That means I can use this technology to piggy back existing Fibre connections to even create speeds beyond 100 to 1000 to 10,000 times the present technology and capacity. I can modify existing 5G networks into an OPEN or CLOSED network, where police, security and medical personnel can use the OPEN network, and the rest of the world to use the CLOSED network, even 5G wireless routers can support this feature, when the technology of using sound to piggyback on existing fibre can increase your capacity up to 10000x and 100000x times, all it takes is a slight modification which can be tested and implemented in months, before we implement our 5G networks in 2020. I can even use a VPN service to secure this OPEN network, which most countries do not implement this layer of security in their 5G networks. You can use existing 4G Fibre networks to upgrade to 5G. All you need to do is make sure your new 5G equipment conforms to the spectrum you are allocated, which can be easily customised to handle both OPEN and CLOSE, as it is unlikely to exceed your capacity, even for Wireless routers.

Scientists have perfected a new technology that can transform a fibre optic cable into a highly sensitive microphone capable of detecting a single footstep from up to 40km away.
Guards at listening posts protecting remote sensitive sites from attackers such as terrorists or environmental saboteurs can eavesdrop across huge tracts of territory using the new system which has been created to beef up security around national borders, railway networks, airports and vital oil and gas pipelines.
Devised by QinetiQ, the privatised Defence Evaluation and Research Agency (DERA), the technology piggybacks on the existing fibre optic communication cable network, millions of miles of which have been laid across.
Trials have already been staged in Europe to use the OptaSense system, which evolved out of military sonar and submarine technology, on railways to prevent vandals or thieves trespassing on high-speed lines as well as to counter terrorism. It has been deployed by several blue chip oil companies to protect energy pipelines which run through some of the most lawless and remote regions of the world.
Oil and gas companies lose millions of pounds each year through “hot tapping” in which thieves siphon off oil to sell. The process can be dangerous, resulting in explosions which have claimed hundreds of lives as well as causing serious environmental damage. Its creators say the system can also safeguard against accidental damage caused by builders and farmers working close to pipelines in Europe and North America. But it is hoped the technology will be rolled out to enhance security arrangements at prestige sites, among them Heathrow’s Terminal 5 or the Olympic Games and to protect major gatherings of world leaders such as during the G8, which has become an increasing magnet for protest movements.
Darpa has a project that protects undersea oil pipelines with sound sensors that can listen to any meddling of it’s oil pipelines via fibre optics. This technology can be modified to piggy back on multicores fibres using Sound to travel beyond the Speed of Light for transmission of huge data beyond 255Tbps and will be the Next Generation Internet beyond 5G which the secret lies in the media to facilitate this transmission.
How did the researchers at Eindhoven University of Technology (TU/e) and University of Central Florida (CREOL) do it? Multi-core fiber, of course! As it stands, the entire internet backbone consists of single-mode glass and plastic fiber. These fibers can only carry one mode of light — which, in essence, means they can only carry the light from a single laser. (It’s a bit more complex than that, but it’s beyond the scope of this story to explain it any further.) You can still use wavelength division multiplexing (WDM) to push insane amounts of data down a single fiber (a few terabits), but we will eventually run up against the laws of physics.
Multi-core fiber — literally a strand of optical fiber that has multiple cores running along it — allows for multi-mode operation. It has historically been hard (and costly) to make high-quality multi-mode fiber, but it seems those barriers are finally starting to fall. In this case, the TU/e and CREOL researchers used a glass fiber with seven individual cores, arranged in a hexagon. They used spatial multiplexing to hit 5.1 terabits per carrier, and then WDM to squeeze 50 carriers down the seven cores — for a total of 255Tbps. This wasn’t just a short-range laboratory demo, either: The multi-mode fiber link was one kilometer (0.62 miles) long. [Research paper: doi:10.1038/nphoton.2014.243]
(The image at the top of this story is DARPA’s multi-core photonic-bandgap fiber — not the seven-core fiber used in the research discussed here.)
Eventually, multi-mode fiber will most likely replace the internet’s current single-mode backbone — but considering such an upgrade would require millions of miles of new multi-core cabling, and lots of new routing hardware to handle the multi-mode connections, we’re talking very long-term here. Still, with internet traffic continuing to grow at an alarming rate — mostly fueled by the popularity of streaming video, and smartphones and tablets bringing billions more people online — it’s nice to know that we now have the necessary technology to make sure that we don’t run out of bandwidth any time soon.
