Hello Friends,

You've already heard about 5G and many of you already know about it. Interesting to see that various other things like vehicles etc. are now termed as 4G, 5G and termed as next generation vehicles inspired by 5G mobile internet connectivity.  But for those who didn't know much about 5G, I'm bringing you this post about 5G.

So, keep reading..

Without loosing our pace or speed, let me start with defining and explaining what 5G is actually.

    WHAT IS 5G   ?     

5G networks are the next generation of mobile internet connectivity, offering faster speeds and more reliable connections on smartphones and other devices than ever before. 5G is the fifth generation of wireless communication standards.

First there was 2G, a set of standards governing wireless telephone calls. The mobile Web did not yet exist. Then, came 3G that made it possible to surf the Internet on a smartphone. After it, 4G arrived delivering speeds that enables video streaming and an entire economy of apps that need sustained reliable connectivity. 

In 2017, the 3rd Generation Partnership Project, the group creates the rules for wireless connectivity, issued the non-stand-alone standard for 5G, which allows 5G to coexist alongside 4G. In June 2018, the 3GPP finalised the standard for stand-alone 5G. In the two years since, infrastructure developers like Ericsson and Nokia have worked with the four major wireless carriers in the U.S. to build out 5G networks and test them with devices equipped with 5G radios that comply with the new standard.

That means your existing smartphone won't catch a 5G signal. The new standard requires a new device. That new device may hit download speeds of 1Gbps, and theorethically hit a peak of 10Gbps. That means then you'll be able to download full length movies in seconds, but it will also open up a world of possibilities you can't even imagine yet. You're already seeing 5G phones capable of gigabit speeds in your real-world testing, but it varies by carrier and by city. Combining cutting-edge network technology and the very latest research, 5G should offer connections that are multitudes faster than current connections, with average download speeds of around 1GBps expected to soon be the norm. Obviously, networks are playing a very significant role in internet and infrastructure. The networks will significantly help power a huge upgrade in Internet if Things  technology, providing the infrastructure needed to carry huge amounts of data, allowing for a smarter and more connected world.
We're connected no matter from which part of the world we are. Thanks to technology and networks 😀. 5G networks are already initiating to appear. They're expected to launch across the world by 2020, working alongside existing 3G and 4G technology to provide speedier connections that stay online no matter where you are.

    HOW DOES 5G WORK   ?     

5G is comprised of 

low-, mid- and high-band spectrum. 5G networks cab operate on two frequencies. These frequencies are sub-6 GHz and millimeter-wave (20-60 GHz). Carriers were already using sub-6 spectrum for existing LTE networks and now they need more of it to build out 5G. Millimeter-wave frequency was previously unused and the advent of 5G has given carriers access to the spectrum that will enable the faster speeds we expect with the new standard. But mmWave has a few drawbacks : Because it's so high frequency, the waves don't travel long distances. In fact, they can't even travel through windows or buildings. That means a device operating on an mmWave-based network like T-Mobile, Verizon and AT&T's 5G networks will need to be extremely close to a 5G node to catch a signal.
That's fine in a dense metropolitan area where you can stick a 5G node every few hundred feet. But in rural areas where there are few buildings or cell towers mmWave won't work. That's why both sub-6 and mmWave are necessary to make 5G widespread and high speed. Sprint is using its existing midband  (2.5 GHz) spectrum to build out its 5G network. At 2.5 GHz, a signal can travel farther but not as fast as with mmWave. As tested by Techradar - They've seen that play out in their testing of Sprint’s network, which doesn't deliver the 1 Gbps speeds that mmWave-based networks from its rivals do, but does allow you to catch a signal more reliably. T-Mobile launched its 5G network using mmWave, but is also now testing it's low-band (600MHz) spectrum to build out it's 5G network.

    SPEED OF 5G     

Now, many of you might be thinking how fast 5G is ? Well, to end up your curiosity, let me tell you that 5G speeds will vary between locations, countries, carriers and devices. If we talk on the whole then average internet speed you can expect should be much greater that what's currently offered on 4G.

According to the Techradar, they have been testing the first 5G networks in the U.S. , UK and Australia and they've found speeds to be a little bit of a mixed bag.

There is a hype from years about the gigabit speeds that will let you download full-length movies in few seconds, 5G is a reality.

However, certain countries have still slow 4G as compared to what we expected from it in speed. It will be noticeable to see how 5G will run in those countries

All four wireless carriers have turned over switch on 5G in the U.S., and you can buy 5G phones that can take advantage of faster speeds on those networks. But, 5G hasn't reached its full potential yet. We can expect better as compared to now when 5G shows the country with faster speeds and lower latency.

