According to foreign media CNET, it is now certain that 2020 will be a garbage year for mankind, but it will be a fruitful year for new mobile phones, cameras and game consoles. In September alone, a series of new products were launched – including the Xbox series X and ps5, Sony’s new a7s III mirrorless camera, Samsung’s Galaxy note 20 ultra and Galaxy S20 Fe, and a series of new products from Amazon. < / P > < p > with the end of technology September, we are entering October, and the most anticipated new product is undoubtedly Apple’s next-generation iPhone, which is rumored to be called the iPhone 12. The leaked news and rumors indicate that the next generation of Apple phones will launch a series of new features, including high refresh rate display, larger size and lidar. But the most important adjustment is not the camera or the expected A14 processor, but its 5g support. < / P > < p > this means that the biggest features of the iPhone 12 will be largely out of Apple’s control and firmly in the hands of at & T, T-Mobile and Verizon. For users, the 5g experience on the iPhone 12 will depend on the carrier and place of residence they choose. For apple, this is an unusual position. Apple is known for its persistence in building almost everything from hardware to software. In contrast, 5g in the United States is a mixture of hype, expectation and harmony. Depending on the carrier, 5g has different frequencies, some of which are incredibly fast, but others are not always connected to the user’s phone. Although other frequencies have long connection distance and stable connection, they are not much faster than 4G LTE. Some parts of the United States have 5g networks provided by the three major operators in the United States, while others have no coverage at all. < / P > < p > does this mean that 5g will determine the success or failure of the iPhone 12? In terms of sales, of course not. Apple could sell millions of new iPhones. But that doesn’t mean that everyone who buys an iPhone 12 can enjoy the wonderful experience of accessing 5g networks. For many people, on their new iPhone, they may try to have a bad 5g experience. < / P > < p > when it comes to 5g, things get more complicated because not all 5GS are the same. For example, ultra-high-speed 5g and mid low band 5g require different antennas, which means that the same iPhone needs multiple models. The fragmentation of 5g is also a very difficult problem. < / P > < p > in that case, why should Apple risk 5g? The company had to. Even if the road is not yet fully paved, 5g will be the way for most of us to access mobile data in a few years. Another reason is that 4G LTE is a huge safety net. IPhone 12 users can connect via 4G LTE even if their community doesn’t have a 5g wireless network. But if the same person spent a lot of money on a 5g iPhone and the result is no 5g signal or poor signal, it is really a pity to be honest. Global Tech
