ZTE is looking into the 5G future with the ZTE Gigabit Phone

The 5G era is not too far away. However, most smartphone manufacturers are in no hurry of exploring it, trying to focus on solid present-day devices, instead of dreaming about the future. But other brands, such as ZTE, are looking to push towards new and exciting technologies, as they try to play with the big boys.

This is probably why ZTE just announced that it will have a “forward-looking” device on display at MWC – the ZTE Gigabit Phone. According to the Chinese company, the handset will be setting new standards for download speeds, at 1 Gbps. This should allow …

How to tell if an iPhone is Locked or Unlocked to a specific network

When buying a new (or second-hand) iPhone you should always check that it is unlocked. An unlocked iPhone can be used on any phone network, and is worth more money than a locked iPhone. This feature looks at how to check if an iPhone is locked or not.

How can I tell if an iPhone is unlocked? Does it say in the Settings somewhere?

It’s important to know how to check an iPhone’s network status. Apple iPhones come in two flavours: locked and unlocked. An unlocked phone can be used on any phone network, while a locked phone can only be used on the network the phone is locked to.

An iPhone that can be used on any network is described as “unlocked”. The iPhones you pay full-price for (typically from the Apple Store) are unlocked by default. But an iPhone bought from a network, usually as part of an on-going network plan, is locked. This is normally for a set period, 18 or 24 months, and the cost of your contract covers part of the cost of the iPhone device.

Which iPhones are locked and unlocked?
It’s not possible to tell, just by looking at the handset, whether an iPhone is locked or unlocked. Apple does not allow other phone companies to brand iPhone devices. You don’t get Three- or EE-branded iPhones, for example.

To confuse matters even further, some phones are locked when sold, but are unlocked at a later date when the original owner has paid for the initial contract.

check-if-iphone-is-unlocked

The simplest method of checking if an iPhone is locked or unlocked, and the one we’ll use first, involves a quick look in the Settings app.

You’ll need to be able to power up the iPhone and access the cellular settings (you may need to enter the four-digit passcode). Follow these steps to check in iOS if an iPhone is unlocked:

  1. Open Settings.
  2. Tap Mobile (if the device is set to American English it will say “Cellular” instead).
  3. Check for an option named Mobile Data Network (or Cellular Data Network)

If you see an option for Mobile Data Network then your iPhone is most likely unlocked. This option should not appear on locked iPhones.

This method is reportedly not 100 per cent effective, however. If you need to know for sure – if you’re buying a second-hand iPhone, for example, and want to know if you’re paying a fair price – you should use a SIM card to check that it is unlocked. We’ll walk through that method next.

How to check if an iPhone is unlocked using a SIM card

It’s best to have two SIM cards, from different networks. One is usually the SIM card you own, and then other will be the one in the iPhone. Follow these steps to check that the iPhone is unlocked:

1. Make a phone call using the current SIM card. Make sure it connects.
2. Power off the iPhone. Hold down the Sleep/Wake button and use the Slide to Power Off option to switch off the iPhone.
3. Use the SIM-card ejector tool (or a paper clip) to eject the SIM card from the iPhone.
4. Insert your new SIM card.
5. Press the Sleep/Wake button to wake up the iPhone.
6. Make a phone call. Check that the iPhone can connect a call using the new SIM card.

If the phone call does not connect with the new SIM card, then the iPhone is locked.

5G Standard Finally Defined as 20Gbps Speed at 2018

The International Telecommunication Union (ITU) has agreed on a preliminary definition for 5G standard. Recently a conference was held from June 10th to 18th where the speed more than 20Gbps more than was attributed to 5G.

5g-mobile-network-wi-fi

So if a mobile network should provide a data speed at up to 20Gbps, it would be termed as 5G. The current 4G LTE mobile networks operate up to the speeds of 1Gbps which is about 20 times slower than the 4G networks.

Now let’s talk about the real speeds that users will get. 5G is expected to deliver an actual speed varying from 100 to 1000 Mbps that is again a 10 to 100 times increase over the usual 4G speeds. If these standards are fulfilled as promised, the current internet speeds would seem like the vintage 56k modem.

Just like the term IMT2000, which was used for 3G services, the 5G services are likely to be named IMT 2020. The currently popular 4G services were named as 4G advanced. According to the ITU, “WP 5D (Working Party) will define in detail the performance requirements, evaluation criteria and methodology for the assessment of new IMT radio interface.”

