What Is 5G?
By Sascha Segan
May 1, 2017

AT&T, Verizon Wireless, and other carriers will start to launch 5G networks this year. But what exactly is 5G? Here's what we know so far.

5G is coming this year. Or maybe not. In the race to 5G, or fifth generation wireless, companies are starting to promise the impossible, which will result in a lot of confusion over the next few years.

Because there isn't any official definition of 5G yet, all the players in the wireless world, from chipset makers to carriers, are jockeying to define 5G and establish themselves as 5G leaders.

So head with me down the rabbit hole that is 5G as I try to explain what the heck is going on.

1G, 2G, 3G, 4G, 5G The G in 5G means it's a generation of wireless technology. While most generations have technically been defined by their data transmission speeds, each has also been marked by a break in encoding methods, or "air interfaces," which make it incompatible with the previous generation.

1G was analog cellular. 2G technologies, such as CDMA, GSM, and TDMA, were the first generation of digital cellular technologies. 3G technologies, such as EVDO, HSPA, and UMTS, brought speeds from 200kbps to a few megabits per second. 4G technologies, such as WiMAX and LTE, were the next incompatible leap forward, and they are now scaling up to hundreds of megabits and even gigabit-level speeds.

AT&T's '5G Evolution' Is Not 5G AT&T recently announced its " 5G Evolution" network, which isn't 5G. It's AT&T's brand for gigabit LTE, the latest incremental advance in 4G LTE, which all major US carriers plan to roll out this year.

Gigabit LTE is backwards-compatible with existing phones and runs on existing spectrum. It uses more advanced versions of LTE's existing encoding, along with more antennas and more efficiently consolidated spectrum, to deliver better speeds.

But AT&T's 5G lie also highlights that LTE isn't going away any time soon. 5G, by and large, will operate on very high frequencies, requiring towers or antennas that are relatively close together. It will rely on 4G for broader overall coverage, especially in rural areas.

4G will continue to improve with time, as well. Qualcomm has already announced a 4G modem, the X20, capable of 1.2 gigabit speeds. The real advantages of 5G will come in massive capacity and low latency, beyond the levels 4G technologies can achieve.

AT&T and Verizon Launching Pre-5G AT&T and Verizon have both pledged to launch 5G home internet systems this year. At Mobile World Congress in February, Samsung and Verizon showed off the antennas and routers Verizon's 5G service will use.

The technologies used in 5G for the home will be closely related to millimeter wave fixed wireless ISPs such as Starry in Boston and Monkeybrains in San Francisco, but with bigger players such as Verizon and AT&T in the mix, they'll be much more widely available. AT&T, for instance, has talked to me about potentially using 5G to replace its old DSL offerings, letting the company deliver a "quad play" of DirecTV TV service, 5G home internet, wireless phone, and home phone.

This isn't quite 5G, because the 5G standard won't be set until 2018. But Verizon intends to converge its 5G service with the actual standard, and it's trying to use as many elements of upcoming 5G systems as possible.

5G home internet shows one major advantage over 4G: huge capacity. Carriers can't offer competitively priced 4G home internet because there just isn't enough capacity on 4G cell sites for the 190GB of monthly usage most homes now expect. This could really increase home internet competition in the US, where, according to a 2016 FCC report, 51 percent of Americans only have one option for 25Mbps or higher home internet service.

5G home internet is also much easier for carriers to roll out than house-by-house fiber optic lines. Rather than digging up every street, carriers just have to install fiber optics to a cell site every few blocks, and then give customers wireless modems.

Okay, So What's 'Real' 5G? 5G is a new network system that has much higher speeds and capacity, and much lower latency, than existing cellular systems. The technologies to be used in 5G are still being defined, but there are many details on which everyone agrees.

5G networks will use a type of encoding called OFDM, which is similar to the encoding that LTE uses. The air interface will be designed for much lower latency and greater flexibility than LTE, though.

The new networks will predominantly use very high frequencies that can transmit huge amounts of data, but only a few blocks at a time. The standard will work all the way from low frequencies to high, but it gets the most benefit over 4G at higher frequencies. 5G may also transmit data over the unlicensed frequencies currently used for Wi-Fi, without conflicting with existing Wi-Fi networks. That's similar to a technology T-Mobile is launching this year called LTE-U.

