Submission + - TP-Link Launch First 802.11ad Equipped Wi-Fi Router (4.6Gbps via 60GHz)

Mark.JUK writes: Networking equipment manufacturer TP-Link are today claiming a "world's first" after they unveiled their new Talon AD7200 router, which uses the cutting edge 802.11ad Wi-Fi standard (Qualcomm Atheros chipset) in order to deliver Wireless LAN (WLAN) data speeds of up to 4,600 Megabits per second via the unlicensed 60GHz spectrum band. Mind you the limited range and problematic penetration of solid walls at 60GHz might make it less useful in some homes.

Submission + - World's First 5G Field Trial Delivers Speeds of 3.6Gbps Using sub-6GHz

Mark.JUK writes: Global Chinese ICT firm Huawei and Japanese mobile giant NTT DOCOMO today claim to have conducted the world's first large-scale field trial of future 5th generation (5G) mobile broadband technology, which was able to deliver a peak speed of 3.6Gbps (Gigabits per second).

Previous trials have used significantly higher frequency bands (e.g. 20-80GHz), which struggle with coverage and penetration through physical objects. By comparison Huawei's network operates in the sub-6GHz frequency band and made use of several new technologies, such as Multi-User MIMO (concurrent connectivity of 24 user devices in the macro-cell environment), Sparse Code Multiple Access (SCMA) and Filtered OFDM (F-OFDM).

Assuming all goes well then Huawei hopes to begin a proper pilot in 2018, with interoperability testing being completed during 2019 and then a commercial launch to follow in 2020. But of course they're not the only team trying to develop a 5G solution.

Submission + - Scientists Overcome One of the Biggest Limits in Fibre Optic Networks (

Mark.JUK writes: Researchers at the University of California in San Diego have demonstrated a way of boosting transmissions over long distance fibre optic cables and removing crosstalk interference, which would mean no more need for expensive electronic regenerators (repeaters) to keep the signal stable. The result could be faster and cheaper networks, especially on long-distance international subsea cables.

The feat was achieved by employing a frequency comb, which acts a bit like a concert conductor; the person responsible for tuning multiple instruments in an orchestra to the same pitch at the beginning of a concert. The comb was used to synchronize the frequency variations of the different streams of optical information (optical carriers) and thus compensate in advance for the crosstalk interference, which could also then be removed.

As a result the team were able to boost the power of their transmission some 20 fold and push data over a “record-breaking” 12,000km (7,400 miles) long fibre optic cable. The data was still intact at the other end and all of this was achieved without using repeaters and by only needing standard amplifiers.

Submission + - The Tiny Camera and Sensors Powered by Stealing from Your WiFi Signals

Mark.JUK writes: A team of scientists working at the University of Washington have demonstrated a tiny camera, battery charger and sensors that can be parasitically powered by stealing electricity from ordinary home WiFi transmissions (at least 300mV of sustained electricity was needed via a DC–DC converter with the lowest threshold) operating in the 2.4GHz band over multiple channels.

The PoWiFi system could in the future also be adapted to suck energy from different bands (e.g. 900MHz, 5GHz etc.) to further improve its capabilities, although doing so could create some interesting new legal questions and or pose some new security risks (e.g. a Power Denial-of-Service Attack).

Submission + - Nokia Networks Demonstrates 5G Mobile Speeds Running at 10Gbps via 73GHz (

Mark.JUK writes: The Brooklyn 5G Summit appears to have provided a platform for Nokia Networks to demo a prototype of their future 5G (5th Generation) mobile network technology, which they claim can already deliver data speeds of 10 Gigabits per second using millimeter Wave (mmW) frequency bands of 73GHz (7300MHz).

The demo also made use of 2×2 Multiple-Input and Multiple-Output (MIMO) links via single carrier Null Cyclic Prefix modulation and frame size of 100 micro seconds, although crucially no information about the distance of this demo transmission has been released and at 73GHz you'd need quite a dense network in order to overcome the problems of high frequency signal coverage and penetration.

Submission + - UK Scientists Claim 1Tbps Data Speed via Experimental 5G Technology

Mark.JUK writes: A team of Scientists working at the University of Surrey in England claim to have achieved, via an experimental lab test, performance of 1Tbps (Terabit per second) over their candidate for a future 5G Mobile Broadband technology. Sadly the specifics of the test are somewhat unclear, although it's claimed that the performance was delivered by using 100MHz of radio spectrum bandwidth over a distance of 100 metres.