With 5G, the next-gen 4K and 8K online video playback will be more viable and this could also be used to cater millions of IoT devices inside a large are together.

The ITU expects the commercial 5G to be used from the year 2020 after its international spectrum distribution in 2019 and it is expected to be showcased at the 2018 Pyeongchang Winter Olympic Games.

5G Network with 1TB Download Speed Coming

How would you like a download speed of 1TB per sec on your smartphone? Sounds unbelievable, doesnt it! Researchers at University of Surrey have managed to achieve a breakneck speed of 1TB under test conditions, while testing Fifth Generation Mobile Telephone or 5G network in University of Surrey labs.

5G-network-1-TB

This was disclosed by Professor Rahim Tafazolli at the #V3 Enterprise Mobility Summit. Professor Rahim Tafazolli is the director of the 5G Innovation Centre (5GIC) at University of Surrey and has been overseeing the 5G tests.

Prof.Rahim told V3 that, “it was the first time in the world that such speeds had been achieved, far faster than any other tests such as Samsung’s 7.5Gbps results.”

Explaining the working of 5GIC, the professor said that it had been researching on the latest technologies which can support 5G services. The technological innovations meant that the research team had been able to achieve the 1TBps results. “We have developed 10 more breakthrough technologies and one of them means we can exceed 1TBps wirelessly. This is the same capacity as fibre optics but we are doing it wirelessly,” he told V3.

Prof. Rahim said that the research team carried out the tests in lab conditions over a distance of 100 meters using transmitters and receivers build by them. He added that they will conduct test outside the university premises in late 2016 or early 2017 and hoped that they could hold a public demonstration in early 2018.

Hoping to stay ahead of other research teams from South Korea, Russia and Japan, the professor stated that, “We want to be the first in the world to show such high speeds.”

Ofcom believes that speeds of 50GB/s is possible on 5G networks when they are deployed commercially but 1TB seems a bit far fetched in the tough physical conditions outside the university test labs. But the professor does not think so, he says that this speed seems achievable provided they can come up with higher latency and reliability.

“An important aspect of 5G is how it will support applications in the future. We don’t know what applications will be in use by 2020, or 2030 or 2040 for that matter, but we know they will be highly sensitive to latency,” he said. “We need to bring end-to-end latency down to below one millisecond so that it can enable new technologies and applications that would just not be possible with 4G,” he added.

Though 5G is only on lab stage right now, commercial deployment of 5G networks will hopefully be started by the year 2020.

Japan is planning to bring 5G network by 2020

The Japanese government continues its support for the development of network technology, pushing together with local companies in trying to make 5G (5th generation) mobile bandwith available by the year 2020 – which is, incidentally, the year the Tokyo Summer Olympic Games roll in – way before other countries do.

Long Term Evolution – or more popularly, LTE – has been more or less the standard in Japanese mobile networks, growing in popularity and usage since it was launched in 2010. LTE is technically not 4G, as misrepresented in most marketing ploys – it is 3.9G, with a standard bandwidth of around 70 to 80 Megabits per second. With 5G technology, Japan is looking at speeds of 10 Gigabits per second. For comparison, if you think your LTE connection is fast enough, imagine speeds 100 faster than your current LTE. This kind of connection is of course primed for higher densities of content, like 4K videos. We might not be seeing a lot of 4K-resolution videos at the moment – and there are not a lot of screens, whether TV ormobile gadgets, that can handle 4K video – but Japan is looking at 4K and even 8K video to be developed in the near future. For those kinds of high density content, 5G connections will be almost essential.

With this in mind, Japan’s Ministry of Communications plans to give the private sector impetus for developing 5G network technology faster than other countries. The ministry is planning to take this proposal to Japan’s three big mobile carriers this year – that is, NTT Docomo, KDDI and SoftBank – as well as smaller communications companies and manufacturers of cellular phone technology and network hardware, the likes of Panasonic, Sharp and Fujitsu. It is understood that the ministry will be looking for government support for funding the development of 5G technology. The Japanese government is even hoping to pull in the considerable abilities of Japanese universities to make sure Japan is way ahead of rivals in Europe and South Korea in this endeavor.

NTT Docomo looking toward 5G mobile network infrastructure by 2020

NTT Docomo, Japan’s largest mobile network by virtue of sales, has released a statement of its ambitions for an ultra-high speed 5G network in place by the year 2020. Presenting the available details of this plan to the technology media at this year’s Combined Exhibition of Advanced Technologies (CEATEC) Japan, Docomo hopes to join other major technology outfits in coming up with their own 5G network by the end of the decade.

