5G, from the single-dual-mode to the global debate
In 2019, the technological breakthrough that attracts the most attention in the smartphone industry is of course 5G, and the biggest point of contention is undoubtedly related to 5G. As early as this year, I personally experienced the 5G network in the MWC venue, and later participated in many domestic 5G pre-commercial experience activities. We at Sanyi Life once raised such a question. If the current 5G technology is on the speed of networking It is better than a well-built 4G network (LTE-A Pro network with a bandwidth of up to 3000Mbps, which exceeds the current 1000Mbps of 5G). Should we meet the early 5G standard with a huge price and high user replacement costs?
Unfortunately, at that time, our question was not paid much attention by many people. But just a few months later, the controversy about “early 5G” attracted the public’s attention in another form. This is the “5G dual-mode” dispute that broke out in the middle of this year.
In fact, looking back now, the 5G dual-mode controversy is very simple in nature, that is, the operator chose the NSA (Non-Independent Networking) method to build an early 5G network. Most mobile phone manufacturers also generally introduced this to support this. The first 5G models in networking mode. At this time, Huawei, which already has support for NSA / SA dual-mode 5G networking technology, naturally wants to self-promote a wave. This is not only to show its objective lead in 5G technology at the time, but also to help promote SA networking 5G base stations. business.
In all fairness, holding a more advanced technology card in hand, any manufacturer must want to self-promote a wave of change, which is understandable. However, the SA networking technology that was born at the time was declared as “true 5G”, but the NSA networking that has been widely recognized internationally was dismissed as “fake”. Such propaganda methods are not only contrary to the facts, but also not clever. .
Moreover, tests from official institutions have shown that SA is not necessarily faster …
After all, the so-called 5G technology is essentially a fairly large collection. In the case of networking, NSA and SA are just two different implementations under the technology branch of the Sub 6GHz band. In addition to SA and NSA, 5G’s core communication technology also includes millimeter wave, DSS (spectrum multiplexing), 4G and 5G overlay, 5G multi-card multi-standby, etc., so of course we cannot say that all of these Which of the technologies is “true” and the other is “false”. Furthermore, if a 5G mobile phone only supports the NSA and SA dual mode of the Sub 6G band, its competitors not only support dual mode, but also support millimeter wave, dual card dual standby and spectrum Multiplexing, support for carrier aggregation and other technologies, so in this case, who can be said to be true or false?
Because of this, when the time advanced to December of this year, after the release of MediaTek Tianji 1000, Qualcomm Snapdragon 765 / 765G and Snapdragon 865, the previous argument about “supporting SA is true 5G” was almost instantly on the Internet Disappeared without a trace. Instead, the discussion about whether 5G mobile phones can support overseas standards and whether they can go abroad to achieve “5G Global Connect” is obviously a “slogan battle” at the market level, but the technical position of both parties. Now it’s turned upside down, which is quite dramatic.
