BT and Toshiba Demo Secure UK Quantum Communications

13th October, 2016 (6 Comments)

Telecoms giant BT and Japanese electronics firm Toshiba have today teamed-up to demonstrate the future of secure data communication via quantum cryptography, which works by delivering secret keys over fibre optic cables via the “smallest possible packets of light.”

WiFi Needs 1280MHz of 5GHz Spectrum for “Whole Home” 1Gbps Speed

4th October, 2016 (0 Comments)

A recent study from Qualcomm Technologies has concluded that home WiFi (WLAN) wireless networks will need more than double the current amount of radio spectrum (around the 5GHz band) to deliver “sustained” speeds of 1Gbps (1000Mbps+) throughout an entire home.

AT&T Labs Propose AirGig Wireless Powerline Broadband Technology

23rd September, 2016 (9 Comments)

The research and development division of global telecoms giant AT&T has begun to develop a new twist on the old Powerline Communications idea, but instead of sending electrical signals over the national grid’s power cables it would use the cables to “guide” a wireless broadband transmission.

Scientists Successfully Push Fibre Optic Transmissions Close to the Limit

19th September, 2016 (3 Comments)

A joint team of researchers working for Nokia Bell Labs, Deutsche Telekom T-Labs and the Technical University of Munich in Germany has successfully used a new technology to push 1Tbps of real-world data transfer over a pure fibre optic cable to hit close to its theoretical maximum (The Shannon Limit).

Scientists Demo MegaMIMO 2.0 for 3 x Faster WiFi and Mobile Broadband

25th August, 2016 (0 Comments)

Researchers working at the Massachusetts Institute of Technology (MIT) have developed a more efficient way of coordinating multiple wireless broadband routers at the same time by using their new MegaMIMO 2.0 technology, which could deliver three times faster WiFi speeds and double the range.

World Record – Scientists Send 6Gbps of E Band Wireless Data Over 37km

24th May, 2016 (6 Comments)

A team of German scientists have successfully achieved a record data rate of 6Gbps (Gigabits per second) over a distance of 36.7 kilometres by harnessing part of the E band spectrum, which operates at a radio frequency of 71-76GHz (GigaHertz). The new development could be used to boost both terrestrial and Satellite broadband capacity links.

Researchers in Scotland Promise Self Healing 5G Mobile Networks

30th March, 2016 (0 Comments)

Future 5G based Mobile Broadband networks are expected to be extremely fast (peak speeds of up to 10Gbps), but new EU supported research taking place at the University of West of Scotland (UWS) could also make them “self-healing” to boost performance, protect against DDoS attacks and recover faster from outages.

10Gbps Capable 5G Mobile Broadband Could Arrive as Soon as 2017

23rd February, 2016 (5 Comments)

Most EU and UK telecoms regulators don’t expect the first commercial roll-out of future 5G capable Mobile Broadband services to happen until 2020 or later, but that hasn’t stopped Nokia and Verizon aiming for it to be launched far sooner.. in 2017! Field trials have already begun.

UK Scientists Squeeze 1.125Tbps Through a Single Fibre Optic Receiver

12th February, 2016 (3 Comments)

A team of researchers working out of the University College London have given fibre optic communications technology a further boost by achieving the highest data throughput ever reported (1.125 Terabits per second) for a single coherent optical receiver.

Japanese Scientists Push 100Gbps Wireless Broadband Using 300GHz

11th February, 2016 (4 Comments)

Last week we reported that Japanese scientists had managed to build a wireless network that could send data at a speed of 56Gbps (Gigabits per second) using the 72-100GHz (GigaHertz) radio frequency bands (here) and now another team claims it can hit 100Gbps by pushing into the TeraHertz (300GHz+).

Scientists in Japan Test 56Gbps Wireless Chip to Replace Fibre Optic Lines

3rd February, 2016 (1 Comment)

Japanese scientists have demonstrated (lab test) a new low power CMOS wireless transceiver chip that can deliver data speeds of 56Gbps (Gigabits per second), which could be used by mobile operators to replace expensive fibre optic cables to their base stations. But there’s a catch.. distance.

Li-Fi LED Light Network Delivers 1GBps Speeds in Commercial Pilot

25th November, 2015 (4 Comments)

It’s been a long time coming but the new Light Fidelity (LiFi) technology, which can turn LED (Light-Emitting Diode) based home and office lighting or display systems into a sophisticated wireless communications network like WiFi, has finally started to reach the commercial pilot phase.

BT and Alcatel-Lucent Hit 5600Mbps Broadband Using XG-FAST Tech

20th October, 2015 (61 Comments)

Forget BT’s plan to deploy “ultrafast” 300-500Mbps capable G.fast broadband technology to 10 million UK premises by 2020 (here). Today the operator has joined with Alcatel-Lucent to test future XG.FAST (G.fast2) technology, which under lab conditions has just pushed aggregate speeds of 5.6Gbps over 35 metres of copper cable.

“Danger Will Robinson” – Internet Capacity Crunch in 8 Years Time

21st September, 2015 (9 Comments)

Professor Andrew Ellis of Aston University’s School of Engineering and Applied Science has once again warned that the Internet “could be on the brink … of a capacity crunch“, which might force ISPs to throttle your broadband and it could happen within the next 8 years. Best get that tinfoil hat.

Scientists Have Broken One of the Biggest Limits in Fibre Optic Networks

28th June, 2015 (6 Comments)

One of the biggest limitations in ultrafast fibre optic communications is that even optical signals can weaken over long distances, which requires expensive electronic regenerators (repeaters) to be placed along the route to boost the signal. But what if you didn’t need those? Future networks could be both faster and cheaper.
