BT claims big broadband speed boost

Written By Unknown on Kamis, 25 September 2014 | 23.34

25 September 2014 Last updated at 12:52

BT is claiming to have made a "big breakthrough" with fibre broadband, which could see homes and businesses see speeds rise to 1Gbps (gigabit per second).

A trial of so-called G-Fast technology has managed download speeds of 800Mbps (megabits) and upload speeds of 200Mbps.

The trial is significant because it utilises existing technology.

BT has been criticised for its continued use of copper lines.

So-called Fibre to the Cabinet (FTTC), which uses a combination of fibre and copper lines, is BT's preferred technology for broadband rollout.

It is significantly slower than Fibre to the Premises technology (FTTP) but is much cheaper to deploy.

FTTC also gets slower over distance because it relies on copper for the last part of the connection.

It means homes that are further away from BT's green street cabinets will have slower speeds.

BT claims that the new technology can achieve good speeds over longer lines of 66m (216ft), which it said encompasses 80% of connections.

G-Fast technology has been tested at BT's research laboratory at Adastral Park in Ipswich. It is due to open a new ultrafast broadband lab where it will continue to test its potential.

BT said commercial equipment could be available from manufacturers by December 2015, but the company has made no decisions about rolling the technology out yet.

The new technology could also be useful to businesses which currently rely on dedicated lines that run on ethernet.

"We see G-Fast as a very promising technology with significant potential," said Dr Tim Whitley, managing director of research at BT.

"BT has a long history of pushing the boundaries in telecommunications, from the earliest days of the electric telegraph to today's global fibre networks, and it's crucial that we stay ahead of the curve for the benefit of our customers and shareholders."

Rival Virgin Media is also experimenting with new ways to boost speed - including a trial in a Cambridgeshire village, using narrow-trenching.

The method means engineers can lay the cable faster and the trial to 100 houses in the area achieved 1Gb speeds.

Need for speed

Ovum analyst Matthew Howett thinks the technology could be beneficial to both consumers and businesses.

"Given the huge costs involved in a full fibre solution, and the challenging economic environment, it's important to make the most of, and extend the life of technologies already deployed - in the most cost effective way," he said.

"This should result in quicker wins for consumers and businesses at a favourable price."

The debate about how much speed consumers and businesses need has grown louder in recent months.

The Federation of Small Businesses (FSB) recently said that the government's target to have superfast speeds of at least 24Mbps in 90% of homes by 2017 lacked ambition and needed a rethink.

It called for a minimum of 100Mbps by 2030.

Labour has also jumped on the speed bandwagon and pledged to increase broadband speeds if it wins the next election.

Blackberry rethinks the keyboard

WATCH: Rory Cellan-Jones tries out the Blackberry Passport

Blackberry has launched a distinctive handset featuring a square screen and a keyboard that offers both physical keys and touch-enabled gesture controls.

It said work-focused users in particular should benefit from the Blackberry Passport's innovations.

Sales of the company's handsets - which are powered by its own operating system - have been in decline.

Analysts said the new device should appeal to existing Blackberry owners but might struggle to win over others.

The Canadian company's chief operating officer said the handset's release was part of a broader turnaround strategy led by John Chen, who became chief executive in November.

"You're going to see us be very focused," Marty Beard told the BBC.

"Potentially, in the past we got a little too broad a little too aggressively.

"Our target segment is more enterprise-focused. It's the power professional. It's someone who wants to be productive.

"Those users tend to be in regulated industries like banking or healthcare or government. We know those segments really well - in a way it's getting back to the Blackberry roots."

Push and swipe

The Passport got its name because its dimensions resemble a thick version of the travel document.

It has a 4.5in (11.4cm) touchscreen with a resolution of 453 pixels per inch - higher than Apple's iPhone 6 Plus, but lower than Samsung's Galaxy Note 4.

Blackberry suggests documents are easier to edit because of the extra width provided by having a square screen, even if it is less suited for watching video.

The keyboard buttons are also touch-sensitive. This allows gesture-based shortcuts that were previously restricted to Blackberry's all-screen devices.

For example, swiping a finger quickly leftwards along the keys deletes the previous word, while sliding a thumb along them more slowly moves the cursor in the same direction.

