A Short Introduction of TDS SCDMA In Nowadays’ Telecom System

   The TDSCDMA as the third generation mobile communications standard (referred to as 3G), since 1998, the ITU (ITU) to submit, after more than five years, completed the assessment of the Expert Group on the standard, ITU recognized and published3GPP (third generation Partnership project), system integration, new technology features the introduction of a series of international standardization work, so the TDSCDMA standards as first proposed by China, the China Intellectual Property-based, internationalwidely accepted and recognized international standard of wireless communication. This is an important milestone in the history of China Telecom. There are four international standard 3G, three other US-led CDMA2000 and Europe led WCDMA, and WiMax,

   Chinese meaning for TDSCDMA of the time division synchronous code division multiple access, the communication technology to a wireless communication technology standard, it is first put forward by the Chinese on the basis of the wireless transmission technology (RTT) and the International complete TDSCDMA standard, one of the CDMA TDD standards, this is the first initiative of the Chinese mobile communications industry, is also China's contribution to the development of third generation mobile communication. Competition in Europe, the United States each 3G standard China proposed TDSCDMA has officially become one of the global 3G standard, which marks that China has entered the list of the world's leading in the field of mobile communications. The program's main technology is concentrated in the hands of Datang, it designed in accordance with the TDD (time division duplex) in the unpaired band time-domain model.

Mobile Telecom Communication System Designed Specifically for Special People

   In nowsdays telecom system,this set called Communicaid series of products designed from the hands of designers Jae Pyung Lee, the purpose of design is communication for the deaf and hard of hearing people. Visualization of the sound stops and glasses, indoor and outdoor use of portable devices. It captures the importance of environmental sound and visual alert deaf people. Mobile communication is a handheld communication equipment, more efficient and more easily communicate with hearing people. The Communicaid visual voice station high-quality MEMS microphone to capture a particular sound, such as fire alarms, doorbells, or individual call, and transfer them to the flashing lights and pictographic visual queue. Visual voice glasses monitor environmental sounds, and then converted to specific sounds in their immediate visual signal. It can capture a particular sound, through glasses weapon. Mobile communication devices enabled mobile phone features such as video telephony, text messaging, e-mail to make and receive calls with any person using text, voice and voice to text technology.

What’s 5G Cell Phone?

  It isn’t a long time for the development of mobile phone technology.we public people have been in a great convenience for the 3G phone.However,with the increasing needs for the 3G phone and a more comfortable and frequent way in communication across mobile devices,a more developed telecom technology is been on researched for the right time.

  Not like the 3G phones or 4G phones,the fifth generation cell phone,we call 5G phone,has its unique and special improvement,which is called the really revolution of the telecom technology.The fifth cell phones standard was realeased during the time of this text.It’s certainly that the 5G phones ‘ data rate and download or upload speed will have a rapid improvement in contrast with 3G phones,but actually most of the researcher agree that it will focus more on the quality of service,which is the significant demands for mobile users,moreover,the bandwidth will grow with the added support and the connection for mobile phone will be more stability.

  Though the 3G phones are now making its hit,it’s belevied that for the near future(in 2020) the 5G phones will be created for the first time.During that time,mobile devices data is forecast to grow by some 50 comparing to the data rates used today.

The Timeline of Cell Phone Making You More Understand The 3G Phones

  1840–Michael Faraday conducted an experiment on the electricity in space,then it began the history of the cell phone as early as that research.

  1843–Michael Faraday having a test on the ability for space to conduct electricity.It’s said that it is that experiment set on the stage for the following other scientist to continue their research and bury them into the electricity and radio frequency.

  1865–Dr. Mahlon Loomis,half scientist half dentist,creates a communication way by using the electrical conductor.In this method,he uses two kites that are embedded with wires and screens to connect to the ground on mountains in every 18 miles from one another.

  1940–Mobile radios have increased from 30MHz to 40MHz frequency band and the using across police departments become fairly casual.A great deal of the pricate companies begin their exploration of commercial use.

  1975–The FCC cell phone test approves the success and Bell Telephone Company who is in partnership with AT&T,got its license.

  2002–In United States,it launched the first 3G phone networks and South Korea and Europe quickly followed.

  2011-The introduction of iphone 4S which is support for both GSM and CDMA on a single cell phone chip.

Sony Xperia P

The Sony Xperia P wins with its unusual looks, including the classy silver back and see-through shortcut bar. It is resistant to scuffs but the lip does add some width.

The 8-megapixel snapper produces top daylight images, as well as offering a panoramic facility and shooting 1080p HD video. The display shows off photos and films well, and is good for surfing the net too. Plus the in-built NFC offers a degree of future-proofing. The dual-core chip ensures the Xperia P runs apps and games smoothly – and offers a degree of future-proofing for future titles.

The social media offering is still Sony’s Timescape widget, which is far from well-designed – it streams updates from Twitter and Facebook but never seems to manage to update automatically – and the small window can only fit in two messages at any one time. The news widget is equally unimpressive, although the power tools are handy for quickly switching GPS, Wi-Fi and so on, off and on.

