What is swine flu?
Swine flu is a strain of Influenza A, which is most commonly found in pigs. It can be transmitted to people, most often those who work with livestock or at county fairs.Read More!!

On 20th of April, ISRO successfully launched its first all-weather radar imaging satellite, RISAT -2. The PSLV-C12 (Polar Satellite Launch Vehicle), carrying 300-kg RISAT and 40-kg micro educational satellite ANUSAT (developed by Anna University) lifted off from ISRO's Satish Dhawan space Centre here at 6:45 am and placed into 550 km orbit around earth.

The PSLV, weighing 230 tonnes at the time of launch, soared into a clear sky from the spaceport in Sriharikota, about 90 km north of Chennai. At the end of the 48-hour countdown, the 44-metre tall four-stage PSLV-C12 blasted off from the second launch pad with the ignition of the core first stage.

RISAT has all-weather capability to take images of the Earth and would also be beneficial in mapping and managing natural disasters, such as floods and landslides, besides amplifying defence surveillance capabilities of the nation. It would also help keep track of ships at seat that could pose a threat.

A jubilant ISRO Chairman G Madhavan Nair said "the year 2009 has started off well. The final moments of the launch were more thrilling than a cricket match as we hit a few boundaries and bowled some googlies." Nair said the performance of the PSLV-C12 launch vehicle was "precise and on the dot".

As per specifications, RISAT is different from previous remote sensing satellites as it uses Synthetic Aperture Radar (SAR), equipped with many antennas to receive signals that are processed into high-resolution pictures.

Are you waiting for the next wireless broadband technology? It will be a few years before we’ve access to broadband Internet services that are truly wire-free. However, the development of Long Term Evolution (LTE), the evolving 4G technology for high-speed data access over cellular networks, will be under the gun in 2009.
Despite a host of uncertainties about the pace of rollout for this flavour of mobile broadband, IC vendors are busy getting their designs ready for this emerging 4G technology.

Players in the consumer electronics sector want to avoid the mistakes encountered during the rollout of 2.5G and 3G networks, when interoperable handsets were not available in a timely fashion for the upgraded networks.


For LTE, the issue is more likely to be ensuring that LTE-capable devices are available for embedding into PCs and mobile computing devices rather than phones, since the initial emphasis is bound to be on high-speed data transfer rather than better and wider voice coverage. Terminal availability has too often been blamed for slow rollouts, due to endless options that have made the poor handset designers' and manufacturers' lives difficult.

This won't be easy since the standardisation process for LTE has some way to go, even though the important Release 8 for the technology, being devised under the auspices of the 3GP standard group, is due to be finalised this month. But as the industry is well aware, this will not be the end of the story.

There is too much uncertainty regarding the frequency ranges at which LTE will operate—anywhere between 900 MHz to 2.6 MHz. Network topology is also a subject of debate among operators: Will it be targeted at hot-spots only? Will LTE be a rapid replacement for 2G or 3G? Will it be for data only, or data and voice from the outset?

For chip designers, this means the need for greater flexibility and compatibility. Why? LTE is not the only game in town for 4G; mobile WiMAX is slightly ahead of the game. Chip, customer premises equipment (CPE) and terminal designers will need to ensure a single solution for broadband wireless, deploying base band and RF that support both environments.

We should not expect major LTE rollouts before 2010 for use with data cards and 2011 for handsets. The bottom line: LTE is specified to support multiple bands in both time division duplex (TDD) and frequency division, duplex (FDD) modes, and will evolve to be the first truly global standard for mobile data.