The team, which forms part of the UK Government's 5G Innovation Centre, is supported by most of the country's major mobile operators as well as BT, Samsung, Fujitsu, Huawei, the BBC and various other big names in telecoms, media and mobile infrastructure. Apparently the plan is to take the technology outside of the lab for testing between 2016 and 2017, which would be followed by a public demo in early 2018.

In the meantime 5G solutions are still being developed, with most in the early experimental stages, by various different teams around the world. Few anticipate a commercial deployment happening before 2020 and we’re still a long way from even defining the necessary standard.

Submission + - BT Unveils 1000Mbps Capable Broadband Rollout for the United Kingdom

Mark.JUK writes: The national telecoms operator for the United Kingdom, BT, has today announced that it will begin a country-wide deployment of the next generation hybrid-fibre (ITU G.9701) broadband technology from 2016/17, with most homes being told to expect speeds of up to 500Mbps (Megabits per second) and a premium service offering 1000Mbps will also be available.

At present BT already covers most of the UK with hybrid Fibre-to-the-Cabinet (FTTC) technology, which delivers download speeds of up to 80Mbps by running a fibre optic cable to a local street cabinet and then using VDSL2 over the remaining copper line from the cabinet to homes. follows a similar principal, but it brings the fibre optic cable even closer to homes (often by installing smaller remote nodes on telegraph poles) and uses more radio spectrum (17-106MHz) over a shorter remaining run of copper cable (ideally less than 250 metres).

The reliance upon copper cable means that the real-world speeds for some, such as those living furthest away from the remote nodes, will probably struggle to match up to BT’s claims. Never the less many telecoms operators see this as being a more cost effective approach to broadband than deploying a pure fibre optic / Fibre-to-the-Home (FTTH) network.

Submission + - TWEETHER Project Promises 10Gbps mmW 92-95GHz Based Wireless Broadband ( 1

Mark.JUK writes: A new project called TWEETHER, which is funded by Europe's Horizon 2020 programme, has been setup at Lancaster University (England) with the goal of harnessing the millimetre wave (mmW) radio spectrum (specifically 92-95GHz) in order to deploy a new Point to Multipoint wireless broadband technology that could deliver peak capacity of up to 10Gbps (Gigabits per second). The technology will take 3 years to develop and is expected to help support future 5G based Mobile Broadband networks.

Submission + - Scientists Build 7 Core Fibre Optic Cable for Record Speeds of 255 Tbps

Mark.JUK writes: A team of researchers at the Eindhoven University of Technology (Netherlands) have built a new fibre optic cable with seven cores, which when combined with wavelength division multiplexing (i.e. harnessing the different colors of laser light to carry data) has enabled them to deliver a transmission speed of 255 Terabits per second (Tbps) over a single 1km long link.

Submission + - Samsung Achieve Outdoor 5G Mobile Broadband Speed of 7.5Gbps

Mark.JUK writes: Samsung has successfully become the first to demonstrate a future 5G mobile network running at speeds of 7.5Gbps (Gigabits per second) in a stationary outdoor environment, but to cap that achievement off they also delivered 1.2Gbps while using the same technology and driving around a 4.3km long race track at speeds of up to 110Kph.

Crucially the test was run using the 28GHz radio spectrum band, which ordinarily wouldn't be much good for mobile networks where wide coverage and wall penetration is an important requirement. But Samsung claims it can mitigate at least some of that by harnessing the latest Hybrid Adaptive Array Technology (HAAT), which uses millimeter wave frequency bands to enable the use of higher frequencies over greater distances.

Several companies are competing to develop the first 5G technologies, although consumers aren't expected to see related services until 2020 at the earliest.

Submission + - BT and Huawei Push 3Tbps Down Existing 359km Commercial Fibre Optic Link

Mark.JUK writes: The United Kingdom's national telecoms operator, BT, has teamed up with Chinese IT firm Huawei to push data speeds of 3Tbps (Terabits per second) over an existing real-world 359km long fibre optic link by harnessing a "record spectral efficiency" of 5.97bit/s/Hz and commercial grade hardware and software.