In addition, users can select from three anticipated words - shown near the bottom of the screen - by flicking upwards beneath the desired one. This saves having to type the text in full.

"In some cases it takes a while to learn it, because even if you're familiar with a Blackberry it's a little bit different because it's that combination of physical plus virtual," acknowledged Mr Beard.

"So there may be that learning curve in the beginning, but it's well worth it, and once people learn it they are flying."

One expert who has tested the handset supported the claim.

"It certainly made me respond more eloquently to emails rather than just triaging them with a 'Yes, no, I'll call you back or see you later'," said Shaun Collins, founder of the telecoms consultancy CCS Insight.

"However, it's going to divide opinion - it gives you the Blackberry experience on steroids. But for a broader audience it will be a curiosity."

The phone is being sold at an "introductory rate" of $599/£529/649 euros.

Sales slump

Blackberry's own figures indicate it sold about 1.6 million smartphones over the three months to June.

That compares poorly with the 6.8 million handsets it sold in the same quarter in 2013, and 13.2 million over the corresponding period in 2011.

Its fortunes contrast with the wider smartphone market, which has expanded.

Having pioneered the sector, the company now accounts for only 1% of sales in the UK, according to research firm Kantar Worldpanel.

Even so, one company watcher said Blackberry still had appeal to certain organisations, even if they had not purchased its other recent releases in large numbers.

"The key markets it holds are financial services and security-oriented industries," said Martin Bradley from Strategy Analytics.

"Blackberry continues to offer the most secure end-to-end communications architecture in the mobile market, and its devices provide business users with that reassurance."

Voice commands

Other features introduced by the handset and its new operating system - Blackberry 10 OS 10.3 - include:

  • Access to the Amazon Appstore - the phone can run the 240,000 Android apps it contains. But the store lacks some popular products, including photo-sharing network Instagram, and newly released games, such as Fifa 15, both found on Google Play
  • Blackberry Blend - this allows certain tasks on the phone to be controlled by a wi-fi-connected PC or tablet that does not store the data involved, letting users take advantage of bigger screens when available
  • Blackberry Assistant - a facility that recognises voice commands and speaks back in English, French, German, Spanish and Italian
  • A 3,450 mAh battery - this is bigger than most of its rivals, and allows the Passport to promise up to 25 hours of mixed use

The company has also added a new, tougher level of encryption to messages sent via its BBM messaging app to protect them from eavesdropping and manipulation.

"We've already got a lead - we're not going to sit on our laurels," said Mr Beard.

He added that Blackberry also intended to add encryption to voice calls made between its devices in the future but it was "still to be decided" if this function would come to the Passport.

'Deadly serious' new tech bug found

25 September 2014 Last updated at 16:13 By Dave Lee Technology reporter, BBC News

A "deadly serious" bug potentially affecting hundreds of millions of computers, servers and devices has been discovered.

The flaw has been found in a software component known as Bash, which is a part of many Linux systems as well as Apple's Mac operating system.

The bug, dubbed Shellshock, can be used to remotely take control of almost any system using Bash, researchers said.

Some experts said it was more serious than Heartbleed, discovered in April.

"Whereas something like Heartbleed was all about sniffing what was going on, this was about giving you direct access to the system," Prof Alan Woodward, a security researcher from the University of Surrey, told the BBC.

"The door's wide open."

Some 500,000 machines worldwide were thought to have been vulnerable to Heartbleed. But early estimates, which experts said were conservative, suggest that Shellshock could hit at least 500 million machines.

The problem is particularly serious given that many web servers are run using the Apache system, software which includes the Bash component.

Patch immediately

Bash - which stands for Bourne-Again SHell - is a command prompt on many Unix computers. Unix is an operating system on which many others are built, such as Linux and Mac OS.

The US Computer Emergency Readiness Team (US-Cert) issued a warning about the bug, urging system administrators to apply patches.

However, other security researchers warned that the patches were "incomplete" and would not fully secure systems.

Of particular concern to security experts is the simplicity of carrying out attacks that make use of the bug.

Analysis - Mark Ward, technology correspondent

Shellshock rates a 10 on the scale of vulnerabilities. As bugs go, it's about as bad as it gets.

Except that the last big bad bug, Heartbleed, rated an 11, according to one expert.

