The great ambition of the networked society is to connect everything, everywhere, all the time. But the ideal of seamless communications poses fundamental challenges to legacy networks that the new 5G communication networks currently under development need to solve. One of such challenges is supporting the significant growth of traffic demands. Next generation services such as mobile cloud service, gaming, social-networking applications and 3D immersive applications require massive capacity and higher data rates than current 4G networks are unable to sustain. In the framework of the mmMAGIC2 5GPPP European research project, researchers at IMDEA Networks3 in collaboration with 18 partner organizations, have developed and designed a new mobile radio access technology for deployment in mm-wave frequencies, a highly promising candidate solution for efficient high capacity data delivery.

Millimeter-wave (mm-wave) systems exploit frequencies above 10 GHz. Communications at such high frequencies pose unique challenges. On the one hand, mm-wave systems achieve data rates that are orders of magnitude higher than current systems operating at lower frequencies. On the other hand, mm-wave links experience high variability in channel quality due to high propagation loss and unfavorable atmospheric absorption. Hence, the fundamental question the mmMAGIC project aimed to answer is: how can we efficiently overcome the challenges and benefit from the potential gains arising from the use of mm-wave frequencies? The mmMAGIC solution is a new radio system concept for mobile broadband communications targeting operation in wide-contiguous bands in mm-wave frequencies. The new radio is a ready-to-use solution that meets the anticipated end-user and traffic demands of the networked society in the 2020 time-frame and addresses the specific challenges of mm-wave bands.

In particular, the new radio concept takes advantage of novel channel models proposed in the framework of the project and provides a new antenna design with hybrid beamforming capabilities. The antenna design addresses important practical constraints for real deployment, such as antenna size, cost and complexity. The validity of the system design has been corroborated by hardware-in-the-loop experiments, showing its effectiveness under real channel conditions and with actual hardware. Within the mmMAGIC project, conceptual enablers that will compose the new mm-wave 5G architecture have been identified and assessed. In addition to the enablers, radio access network and transport functionalities for network integration of mm-wave radio access technology have been introduced. Within the former category, a predictive beam-steering approach has been proposed to improve performance of mm-wave links and relieve part of the time burden caused by beam training procedures. The approach exploits history information about the users’ movement patterns and can also be employed for accurate indoor localization systems.

mmMAGIC was an industry-driven project, bringing together major infrastructure vendors (Samsung, Ericsson, Alcatel-Lucent, Huawei, Intel, Nokia), major European operators (Orange, Telefonica), leading research institutes and universities (Fraunhofer HHI, CEA LETI, IMDEA Networks, Universities Aalto, Bristol, Chalmers and Dresden), measurement equipment vendors (Keysight Technologies, Rohde & Schwarz) and one SME (Qamcom). The project operated from June 2015 to June 2017.

Better broadband coming to 7 Vermont towns thanks to grants

MONTPELIER, Vt. (AP) — People in seven rural Vermont communities will be getting better broadband internet service thanks to a series of grants through Connectivity Initiative distributed by the Department of Public Service. The Connectivity Initiative works to expand high-speed broadband service starting with unserved and underserved locations. ECFiber is getting $72,500 to bring fiber optic cable service to 31 homes and businesses in the towns of Randolph, Royalton and Stockbridge.

Consolidated Communications Inc. received $175,000 to expand broadband to 162 homes and businesses in Reading, Woodstock and Whitingham. Comcast received a grant of $300,000 to bring cable broadband service to 114 homes and businesses in Cavendish.

The areas of Wales with the slowest broadband speeds revealed

A major study has revealed the areas of Wales with the slowest broadband speeds. The map below shows the areas worst served by broadband connections in the lightest colours. Wales has some of the slowest speeds of any part of the UK.

Four of the 10 constituencies with the slowest download speeds in the UK are in Wales, with Carmarthen East and Dinefwr in the top position. This is based on Which? consumer-tested broadband speeds.

This is the UK table of shame, dominated by Wales and Scotland:

The Areas Of Wales With The Slowest Broadband Speeds Revealed Carmarthenshire

1. Carmarthen and Dinefwr

2. Ross, Sky and Lochaber

3. Na h-Eilanan an Iar

4. Orkney and Shetland

5.

Argyll and Bute

6. North Herefordshire

7. Montgomeryshire

8. Brecon and Radnorshire

9. Caithness, Sutherland and Easter Ross

10. Ceredigion

There were another three Welsh constituencies in the worst 20 for broadband speeds, Carmarthen West and South Pembrokeshire (15th) and Monmouth (19th).

How the study worked

The Areas Of Wales With The Slowest Broadband Speeds Revealed

The researchers for the British Infrastructure Group (BIG)1 also looked at the total number of broadband connections in the constituency. They they used Ofcom data at how many of them had connections of above 10 MB/s (million bits per second) or 24 MB/s.

