Houston, Las Vegas, Miami, Minneapolis, Phoenix, Portland, Ore., San Antonio, and San Diego.
And on Thursday T-Mobile said it would expand its 3G coverage from 13 markets to 27 markets by the end of the year. The expansion will provide 3G access to more than two-thirds of T-Mobile's current customer base, the company said. T-Mobile also plans to keep expanding coverage in 2009.
By mid-October, when the HTC Dream hits the market, the company will expand 3G coverage to additional markets including, Atlanta, Chicago, Los Angeles, Orlando, Fla., Philadelphia, Sacramento, Calif., San Francisco, and Seattle. And by the end of the year, six more markets will get 3G: Birmingham, Ala., Denver, Detroit, Kansas City, Memphis, Tenn., and Tampa, Fla.
Getting the 3G service up and running in as many markets as possible is key to T-Mobile's overall strategy. But even with the planned network expansion, T-Mobile will still be woefully behind its competitors when it comes to its 3G coverage.
Verizon Wireless and Sprint Nextel have the largest 3G footprints. AT&T plans to have 3G deployed in 350 markets by the end of the year, but it has still been criticized for not having enough of its network covered with 3G to satisfy some iPhone 3G users. T-Mobile's lack of 3G coverage could lead customers--even those who are hot to try an Android phone--willing to wait for a different Android handset on another carrier's network.

3G phone network standards vary by carrier
If you’re among the growing number of Americans using the Web or e-mail on your phone, the quality of that experience depends on your cell phone company's data network. Wireless carriers all make similar promises of blazingly fast mobile Internet, even more so now with 3G, or third-generation, wireless.
A speedy network with a strong signal brings faster-loading Web pages, quick e-mail delivery and smoother video streams on the go. Of course, sluggish data speeds and lousy network coverage means you'll likely wait until you get to work or home before jumping online via computer.
So what are the differences between the mobile Internet technologies and networks of AT&T, Verizon Wireless, Sprint and T-Mobile, the four major carriers in the United States?

AT&T Mobile 3G Network to Support Blazing 20 Mbps Speeds
Those on AT&T who are not enjoying the carrier's speeds on connectivity may have the possible summer launch of a new iPhone to thank. Ma Bell is supposedly performing massive network upgrades in preparation for a possible June iPhone launch according to Gizmodo. According to the report, AT&T may up its current network speeds of 7.2Mbps on the 3G mobile data network to 14.4 Mbps, with some coverage areas to receive an upgrade to 10 Mbps.
In addition to increasing the data speed, the carrier is said to be switching its data from the 1900 MHz frequency to the 850 MHz frequency. The 850 MHz frequency is credited for holding better signal strength and can operate better in densely populated areas with buildings and trees.