LG Optimus L7

LG is making much effort to work on the design of its smart phones of late – first there was the very sexy Prada Phone 3.0, and then the stylish L series of handsets. Then there was the Optimus L3, which despite being a budget-price phone, boasted a very attractive chassis. The big brother of the L-series is the latest Optimus L7, which has more power, a larger display and yet is a slender and good-looking phone to boot.

It’s easy to see that LG has concentrated on the handset’s design. The chassis is slim and solid, and feels classy thanks to that front covered in glass. It also resists scuff well.The single-core chip is not always up to the task of running Ice Cream Sandwich, or surfing the net – and it can’t compete with the futureproofing provided by a dual-core processor.

Nokia Lumia 900 Getting Windows Phone 7.8

Microsoft confirmed that current Windows smartphones won't be upgradeable to Windows Phone 8. However, a number of its features will be included in the Windows Phone 7.8 update which Nokia have now confirmed is coming to the Lumia 900.

This information has originated from Nokia's US Twitter page, but we presume the update will come to the Nokia Lumia 900 in the UK when the smartphone finally becomes available.The only information currently confirmed about the Windows Phone 7.8 update is that it'll bring support for the "New Start Screen" featured on Windows Phone 8.The new Start Screen which now uses the whole width of the Lumia 900's display which leaves more space for tiles. Infact, you can now add tiles in new sizes with both larger and smaller tiles now available meaning you can get the layout you always wanted.

  3G are hoping to review Nokia's flagship Windows smartphone very soon so keep posted !

iPhone 5 To Feature New Mini Dock Connector

It is said that the iPhone 5 would adopt a new "Mini Dock" connector and the rumors have now resurfaced in a fresh leak reported by TechCrunch.

 The information was gleaned from a leaked picture of the iPhone 5, shown above, which clearly shows a new smaller "Mini Dock" port. Apple's devices have featured a 30-Pin Dock connector for a long time,  but this is expected to  be replaced by a 13-Pin Dock adapter with the launch of the iPhone 5.The change of standard in the iPhone 5 means all previous accessories will now be incompatible with the iPhone 5 , even if the software is capable of being updated. Accessory manufacturers will now have to reconfigure their machines to produce the Micro-Dock port and will essentially have to remake all of their hardware to support the iPhone 5.

3G doesn't blame Apple for updating and feels it will be a smart move long term, but it'll be a shock to everyone's system originally. However, with the iPhone 5 expected to be a revolutionary product it seems the most logical time to shake things up.

LG Optimus 4X HD

The LG Optimus 4X HD's with its simple, sleek design and lightweight build (considering its size -- it weighs only 5.12 ounces), it's a tall device. Measuring 5.19 inches long, 2.69 inches wide, and 0.38 inch thick. The display also has In-Plane Switching technology which maximises viewing angles and ensures it has amazing colour reproduction. Other features include an 8 mega-pixel camera and a front-facing 1.3 mega-pixel camera.

LG's Optimus 4X HD is a real beast that comes with a quad-core Nvidia Tegra 3 processor which runs at a clock speed of 1.5 GHz. The Android smartphone also has 1GB of RAM and 16GB of on-board memory and runs on Android Ice Cream Sandwich.

Under the 4X's plastic bonnet is Nvidia's latest Tegra 3 processor, offering four main 1.5GHz processing cores, plus a fifth for battery-saving purposes. This same chip can be found lurking inside the Asus Transformer Prime tablet -- so it's a serious amount of welly for a pocket rocket.

The chip's fifth core is used for less demanding tasks, such as when the phone is idling in standby but still running live widgets in the background. The idea behind it is that the phone can switch to this lower-powered core to make more economical use of battery life, turning to the main cores when you fire up more demanding apps.

Samsung Galaxy S III

The Samsung Galaxy S3 comes fully loaded with Android 4.0 Ice Cream Sandwich, 4G LTE/HSPA+ 42 capability, a zippy dual-core processor, and a strong 8-megapixel camera. S Beam is an excellent software enhancement, and the handset's price is right.

It won't wow you with neon colors or evocative, industrial design; it doesn't have the sharpest screen on the market; and its body isn't fashioned from ceramic, glass, or micro-arc oxidized aluminum. That said, the Galaxy S3 is about the nicest plastic phone I've ever seen. Likely tired of hearing complaints about how cheap-feeling Samsung phones can be, the company decided to focus instead on making the contours more premium -- without giving up its light, inexpensive, and shatterproof material of choice.

The GS III loses out to the One X on a few scores but beats it on others. It does particularly well on the SunSpider score, which reflects web-browsing performance: it's on a par with the One X here, and well beyond the latest Apple A5-based devices –- for instance, the new iPad only scores 2,011ms. If we look at Tegra 3 devices, like the global version of HTC One X, which isn't listed on the table above, we see a similar picture of the GS III winning on some and losing on a couple (namely CF-Bench and Quadrant). Overall, we'd have to call it a draw between the GS III and either variant of the HTC One X, at least on the basis of these specific tests.
