Can you survive on 4G alone?


Although this article is related to the UK's recent 4G launch nationwide, it gives a good capsule summary of the use of 4G and its limitations.

As competition increases, the cost of 4G services will come down and operators will offer shared data plans that will allow customers to combine all their smartphone and tablet mobile broadband bills on a single contract.
The arrival of 4G services in the UK may even prompt some people to consider abandoning their fixed-line services altogether. The necessity of a fast and reliable broadband internet connection is the only reason many people pay for a landline, and 4G speeds promise to match and even exceed most existing fixed-line services.
Moving house with 4G
When the time came for me to move house, and I was told that it would take several weeks for a BT engineer to install my new broadband connection, I decided to put this idea to the test, and see if I could survive for a month on 4G alone.
EE agreed to lend me an Alcatel One Touch mobile WiFi (MiFi) dongle with the ability to connect up to 10 devices, which I was able to set up in instantly when I arrived in my new flat. I was supplied with an 8GB data allowance, which costs £41 per month on a 12-month contract.
My partner and I immediately connected several devices to the MiFi and began browsing the web simultaneously. The browsing experience was extremely fast, and even when we invited visitors to connect the 4G, the level of service did not degrade.
Speed tests using Ookla revealed that the average download speed was around 20 Mbps and upload speed was around 11 Mbps. While this is slower than EE’s promised average download speed of 24- 30 Mbps, it is still faster than my previous BT connection, which provided around 9 Mbps download speeds.

As well as browsing the web and social media, we were able to watch videos on YouTube and stream music from Spotify without any interruptions for “buffering”. However, the real challenge came when we decided to stream HD video from LoveFilm Instant.
After some initial problems, where the screen seemed to stutter and we were forced to pause and refresh the page, the programme played fairly smoothly. There were a few moments where the picture became pixelated, but no more frequently than with a BT connection.
Data caps
What was really noticeable, though, was how quickly we chewed through our 8GB data allowance. A 2-hour standard-definition movie is about 1.5 GB, and a 2-hour high-definition movie is about 4 GB, so our 8 GB data allowance was gone in a flash.
If the data allowance is reached, the user is asked to buy a top-up data bundle, costing £3 for 50MB, £15 for 2GB, or £20 for 4GB. It is clear that, for heavy internet users, such as film buffs and online gamers, this could become very expensive very quickly.
EE does offer a 20GB package for £61 per month with a 12-month contract, or £51 per month with a 24-month contract. This would be a sufficient for most casual users, but film buffs and online gamers would still struggle to stay within this limit.
By contrast, O2’s largest 12-month 4G data package is 5GB for £36 per month, with top-up data bundles of 500MB for £6 and 1GB for £10. This means it would cost £156 per month for 20GB of data from O2.
Vodafone’s service is unlimited for the first three months. However, its largest 12-month 4G data package after that is 8GB for £36 per month, with top-up data bundles of 250MB for £6. This means it would cost £332 per month for 20GB of data from Vodafone.