5G networks are much more likely to be networks of small cells, even down to the size of home routers, than to be huge towers radiating great distances. Some of that is because of the nature of the frequencies used, but a lot of that is to expand network capacity.

So 5G networks need to be much smarter than previous systems, as they're juggling many more, smaller cells that can change size and shape. But even with existing macro cells, Qualcomm says 5G will be able to boost capacity by four times over current systems by leveraging wider bandwidths and advanced antenna technologies.

The goal is to have far higher speeds available, and far higher capacity per sector, at far lower latency than 4G. The standards bodies involved are aiming at 20Gbps speeds and 1ms latency, at which point very interesting things begin to happen.

Is 5G for Phones, Cars, or Homes? Driverless cars may need 5G to really kick into action. The first generation of driverless cars will be self-contained, but future generations will interact with other cars and smart roads to improve safety and manage traffic. Basically, everything on the road will be talking.

To do this, you need extremely low latencies. While the cars are all exchanging very small packets of information, they need to do so almost instantly. That's where 5G's sub-1 millisecond latency comes into play, when a packet of data shoots directly between two cars, or bounces from a car to a small cell on a lamppost to another car. (One light-millisecond is about 186 miles, so most of that 1ms latency is still processing time.)

Another aspect of 5G is that it will connect many more devices. Right now, 4G modules are expensive, power-consuming, and demand complicated service plans, so much of the Internet of Things has stuck with either Wi-Fi and other home technologies for consumers, or 2G for businesses. 5G networks will accept small, inexpensive, low-power devices, so they'll connect a lot of smaller objects and different kinds of ambient sensors to the internet.

So what about phones? The biggest change 5G may bring is in virtual and augmented reality. As phones transform into devices meant to be used with VR headsets, the very low latency and consistent speeds of 5G will give you an internet-augmented world, if and when you want it. The small cell aspects of 5G may also help with in-building coverage, as 5G encourages every home router to become a cell site.

For more details, check out Michael Miller's extensive column on 5G technologies.

When Is 5G Happening? AT&T and Verizon's pre-5G is coming this year, but the first official 5G launches will come in 2018, with broad deployment in 2019. The schedule was previously set for 2019-2020, but carriers and equipment manufacturers figured out an accelerated schedule earlier this year.

This is in line with Qualcomm's 5G modem family announcements. The big chipmaker said that its Snapdragon mobile platform will support 5G in 2019. Snapdragon chips are the most popular platform for US smartphones, so you're likely to see 5G, VR-capable smartphones in 2019.

It is a finger in the dyke.

All that needs to be done to make the malware virulent is to change the URL embedded in the program. If it is embedded as text, then it is embarrassingly easy to alter.

Of course, now it will be harder to spread as more systems are now patched.

WannaCry Has a More Lucrative Cousin That Mines Cryptocurrency for Its Masters
The same exploits that enabled WannaCry to spread globally have been in use in another malware attack since April, making far more money in the process.

by Jamie Condliffe and Michael Reilly
May 17, 2017

The same exploits that allowed the WannaCry ransomware attack to spread so quickly have been used to set up an illicit cryptocurrency mining scheme. And it sure was worth it to the hackers.

Late last week, the world was hit by ransomware that locked up computers in hospitals, universities, and private firms, demanding Bitcoin in exchange for files being decrypted. It was able to spread so fast thanks to a Windows flaw weaponized by the U.S. National Security Agency known as EternalBlue, and a back door called DoublePulsar. Sadly, the tools were inadvertently lost and leaked because the NSA considered it wise to stockpile them for future use.

WannaCry was halted by swift work on behalf of dedicated security researchers. But during investigations into the attack, security firm Proofpoint has found that another piece of malware, called Adylkuzz, makes use of the same exploits to spread itself around the word’s insecure Windows devices.

This particular hack has gone unnoticed since April. That’s because unlike WannaCry, which demands attention to get money directly from a user, Adylkuzz simply installs a piece of software and then borrows a PC’s resources. It then sets about mining the little-known cryptocurrency called Monero using your computer. It does so in the background, with users potentially unaware of its presence—though perhaps a little frustrated because their computers are slower than usual.

It makes sense that EternalBlue and DoublePulsar are being used in this way, said Nolen Scaife, a security researcher at the University of Florida. The combination of exploits allows attackers to load just about any type of malware they want onto compromised machines. “It's important to stress that it could be anything—it could be keyloggers, for example,” he told MIT Technology Review. “But what we're seeing is that attackers are using this wherever this makes the most money.”

