At 1:00 a.m. Beijing time on Wednesday, Apple will release the long-awaited new generation of iPhone 12, one of its biggest selling points is the support of 5g technology, but for most people, it is impossible to enjoy the speed. At this conference, “5g” will be the core topic and one of the main selling points of the iPhone 12. Compared with the current 4G LTE technology, 5g’s running speed is 10 to 20 times of that of 4G in theory. However, Boris metodyev, deputy director of strategy analytics, a research firm “On the current network, using the iPhone 12 or any device that supports 5g is like having a Ferrari, but you can only use it in your local village, you can’t drive at 200 miles per hour because the road can’t support that speed,” said Metodiev < p > < p > to this end, analysts say Apple needs to strike a balance when it releases the iPhone 12 in the early hours of Wednesday: it wants to attract consumers to buy, while not boasting too much about the high-speed experience of 5g. < / P > < p > at present, most 5g networks in the United States use low-frequency wireless spectrum (i.e. airspace), which is slower than high-frequency spectrum, but more reliable in long-distance. It may take years to achieve the speed promised by mobile operators. < / P > < p > Although several operators in the United States have deployed 5g networks based on lower frequency bands, the speed is only slightly higher than 4G. In the first half of this year, the rootmetrics division of IHS Markit, a research firm, tested 5g networks in 125 regions of the United States. The test found that 5g network speed of at & T, T-Mobile and sprint is only slightly faster than 4G LTE. < / P > < p > although at & T and T-Mobile both claim that their 5g networks already cover “the United States,” which means they can reach 200 million people in the United States. But in fact, their 5g network coverage is still sporadic, and the data speed is not always fast. Gene Munster, an analyst at Loup ventures, a venture capital firm, said a faster variant of the “mid frequency” 5g is coming out, but it is unlikely to cover three-quarters of Americans before 2025. < / P > < p > in contrast, Verizon’s 5g network using millimeter wave technology is much faster, but it can only be used in parts of 36 cities. Moreover, because of the frequency, the signal will deteriorate rapidly. < p > < p > opensignal, a research company, reported in June that although the connection speed of Verizon 5g users is almost 10 times that of sprint and T-Mobile, the actual average speed is much lower. < / P > < p > another disappointment is that applications that use higher speed (5g) to provide new functionality have not yet been developed. At this stage, industry executives say, it is a “chicken and egg” issue. It should be noted that in the early 4G era, it was Facebook’s mobile app and alphabet’s YouTube that drove interest. “The apps that will dazzle us and really take advantage of the network will only be developed when the network and devices are truly available,” said Morgan kurk, CTO of CommScope, a telecoms equipment manufacturer Analysts say the most motivated U.S. consumers to buy 5g phones will be those who really need a new smartphone and those who want to protect their investments. Geoff blaber, vice president of CCS insight, a research firm, said: “if you’re buying a phone you want to use for three years, you want it to support 5g.” “To be sure, there’s not much that can be done on a 5g iPhone and not much can’t be done on a 4G iPhone,” Braber added The release and download schedule of Microsoft Flight Simulation varies from region to region