Families who want to have a number of members watching videos, listening to music or playing games at the same time are advised they would need speeds of around 24 MB/s to avoid problems. Anything below 10 MB/s would be insufficient to reliably stream videos even for a single user. The researchers found that 6.7m UK broadband connections didn’t even reach 10 MB/s and only 40.8% achieved over 24 MB/s.

The constituencies with the least substandard broadband

Governments must ‘stop passing the buck’

More than 50 MPs from across the party divides have come together to press for action amid concern that nearly seven million connections may not deliver the proposed minimum standard.

Dwyfor Meirionnydd Plaid Cymru MP Liz Saville Roberts, one of the supporters of the report, said: “Far too many people across Wales are unable to access what Ofcom recognises as the speed required for basic tasks such as web browsing, streaming and video calling, and this digital divide undoubtedly contributes to the wider economic divide, depressing wages and living standards. The British Government and the Welsh Government must stop passing the buck and commit to connecting the whole of Wales with ultra-fast broadband.”

It is understood that less than half of all UK connections receive superfast speeds of 24 Mb/s. The MPs say it is “almost impossible” to determine how many households do not receive the speeds set out in their contracts.

Lack of access is ‘stifling the potential of local business’

The Areas Of Wales With The Slowest Broadband Speeds Revealed Newly elected Gower MP Tonia Antoniazzi

Gower Labour MP Tonia Antoniazzi, another supporter of the report, said: “Access to fast broadband is a fundamental requirement for rural economies to thrive. Gower continues to lack consistent connectivity across the constituency, this includes mobile coverage.

“Gower is home to a mix of micro and small and medium businesses, from creative industries to food production. It is essential for my constituents and their businesses to be served with high quality broadband and mobile coverage.

“There are 7,408 broadband connections in Gower not meeting the basic minimum download speed. This is a matter which the UK Government and providers must address immediately.

“I fear lack of access to decent broadband is stifling the potential of local business and preventing growth within the region.”

Grant Shapps, the former Conservative chairman who chairs the group, said: “Although broadband is increasingly considered to be an essential utility, the quality of customer services has simply not caught up with demand. It is unacceptable that there are still no minimum standards in the UK telecoms sector to protect customers from protracted complaints procedures, and ensure that broadband providers are fully accountable to their customers.”

The MPs say it is “unacceptable” Ofcom has not considered automatic compensation for households that consistently get a poor service below what they are paying for.

Governments have ‘dragged their heels for too long’

The Areas Of Wales With The Slowest Broadband Speeds Revealed Ceredigion Plaid Cymru MP Ben Lake

Ceredigion Plaid Cymru MP, Ben Lake, one of the backers of the report, said: “Poor broadband speed, as well as poor mobile data signal not only impacts on residents but on businesses who are unable to reach beyond their local areas.

“Digital connectivity simply isn’t good enough in Ceredigion and in many other parts of Wales and the result is our rural communities are being cut off.

“Whilst businesses in cities such as Cardiff could feasibly rely on passing trade, rural areas have to go beyond their local high street. It is vital that we ensure businesses, and every resident in Wales, including rural Wales, have access to high-speed broadband and mobile data signal. Westminster and the Welsh Government have dragged their heels for too long – we’ve waited long enough.”

This year’s Digital Economy Act set out a so-called universal service obligation across the country, which defined a minimum broadband download speed of 10 Mb/s.

This is what the Welsh Government is doing:

The Areas Of Wales With The Slowest Broadband Speeds Revealed The Welsh Government insists it is making progress on broadband

A Welsh Government spokeswoman said: “There has been tremendous progress in the availability of superfast broadband across the country thanks to the work of the Welsh Government. Over 647,000 premises can now access it in Wales as a result of the Welsh Government’s Superfast Cymru programme.

“The latest Ofcom report shows that Wales has the highest availability of superfast broadband among the devolved nations, largely thanks to the Superfast Cymru programme, with eight out of 10 premises with access. This compares with just over half in 2014.

“Areas such as Gwynedd, Conwy and Anglesey would have no access to superfast broadband without the intervention of Superfast Cymru. Now, for example, over 49,000 premises in Gwynedd can access it…

“We know there is more to do to reach the final premises including those not part of the Superfast Cymru rollout, and we are already looking at how to do this. We’ve recently announced potential funding of ?80m to reach the small percentage of premises not part of the Superfast Cymru project or commercial rollout.

“Once superfast broadband has been made available people will not receive it automatically. If they wish to receive it they will need to contact their internet service provider in order to change their package so that they can receive the faster speeds.

“Our Access Broadband Cymru scheme can also offer assistance to those currently not able to access superfast broadband by providing grant aid to receive it through other technologies.”
