ITU Standard Could Make Fast Home VLC Visible Light Networks a Reality

22nd January, 2019 (19 Comments)

The International Telecommunication Union is close to giving its final approval to a new standard (G.9991 / G.vlc), which could finally help to turn secure high-speed indoor Visible Light Communication (VLC / LiFi) networks into something that you can buy instead of WiFi.

ITU Touts Low Cost Fibre Optic Cable for Rural DIY Broadband Builds

12th January, 2019 (6 Comments)

A series of new ITU standards promise to help encourage the ‘Do-It-Yourself‘ generation to build their own Terabit capable remote broadband networks. The standards propose a cheap, tough and lightweight optical fibre cable that can be laid on the grounds surface, underwater, aerially or shallow buried with hand tools.

5G Mobile Trial in Japan Delivers Broadband Speeds of 27Gbps

22nd November, 2018 (3 Comments)

A joint outdoor field trial by Mitsubishi and NTT DOCOMO in Japan appears to have achieved a “world’s first” by pushing the future 5G mobile network technology to deliver maximum throughput speeds of 27Gbps and 25Gbps (communication distances of 10m and 100m respectively) via one mobile terminal in the 28GHz band.

RIP Sir Charles Kuen Kao – The Father of Fibre Optic Technology

24th September, 2018 (2 Comments)

We’re saddened to report that Nobel Prize winner Sir Charles Kuen Kao (aka – “Father of Fibre Optics“), whom was jointly awarded the 2009 Nobel Prize in Physics for “ground-breaking achievements concerning the transmission of light in fibres for optical communication“, passed away yesterday at 11:45am in Hong Kong.

Does Having Fast UK Broadband Mean You Lose More Sleep? Hmm

8th August, 2018 (7 Comments)

A recently published study from researchers at the University of Pittsburgh (USA) and Bocconi University (Italy) attempts to “identify the causal impacts” of “high-speed internet” on sleep duration and sleep satisfaction. The results, they claim, suggest that those with good broadband tend to sleep 25 minutes less than those without.

Scientists Stuff 661Tbps Down a Single Optic Fibre at High Efficiency

3rd August, 2018 (23 Comments)

A team of scientists from Japan and the EU have found a way to replace the use of many parallel lasers with a single frequency comb source, which has enabled them to push data at a speed of 661Tbps (Terabits per second) down a single-mode 30 core optical fibre cable.

Rising Sea Levels Put Submarine Fibre Optic Cables At Risk – No Really

18th July, 2018 (1 Comment)

New research from the University of Wisconsin-Madison has warned that rising sea levels will soon threaten the land-based stations for undersea fibre optic cables, as well as data centres and other vital international telecoms infrastructure situated in or around low lying coastal areas.

Scientists Use Fibre Optic Broadband Cables to Detect Earthquakes

5th July, 2018 (0 Comments)

Underground optical fibre networks aren’t just brilliant at delivering ultrafast broadband ISP speeds to UK homes. A team of German scientists have found that they can also be used to detect Earthquakes, as well as other seismic signals from hammer shots, passing cars or wave movements in the ocean.

Dr John Cioffi on the Viability of 1 Terabit DSL Copper Line Broadband

18th June, 2018 (34 Comments)

Broadband ISP speeds of 1 Terabit per second (1000000Mbps) down a traditional copper line? It may sound impossible but that’s what Dr John Cioffi, best known as the “father” of DSL, proposed last year (here) with Terabit DSL technology. In our latest interview we ask John about TDSL’s viability.

BT Build’s First Quantum-Secured 500Gbps UK Fibre Optic Network

12th June, 2018 (6 Comments)

BT claims to have built the UK’s “first practical quantum-secured high-speed fibre network“, which harnesses quantum encryption and can transfer data at a speed of 500Gbps (Gigabits per second). The network runs over a distance of 120km via multiple exchanges between BT Labs in Ipswich and Cambridge University.

VVC Standard Could Shrink 4K Video Streams to Fit Slow Broadband Lines

30th April, 2018 (7 Comments)

A future video standard called Versatile Video Coding (VVC), which could potentially make it possible to squeeze a high quality 4K (3840 x 2160 pixels) video stream down a fairly slow broadband ISP line, is in the early stages of development at the International Telecommunication Union (ITU).

Scientists Learn from ADSL to Boost Fibre Optic Broadband Speeds

24th April, 2018 (4 Comments)

A team of Dutch scientists from the Eindhoven University of Technology (TU/e) have borrowed a technology from existing copper based ADSL and VDSL (FTTC) networks in order to boost speeds over pure fibre optic (FTTH/P) lines, such as by implementing adaptive modulation techniques.

UK ISP Experiment Gets ADSL Broadband to Work Over Wet String

13th December, 2017 (22 Comments)

The engineers at AAISP (Andrews and Arnold) look to have become contenders for the oddball experiment of the day award after they successfully made an ADSL based broadband connection “work” over 2 metres of wet string (at the surprisingly quick pace of 3.5Mbps), as opposed to the usual metallic wiring.

Scientists Boost Home WiFi Signals via DIY 3D Printed Reflectors

13th November, 2017 (2 Comments)

A new study from a team of researchers working out of Dartmouth College, and the Universities of Washington, Irvine and Columbia in the USA, has demonstrated how it’s possible to easily build a low-cost 3D printed reflector that can be used to improve your home WiFi wireless network signals.

Twisted Light Wireless Optical Broadband Could Make Fibre Optics Obsolete

31st October, 2017 (5 Comments)

A team of scientists working in the Photonics Research Group at the University of Glasgow (Scotland) has made progress on a way to adapt twisted light across a wireless optical (laser) ultrafast broadband network, which they claim could make traditional fibre optic (FTTH/P) cables “obsolete.”

UPDATE Openreach Prep Second FTTC Broadband Spectrum Refarming Test

19th October, 2017 (8 Comments)

Openreach (BT) has announced that they are to conduct a second Proof of Concept (PoC) trial of “Spectrum Refarming” technology, which in theory could result in a boost to broadband speeds by allowing different technologies (e.g. FTTC / VDSL2 and G.fast) to share the same spectrum frequency.

19th October, 2017 (0 Comments)

Scientists working out of the Optical Networks Group at University College London have developed a cheaper and simpler receiver for optical “full fibre” (FTTH/P) broadband networks, which makes it possible to dedicate a wavelength of light to each subscriber and “avoid bandwidth sharing.”
