The International Telecom Union (ITU) has set out a preliminary set of definitions for the fifth generation of mobile networks. In a recent conference held in San Diego from June 10th to 18th, a 12-member delegation decided upon the specifications of this network which is expected to have a speed that would be 20 times faster than the current 4G network.

The group decided that the data speed for the 5G network would be around 20Gbps (Gigabits per second) which is almost 20 times faster than the 4G network which provides a speed of only 1Gbps. With a speed of 20 Gbps, users will be able to download HD movies within seconds and surf the internet faster than ever. A very high resolution of video content and holographic technology via networks can be easily accessed by the users. While Indians are yet to grace the 4G network more widely, the world is already gearing up for the fifth generation. The 5G network is most likely to be named as IMT 2020. However, a huge challenge for this network would be the issue of standardization and bringing together the major telecom operators around the world to settle for a similar set of regulations. The IMT 2020 systems will be designed to deal with a potentially wide range of fields like healthcare, robotics, virtual reality and industrial automation. It is going to significantly transform wire353682less communications as a part of its predicted functioning which is likely to match the speeds and reliability achieved by fiber-optic infrastructure. With instant connectivity and high speed surfing options, 5G network is about to bring in a huge revolution in the telecom sector.

The final confirmation for these specifications will be done in the month of October 2015, after an approval from the 193 member nations of ITU. This 5G network is expected to be rolled out in 2020 commercially, with a prior demonstration of the technology at the 2018 winter Olympics in Pyeongchang, South Korea. Sources revealed that by 2019, the international spectrum for the 5G network will be distributed across the globe.

NASA’s TESS Discovers New Worlds Only 5 Months After Its Launch

With four special cameras, TESS uses a detection method called transit photometry.

A planet-hunting orbital telescope designed to detect worlds beyond our solar system discovered two distant planets this week five months after its launch from Cape Canaveral, Florida, officials said on Thursday.

NASA’s Transiting Exoplanet Survey Satellite, better known as TESS, made an early discovery of “super-Earth” and “hot Earth” planets in solar systems at least 49 light-years away, marking the satellite’s first discovery since its April launch.

TESS is on a two-year, $337 million mission to expand astronomers’ known catalog of so-called exoplanets, worlds circling distant stars.

While the two planets are too hot to support life, TESS Deputy Science Director Sara Seager expects many more such discoveries.

“We will have to wait and see what else TESS discovers,” Seager told Reuters. “We do know that planets are out there, littering the night sky, just waiting to be found.”

TESS is designed to build on the work of its predecessor, the Kepler space telescope, which discovered the bulk of some 3,700 exoplanets documented during the past 20 years and is running out of fuel.

NASA expects to pinpoint thousands more previously unknown worlds, perhaps hundreds of them Earth-sized or “super Earth” sized — no larger than twice as big as our home planet.

Those are believed the most likely to feature rocky surfaces or oceans and are thus considered the best candidates for life to evolve. Scientists have said they hope TESS will ultimately help catalog at least 100 more rocky exoplanets for further study in what has become one of astronomy’s newest fields of exploration.

MIT researchers on Wednesday announced the discovery of Pi Mensae c, a “super-earth” planet 60 light-years away orbiting its sun every 6.3 days. The discovery of LHS 3844 b, a “hot-earth” planet 49 light-years away that orbits its sun every 11 hours, was announced on Thursday.

Pi Mensae c could have a solid surface or be a waterworld as the composition of such planets is a mixed bag, Martin Spill, NASA’s program scientist for TESS, said in a phone interview.

The two newest planets, which still need to be reviewed by other researchers, offer the chance for follow-up study, officials said.

“That, of course, is TESS’ entire purpose — to find those planets around those brightest nearby stars to do this really detailed characterization,” Spill said.

With four special cameras, TESS uses a detection method called transit photometry, which looks for periodic dips in the visible light of stars caused by planets passing, or transiting, in front of them. (VOA)
