5G: COVERAGE AND DEVICES
The next-generation of telecom networks (fifth generation or 5G) has started hitting the market end of 2018 and will continue to expand worldwide.
Beyond speed improvement, the technology is expected to unleash a massive 5G IoT (Internet of Things) ecosystem where networks can serve communication needs for billions of connected devices, with the right trade-offs between speed latency, and cost.
5G is all set and ready to transform industries and society as we know them. Evolving networks to cater for everything from smartphones to robots on factory floors requires high performing, highly reliable connectivity. That’s why we’ve built a flexible Ericsson 5G platform, enabling service providers to embrace opportunities and challenges, and offer new services for a whole range of new users and industries
5G NETWORK COVERAGE
#5G is estimated to cover 60 percent of the world’s population in 2026.
Key findings
By the end of 2021, 5G coverage is expected to reach 15 percent of the global population, up from 5 percent at the end of 2019, and is forecast to grow to 60 percent in 2026.
The most extensive coverage build-outs have been in the US China, South Korea and Switzerland.
Despite the impact of COVID-19, 5G is still expected to be the fastest deployed mobile communication technology in history.
Momentum continues in the build-out of 4G (LTE) networks. Global 4G population coverage will be over 80 percent at the end of 2021. and is forecast to reach around 95 percent in 2026. 4G networks are also evolving to deliver increased network capacity and faster data speeds. There are currently 795 commercial 4G networks deployed. Of these, 324 have been upgraded to LTE-Advanced, and 41 Gigabit LTE networks have been commercially launched.
HOW FAST IS 5G ?
Speed is the benchmark for wireless network performance. Also known as bandwidth, data transfer rate, data rate, or connection speed, it refers to the amount of digital data exchanged between two devices via a specific channel in a given period.
Network speed is generally measured in bits per second (bit/s). Bit stands for binary digit. With the larger volumes of data supported by 5G speeds. data transfer rates are expressed in kilobits (kbit/s), megabits (Mbit/s) and in future, even gigabits (Gbit/s) or terabits (Tbit/s).
Deutsche Telekom tested a 5G network live at this year’s IFA. A speed of three gigabits per second was measured. Under ideal conditions. the 5G speed should in future reach up to 10 Gbit/s, the equivalent of a 20-fold increase.
Just how fast 10 Gbit/s really is can be demonstrated by a simple example. A user takes around 13 minutes to download the content of a DVD (4.7 GB) over a DSL line with a bandwidth of 50 Mbit/s. A 5G-enabled smartphone or laptop could download the content of an entire DVD over a mobile 5G data link in just four seconds in the best-case scenario.
5G technology involves more than just speed though. Availability and reliability are other decisive factors.
SUPPORTING DEVICES OF 5G
Plenty of 5G phones are being put out now, two years after the first such handset was released - at this point, it'd be surprising for a new device launched to be 4G-only.
5G is the next generation of mobile data connectivity, bringing super-fast speeds and improved connection reliability and stability over 4G, making it great for tasks like online gaming, streaming movies and downloading large files quickly.
We've compiled this list of the best 5G phones so, if you're looking for one, you know what to opt for. This round-up isn't just a replica of our standard best smartphones guide we've considered the key uses of 5G, and brought you a list that focuses on these key points. The following round-up is broken down into categories to fit the reasons you might be looking to buy a 5G phone.
Each of these entries has a 'best' model and a 'runner up'. This is so you have a choice even within the categories, which is especially important given that not all of our best phone picks are available in the US.
At TechRadar we test every new 5G phone that comes out, so we've got a good idea of how they all run, work, and compare and we've used that knowledge to create this buying guide to help you work out which 5G phone is best for you.
This guide has recently had a shake-up too, with the addition of the Samsung Galaxy S21 Ultra. There might be more new additions arriving soon as well, with the Oppo Find X3 OnePlus 9 and more all expected in the next few months. So if you can wait for a little while longer, your choices might be very different.
FIRST COUNTRY TO LAUNCH 5G ?
South Korea has launched the world’s first nationwide 5G mobile networks two days early, its top mobile carriers said on Thursday, in a late-night scramble to be the first providers of the super-fast wireless technology.
Three top telecom providers SK Telecom, KT, and LG Uplus began their 5G services at 11 pm local time Wednesday despite previously announcing the launch date would be April 5.
Hyper-wired South Korea has a long reputation for technical prowess, and Seoul had made the 5G rollout a priority as it seeks to stimulate stuttering economic growth.
According to the London-based Global System for Mobile Communications, “The technology is crucial for the future development of devices such as self driving vehicles and is expected to bring about $565 billion in global economic benefits by 2034”
