What is and how does 5G DSS work?
5G DSS smartphones may or may not support standalone 5G; see if your device will support fifth-generation internet, and What is and how does 5G DSS work?
“Smartphone with 64 MP main camera, 6 GB RAM, 128 GB storage and 5G connection ”. It’s the description of some specifics of many cell phones out there. The fifth-generation network is stamped in the name of the devices as a highlight to make the cell phone more attractive to consumers. But, does 5G really exist? If not, what do the telephone companies sell instead of the network? We explain it to you.
To start answering the above questions we need to understand what 5G is. The new generation of the internet has more capacity to carry data than the previous technology, 4G. With the fifth-generation network, latency is considerably reduced, meaning that the response time is shorter and is between one and four milliseconds. Such instant access allows the connection of several devices simultaneously. This network of connected equipment is what we call the Internet of Things or IoT.
5G network highlights:
– High download and upload speed
– Minimum response time of up to 1 ms
– Support for multiple connected devices
– 8K streaming
South Korea was the first country to offer standalone 5G, launching the network in 2019. Later, countries such as China, Japan, Australia, Germany, Switzerland, and the United States began to advance in the deployment of the technology. The fifth-generation internet is available here in a different way.
With the pre-launch of the first 5G smartphone, comes the arrival announcement of the 5G DSS technology. The acronym is Spectrum Dynamic Sharing and comes from Dynamic Spectrum Sharing. This type of network is a different version of 5G technology, and it is the one we use in the country for now.
The 5G DSS uses the 5G NR (New Radio) standard in the NSA (non-standalone) version. This means that the connectivity:
– depends on an LTE network to function
– shares 4G and/or 3G frequencies
– has fifth-generation technology features not yet been implemented
– reaches speed slower than the “pure” standalone 5G
As a preview of the standalone 5G, which uses the spectra of other technologies already auctioned, the 5G DSS can be offered by telephone operators. Although the network does not deliver the same power as 5G, it has its benefits. The main one is the increase in connection speed, which reaches 400Mbps, that is, up to 12x faster than 4G. It’s not as fast as 1 to 10 Gbps 5G can achieve, but it’s what’s available to us.
Also called the first step to “pure” 5G, 5G DSS does not work on smartphones that only support the 4G network. Likewise, the technology that transits through the fourth and fifth-generation bands does not guarantee connectivity with devices compatible with the traditional 5G.
An example of this is Motorola’s Edge family, a line in which one of the firsts cell phones with 5G technology was launched. While the traditional model supports 5G DSS, the Plus version is only compatible with the standalone 5G network. On the company’s website, the notice of the most turbocharged device reads:
“Motorola Edge+, Motorola’s top-of-the-line smartphone, is ready for the future. It supports 5G technology already available in Canada, Mexico, and some European countries. In other countries, it will work on the future frequency of 5G technology that will still be auctioned and implemented in the country.”
In summary, 5G smartphones may or may not support the 5G DSS. And how can you know if your device supports fifth-generation connectivity?
Currently, 26 5G smartphones are in the Certification and Homologation System (SCH) of the National Telecommunications Agency (Anatel). This means that cell phones have standalone 5G technology and/or also 5G DSS. Check out the models below:
All of the above devices are compatible and certified with the 5G DSS, which we currently have, and will also work with the new 5G frequencies that will be auctioned. Xiaomi’s POCO F3, Mi 11, Mi 10T, and Mi 10T Pro smartphones, which appear in Anatel’s system, appear only as 5G DSS, as the 5G bands are not in fact yet included in the 3GPP standardization organization’s testing standard. This may change, but the certificate will be updated with new information.
However, even with the arrival of the standalone 5G, the 5G DSS will continue to operate , as this is a way to expand not only the network’s reach faster, but also an opportunity to offer a better quality of service.
