Very soon you would not have to face the problems of rush hour or slow internet as the scientists have developed a new hardware that offers high-speed broadband connectivity consistently. Slow internet will just be history for you then.
Scientists develop a simplified receiver for optical access networks
According to researchers, the new tech allows dedicated data rates at more than 10,000 megabits-per-second (Mb/s) for a low-cost and fast broadband connection. Sezer Erkilinc, from University College London in the UK, said “By 2025, average speeds over 100 times faster will be required to meet increased demands for bandwidth-hungry applications such as ultra-high definition video, online gaming, and the Internet of Things.”
He further added that the future growth in the number of mobile devices, mixed with the promise of 5G to allow new services through smart devices, means they are likely to experience bandwidth restrictions. Erkilinc, who is the lead researcher of the study published in Nature Communications, added saying that their new optical receiver technology will help combat this issue.
Scientists have developed a simple to use receiver that can be used with optical access networks. Polina Bayvel, from UCL said that data is transmitted using different wavelengths, or colors of light to maximize the capacity of optical fibre links. Bayvel added, “Ideally, we’d dedicate a wavelength to each subscriber to avoid the bandwidth sharing between the users.” This simplified receiver has several advantages of coherent receivers but it is far cheaper, smaller and simpler. Further, it requires only a quarter of the detectors used in conventional receivers.
Thanks to a new tech, you may be able to charge your smartphone in seconds
Researchers have developed a new tech that will charge your smartphone in seconds. The new tech can improve energy-storage devices dubbed supercapacitors significantly. The design increases the amount of electrical energy that the charging devices can hold by almost twice.
According to researchers this tech can eventually be used in everything from laptops to smartphones to high-powered lasers to electric cars. Michael Pope, professor at the University of Waterloo in Canada, “We are showing record numbers for the energy-storage capacity of supercapacitors. And the more energy-dense we can make them, the more batteries we can start displacing.”
Pope, who also led the research published in the journal ACS Nano, has developed a method with the help of his colleagues to coat atomically thin layers of a conductor called graphene with an oily liquid salt in supercapacitor electrodes to boost the capacity of supercapacitors. The researchers said that ramping the storage capacity of supercapacitors means that they can be made so light and small that they can replace batteries for more applications, especially for ones that require quick-charge and discharge capabilities. Pope said, “If they are marketed in the correct ways for the right applications, we will start seeing more and more of them in our everyday lives.”
