Wimax VS 3G. which is going to emerge?

The roll out of 3G is expected to shower in high speed data and advanced digital video streaming

With the Department of Telecommunications gearing up for simultaneous release of 3G and WiMax spectrum, analysts expect the two emerging wireless technologies to battle it out for supremacy.

WiMax or Worldwide Interoperability for Microwave Access is a telecom technology that enables wireless transmission of data. The technology is available as IEEE 802.16D (fixed) and IEEE 802.16E (mobile). It offers downloads of up to 70 Mbps as compared to the 15 Mbps that 3G provides. Mobile WiMax offers download speeds of around 20 Mbps.

In India, companies like Tata Communications Internet Services, Intel, Bharat Sanchar Nigam Ltd, Bharti Airtel and Reliance Communications are the proponents of WiMax. Most of the companies have had beta-runs of the technology.

Robodog to be the latest war flick

Modern battlefields may soon resemble something out of a science fiction flick, thanks to advances in robotics. And, the latest weapon to be unveiled is the robodog -- four-legged, petrol-powered robots.
Scientists have developed the 'BigDog', billed as "the most advanced quadruped robot on Earth", which they claim is able to carry up to four packs of military equipment on awkward terrain unsuitable for vehicles.

According to the scientists, who have developed the robodog for the United States Army, the 11-stone machine can trot along at up to four miles per hour and would even stay on its legs when it is kicked hard in the side — but, sadly, no wagging tail.

In fact, its legs are designed to work in a similar way to a real dog’s, even storing energy in shock absorbers when a foot touches the ground.

The 14-million-pound BigDog project is currently being tested across a five-mile trail used to train the United States Marine Corps, carrying the soldiers’ equipment to prove that it can cope with holes, steep slopes and water hazards.

However, the scientists are also planning to use the technology for non-military purposes.