The real-time 3Tbps super channel comprised of 15 x 200Gbps (16-QAM) sub channels, bundled together to provide combined capacity, and these were separated by as little as 33.5GHz in order to achieve the claimed spectral efficiency. In the future such connections could help to feed the ever rising capacity demands of mobile operators and ISPs, which are themselves attempting to cater for growing consumer broadband usage and ideally without having to build expensive new fibre optic links.

Submission + - "Word Record" as Single Laser and Fibre Optic Cable Delivers 43 Tbps

Mark.JUK writes: A research group working out of the Technical University of Denmark claims to have broken "another world record" in fibre optic data transfers after they were able to demonstrate speeds of 43 Terabits per second over a single laser and fibre optic cable (67km long), which is theoretically much closer to real-world connections than most other lab tests where multiple lasers and cables can be used.

Professor Leif Oxenløwe of DTU Fotonik said that his team had "used all the known, neat tricks that exist nowadays to make data in five dimensions: time, frequency, polarization, quadrature and space”. However one such "neat trick" is the decision not to use a traditional single core cable and to instead adopt a 7 core (glass threads) design from Japanese telecoms firm NNT.

Admittedly the new fibre optic cable does not take up any more space than the standard single-core version, but it's still a new cable and thus perhaps the "world record" claims aren't quite comparing apples to apples.

Submission + - Alcatel-Lucent's XG-FAST Pushes 10,000Mbps over Copper Phone Lines

Mark.JUK writes: The Bell Labs R&D division of telecoms giant Alcatel-Lucent has today claimed to set a new world record after they successfully pushed "ultra-broadband" speeds of 10,000 Megabits per second (Mbps) down a traditional copper telephone line using XG-FAST technology, which is an extension of (ITU G.9700). is a hybrid-fibre technology, which is designed to deliver Internet speeds of up to 1000Mbps over shorter runs of copper cable (up to around 250 meters via 106MHz+ of radio spectrum). The idea is that a fibre optic cable is taken closer to homes and then works to deliver the last few metres of service, which saves money because the operator doesn't have to big up your garden to lay new cables.

By comparison XG-FAST works in a similar way but via an even shorter run of copper and using frequencies of up to 500MHz. For example, XG-FAST delivered its top speed of 10,000Mbps by bonding two copper lines together over just 30 metres of cable. But this might be a problem for commercial operators, which will want to maximise profits by using more copper to reach more homes and not less.

Submission + - EU Consumers Expected to Demand 165Mbps Broadband by 2020

Mark.JUK writes: Cable Europe, the official trade association for cable telecoms and TV operators across the continent, has published a new study with cable ISP NL Kabel that claims to predict that consumers will be demanding average broadband download speeds of 165Mbps (Megabits per second), with uploads of 20Mbps, by the year 2020. At an extreme around 2% of all users are also predicted to demand 1000Mbps (1 Gigabit per second).

The research is based off a "quantitative model", which was designed by a team working out of the Technical University of Eindhoven and Dialogic to predict demand for Internet speeds in the coming years. But equally some might view it as a piece of self-serving research by those parties with an interest in cable and one that conflicts with other studies. What a person "needs" remains very much subjective, balanced against how they use the technology and their expectations.

Submission + - Aston University to Halt World Fibre Optic Internet "Capacity Crunch" with PEACE

Mark.JUK writes: A team of international scientists working out of Aston University in England have pledged to tackle the pending Internet "capacity crunch" in major fibre optic networks through a new GBP1.5 million project called Petabit Energy Aware Capacity Enhancement (PEACE), which aims to "significantly" improve bandwidth and reduce energy consumption on related networks by mitigating the signal distortion that exists in existing cables.

According to Professor Ellis of Aston's Institute for Photonic Technologies, related signals "have been amplified to such an extent that they are now more intense than sunlight at the surface of the Earth’s atmosphere" and this causes the distortion. But PEACE intends to tackle this by using a balance of digital, analogue electronic and optical processing to halve the energy consumption of optical transponders and boost bandwidth.

"We will increase network capacity by maximising spectral use, and developing techniques to combat the nonlinear effects induced by the high intensities encountered in today’s networks," said Professor Ellis.