That should mean Shellshock isn't as bad. Right?

Maybe. It's too early to tell.

With Heartbleed, more work had been done by the folks that found it so it was easier to estimate who was at risk. There were lots of big targets, many of which had large user populations.

With Shellshock, the sheer number of potential victims is higher. And we do know that an exploit has been produced and some folks are scanning sites to see which are vulnerable to attacks based around that code.

So far, what's keeping servers safe is the fact that cyber thieves are lazy and tend to copy what has already worked. Finding exploits is specialised, hard work so they only tend to pile in once that appears. With that code already in circulation, the early news about Shellshock may just be the first tremor of a much bigger quake.

Cybersecurity specialists Rapid7 rated the Bash bug as 10 out of 10 for severity, but "low" on complexity - a relatively easy vulnerability for hackers to capitalise on.

"Using this vulnerability, attackers can potentially take over the operating system, access confidential information, make changes, et cetera," said Tod Beardsley, a Rapid7 engineer.

"Anybody with systems using Bash needs to deploy the patch immediately."

Security firms have suggested that there is evidence Shellshock is being used by hackers.

"The vulnerability has already been used for malicious intentions - infecting vulnerable web servers with malware, and also in hacker attacks," said Kaspersky Labs.

"Our researchers are constantly gathering new samples and indications of infections based on this vulnerability."

For general home users worried about security, Prof Woodward suggested simply keeping an eye on manufacturer websites for updates - particularly for hardware such as broadband routers.

Free questions

The new bug has turned the spotlight, once again, onto the reliance the technology industry has on products built and maintained by small teams often made up of volunteers.

Heartbleed was a bug related to open source cryptographic software OpenSSL. After the bug became public, major tech firms moved to donate large sums of money to the team responsible for maintaining the software.

Similarly, the responsibility for Bash lies with just one person - Chet Ramey, a developer based at Case Western Reserve University in Ohio.

That such key parts of everyday technology are maintained in this way is a cause for concern, said Tony Dyhouse from the UK's Trustworthy Security Initiative.

"To achieve a more stable and secure technology environment in which businesses and individuals can feel truly safe, we have to peel back the layers, start at the bottom and work up," he said.

"This is utterly symptomatic of the historic neglect we have seen for the development of a dependable and trustworthy baseline upon which to develop a software infrastructure for the UK.

"Ultimately, this is a lifecycle problem. It's here because people are making mistakes whilst writing code and making further mistakes when patching the original problems."

Broadband voucher scheme overhauled

23 September 2014 Last updated at 14:20

The government is overhauling its plans for getting ultra-fast broadband to UK businesses after disappointing take-up of its current scheme.

Only £7.5m out of a pot of £100m has so far been spent, with just 3,000 businesses taking up vouchers.

Initially the government had expressed hope of reaching 200,000 small businesses.

With a March 2015 deadline for the money to be spent, the government is keen to galvanise interest.

Changes aimed at making it easier to get the money include a redesigned website and a more streamlined process of applying for a grant.

Other changes include:

  • Qualifying businesses no longer need to fill in an application form but can access the government grant with a call to a pre-approved broadband supplier
  • Businesses that already have a different supplier in mind need only to fill in a form to get their quote approved
  • Suppliers can also apply to BDUK (the group overseeing the process) with a set of eligible connection costs, cutting the need for businesses to apply at all
  • Once a broadband package has been approved, suppliers can market them to eligible businesses with no more need for forms or rubber-stamping

"This is a golden opportunity for businesses to take advantage of better broadband. The grant takes away the costs of installation, which are normally charged up front or added to monthly charges," said Sajid Javid, Secretary of State for Culture, Media and Sport.

'Maximum competition'

The plan to help get ultra-fast broadband to small and medium-sized businesses is part of a wider government strategy to create a network of super-connected cities around the UK.

More than 20 cities, including London, Edinburgh, Cardiff, Belfast, Birmingham, Manchester and Cambridge, were earmarked in 2012 for ultra-fast broadband, defined as minimum speeds of 80Mbps.

Birmingham City Council's plan to spend the money on a 100Mbps (megabits per second) network for the city was challenged in the courts by BT and Virgin Media, with the firms arguing that the state-aided network being proposed would pose unfair competition to their own rollouts in the city.