Video-streaming is expected to be the killer use case for 5G - at least to start. According to an IHS Market,  78% of people surveyed expect to increase their video-streaming habit once 5G is available.

You can imagine the scenario then, world is already giving enough time and focus on video streaming.

In middle of July, T-Mobile tested the first 5G data session over low-band 600 MHz spectrum, which is the spectrum the Uncarrier is using to round out its 5G network (alongside millimeter-wave)

Techradar tested AT&T's 5G network in Las Vegas where they observed superfast speeds but didn't crack 1 Gbps. They also tested T-Mobile's newly launched 5G network in New York City, where they saw slower download speeds than from AT&T or Verizon but more consistent coverage.

    LAUNCHING OF 5G     

Next, question will strike in your mind is when will 5G launch ? So here's the answer..

U.S. - 

World got surprised by the Verizon launching 5G network at the start of April 2019. This made it the first globally to offer the next-generation network. However, it is available only in limited parts of Chicago and a few other locations. There are just two handsets available to use on the new 5G network currently. In Chicago, US, researchers and reviewers managed to obtain speeds of 300Mbps  (although average speeds tend to be below 100Mbps).
They noticed patchy 5G coverage there and they had to move around the city's various 5G masts yo get this top speed. They didn't tend to get around 1 Gbps quite consistently though. 5G in London, UK is more of a mixed results they found, with speeds in their test ranging from 200 Mbps to 550 Mbps that was still much quicker than 4G, but not the same level as they're seeing in Chicago. T-Mobile will launch its 5G network in the US most probably in coming days. It said previously that it would bring 5G to 30 cities, starting in New York City, Los Angeles, Dollar, and Las Vegas.

AT&T has made available it's 5G network to 19 cities across the states but it still doesn't offer any 5G phones - with your only option for now a 5G Netgear Nitehawk mobile hotspot.

UK - 

EE launched its 5G network as a carrier in UK. It was the first UK carrier to launch its 5G. It rolled out its 5G network with six cities on May 30, 2019. EE also assured to bring 5G to 10 further cities by the end of 2019. It was followed by Vodafone on July 3, 2019, when it launched 5G in seven cities, launching it to a further eight towns and cities on July 17.

Three launched a 5G service in London on August 19, however, it's initially only available for home broadband. However, it will be coming to mobile later this year, as well as to 23 more towns and cities. 02 is the only major UK network not to have any sort of 5G service yet but it plans to launch it out in October.


Australia -

In Australia, Telstra's 5G coverage went live as of May, 2019. They launched first 5G smartphone in Australia - the Samsung Galaxy S10 5G. However, coverage was limited to 10 major citues and regions and, within those regions, was somewhat limited and patchy. This includes Adelaide, Brisbane, Canberra, Gold Coast, Hobart, Launceston, Melbourne, Perth, Sydney and Toowoomba. The launching continues and coverage is increasing steadily. You can check out Telstra's dedicated 5G page to get latest details and updates. Optus hasn't launched or declared anything regarding launch of 5G however, it's official website states that it aims to have 1,200 5G sites built by March 2020, which could indicate a date for public availability.

So, 5G is already hear but you can use it or not will highly depend on your location. Unless, the wireless carrier you subscribe to and the smartphone you own are perfectly aligned, you probably can't use it. AT&T, Verizon, T-Mobile and Sprint have launched their 5G networks but there are catch outs. First, there are only two 5G - compatible smartphones on the market. Samsung Galaxy S10 5G and LG V50 ThinQ 5G. The carriers have launched their services only in some parts of certain cities, with little overlap.

In fact,  according to a recent research, 1 in 3 Americans think they already have 5G. The results showed that 47% of AT&T subscribers who own iPhones think their device is 5G compatible. Some people got confused about AT&T's 5G plans with the 5GE logo that is now appearing on AT&T customers' phones. That logo translates to "5G Evolution", AT&T's expanded service with advanced LTE technologies, such as 4×4 MIMO, which doesn't hit the speeds we expect from 5G ( or even match Verizon's current 4G service, in our testing ).  AT&T still saying  : "We've been talking about 5G Evolution for a while now. We were pretty public about what we were doing and what we were deploying, " Igal Elbaz, senior vice president for wireless technology at AT&T told media at CES earlier this year.