To put those numbers in perspective, BT's 40GB Infinity package costs £30.45 per month, including line rental, while Virgin Media offers unlimited data usage starting from £22.50 per month.
“The capped data could be an issue at this stage for anyone trying to replace fixed-line broadband services with 4G,” said Matthew Howett, analyst at Ovum.
“Generally consumers don’t have a great understanding of how much data they use. Most of us don’t use as much data as we think on our phone, but the sort of things we do with fixed broadband - like streaming of catch-up TV and so on - uses quite a lot of data.”
Speed and contention
Howett said that the browsing experience using 4G is highly influenced by the number of other people using it at the same time. At the moment, EE’s network is fairly empty, so the download speeds and upload speeds are very fast, but this could change as the network becomes more congested.
Although fixed-line networks can also slow down when they become congested, "contention" is more of an issue for mobile networks, because the pipes they use to deliver the data are not as fat as those used by fixed-line.
EE recently doubled the amount of spectrum that it has allocated to 4G, and in doing so it not only doubled the speed of its 4G service, but also reduced the issue of contention. However, if every EE customer started using a MiFi dongle with 6 devices attached to it, the impact on the network would be noticeable.
Meanwhile, O2, Vodafone and Three are all limited by the amount of spectrum they won in the 4G auction earlier this year. They do not have as much spectrum set aside for 4G as EE at this stage, so their services are likely to be considerably slower, and contention could be more of an issue from day one.
Drawbacks
While my experience proved that it is possible to live on 4G alone - albeit expensively - it is easy to see how users could run into difficulties fairly quickly. There is no way to connect to the MiFi device using a cable, so anything that is not WiFi-enabled cannot be used.
There is also a limit on the number of devices that can connect to the MiFi at one time, so large families or households with multiple devices may suffer. This could become more of a problem as the houses themselves become connected, with lights, heating and appliances all needing an internet connection.
Due to restrictions on the amount of spectrum used for 4G, the difference between peak and off-peak broadband speeds could be more pronounced, as the operators will have to employ traffic management techniques.
Moreover, some mobile operators might block access to certain applications, such as Skype, or make users pay a premium to access those services, so it is important to check whether there are any applications that cannot be used over the network.
Finally, it is worth noting that not having a landline means having to pay premium rates for 0800 and 0845 numbers, which can become very expensive if you are moving house. Ofcom has said it wants to eradicate 0845 and 0800 call charges from mobile phones. However, the changes will not be implemented until the start of 2015 at the earliest.
Rural broadband opportunity
In spite of these drawbacks, mobile operators have a fantastic opportunity to replace broadband in areas where fixed-line broadband coverage is very poor.
EE claims that its 4G service will cover 98 per cent of the population by the end of 2014, while O2 has an obligation to provide 98 per cent of the population with a 2Mbps service by 2017, as part of the terms of the 4G auction.
EE has so far focused on towns and cities, and other operators are expected to do the same when they roll out their 4G services, in order to attract as many subscribers as possible. However, EE has been trialling its 4G broadband service in rural parts of Cumbria, and Three has also expressed a desire to serve rural areas of the UK.
When 4G does roll out across the countryside, it is likely to offer a better service than fixed-line in many areas, where people still struggle to get 2Mbps. In these cases 4G could be a good option for consumers, as long as mobile operators bring the prices down.
"Our 4G footprint will pretty closely match our 2G footprint and, as such, there will be data services brought to parts of rural Britain where people have never had mobile data services before," said Paul Ceely, head of network strategy at EE.
"I don’t think we would advocate shifting entire regions of fixed onto mobile. If you’ve got access to superfast broadband in your area, then we’d probably advocate that you continue to use that. But in those areas where it’s hard to get fixed, people should give it due consideration."
Ceely added 4G could also be a good option for individuals who do not want a long-term contract commitment, like university students or other people who are only living in a certain place for a short amount of time.
"We have a number of examples of businesses benefitting too – a construction company that used to have to wait an average of 30 days for broadband installation when they arrived at a site, but now they can set up the moment they arrive because they take mobile broadband from EE," he added.
4G or not 4G?
The question is not so much whether it is possible to live on 4G, but whether it is really a practical solution. This experiment would currently be impossible for 40 per cent of the population, and the 60 per cent that does have access to 4G mobile broadband needs to think carefully about the implications of abandoning fixed line.
Connectivity is an increasingly important part of our lives, and we are less and less willing to accept limitations on our online activity. As the internet has evolved, fixed-line operators have adapted their networks to meet consumer needs, but mobile networks were never built to carry vast quantities of data, and this continues to be a problem for operators.
The prohibitively high cost of large 4G data packages is part of the fallout from this, and it is hard to see how mobile operators will bring down prices without imposing more limitations on their networks - particularly while the national rollout is underway.
Once 4G is established, however, and operators are forced to differentiate on more than just coverage, then 4G may become a truly viable replacement for fixed-line services.

Throw away your trainers


Sportswear fans of the world unite, and throw away your trainers!
Not only is this fashionable footwear hideous, it may even be damaging to run in, according to Northumbria University sports scientist Dr Mick Wilkinson
A sports scientist has claimed that flexible, flat shoes are better for you than more expensive, cushioned trainers 

