The adoption of 5G technology had a significant increase in 2020 in both networks and devices despite the uncertainties caused by the COVID-19 pandemic. 220 million 5G subscriptions are forecast worldwide at the end of 2020 The data comes from the latest Ericsson Mobility Report report.
This statement also underlines that 3.5 billion 5G subscriptions are expected by the end of 2026. In this sense, it is estimated that these connections will occupy more than 50 percent of mobile data traffic at that time. 5G is a technological advance that will directly impact different industries: from connected vehicles to the use of robots, through smart cities and even tele-assisted surgeries.
Benefits of 5 G
speed 5G implies an increase in speed of up to 100 times compared to 4G and 4G +. The variations are wide because the improvements in this index depend to a great extent on the deployment of the network and the technology used. The download speed of 5G, when it reaches its maximum point of maturity, will be up to 20 Gbps, while the average in 4G is 16 Mbps and in 4G + in the best case it is 1 Gbps. In a study by Open Signal , released in October 2020, an analysis was made of the 5G experience that exists in different parts of the world and they concluded that, on average, the 5G download speed is between 5 to 6 times faster than 4G, but there are big differences when analyzing by country
In this sense, for example, in Thailand the fifth generation network offers 15.7 times faster but this new standard in the Netherlands is barely 1.6 times faster than 4G . On the other hand, users in Saudi Arabia have the fastest average 5G download speed: about 377 Mbps
latency This technology significantly reduces latency (the time between sending an order and executing it): it goes from the tens of milliseconds of 4G to just one millisecond.
Improved coverage: more connected devices
The 5G promises better coverage, less saturation and therefore a more optimal connection experience. In turn, the network offers other benefits, such as the possibility of supporting up to 100 times more connected devices than 4G allows at the same time, and it can support a million devices per square kilometer
Lower power consumption
The new standard allows a 90% reduction in energy consumption. It also offers longer battery life, particularly in low power devices
These benefits directly impact industries such as connected vehicles where speed and reduced latency is key to driving safe. “Every year 1.35 million people die from accidents and 90% occur from human failure. Technology makes it possible to help and greatly reduce this. 5G can help reduce accidents in a concrete way ”, analyzed Helio Akira Oyama, director of Product Management at Qualcomm, in an event that the company held in 2019 and in which Infobae participated .
At the World Congress de Móvil de Barcelona in 2019 also showed how tele-assisted surgeries could be performed thanks to the speed and low latency provided by the fifth generation network. This allows a doctor to direct an operation from a distance, without cuts or interruptions in the connection.
In robotics, speed this new standard is also key because it allows better performance of robots in the industry. This would allow its use to be extended, which would generate a positive impact on productivity
5G is key in the development of smart cities that involve the deployment of sensors everywhere to collect information that is then processed and analyzed to achieve greater safety, fewer accidents, greater punctuality in public transport and less energy consumption, among other issues.
The network will allow the connection of billions of low complexity IoT devices. In short, the speed and low latency that 5G promises in the processing of all this information is fundamental.
To understand what the deployment of 5G is like, it is necessary to understand how the infrastructure deployment is progressing. On the one hand, there are the Standalone (SA) networks that are new and independent of the current 4G infrastructure; and on the other, Non-Standalone networks (NSA) that are based on the existing 4G infrastructure. Specifically, it means that the same servers that are already used for 4G are used, but connected to new access networks.
There are several countries that began to deploy the first phase of 5G, that is, through NSA networks. This is the case of several regions in Spain , for example, as well as in other countries in Europe , Latin America and Asia . With this type of technology, speeds of 2 Gbps, greater stability and latency of about 15 milliseconds are reached on average.
But there are also countries that have already started with the second phase of 5G deployment, that is, SA networks. Such is the case in some regions of the United States , South Korea and China . As mentioned in Ericsson's Mobility Report, the deployment of NSA and SA is expected to coexist for several years
5G needs spectrum within three frequency ranges to offer coverage and support in different use cases, as explained by the GSMA , an organization that brings together 800 mobile operators and more than 200 related companies:
1) Spectrum below 1 GHz serves to expand high-speed 5G mobile broadband coverage in urban, suburban and rural areas , and for IoT.
services 2) The 1-6 GHz spectrum offers good coverage and capacity for 5G.
services 3) The one above 6 GHz for ultra high speed mobile broadband.
Millimeter wave opens new opportunities for 5G networks
The millimeter wave or "mmWave" is the short wavelength spectrum between 24 GHz and 100 GHz, which has the ability to deliver wireless services in gigabits and n areas with very high data demand
While most 5G networks have so far been deployed in a variety of spectrum bands, even below 1 GHz and between 1 and 6 GHz, the 5G New Radio (NR ) is the first generation of mobile technology to use the millimeter wave spectrum . This spectrum is generally more suitable for short-range transmissions and can provide a number of benefits, from expanding coverage at the edge of the network to optimizing capacity and backhaul.
“ The wireless mobile communications industry requires spectrum in low, medium and high bands to allow 5G to unleash its full potential . Millimeter wave technology is important for the advancement of 5G networks, as it provides higher data speeds and much higher capacity compared to 4G LTE, ”said Chris Pearson, President of the 5G Americas association, in a statement released by the entity
Countries in Latin America with 5G
There are several countries that have piloted 5G in the last two years, but the network is operational only in some countries such as Uruguay, Puerto Rico, Brazil, Suriname and Colombia, although
In Uruguay, the 5G network was switched on in April 2019 and uses the 28 GHz band, while in Puerto Rico and the United States Virgin Islands the 600 MHz band is used. The latter was added in December 2019. The same way as the 5G networks in Trinidad and Tobago and Suriname where they announced launches for services such as fixed-wireless access, as mentioned in a Forbes article. The most recent deployments of 5G in the region were in Brazil and Colombia
What is abundant are the pilot tests: during 2019, at least 30 5G tests were carried out in 12 countries. And in fact, tests have been carried out for at least 2 years in different places in the region such as Argentina, Peru, Mexico, Dominican Republic, Ecuador, Costa Rica and Honduras, among others.