Interestingly, though, it’s the attack that has until now gone unnoticed that has secured the most loot. WannaCry’s attempt to extort cash in return for unlocking encrypted files has only drummed up $80,000 at the time of writing—probably because Bitcoin, the currency WannaCry’s perpetrators are demanding, is hard to use. Meanwhile one estimate suggests that the Adylkuzz attack could have already raised as much as $1 million.

In some sense, Adylkuzz is less problematic than WannaCry. It’s certainly less overtly destructive. But it does raise a more pressing cause for concern: if it’s been running since April, how many other leaked NSA tools have been used to carry out attacks that have so far gone unnoticed? Stay tuned—there may be more to come.

PC rebooted every time user flushed the toilet
Wiping out the problem needed a brush and a pump, but didn't make a stink
By Simon Sharwood, APAC Editor
23 Jun 2017 SHARE ?

On-Call Welcome yet again to On-Call, The Register's weekly column in which we take readers' tales of odd jobs in odd places, tart them up and present them to you as a bit of light relief on a Friday.

This week, meet “Gary”, who once had a trouble ticket land on his desk stating that “the PC would reset every time the customer flushed their toilet.”

Gary's first thought was that this was “probably static from the customer walking across their carpeted floor, touching the keyboard before sitting down, static discharge doing the rest.”

But then he read more closely and realised the PC was on a farm. Once he visited that farm he found that “the floors were all hard-wood, so that shot that idea to hell.”

The user then suggested Gary observe the PC as they walked to the bathroom. Gary heard the unmistakable gurgling that resulted and watched as the PC did indeed reset itself about two seconds later.

Which was so odd that Gary asked the user to flush again. This time he thought the spotted the “a slight dimming of the lights lasting all of about half a second.” Cue a series of questions about fuses, circuit breakers, power load on the circuit. To which the users answered that they'd had a brand new circuit wired for the computer, but hadn't purchased a UPS for it as they felt it shouldn't have been necessary.

“After some thinking, I asked about where their water came from,” Gary tells us, “and that's when they looked at me kind of funny and replied 'from a well across the drive by the barn'.”

At which point Gary asked when the pump had been replaced, a question the customer could not answer with any more precision that somewhere between one and two decades in the past.

Gary now developed a hypothesis he described as follows: “When the toilet was flushed, the pump had to kick in to fill the tank and that when the motor kicked in, it had such a current draw because the brushes were probably worn out.” That current draw was what dimmed the lights and therefore disrupted power supply just enough to also trip the computer.

The customer was willing to entertain that theory, found a friend willing to replace the pump and found doing so fixed the problem. And just to flush the problem completely, they bought a wee UPS too.

What's the cleverest correct diagnosis you've ever come up with? Write to share your story and you could be next week's anonymised On-Call hero

Sites that block adblockers seem to be suffering
Martin Anderson
Thu 21 Apr 2016
For news publishers the world is constantly ending – not only in over-caffeinated headlines but behind the scenes too. It’s always been so, from Gutenberg to Wapping riots to the internet and the painful conversion from print to digital.

The latest Imminent Apocalypse is the dramatic rise in the use of adblockers – particularly new innovations in adblocking in the coveted mobile space, even at the network level.

Some news publishers have formed a small vanguard with what many business-folks might consider the ‘obvious’ response: to ban or attempt to ban users who consume their content without seeing their ads. In October of last year German publisher Axel Springer banned adblocking users from the popular Bild news website; in December Forbes put in mechanisms to impede content access to adblocking users; in February of this year Wired instituted adblock ban techniques; and in October of 2015 the City AM financial news website likewise ‘scrambled’ content for adblockers.

In all cases the warnings presented to the user instructed them to whitelist the site in their adblocker – or go away. In all cases there are various tricks, including the use of ‘reading’ mode and private browsing, which allow users to get round the blocks; but I thought it might be interesting to see how the sites in question are faring in the wake of their adblock ‘blockades’, according to internet monitoring service Alexa.

Assessing a site’s performance in relation to its efforts to block adblockers, it’s important to consider that these much-criticised measures are often likely prompted by traffic figures that may have been declining in any case, and that all we can conclude with any certainty from the (approximated) information is that the anti-adblock measures failed to reverse the trend. Furthermore one can doubtless see similar declines in sites which have either taken no action against adblocking or which have only experimented with such measures – such as GQ and the Washington Post.