By Harry Mount

The biggest disaster in the history of footwear was the development of ethylene-vinyl acetate, or EVA. EVA is the squidgy cushioning – formed by millions of microscopic air bubbles – slapped on to running shoes in the Seventies. Suddenly, we went from elegant plimsolls and Dunlop Green Flash (as worn by Fred Perry in the Thirties) to the most unflattering shoes ever invented. The gaudy dinghies at the end of our legs got even bigger in 1979, with the insertion of the air bubble into the heel of the “Nike Air” model.
The modern trainer – outsized, brightly coloured, smelly – is the polar opposite of the beautiful shoe. Now, the one supposed merit of this form of athletic footwear – that it’s good for the health of the running human body – has been officially attacked.
Dr Mick Wilkinson, a Northumbria University sports scientist, told the British Science Festival in Newcastle this week that flexible, flat shoes are better for you than more expensive, cushioned trainers. Feet are meant to land on their front part when you’re running; trainers with cushioned heels force you to land on the heel, causing a sharper shock and adding extra strain to joints such as the knee. Already, in America, barefoot running has become popular, as people realise that humans are designed to run long distances without having to wrap their feet in the scientific equivalent of cotton wool.
It’s too much to hope for that children – and their parents – will immediately ditch their stinking, lurid trainers. The trainer is too embedded in modern fashion for that. But still, here’s hoping that there’ll be a gradual return to the slimmer, prettier gym shoe, which dominated sports from the late 19th century until the dreaded introduction of EVA.
The gym shoe, or plimsoll, was the result of another invention: the adaptation of vulcanised rubber to footwear. Under vulcanisation, natural rubber loses its stickiness, as well as its brittleness when cold and its softness when warm. In the 1870s, John Dunlop’s Liverpool Rubber Company patented a way of sticking rubber to canvas, and the gym shoe was born.
It assumed different incarnations on either side of the Atlantic. In America, it became known in the 1880s as the sneaker – thought to derive from the silence of the rubber sole. Keds was one of the first companies, in 1917, to sell the sneaker on a mass scale. In the same year, Converse launched its own All Stars basketball shoe.
Over here, as early as the 1890s we had the J W Foster – later to become Reebok – running shoe, the first to include spikes. In Germany, in 1925, Adi Dassler – father of the Adidas brand – dreamt up a whole range of running shoes, with customised varieties of spikes.
For all their early popularity, running shoes then were used for exactly that – running. The idea that you might wear them with a suit – as Paul McCartney and bolshy teenagers do at formal occasions – would have been an outrageous demolition of the Chinese wall between formal clothes and sportswear.
The Americans were the first to break down this wall. In the Twenties, American boys started to wear Converse off the baseball field in imitation of their heroes. By the Fifties, sneakers were a mass-market item for American teenagers, not least thanks to the almost complete absence of school uniform – in 1957, 600 million pairs a year were sold.
We lagged behind – not just in terms of consumption, but also acceptability at formal gatherings. As late as the Eighties, Peter Cook was refused entry to his favourite casino because of his shoes. When offered alternative footwear, he said, “What? Play without my lucky trainers? You must be joking.”
The first classic “trainer” – the 1968 Gola training shoe, thought to have provided the origin of the word – would not have been allowed in many restaurants, let alone casinos. Then, in the Seventies, barriers to sportswear in non-sporting scenarios collapsed. Look at a photograph of the typical British family on the beach in the Sixties, and compare it to the Eighties. We began to look like a nation of retired sportsmen, who had given up exercise and turned our attention to chips, but held on to our old kit.
By this stage, the conditions were perfect for the creation of hideous sportswear. In 1977, Jim Fixx, the inventor of jogging, wrote his bestseller, The Complete Book of Running. Dress codes collapsed: Woody Allen wore trainers to the ballet; Dustin Hoffman sported a pair as the Watergate journalist, Carl Bernstein, in the 1976 film, All the President’s Men. And podiatrists were recruited by trainer manufacturers to start bulking out shoes with all that supposedly health-protecting sponge.
Britain’s feet gave in without a battle, swayed by the trainer’s popularity with rappers, and lucrative endorsements by sports stars. In the mid-Eighties, I remember buying a pair in Pembrokeshire, and being told by the salesman that they were “excellent for school – and disco”. The idea that I might use them for neither, but to play football in, hadn’t occurred to him.
Over the past 30 years, that attitude has come to dominate the British wardrobe. But maybe, just maybe, these latest revelations will reverse the trend. Sportswear fans of the world, unite, and throw away your trainers! Your knees will thank you, and a nation’s dress sense will recover some of its dignity.

Can you survive on 4G alone?


EE is no longer the only mobile operator offering 4G data in Britain. With the launch of 4G services from Vodafone and O2 today, and an additional service from Three expected in December, the stage is set for the real 4G battle in the UK to begin.
4G is expected to spread rapidly. Market analyst Analysys Mason predicts that the UK will be the third largest 4G market in Europe by the end of 2014, with nearly 8 million connections.
As competition increases, the cost of 4G services will come down and operators will offer shared data plans that will allow customers to combine all their smartphone and tablet mobile broadband bills on a single contract.
The arrival of 4G services in the UK may even prompt some people to consider abandoning their fixed-line services altogether. The necessity of a fast and reliable broadband internet connection is the only reason many people pay for a landline, and 4G speeds promise to match and even exceed most existing fixed-line services.

Driven: Volkswagen Golf GTI DSG - Contrived?

Driven: Volkswagen Golf GTI DSG - Telegraph
From the point of this reviewer, the GTi 7 looks to be a great car, but not a great improvement over the previous iteration. Coupled with the prevalent gearbox issues, this may not be the marque I'd have right now. Time to switch to something else?