According to Docomo, 3G frequencies – that is, the standard network infrastructure including HSDPA, HSUPA, and HSDPA+ – are getting a bit crowded because of the ubiquity of smartphones in the current market. As with the current leading edge 4G LTE-Advanced, Docomo will aim to use higher unused frequencies with its 5G plan. This goal will utilize additional smaller cells along with the current ones to boost the network signal. The small cells would cover smaller areas, with the company planning to use a lot of these in regional batches. The 5G concept is not a finished product yet, as the concept and indeed the global standard, is still being developed. But the Japanese mobile communications leader is aiming to have the 5G technology and infrastructure come together by 2020.

NTT Docomo is not alone in pursuing 5G speeds. In May this year, South Korean mobile giants Samsung revealed that it had hit 1Gbps during testing of its own 5G technology. As Samsung noted at the time, using high-frequency bandwidths – for 5G, it may fall in the 6GHz range – will pose issues in transmission, as the range of these frequencies will be smaller. This is the current problem for most 5G developers, but it should be ironed out eventually. Chinese technology outfit Huawei has also claims to be on the development of 5G network technologies, which it plans to have ready for 2020. Everybody seems to peg 5G by the end of the decade, but for consumers and smartphone users, it just means that 2020 could be a breakthrough year for handheld download speeds.

5G Networks By 2020? Samsung Looks To The Future

Samsung is looking some seven years into the future and claims to have built and tested a 5G wireless network capable of delivering one-gigabit-per-second speeds. Though many parts of the world are still scurrying to build out their 4G networks, Samsung says they´ve developed the necessary technology to operate in the millimeter-wave Ka bands and deliver such ultra-fast speeds.

The Korean company claims their “mmWave Mobile Technology” is a proven solution, and by pitching in with others in mobile research, they hope to have this network “commercialized” by 2020.

“The millimeter-wave band is the most effective solution to recent surges in wireless Internet usage,” said Chang Yeong Kim, executive vice president of Samsung and head of their digital media research in a statement.

“Samsung´s recent success in developing the adaptive array transceiver technology has brought us one step closer to the commercialization of 5G mobile communications in the millimeter-wave bands.”

Delivering faster wireless broadband speeds requires a larger data pipe. Current “4G” networks operate on the lower end of the frequency spectrum. The mmWave network is said to broadcast signals at higher frequencies and can theoretically deliver speeds up to several hundred times faster than 4G. Though widening the spread of frequencies used seems like a viable way to offer a faster and more full-featured network, previous research has shown that these high-frequency, millimeter-wave bands might not be well suited for transmitting data over long distances.

Enter Samsung´s adaptive array transceiver, a cluster of 64 antennas which has been shown to successfully transmit data in the 28 GHz range (4G networks often operate in the 800 MHz range) at around 1.056 Gbps and across a distance of about 1.2 miles. Samsung claims this array of 64 antennas can mitigate any radio reception lost to operating in these millimeter-waves lengths.

Though Samsung claims that their network will be able to deliver data at one gigabit per second, this isn´t the first time we´ve heard about wireless networks operating at these speeds. LTE-Advanced is the next great wireless advance to be commercialized, and it can transmit data at a theoretical 1Gbps. More realistically, however, it will deliver speeds of 15 megabits per second, or about 25 percent faster than the average 12 megabits per second delivered by today´s 4G networks. In an interview with CNN following this year´s Mobile World Congress in Barcelona, Tod Sizer, the head of wireless research at Alcatel-Lucent´s Bell labs said 5G has more to offer than speedy data.

“5G won’t be about more speed, necessarily. It may be faster, but it will be more about meeting the expectation of service quality,” said Sizer.

Each new iteration of wireless networking has brought about a new feature in addition to fast speeds. For instance, 2G delivered better voice quality, 3G delivered data and 4G has enabled faster video streaming.

5G is expected to be ubiquitous enough to handle millions of connections and deliver wireless connectivity to millions of other connected devices. Samsung specifically mentions using their 5G network to deliver 3D movies and games as well as ultra high-definition content and even remote medical services. The Galaxy maker also said they plan to jump into this increasingly competitive 5G market and further the research with their adaptive array transceiver. For now it seems Samsung sees 2020 as a very real goal for rolling out 5G networks to wireless providers all over the world.
