4G- Launch in market in 2010

11 Aug

4G refers to the fourth generation of cellular wireless and is a successor to 3G and 2G standards. By using 4G technology you could download an entire movie in about a minute. A 4G system may upgrade existing communication networks and is expected to provide a comprehensive and secure IP based solution where facilities such as voice, data and streamed multimedia will be provided to users on an “Anytime, Anywhere” basis and at much higher data rates compared to previous generations. This 4G systems, the next generation of their old 3G systems which has 384 Kbps downloads and 129 Kbps uploads, could receive data at 100Mbps on the move and at up to a gigabit per second while static. 4G is being developed to accommodate the QoS and rate requirements set by forthcoming applications like wireless broadband access, MMS, video chat, mobile TV, HDTV content, minimal services like voice and data, and other services that utilize bandwidth.

Mobile TV – TV in your Hand

Objectives of 4G

* A spectrally efficient system.
* High network capacity: more simultaneous users per cell,
* A nominal data rate of 100 Mbit/s while the client functioning and 1 Gbit/s while client and station are in static.
* A data rate of at least 100 Mbit/s between any two points in the world.
* Smooth handoff across heterogeneous networks.
* Seamless connectivity and global roaming across multiple networks.
* High quality of service for next generation multimedia support (real time audio, high speed data, HDTV video content, mobile TV, etc).
* Interoperability with existing wireless standards, and
* An all IP, packet switched network.

4G features
According to the members of the 4G working group, the infrastructure and the terminals of 4G will have almost all the standards from 2G to 4G implemented. Although legacys systems are in place to adopt existing users, the infrastructure for 4G will be only packet-based (all-IP). Some proposals suggest having an open Internet platform. Technologies considered to be early 4G include: Flash-OFDM, the 802.16e mobile version of Wi-Max, and HC-SDMA.

Intel improves on mobile technology

08 Aug

WHILE Intel is popularly known for its Core i3, i5 and i7 line of microprocessors, the company has also been actively working on a number of technologies in the mobile computing arena.

In a recent event, the company provided updates on Intel Wireless Display as well as the Intel Atom processor and the company’s plans to eventually integrate the features into high-end smartphones.

PC to HDTV wirelessly

One of the interesting products currently shipping is based on Intel’s Wireless Display, which allows a user with a laptop to stream video and audio to a HDTV without cables.

Wireless Display technology works over WiFi and on the HDTV end, requires a set-top box to be plugged in via the HDMI interface.

According to David McCloskey, director of platform marketing and business operations for Intel Asia Pacific, while the slight lag in Wireless Display rules out PC gaming, the technology is ideal for displaying photos and even watching movies.

The technology is part of the 2010 Intel Core processor family, which includes certain models of the Core i3, Core i5 and Core i7 processors, along with a compatible wireless-N chipset.

The set-top box itself is a third party product – the model demonstrated at the workshop was a Netgear Push2TV device.

Power of the Atom

McCloskey also provided updates on Intel’s direction with the Atom processor, the low-power x86-based CPUs used in most netbooks.

According to McCloskey, Intel is set to ship dual-core versions of the Atom processor for netbooks by Dec 2010, based on the Pine Trail platform.

The upcoming Atom processor is still based on Pineview, which is the Atom CPU produced on Intel’s 45nm process with an integrated memory controller and GPU (similar to the currently shipping Atom N450 processors), which results in faster performance and lower power consumption.

The difference is that while dual-core Atoms have been available for the desktop for a while now, the upcoming dual-core Atoms will have the low power consumption required for mobile use.

Moving further forward, Intel is set to introduce the Oak Trail platform in 2011, which is the Atom platform optimised for “tablets and sleeker netbook form factors.”

With Oak Trail, Intel promises to reduce the average power consumption of the platform by up to 50%, while still offering full-HD video playback.

The ultimate goal for Intel is to integrate the Atom platform into even smaller devices, such as high-end smartphones and handhelds, which will require even lower and more efficient power consumption.

The company hopes to achieve this with the Atom platform formerly known as Moorestown, which will take the system-on-chip idea further.

The platform not only integrates the 45nm Atom core, graphics, video engines, and memory and display controllers but is also optimised for even lower power consumption than the Pine Trail platform.