The European Commission subsequently revised its state aid guidelines and DCMS decided that, to avoid delays to other cities' plans being approved, it would offer the subsidy in the form of vouchers for businesses.

Only companies with fewer than 250 workers can apply for the vouchers.

The government was keen to play up the success of the scheme with a spokesman for the Department for Culture, Media and Sport (DCMS) saying take-up was "increasing on a weekly basis".

But others were not convinced.

"The scheme has not proved as successful as government had hoped," said Malcolm Corbett, head of the Independent Networks Co-operative Association (Inca).

"The problem is that the government can't be seen to aggregate demand as that will fall foul of European state aid rules."

Inca is helping small businesses take advantage of the voucher scheme by encouraging them to group together to get the maximum benefits from the subsidies.

Labour's plans

In Shoreditch, for example, 90 small businesses based in the same building have joined forces and used the vouchers - which are worth about £2,500 each - to provide 100Mbps fibre connections to their premises.

The government's broadband rollout has been described as unambitious by the Federation of Small Businesses (FSB). In a report published this summer it called for a major rethink of the current strategy.

It recommended that the government commit to delivering a minimum of 10Mbps for all homes and businesses by 2018-19, with that rising to 100Mbps by 2030.

As part of its annual conference, Labour will launch its own digital strategy this week.

It will include a plan to bring speeds of 1Gbps (gigabit) to homes and businesses as well as recommending a digital Magna Carta aimed at defining citizens' rights.

Minecraft map of UK adds houses

24 September 2014 Last updated at 00:23 By Mark Ward Technology correspondent, BBC News

A map featuring the UK made entirely of Minecraft blocks has had an upgrade.

Created by Ordnance Survey (OS), the original map re-created 224,000 sq km (86,000 sq miles) of Britain using more than 22 billion blocks.

The updated version uses 83 billion blocks, with each one representing 25m of real-world British soil, road or grass.

The Minecraft UK map is so detailed that people should be able to find their own house on it.

Ordnance Survey said it would put an interactive map on its main webpage so people could generate co-ordinates to lead them to their home on the Minecraft version.

Game play

Minecraft is a hugely popular video game set in worlds built of blocks that can be mined for raw materials that can then be turned into tools, weapons, armour and other items. Many people just play on randomly generated worlds but others build and share custom-created worlds for adventuring.

The original Minecraft map of the UK was created in two weeks by intern Joseph Braybrook in September 2013. The updated version was also created by Mr Braybrook, who recently started working at Ordnance Survey thanks to a graduate recruitment scheme.

Mr Braybrook said the map had been doubled in scale to make it much more detailed. Mapping tools created by OS staff were used to give it a "more expansive appearance that is closer to real life", he said.

The increase in scale means that woods and forests now have computer-generated trees, tributaries to rivers are visible and motorways, local roads and rail links are all accurate.

"I'm looking forward to seeing if people eventually build a working railway system in-game," said Mr Braybrook in a statement.

OS said it planned to make the one-gigabyte map freely available for download for people to play on. The original map has been downloaded more than 100,000 times, said the OS.

However, it added, its relatively coarse resolution limited what could be done with it. By contrast, said Mr Braybrook, the new version should be easier for Minecraft fans to get to grips with.

"I've attempted to re-create Great Britain to be more realistic, while maintaining the gameplay elements people love from the game," he said.

The map is believed to be the biggest Minecraft map made using real-world geographic data.

Paypal deal enables Bitcoin payments

24 September 2014 Last updated at 13:02

Paypal is teaming up with three major Bitcoin payment processors so that certain retailers will be able to receive payments in the virtual currency via the firm's payment hub.

The three processors are BitPay, Coinbase and GoCoin.

The service has gone live and will initially be available to sellers of digital goods based in North America.

However, the payments will not be processed by Paypal itself, the company confirmed.

"We're proceeding gradually, supporting Bitcoin in some ways today and holding off on other ways until we see how things develop," wrote Scott Ellison, senior director of corporate strategy in a blog post on the Paypal website.

"Paypal has always embraced innovation, but always in ways that make payments safer and more reliable for our customers. Our approach to Bitcoin is no different."