    AVAILABLE 5G PHONES 📱   

Currently, there are three 5G-capable smartphones available in the market : Samsung Galaxy S10 5G , LG V50 ThinQ 5G and the Moto Z3 for Verizon with 5G Moto Mod. Only early adopters should consider buying these handsets at the moment for few reasons. The $1,299 Galaxy S10 5G is available on Verizon and T-Mobile. AT&T is also providing the phone buy only for business customers and developers. The $1,152 V50 ThinQ is currently available only on Sprint but will be available on Verizon shelves later this summer (check website). The Moto Z3 is a tough sell because it requires snapping on a bully accessory. Other 5G devices are coming in 2019, but you can't expect to see a  5G iPhone this year. 

According to reports Apple is waiting to roll out 5G iPhone next year. OnePlus, ZTE and Huawei also have 5G phones in the works that are due out this year (or on sale in other countries). Samsung will also release another 5G phone this year.  A number of 5G phone announcements have been made in 2019 however only a handful are currently available and the choice is further limited by country and carrier.

This next-generation connectivity to a select few Moto Z handsets, plus the Samsung Galaxy S10 5G is also available.
For those in the UK, you can currently go for six 5G phones. They are - Samsung Galaxy S10 5G, Oppo Reno 5G, OnePlus 7 Pro 5G, Xiaomi Mi Mix 3 5G, Huawei Mate 20 X 5G and LG V50 ThinQ 5G. The Samsung Galaxy Note 10 Plus 5G is also available for pre-order at the time of writing. In Australia, only three 5G smartphones are available and only two of these are available outright. The Oppo Reno 5G and the LG V50 ThinQ 5G can be purchased for AU$ 1,499 and AU$ 1,729 while you'll need to look for a plan with Telstra in order to score the Samsung Galaxy S10 5G. A latest launch is Vivo Nex 3, Vivo Nex 3 5G With 64-Megapixel Camera, Waterfall Display.  Xiaomi Mi 9 Pro 5G, Mi Mix 5G, MIUI 11, Mi TV Range is Launching on September 24.

More About 5G :

People can identify the G's, that is 2G, 3G, 4G and now 5G with smartphones because that way they've been able to see an indicator of connectivity they're getting. 5G's faster speed will mean much more than just higher-quality streaming and lightning quick downloads.

Robert J. Topol, intel's general manager for 5G business and technology have said during an interview at last year's Mobile World Congress that "5G will be the post-smartphone era. Phones are the first place to launch because they're such an anchor in our lives from a connectivity standpoint."
That's about to change. Lower latency will make augmented reality and virtual reality more useful - and eliminate nausea because there won't be any lag. AR glasses and VR headsets haven't yet cracked the mainstream but tech companies are betting that these devices will eventually replace our smartphones with 5G that could actually happen.

5G could transform schools by enabling virtual- and augmented-reality experiences that will bring concepts out of textbooks and into real life for kids in classrooms. Faster connectivity and no latency could also revolutionize hospitals, enabling holograph-assisted surgeries. On the roads,  5G could make self-driving cars safer, because communication between vehicles and infrastructure will become instantaneous. This isn't going to happen overnight but expect major shifts. Thanks to 5G in the next five years.

Future Of 4G ?

Unlike past generations of connectivity, 4G and 5G will share coexistence. When your device drops a 5G signal, it will fall back on LTE. The hand-off should be imperceptible. This will be especially useful in areas of the country where 5G networks will take longer to get off the ground. And carriers are making improvements to their network to prepare for a nationwide 5G launch will make 4G better too.  When researchers tested AT&T's 5G network in Las Vegas, they hit 900 Mbps over 5G. LTE can't compare but they clocked over 290 Mbps on an iPhone running on AT&T's 5G (advanced LTE) network. That's exponentially better than AT&T's existing LTE network, which averaged download speeds of 32.91 Mbps earlier this year.

    DANGERS OF 5G     

People are concerned about it though there is no evidence to suggest that 5G is dangerous to your health. It is believed from years that radio waves can cause brain cancer in humans and this belief has spread in last few years more, seemingly affirmed by a 2000 scientific study of high-frequency waved and their effect on human cell tissue. A recent New York Times report examined that study and found it to be based on a misunderstanding of the human body - specifically, the skin's ability to shield the brain from radio waves. Some researchers at Live Science have also looked into this matter of dangers - or lack thereof - that 5G can pose and found that while there is no reason to be alarmed about the launch, more studies will and should be conducted as 5G becomes more widespread to determine it's impact. Thus, I recommend you to keep an eye of researchers if any done showing any such results and published. 

As you know, 5G is here and at present it is a little disappointing. But it should change as more cities come online and more 5G devices become available. 2019 is the year when 5G starts to appear but 2020 will be when next generation networks will have a meaningful and greater impact on people. Next year, you can expect the first 5G iPhone and nationwide coverage of 5G too. And, then 5G will go to it's full potential.
