What you need to know about the upcoming 5G era

In 2019, a major technological change is finally about to begin. This is a ten-year upgrade of our wireless system and will begin to reach mobile phone users within a few months.

But it’s not just about making smartphones faster. The transition to the new fifth-generation cellular network (referred to as 5G) will also affect many other types of equipment, including industrial robots, security cameras, drones, and cars sending traffic data to each other. By providing mobile Internet speeds that allow people to download the entire movie in seconds and have the potential to make a huge difference to video games, sports, and shopping, this new era is relatively new to current wireless technology-4G- One leap.

US and Chinese officials see 5G networks as a competitive advantage. Faster networks can help spread the use of artificial intelligence and other cutting-edge technologies.

At events such as the large consumer electronics show CES in Las Vegas in January and the Mobile World Congress (MWC) in Barcelona in February, it is expected to learn more about 5G soon. Wireless service providers including AT & T and Verizon are already talking about 5G. Equipment manufacturers are pre-testing equipment that works with technology.

Samsung recently demonstrated a 5G smartphone prototype that is expected to run on Verizon and AT & T networks. Many other manufacturers are racing to follow up, although Apple is not expected to be in the initial 5G wave. Analysts predict that the iPhone with new technology will not arrive until 2020. An Apple spokesman declined to comment.

Here is what you need to know.
What exactly is 5G?

Strictly speaking, 5G is a set of technical basic rules that defines how cellular networks work, including the radio frequencies used and how various components such as computer chips and antennas process radio signals and exchange data.

Since the first demonstration of mobile phones in the 1970s, engineers from multiple companies have gathered to agree on a new set of specifications for cellular networks, which are designated as a new generation of technology every ten years or so. In order to get 5G product efficiency, users will have to buy new mobile phones, and operators will need to install new transmission equipment to provide faster services.

How fast is 5G?

The answer depends on where you live, which wireless service you use and when you decide to try 5G.
Wireless chip maker Qualcomm claims 5G peak download speeds can reach 4.5 gigabits per second, but expects an initial median speed of about 1.4 gigabits. This is equivalent to about 20 times the current 4G experience.
5G speeds are particularly noticeable in high-quality streaming video. At Qualcomm’s alleged median speed, downloading a regular-size movie in 5G takes 17 seconds, while 4G takes 6 minutes.
Justin Denison, Samsung’s senior vice president, said that you don’t have to remember to download your favorite TV show of a certain season before you go to the airport, you can download it when you are waiting in line for example.
Is this the only speed that matters?

No. There is another kind of speed, called the lag problem of delay, which may be more important in 5G.
The current response to a command on a smartphone, such as opening a web search, is not exactly instant. Delays of 50 to a few hundred milliseconds are common, in part because signals are usually passed between different operator switching centers; 5G uses newer network technologies and is designed to reduce latency to a few milliseconds. It is also designed to transmit signals more reliably than earlier cellular networks, which today often lose data in some non-essential uses, such as watching movies on mobile phones.

This improvement can bring many benefits, notably in areas such as virtual reality. High-quality virtual reality applications are now generally equipped with bulky headgear, wired to a nearby personal computer that generates 3D images. Cristiano Amon, president of Qualcomm’s semiconductor business, said that with 5G, it can be wirelessly connected to other machines, allowing users to move freely and make it easier to develop eyewear the size of eyewear.

Patrick Moorhead, an analyst at Moor Insights & Strategy, said that in the field of augmented reality (AR), people can use a smartphone camera to aim a football game, While watching the live video on the display, you can see the superimposed player statistics or other data.

The impact of 5G also touches medical and other areas that increasingly rely on high-speed connectivity.
“When it comes to telesurgery or connected cars, you don’t want too much delay,” said Fredrik Jejdling, executive vice president of Ericsson, a mobile device maker.

When will 5G arrive?

For smartphone users in the United States, the answer seems to be in the second quarter of 2019; the exact time is uncertain.
According to the timetable compiled by Qualcomm, the countries that are expected to launch 5G technology after the United States in 2019 include the United Kingdom, Germany, Switzerland, China, South Korea and Australia.
Can consumers fully enjoy the advantages of 5G?

Verizon and AT & T will use for the first time in their 5G products high-frequency technology called “millimeter waves.” With this, wireless service providers can send and receive data at high speeds, but signals can travel a limited distance. Therefore, the two operators are expected to first target densely populated areas-in the words of AT & T’s Andre Fuetsch, “parts of the city”.

Sprint and T-Mobile plan to start at lower frequencies. Michael Thelander, president of Signals Research, a wireless consultancy, said the result could be a slower initial speed but wider coverage.
However, the full benefits of 5G are not expected to be realized until U.S. carriers upgrade their core switching equipment, which may not happen until the end of 2019 or sometime in 2020.
Should I buy a 5G-enabled smartphone right away?

You need to think about many things. For example, although Verizon and AT & T plan to add low-frequency-based 5G services later to provide wider coverage, the first batch of 5G phones may not work properly under this part of the network. As a result, the 5G signal range of these phones may still be limited.
“I won’t buy a 5G phone until it can support a lower frequency 5G network,” Tyrande said. “For all operators except Sprint, this means at least at the end of 2019, and more likely to be 2020.”
