The first enforceable 5G new air interface (5G NR) specification was successfully completed at the 3GPP TSG RAN plenary meeting in Lisbon on December 21, 2017. This signals that now that you are shouting about 5G it should be No one will question you, that with the advent of this wave of hot tide, there will always be some companies in the industry more attention than others, because they are the industry leader, such as today's article to say Qualcomm.
At this stage, the words of Qualcomm, presumably you will find that in addition to the Snapdragon 845 this star product, many people will individually refer to the modem, which will speak of X16, X20 and even the latest technology X50 and other three generations of products, that as a 5G Onlookers onlookers and participants in the process, we may wish to follow this line of thinking to see what the three generations of Qualcomm MODEM in the end what kind of evolution of the road.
5G Compared to 4G, many people's first reaction may be faster, although there are other features such as low latency, high reliability, large scale, but the first time to stimulate people, which may be 10Gbps 100Mbps relative to such a huge 100-fold data difference.
We take the Qualcomm modem as a comparison, which Snapdragon X50 is undoubtedly the leading product of the era of the 5G.October 18, 2016, Qualcomm announced the introduction of the Snapdragon X50 5G modem, becoming the first release of the commercial 5G modem chipset solution Program by supporting 800MHz bandwidth, the Snapdragon X50 5G modem is designed to support peak download speeds up to 5Gbps, a year later, on October 17, before other companies saw their backs, Qualcomm has moved a long way further , Based on the X50 5G modem chipset, Qualcomm successfully implemented the first 5G data connection in the world and achieved a transmission speed of 1.25Gbps at the millimeter-wave frequency band of 28GHz. After crossing the 1Gbps mark, it is believed that as technology continues to improve Mature, 5Gbps target just around the corner.
At the same time, more than just a separate chipset, Qualcomm even introduced the first 5G prototype prototype reference machine. You are still studying the technology, I realized for you to see, you do not know how to design the terminal, I made the finished product You reference, Qualcomm ah Qualcomm, but you too too Joseph, but we consumers like ~
X50 corresponds to 5G, X16 and X20 is corresponding to the 4G? Yes, but not exactly right .If only for its own basic 4G, Xiaolong 620 integrated X8 LTE, its 300 / 100M uplink and downlink rate has fully meet the 100Mbps 4G basic rate of this To explain in detail, you need to talk about the evolution of the network standard.
4G LTE, of which the original intention of LTE is long term evolution (long term evolution). Since 4G LTE is officially commercialized, as its version is constantly changing, itself is constantly evolving, and the rate and other landmark parameters are constantly evolving. Gigabit LTE is its stage of evolution of the product now Gigabit gigabit LTE is like a huge gap between 4G and 5G bridge.The main purpose of this bridge is to bridge the bridge to achieve the 4G to 5G smooth transition.
According to 3GPP's plan, the 5G standard is divided into two types: Non-Standalone (NSA) and Standalone (SA). As mentioned in the beginning of the article, December 21, the first 5G NR The 3GPP standard protocol version not only provides an NSA solution for 5G deployment, but also completes the common part of NSA and SA.Now we are discussing more about the non-independent networking part, which is simply relying on 4G to develop 5G, And gigabit LTE is to raise the LTE rate close to 5G based on the degree to ensure smooth upgrade, but also can promote operators to use and upgrade existing resources to accelerate the 5G deployment.Even in the 5G SA large-scale After the deployment is completed, gigabit LTE can also be used as a supplement under some conditions.
So corresponding to Qualcomm's modem, X16 and X20 more is the exploration of this stage.
The X16, released in February 2016, has a theoretical download speed of 1Gbps and actually downloads 979Mbps in cooperation with Telstra, the Australian telecoms company. At present, the Snapdragon 835 processor with integrated X16 modem is already large Scale equipped with the flagship phone in the factory, such as this year's rave reviews Samsung S8. 2017 year, gigabit LTE indoor, outdoor test, rate verification are all major carriers news, which In a single step, Qualcomm can be said to have walked in front of everyone.
A year after the release of the X16, February 21, 2017, Qualcomm officially released the second-generation gigabit product at the 5G Summit in China. The X20 modem, like the X16, was first born as a stand-alone chipset and later Integrated within Soc. And on the 5th of this month Snapdragon Snapdragon 845 released on the summit, has integrated the X20 modem as we will actually use the next period of the latest technology, its characteristics are as follows:
- Supports 1.2 Gbps gigabit LTE Category 18
- Support for Accessibility Assistance (LAA)
- Support Citizen Broadband Wireless Services (CBRS) shared spectrum
- Dual SIM Dual VoLTE (DSDV)
Although the last three have the same impact on the actual experience, but today we focus on the first, theoretical download speed of 1.2Gbps. In cooperation with Nokia test, Qualcomm based on the X20 modem achieved 1.175Gbps download speed, which can Said that it is steadily across the gigabit level to ensure that we can use Qualcomm's technology to experience the best network services operators can offer before the deployment of the 5G SA network is completed for the next year or even 2019 , Of course, also need to provide operators can provide.
From X16 to X20 and then to X50, not only reflects the leadership of Qualcomm technology, as well as its important guidance in the development of the industry, the volume of business, has the ability to a certain extent, the related industries Positive development, and want to take this step, play a positive role in guiding, the need may be much more than the technology itself. Qualcomm 5G evolution now go very fast, very good, that when the road Can go to the second half, we may wait and see.
Finally, the last two knowledge that is not knowledge, we look at the play, relax and relax.
① 1MBPs = 1024Kbps = 1024 / 8KBps = 128KBps, so if you want to replace the data in the text you are more accustomed to the download speed, you can simply remove 8, the remaining practical factors will have a certain impact, not to repeat them here.
A slot point, LTE also said that the meaning of long term evolution, it is bound to evolve it Well, the subsequent emergence of LTE-A (LTE Advanced), more advanced LTE can understand, but now, there has emerged LTE-A Pro , The amount of advanced advanced professional LTE? This naming style, and now mobile phone will always be Plus, Pro's suffix, there is no high where to go thing.
