4G – the mobile network that’s used around the world to make calls, send messages and surf the web. Now there are plans for 4G to be replaced by, you guessed it, 5G – a new, faster network that has the potential to transform the internet.
5G is a software defined network – it means that while it won’t replace cables entirely it could replace the need for them by largely operating on the cloud instead. This means it will have a 100x better capacity than 4G – which will dramatically improve internet speeds.
For example, to download a two-hour film on 3G would take about 26 hours, on 4G you’d be waiting 6 minutes, and on 5G you’ll be ready to watch your film in just over three and a half seconds.
But it’s not just internet capacity that will be upgraded. Response times will also be much faster. The 4G network responds to our commands in just under 50 milliseconds.
With 5G it will take around one millisecond – 400 times faster than a blink of the eye.
Smartphone users will enjoy a more streamlined experience but for a world that is increasingly dependant on the internet just to function, a reduction in time delay is critical.
Self-driving cars, for example, require a continuous stream of data. The quicker that information is delivered to autonomous vehicles, the better and safer, they can run.
For many analysts this is just one example of how 5G could become the connective tissue for the internet of things,
an industry that’s set to grow threefold by 2025, linking and controlling not just robots, but also medical devices, industrial equipment and agriculture machinery. 5G will also provide a much more personalized web experience using a technique called network slicing.
It’s a way of creating separate wireless networks on the cloud, allowing users to create their own bespoke network.
For instance, an online gamer needs faster response times and greater data capacity than a user that just wants to check their social media. Being able to personalize the internet will also benefit businesses.
At big events like Mobile World Congress, for example, there is a mass influx of people in one particular area using data-heavy applications. But with 5G, organizers could pay for an increased slice of the network, boosting its internet capacity and thus improving its visitors’ online experience.
When is 5G comming?
So when can we start using 5G? Well, not yet and according to some analysts not until 2020. 5G was created years ago and has been talked up ever since. Yet it’s estimated that even by 2025, the network will still lag behind both 4G and 3G in terms of global mobile connections.
Its mainstream existence faces multiple hurdles. The most significant of these of course is cost.
According to some experts, 5G could cause network operators to tear up their current business models for it to make business sense.
In the U.K. for example, 3G and 4G networks were relatively cheap to set up because they were able to roll out on existing frequencies, on the country’s radio spectrum. For 5G to work properly however, it needs a frequency with much bigger bandwidth which would require brand new infrastructure.
Some analysts believe that the extensive building and running costs will force operators to share the use and management of the mobile network. This has been less of an obstacle for countries like China, who are taking a more coherent approach.
The government, operators and local companies such as Huawei and ZTE are about to launch big 5G trials that would put them at the forefront of equipment production for the new technology.
That may be at the expense of the West, where there is concern regarding Asia’s 5G progress.
A leaked memo from the National Security Council to the White House called for a nationalized 5G network to keep the U.S. ahead of their global competitors. White House officials dismissed the idea, but some experts predict that by 2025 nearly half of all mobile connections in the U.S. will be 5G, a greater percentage than any other country or region.
It’s still likely however that much of the West will have a more gradual approach to 5G, driven by competition but with a patchy style of development.
For example, AT&T, pledged to start rolling out 5G later this year but in just a handful of cities. For key industrial zones however, it’s predicted the technology will be adopted quickly, while for many in rural areas 5G may be a long way off.
But when 5G does establish itself and fulfills its supposed potential, it could even change how we get the internet at home and at work with the wireless network replacing the current system of phone lines and cables.
It may not happen overnight, but 5G is coming.

An Asteroid might destroy everything , Scientists said Apocalypse might Come
Conspiracy theorists have long been claiming that a civilization-threatening asteroid could be on a collision course with the planet. Now, a team of famed scientists is progressing to raise issues concerning these doubtless dangerous space rocks at a global conference in Vienna.
NASA scientists discovered last week that a meteor explosion over the Bering Sea in December 2018 unleashed 10 times the energy as the Hiroshima atom bomb.
The space rock, many meters in size, exploded concerning sixteen miles on top of the earth’s surface. NASA on Friday conjointly revealed satellite photos of the meteor that appeared on December eighteen however went neglected till months later.
This meteor strike at the Bering Sea may be a reminder that, despite efforts to spot and track space rocks that might create a threat to Earth, sizeable meteors will still arrive all of sudden.
These asteroids, known as Near Earth Objects or NEOs will cause the extinction of whole species. it absolutely was an asteroid that hit the planet a lot of years past that has been goddam for the dinosaurs being drained, together with seventy-five percent of all life forms on the world, at that time.
To counter this threat, scientists need to handle the problem – wanting space agencies like NASA and therefore the ESA to accentuate efforts to discover and track NEOs and devise ways that to deflect them. These considerations are set to be raised at the primary meeting of the govt of Asgardia.
