12 Jun The Beginnings and How to Go About Going 5G Wireless
The conversions between 1G, 2G, 3G and then 4G were all well acknowledged by consumers. Now with the enthusiastically awaited advent of 5G wireless (which is actually still quite a few years away), we’re on the tip of another industrial revolution in the world of telecommunications, information technology and wireless infrastructure.
The G in 1G, 2G, 3G, 4G and 5G means a generation of wireless technology. The line between generations has technically been defined by transmission speeds and marked by a break in encoding methods. These breaks also called “air interfaces” mark the point where the device is no longer compatible with the previous generation.
1G was analog while 2G technologies were the first generation of digital cellular technologies. 3G technologies brought speeds from 200 kbps to a few megabits per second. The current 4G tech like LTE is now climbing up to hundreds of megabits to even gigabit-level speeds.
5G introduces 3 new aspects to the table. Greater speed for bigger data communication, lower latency (or less lag time), and ability to connect to more devices at once. This especially for smart devices.
What is 5G?
5G, set to launch in the market by 2020, is fifth generation wireless broadband. That promises speeds 20 times faster than today’s 4G LTE cellular networks. According to the 802.11ac standard, 5G is actually an umbrella term that represents a multitude of technologies. Coming together like massive multiple-input multiple output techs. Also beam forming, millimeter waves, full duplex and small cells.
Changing our experiences with 5G
5g wireless systems are enhanced networks that will provide superior speed, lesser latency and the capacity to connect several devices at once making it a gateway for enhancing the Internet of Things. It will intensely increase the speed at which data is delivered across the network. Making it easier for people to download and upload big files and support thousands of internet-linked devices.
5G is going to be vast industrial shifts that will initiate fundamental changes in our communications infrastructure. It does not just involve faster internet but a whole transformative experience in the way we live. 5G wireless will make an impact much like how the invention of handsets and smartphones changed our lives and the world.
How will 5G Wireless Work?
5G networks will operate in a very high-frequency band of the wireless spectrum, most likely between 28 GHz and 300 GHz, in what’s known as the millimeter wave spectrum.
Millimeter wave or mm wave bands are high band spectrum waves that are easily tempered by weather, foliage and buildings. They have been previously utilized in back end and limited fixed wireless applications. With the recent development of multi-antenna (massive MIMO) ranges and beam forming techniques. These fragile frequencies can now be used for blazing-fast facilities.
Earlier this year at the Mobile World Congress in Barcelona, the consensus was that 5G mobile on mm wave would have a range of 100 to 200 meters. Therefore a should be installed in every metric. 5G networks are more likely to be systems of small cell sites. That’s the size of home routers rather than towers to make expanding network capacity easier. The more cells you have, the more data you can put into the network.
5G networks need to be more intelligent than previous systems, as they’re juggling a bigger quantity of different smaller cell sites. Even with current macro cell sites, 5G should still be able to boost its capacity through advanced antenna technologies.
Poised to be the first to roll out 5G reports testing speeds at 1Gbps and faster at closer range. Millimeter wave signals however can be blocked by glass, concrete, and foliage in beaming to the home scenarios.
There are ways to expand range to 5G though by using lower band as coverage. It will increase range but decrease overall speed. SK Telecom in Korea plans to use 28 GHz signal repeaters as a way to double the range of 5G radios.
For the United States an increased deployment of mmWave small cell units to fill in coverage gaps. The Federal Communications Commission has partnered with government units to ease public utility access to 5G operators in order quicken small cell installations. The 28 GHz spectrum in the America is expected by November 2018.
For a 900 feet city block, this means every block would need one 5G cell unit installed. This is bound to lead to many concerns from residents as 5G moves from hype to reality.
5G won’t just be about higher speed and capacity, but more about new services, facilities and applications that are enabled because of it. This includes the flood of IoT devices and smart cities that demand require the low latency and speeds of 5G.
To illustrate, 4G speeds currently max out at about one gigabit per second. 5G will upsurge download speeds up to 10 Gbps, meaning you can download a full HD movie in seconds. It will also reduce latency significantly, like 1 millisecond latency, meaning you can watch HD streams smoothly real time.
