Get ready for blazing fast data transfer from a single chip for all cell communication networks.

 

Marvell Co-Founder Weili Dai proclaimed, "The World Modem is another game-changing breakthrough...  As a leader in China's 3G standard TD-SCDMA technologies, Marvell has enabled the delivery of a wide array of affordable, advanced consumer devices – including smart phones, tablets and mobile hot spot devices – to China, the world's largest mobile market. Building on that foundation, Marvell is now leading the way to a new era of seamless global connectivity for the masses with the industry's first single chip 2G/3G/4G modem with support for FDD-LTE, TDD-LTE, HSPA+, TD-SCDMA, and EDGE."

 

Combining 3GPP R9 Cat 4 FDD-LTE (Frequency Division Duplexing Long Term Evolution) and TDD-LTE (Time Division Duplexing Long Term Evolution) with R8 DC-HSPA+ (Dual Carrier Evolved High-Speed Packet Access) for both WB-CDMA (Wideband Code Division Multiple Access) and TD-SCDMA (Time Division Synchronous Code Division Multiple Access) standards and EDGE (Enhanced Data rates for GSM Evolution) will deliver the highest data rate available in any given geography.

 

Dai continues on about the new single-chip world modem and its future applications, "I envision a time soon when a truly affordable global communications network helps to bring our world closer as consumers from every walk of life enjoy uninterrupted access to all services, applications and the worldwide cloud from any device they choose anywhere they roam. I am proud of Marvell's global team of engineers for their pioneering work and I am excited by all the potential applications our customers will have to use this versatile and affordable new technology to make the world a better place for everyone." This low-cost extremely versatile and reliable modem is easily adaptable to any network so keep your eyes peeled at Marvell.

 

It looks like WiMax is the loser in the 4G race, according to Marvell.

3-D movies on cell phone

At the Mobile World Congress in Barcelona, German researchers demonstrated a mobile radio standard of LTE-Advanced video coding techique called Multiview Video Coding (MVC). The goal is 3D films on cell phones. Despite recent reports of children and adults having eye strain from using the Nintendo 3D gaming device the 3DS, Researchers  at the Fraunhofer Institute for Telecommunications,  Heinrich-Hertz-Institute, HHI in Berlin have decided to go ahead on this project. The have created a compression algorithm that works well with HD video. Thomas  Schierl is a scientist at the HHI explains, “MVC is used to pack  together the two images needed for the stereoscopic 3-D effect to  measurably reduce the film's bit rate,.The 2-D and 3-D bit streams  divided up by MVC can be prioritized for each user at the air interface  to support different services, thus opening up a completely new field  for business models.” A novelty or a new standard indeed, it's going to happen.


With Sprint possibly switching from WiMAX to LTE, this will most definitely be in our forecast.

Bell_Labs_Antenna_CUBE.jpg

 

The world of mobile communications moves fast. With new mobile devices, new applications and ever-growing and changing consumer demands the wireless networks in use today have to evolve. Rather than take an incremental approach to meet these challenges, Bell Labs took a leap and developed a radically new approach to wireless technology. In order to do this, Tod Sizer, head of Bell Labs Wireless Research, challenged his team to think not just ‘outside the box’, but to think ‘inside the cube’. In six short months, the team developed a cube-shaped antenna that would fit in the palm of a hand, and was ready to test it with customers. “There are many different types and sizes of base stations, from very small to very large, depending on where they are located, such as in an urban or rural area. I realized that we needed to design a new and flexible type of antenna array for different environments - including one designed to the smallest possible size ( ‘invisible antennas’) in order to be flexible enough to meet the growing needs of all of our wireless service provider customers,” said Sizer. A radio antenna element is a component of an antenna system that transmits signals from the wireless base station to a wireless end-user using a mobile phone, smart device or laptop. By reducing the size of the element itself, an antenna array can be scaled to fit any wireless need simply by adding more of these elements to the array. Bell Labs wireless researchers weren’t daunted by the challenge of building something that was roughly ten percent of its current size. Several wireless research teams in Stuttgart and Ireland focused on different aspects of the problem, combining their unique areas of expertise to quickly resolve a myriad of technical challenges to reduce the antenna element’s size, improve energy efficiency and lower manufacturing expenses. The clever architecture of this new antenna is but one of the innovations critical to realizing Alcatel-Lucent’s unique lightRadio portfolio.
