The phones are expected to be visually different from past years’ models, giving users another reason to upgrade. 悲觀者略以:
Then there’s mid-band 5G, which does promise to be significantly faster and cover wide regions, but is still under construction. T-Mobile said this summer that it hoped to build its mid band network “over the next few years.” The biggest jump in speeds will come from the variety of 5G sometimes called millimeter wave or ultrawide band. But in the United States, millimeter wave is only available in certain markets and has limitations about how far it can be transmitted. While carriers are expanding quickly, the new iPhones may only be able to reach their full potential in a handful of regions. “Not all 5G is created equal, which has led to marketing noise from carriers regarding 5G performance and deployment,” Loup Ventures founder Gene Munster wrote in a newsletter in September. “In the end, both consumers and businesses are left unsure as to the timing of the 5G transformation.”
Consumers won’t know until Tuesday if Apple will support all three versions in all its phones, or if it will offer different models sold in different regions based on which countries have the most developed 5G networks. 目前5G的速度只有4G的1.8倍