4G is still developing and the fastest possible speed theoretically is currently close to 1Gbps. However in actual testing and commercial use, we’ve only reached up to 425 Mbps on 4G LTE. Theoretically, 5G could deliver maximum speeds in the region of 10s-20s of gigabits per second with actual testing and commercial use probably half of that speed.
The cloud is going to play a much more important role in our lives. With requirement of smartphones to perform supercomputer-like tasks.
Cloud computing on phones could go beyond just storage with the 5G speeds. But may also be used to run apps and games. With the data essentially being processed on remote servers then simply streamed to our phones, it helps the phone to maintain its mobile size and lightness.
Given the size of 4k, 8k, VR and holographic content, media will likely be streamed rather than downloaded. Theoretically that could level out performance between low and high end phones if even cheap phones could offload computing tasks to remote devices with a 5G connection.
Remember those mmWaves discussed earlier? On 5G, each wave will deliver more data at higher speeds. The only disadvantage is that they don’t travel as distant as the lower-frequency waves in 4G networks . And that’s something that 5G developers like Qualcomm and Intel are working to fix.
When will this be ready?
Expect to see 5G wireless in the market around late 2019 to 2020. 5G networks are likely to start rolling out in 2020, so 5G handsets will probably start becoming extensively available for the public by then. Strategy Analytics forecasts that by 2022, ten million 5G handsets will have been sold internationally, and more than 300 million by 2025.
Trial phones are most likely to launch by the end of 2018, but you’ll still need a 5G mobile network to actually use them. They’re also likely to have beta issues like unstable connectivity, short battery life, and no transmission to 4G networks.
Being the new and latest tech, they will also probably be very expensive. So waiting for the next harvest around 2020 wouldn’t be such a bad idea. Most of the 5G phones by then are likely to be limited to Japan, Hong Kong and South Korea, with 2021 anticipated to be the big year for 5G phone launching in the UK.
5G was the talk of the town at the recent Mobile World Congress (MWC) in Barcelona, Spain. Qualcomm, the maker of Android’s Snapdragon chip.
They demonstrated its X50 chip speed of 4.51Gbps. The X50 is ready to be put into 5G phones, and Qualcomm has already signed up phone manufacturers. Such as LG, Xiaomi, Sony Mobile, Oneplus, and HTC. Qualcomm director of marketing, Sherif Hanna says that Japan, South Korea, and Australia will be in the first wave with 5G network operations in early 2019. China Mobile will follow in the second half 2019.
Meanwhile, chief executive of Huawei, Richard Yu, unveiled in his keynote speech the Balong 5G01 5G-ready chip exclusively for Huawei 5G devices. He also teased that the company will launch its first 5G smartphone in the second half of 2018.
Although that release date is way ahead of when 5G networks are available, it’s a sign that the phone makers are a go.
5G networks are already under way in Hong Kong. While several cities in the United States are expecting Verizon and AT&T 5G phones late this year.
Unless Samsung or Huawei springs a surprise towards the end of this year, they won’t have product to ride on the early-launch wave. Cloud computing will be very accessible in the 5G era. The fast connection to the cloud storage means that there might not be a need for much flash storage on mobile devices. Battery efficiency and how phones can easily offload data to the cloud is still to be worked out on the first-generation 5G phones.
Phones will be the first to benefit from 5G, but computers and IoT devices will follow as well. SK Telecom has unveiled a 5G tablet, while Intel’s booth at MWS showed a 5G-capable laptop computer. Dell, Lenovo, HP and Microsoft have all devoted to producing 5G laptops with Intel by 2019.
Internet service providers are moving at a rapid pace to deploy 5G network infrastructure for the coming of 5G. Verizon expects to start deployment in 2018, much earlier than the expected 2020 5G adoption date. Other operators, such as Sprint, AT&T, and T-Mobile, already shared their aggressive 5G rollout plans at the 2018 MWC. For more Internet providers and services, visit www.xyzies.com.
