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.

Imec saw a need in the market, inexpensive digital interface for radio networks, and filled it. With their development it looks like LTE has won the battle for 4G supremacy. The accelerated deployment of broadband personal communication coupled with the continuously increasing demand for large data rates results in an increasing spectrum scarcity. A dynamic access to the available spectrum would increase the throughput efficiency significantly. In licensed bands scenarios, dynamic spectrum access would for example allow personal mobile terminals to seamlessly set-up and maintain a reliable wireless connection. In unlicensed bands (the crowded 2.4 GHz band), it would bring great added value to products for which interruptions in the connectivity cannot be tolerated, for safety reasons in a control system (surveillance camera’s), or for comfort reasons in real-time applications (wireless conferencing, hearing aids,...) as it would improve connectivity even in the presence of many competing and interfering networks. Imec’s new spectrum sensing component was designed as a versatile digital engine to meet a wide variety of use cases, at low cost and low power overhead. The chip, which hosts a dedicated ASIP (application-specific integrated processor), can perform both flexible synchronization and spectrum sensing for high-throughput WLAN (802.11a-n), cellular standards (including the recent 3GPP-LTE), and digital broadcasting standards. The novel spectrum sensing component connects to imec’s in-house designed analog reconfigurable radio chip (SCALDIO) and imec’s programmable digital baseband platform conceived for 4G seamless connectivity (COBRA). As such, imec’s complete reconfigurable radio solutions enable multimode communication with efficient use of the spectrum.

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.