Last month Paypal announced that its subsidiary unit Braintree, a payment processor used by firms such as Uber and Airbnb, was also looking at ways to handle Bitcoin payments.

Scott Green, founder of UK Bitcoin price comparison site Bittybot, said the new partnership was significant.

"I think we will look back at this announcement from Paypal as being a major turning point in the mainstream adoption both of Bitcoin and its payment system being taken seriously by businesses," he told the BBC.

Yahoo prodigy opts for university

24 September 2014 Last updated at 14:08 By Leo Kelion Technology desk editor

The British teenager who sold his app for millions of pounds to Yahoo has decided to go to university in the UK rather than work full-time for the tech firm in California.

Nick D'Aloisio said he would, however, still continue to work on its news app.

The 18-year-old had previously managed to combine development of the service with his A-level studies.

Yahoo News Digest has been downloaded more than two million times, according to analytics firm Xyo.

"I am thrilled to be attending Oxford University in England where I will study computer science and philosophy," Mr D'Aloisio said.

"I'm excited to simultaneously complete my college degree while continuing part-time to manage Yahoo News Digest - especially at such an exciting time for summarisation, artificial intelligence and wearables."

Mr D'Aloisio told the BBC earlier this month that the team he managed at Yahoo was developing a version of the news summary app for both Apple Watch and smartwatches running Google's Android Wear.

The Londoner was only 16 years old when he secured a $250,000 (£154,000) investment in his text summary software from Hong Kong billionaire Li Ka-Shing.

A few months later Yahoo acquired the technology and his services, in a deal reported to be worth £20m.

Since taking up the role of project manager for the news app, the teenager has spoken at several high-profile public events including Yahoo's keynote address at the Consumer Electronics Show in January and O2's Campus Party in September.

A spokeswoman for Yahoo said he should now be able to get involved in the BBC's computer coding initiative - a series of television shows and other events designed to encourage people to learn to program - next year, "time permitting".

Samsung ends laptop sales in Europe

24 September 2014 Last updated at 18:08 By Leo Kelion Technology desk editor

Samsung has announced that it is ending sales of its laptop computers in Europe.

The move includes its Chromebook model, which had previously been one of the category's best-sellers.

The South Korean company's decision follows Sony's announcement earlier this year that it was selling its Vaio division and pulling out of PC sales altogether.

However, other firms have recently reported growth in the sector.

Samsung signalled it might consider similar action in other parts of the globe.

"We quickly adapt to market needs and demands," said the company in a statement.

"In Europe, we will be discontinuing sales of laptops including Chromebooks for now.

"This is specific to the region - and is not necessarily reflective of conditions in other markets.

"We will continue to thoroughly evaluate market conditions and will make further adjustments to maintain our competitiveness in emerging PC categories."

Focus on phablets

Market analysis firm IDC has predicted that portable PC sales will grow by 5.6% this year in mature markets, partly offsetting a decline in 2013.

However, Samsung does not feature in its list of the top five PC sellers, and it appears that rivals have accounted for what growth there is.

Lenovo recently reported a 17% rise in revenue from notebook sales in its April-to-June quarter compared to the same period the previous year. It claimed that made it the most popular laptop brand in 15 European, Middle Eastern and African nations.

Apple also posted a 13% year-on-year rise in Mac sales over the same three months, driven in large part by demand for the MacBook Air.

"With Samsung you can clearly see the focus shifting towards the tablet and phablet space, rather than the laptop, and that's clearly from a consumer's perspective where the strength of its brand lies," commented Windsor Holden from tech consultancy Juniper Research.

"With someone like Apple you've got strength across the brand - the 'Macheads' are historically a loyal bunch - and Lenovo is also still doing very well in that market.

"But I think we're seeing a gradual thinning out of the players active in this sector."

Samsung's smartphones have also come under pressure in recent months.

Surveys indicate sales of its phones have been overtaken in India and China by local firms Micromax and Xiaomi.

That resulted in the Samsung Electronics division posting a 20% year-on-year drop in its net profit in June and dozens of executives voluntarily handing back part of their bonuses.

However, in recent weeks its soon-to-be-released Galaxy Note 4 large-screened smartphone and add-on virtual reality headset have both attracted warm reviews.

