IPhone 12 Can Act As 5GHz Wi-Fi Hotspot, 5G Boon

Apple’s iPhone 12 series sports an enhanced hotspot mode that supports 5GHz Wi-Fi connectivity, greatly expanding the usefulness of handsets amid a global construction of 5G cellular networks.

As noted by several reports on Twitter, including that of Zollotech Aaron Zollo, iPhone 12 devices include the new Personal Hotspot feature which serves as an upgrade from previous iPhone models. Before the iPhone 12, Apple’s smartphone was able to connect to the 2.4 GHz and 5 GHz bands, but limited the tasks of access points to the 2.4 GHz band.

The capability is not explained in Apple’s marketing materials, nor is the functionality explained in iOS. Zollo, however, confirmed that a new “Maximize Compatibility” option manages switching between the two bands.

“Internet performance may be reduced for devices connected to your access point when they are turned on,” according to the feature description.

While the warning is vague, Zollo says the setting moves the Personal Hotspot to the 2.4GHz band to allow compatibility with a wider range of devices. Disabling the option likely locks iPhone 12 handsets into 5 GHz Wi-Fi mode for faster data transmission.

The addition is expected to prove beneficial for users in areas where 5G cellular connectivity is being rolled out. Currently, most locations with 5G are limited to bands below 6 GHz with speeds comparable to existing 4G LTE networks. Some urban areas, however, get a taste of the fast mmWave bands and will be able to take advantage of the iPhone 12’s faster hotspot.

Apple’s iPhone 12, iPhone 12 mini, iPhone 12 Pro, and iPhone 12 Pro Max support mmWave, but only in the U.S. To enable protocol access, home iPhones incorporate a special mmWave antenna window that resides in a cutout below the side button.
