Apple today released the iPhone 15 series of new devices, a total of four, respectively, iPhone 15, iPhone 15 Plus, iPhone 15 Pro and iPhone 15 Pro Max. These new models are equipped with a USB-C interface and the spirit of the island, and the Pro version there are more special features, such as the A17 Pro chip, lightweight titanium frame, customizable Action buttons, 5x optical zoom on the Pro Max version, Wi-Fi 6E support, 8GB of RAM, and more.
Apple’s official website shows that only the U.S. version of the iPhone 15 series supports millimeter-wave 5G bands. This has been the case since the iPhone 12 series was released in 2020.
Millimeter wave is a 5G frequency that delivers ultra-high speeds over short distances and is suitable for densely populated urban areas. By contrast, sub-6GHz 5G is typically slower than millimeter wave, but the signal travels farther and is better suited for suburban and rural areas. All iPhone 15 series support sub-6GHz 5G except in the U.S. Currently, sub-6GHz networks are still more common than millimeter-wave networks in countries where 5G has been rolled out, with Australia, China, Japan, and Singapore among the countries that have deployed millimeter-wave networks so far.
Pre-orders for the iPhone 15 series will begin this Friday, with the device officially going on sale on September 22nd.