Asgardia may be a ‘space nation,’ conjointly called the space Kingdom of Asgardia and “Asgardia the space Nation”, maybe a micronation fashioned by a gaggle of individuals who have launched a satellite into Earth orbit. They consult with themselves as “Asgardians” and that they have given their satellite the name “Asgardia-1.” The space nation conjointly has 20,000 voters and 1,000,000 followers worldwide.
Jay Tate, a number one Asgardian scientist from Knighton, UK and director of the privately-funded Space-guard Centre in Wales, to The categorical, said: “NEOs create a heavy, even cataclysmal, threat to human civilization and action should be taken currently to spot levels of risk and develop the technology to safeguard this and future generations.”
What Astronauts did to Survive First Moon Landing
Beginning of Apollo Space Program
In the shadow of the atomic bomb, science and politics became entwined. And as World War II progressed, countries began to capitalize on the power of technology. This shift in wartime strategy gave way to rapid advancements in weaponry like the development of the world’s first long-range, self-guided ballistic missile.
And unlike those before it, this rocket had the potential to go to space and its creation would ultimately lead to a man on the moon. In the final years of the war, Nazi scientists successfully tested the V-2 rocket, the world’s most sophisticated missile and the first man-made object to cross the Karman line which is commonly represented as the start of space.
When the war ended in 1945, the new world powers were dead set on acquiring the Nazi’s V-2 technology. This man, Wernher von Braun, was known as the brains behind the rocket.
He, along with other Nazi scientists, surrendered to the Americans and were transported to the US under a top secret project known as “Operation Paperclip”. The Germans were put to work, helping American scientists design and build military missiles that would ultimately be used in the beginnings of the space program.
Meanwhile, Soviet scientists were repurposing the remains of Nazi rockets, and they were working much faster than the Americans. By the mid-1950s, the USSR developed an intercontinental ballistic missile equipped with a multi-stage design and multi-engine propulsion system making it capable of reaching orbit.
On October 4th, 1957, the Soviet Union used its new missile to launch the first artificial satellite into space. The satellite known as Sputnik sent a wave of paranoia over the United States. Its Cold War enemy now had a vantage point from space, increasing the fear of a nuclear attack.
The Space Race had officially begun. The US quickly tried to match the Soviet’s success by launching the Vanguard satellite. But the rocket only made it about a meter off the ground before its embarrassing explosion, earning the nickname, “flopnik”. Now in full Sputnik crisis mode, the government shifted its priority to the space race. President Dwight D. Eisenhower accelerated the 1958 launch of Explorer 1 – the first US satellite to reach space and established the National Aeronautics and Space Administration. Within eleven days, NASA launched its first spacecraft and within six months it announced the United States’ first man-in-space program.
Project Mercury had three objectives:
1. orbit a manned spacecraft around Earth
2. Investigate man’s ability to function in space
3. recover both man and spacecraft safely.
In the late 1950s, these were seemingly improbable tasks considering this was all happening around the same time the first computer hard disk was used, the electric printer was invented. Needless to say, technology had a long way to go. On top of that, NASA’s first astronauts had never actually been to space. They did, however, meet all the other necessary qualifications for a job that hadn’t been done before. The candidates were all military pilots, were highly educated and physically fit and they were the right height and weight to squeeze into the one-man Mercury spacecraft. The seven astronauts chosen for Project Mercury were painted as American heroes. And for a country inundated with a fear of nuclear attack, they provided much-needed hope and distraction. After a series of errors, tests and a brave chimp named HAM, in May 1961 astronaut Alan Shepard became the second human in space. The US came up short… again. Less than one month earlier, Russian Astronaut, Yuri Gagarin became the first man to complete an orbital mission. But the trajectory of the Space Race was about to change.
NASA President said, “I believe that this nation should commit itself to achieve the goal before this decade is out of landing a man on the moon and returning him safely to the Earth.” Under pressure to catch up to the Soviet Union at the height of the Cold War, President John F. Kennedy set an ambitious deadline. And from that moment forward, NASA’s human spaceflight efforts were guided by a single goal. NASA’s second man in space program acted as a bridge to the moon.
Project Gemini had four main objectives:
1. test an astronaut’s ability to fly long-duration missions
2. understand how spacecraft could rendezvous and dock in orbit
3. perfect re-entry and landing methods
4. further understand the effects of long space flight on astronauts.
All the while, Project Mercury was achieving major milestones. And on February 20, 1962, astronaut John Glenn became the first American to orbit Earth. By 1965, the first crewed Gemini mission took flight. The missions to follow set a series of firsts not just for the United States but for the world.
A new race was on for the United States. But now it was a race against time. In under five years, NASA needed to land a man on the moon. The Apollo Program would become one of the country’s biggest challenges, costing billions of dollars and risking dozens of lives. But if the decades of war and innovation leading up to this moment proved anything, it was that some of the biggest breakthroughs unfold when pressure is at its highest. And, just like challenges before it, Apollo would redefine the boundaries of possibility, taking humanity on a ride to an entirely new world.
This was how the Apollo program started. Stay tuned to know about the Apollo 11. Turn on the notification to get reminded.