"What I think you may be seeing from Samsung is a renewed focus on its mobile devices, especially what it is doing in the Android market," said Rhoda Alexander from the IHS consultancy.

"You have a lot of competition in that sector at the moment, and this might be an opportunity for it to concentrate its energies in that direction rather than spreading them all about."

Apple apologises for update bug

25 September 2014 Last updated at 08:49

Apple has apologised after an update to its mobile operating system left some owners of its new iPhones unable to make or receive calls.

Users who had installed iOS 8.0.1 on the iPhone 6 models also complained it had caused problems for the handsets' Touch ID fingerprint facility.

The update had been released less than a week after the phones had gone on sale in order to fix other issues.

Apple said it was working on a new version.

"We have a workaround for iPhone 6 and iPhone 6 Plus users who lost cellular service and Touch ID functionality today after updating to iOS 8.0.1," it said.

"Affected users can reinstall iOS 8 through iTunes.

"We apologise for the great inconvenience experienced by users, and are working around the clock to prepare iOS 8.0.2 with a fix for the issue, and will release it as soon as it is ready in the next few days."

The company has also published a support document that lists the steps affected users can take to revert their devices to the previous version of the operating system.

Pulled update

The iOS 8.0.1 update had been made available online for less than an hour before it was pulled on Wednesday.

MacRumors reported that within that time it had caused connectivity problems for subscribers to networks including EE in the UK, Vodafone in Germany, AT&T and Verizon in the US and Rogers in Canada.

Apple had said the update was intended to fix other bugs including:

  • An issue that could cause unexpected data usage when receiving a text message
  • A bug that had prevented apps designed to work with its HealthKit software from being made available
  • An issue that prevented some apps from accessing photos on the iPhone or iPad's library

While it is common for tech companies to issue bug fixes shortly after the release of a major new version of software, it is not usual for them to have to recall the code.

The mistake comes at a time when Apple has suffered a series of setbacks.

Last week it released a tool to remove the new U2 album from iTunes users' libraries - which it had given away for free - after complaints that its songs had automatically been downloaded to devices without their owners' permission.

On Tuesday, claims were made that some of the new iPhones had bent after being placed in users' pockets - it is as yet unclear whether this is a major problem or not.

And on Wednesday, it emerged that a bug in OS X could leave the company's Mac computers open to attack.

The Shellshock bug also affects computers powered by Linux.

Facebook drones the size of planes?

By Anna Doble Newsbeat online editor

Facebook is considering flying giant drones above us as the social network "figures out how to connect the world".

Chinese stealth drone
Not flying overhead just yet... this is a Chinese stealth drone.

The idea to develop huge unmanned aircraft comes from Facebook's Connectivity Lab, set up by company founder Mark Zuckerberg.

The aim is to make the internet available to two-thirds of the world's population who can't currently get online.

They say expanding internet access would create another 140 million jobs.

And they say it could help lift 160 million people out of poverty, and reduce child mortality.

The lab's engineering director Yael Maguire revealed the drone plan at the 2014 Social Good Summit in New York.

He didn't actually use the word "drone" but said that unmanned "planes roughly the size of a commercial aircraft, like a 747"" would serve as huge connectivity hubs could one day stay up in the air for months, even years, at a time.

Maguire explained: "In order for us to fly these planes we actually have to fly above the weather, above all airspace. That's between 60,000 and 90,000 feet. Routinely, planes don't fly there, and certainly not drones."

He said the aircraft will be roughly the size of 747 commercial aeroplanes, but much lighter, adding that one of the models being worked on by the Connectivity Lab is the length of "about six or seven Priuses, but is the weight of four of the tires of a Prius."

To continuously provide wi-fi coverage the planes will be powered by the sun.

Maguire added that the aircraft could be tested in the US as early as next year, although the strict rules around unmanned aircraft could slow down that process.

Facebook is not the only tech firm exploring the use of drones.

Google is known to be building and testing autonomous aerial vehicles to use for goods deliveries at its secret development centre, Google X, in California.

Google is also looking at balloons to bring internet access to remote parts of the world.

DHL has begun delivering by drone to a remote island in Germany.

And Amazon has created "Octocopters" to deliver parcels to its customers in the US.