In any case, this is Alexa’s view of those publishers who have not yet abandoned their anti-adblocking measures.

Wired

Wired’s anti-blocking techniques kicked in the first half of February this year, but in this case it seems to be reactive to a longer-term fall in traffic. The slow decline towards Christmas after expo season in September and October would normally be expected, with a rally from mid-January. Instead there is no evidence that Wired’s blocking policy made any difference to what appears to be a headlong traffic slump up to the present time.

Wired’s global rank fell by 174 points to 853rd (hardly shabby) in the period covered, with its bounce rate rising (that’s bad) 3% to 69.60%, daily pageviews down 4.85% to 1.57 and daily time on site down 1% to 2.53 (effectively no change).

Axel Springer / Bild

In the case of Axel Springer’s flagship news vessel, the blockade appears either to have had a disastrous direct effect on a traffic-stream that was fairly healthy, or to have coincided with massively declining website visits for other reasons. The descent begins at the moment the anti-adblock measures are put in place and describes a 45-degree plunge until relative stabilisation in the last two weeks.

Bild maintains its position as the 14th most popular site in Germany, though its global rank fell by 48 to 413 in the year covered. Bild’s bounce rate rose 2% to 38.9%, with daily pageviews little-changed at 3.54, but daily time spent on site per visitor down 6% to 7:07 – the latter figure being an impressive sustain, despite the fall.

Unlike Forbes (below) the adblocking initiative at Bild does not seem to be an exercise in anything but greed; figures were rising steadily from a healthy baseline in the time leading up to the move – declining thereafter.

Forbes

Forbes started out at the same strong baseline a year ago as most of the other graphs, with the blockade apparently initiated to mitigate the effects of a persistent decline since early autumn – usually a turbulent and fruitful time for news. As with Bild, related or not, a drastic and enduring decline (aside from a brief rally in January) seems to be associated with the institution of the blockade in December, with Forbes’ traffic baseline now dramatically lowered.

Forbes’ bounce rate is up 27% to 27.9 (though this is still an extremely good score), with daily pageviews down nearly 9% to 3.16 and daily time on site per visitor reduced 9% to just under three minutes.

City AM

City AM was not starting from the same brash baseline as the other players here, and is the only site of the four whose traffic did not drop at or shortly after the time of the putting in place of anti-adblock measures. However the gentle rise in figures was arrested at the same time the blockade was initiated, and led to a four-month decline from the beginning of 2016, with the site’s baseline struggling to restore position.

City AM’s bounce rate rose 2% to 72.9%, but the domain retained its average daily pageviews of 1.46 and rose its dwell time to two minutes, a rise of 5%.

Those that retreated from blocking adblock In early September of 2015 The Washington Post ran a ‘test’ of anti-adblock measures, of which there appears to be no trace for the adblock-enabled user in this period (though it can sometimes take a number of specific actions in order to trigger a blockade, depending on the level of initial indulgence for adblockers). The Post retains its paywalled structure, which allows 10 free articles per month, apparently meted out via a combination of HTML5 storage, IP-logging, cookies and other factors, before content is restricted.

The Post’s blockade experiment does not seem to register on what appears to be a generally upward trend over the last six months, with the usual caveat of ‘peace at the holidays’ (‘no news’ being bad news):



If anything the Washington Post’s baseline seems to have risen despite its ultimate unwillingness to repel those who are adblocking. The site’s global rank is up 27 to 187, and it retains its place as the 49th most popular site in the U.S., with page views and dwell time both slightly up. Its high bounce rate of 70% likely reflects the sheer number of ‘lightning strikes’ from outward referrers that the site attracts.

In looking round for websites that have instituted blockades, I found many which seem to have repented of their hatred of adblockers – for instance, of all the news sites that The Guardian rounded up for this article about French publications blocking adblock a mere month ago, I can currently find no evidence of any adblock-block at any of the sites mentioned (though L’Equipe retains its paywall block at certain points).

All this is relatively circumstantial fare by way of arguing that deterring adblocking users deters traffic in general, but there are some unusual coincidences in the graphs.

If one was willing to read the trends with a more paranoid eye, it might seem that instituting these deterrents is financially suicidal, since the remnant audience, though fully monetised and ad-enabled, is so much smaller than the one prior to it.
