From Superfast to Ultrafast – Speedier Broadband on the WayOn the heels of BT offering to invest in the infrastructure needed to bring high-speed internet to those Britons who do not yet have it, researchers have announced the possibility of current technology becoming obsolete within a short amount of time. We aren't talking high-speed Internet any more. We're not even talking superfast. Instead, we are now looking at ultrafast speeds measured in gigabytes rather than megabytes. Ultrafast wi-fi has been on the radar for quite some time now. Until recently though, making it happen has remained somewhat of a mystery. That mystery may have been solved by switching from traditional microwaves to terahertz. Researchers at Brown University School of Engineering in Providence, Rhode Island (USA) have demonstrated they can “transmit separate data streams on terahertz waves at very high speeds and with very low error rates,” according a report on the Telegraph website.
“This is the first time anybody has characterised a terahertz multiplex system using actual data,” the researcher said in an official statement, “and our results show that our approach could be viable in future terahertz wireless networks.”
What It Means to YouIf you don't know the difference between a microwave and a terahertz, you are not alone. Here's what it means to you in simple terms: ultrafast internet access that could be upwards of 100 times faster than the best high-speed service now available. We are looking at speeds of 50 GB per second as opposed to 500 MB per second, the highest speed available with state-of-the-art microwave technology. If science is successful in developing terahertz applications, the implications of the new technology would be incredible. First and foremost, terahertz networks would bring to an end the very real danger of outstripping microwave capacity with current high-speed applications. Secondly, we would be able to develop platforms capable of much higher data densities. Terahertz waves operate at higher frequencies than microwaves and higher frequencies means more data packed into the same stream.
Thirdly, a successful venture into terahertz technology would mean high definition streaming on-the-go for everything from live television to superfast data crunching for banks, businesses and other large consumers of data. That alone would do wonders for worldwide financial markets.
