b53の仕様は、「TDD LTE over WiFi、2.4835GHz〜2.495GHz」となっています。
OKAY. I think I may have gotten to the bottom of this "iPhone 13 will include satellite connectivity" rumor, and it could be "iPhone Math" levels of game-of-telephone. The key: Globalstar.
Qualcomm's x65 modem supports b53/n53 but the x60 does not. However, the Qualcomm modem in the iPhones may be an … erm, x60-and-a-half. In other words, it could be an x60 + b53/n53. This DOES NOT IMPLY TALKING TO SATELLITES. It's a ground based band G'star wants to enhance LTE
Bonus: The "iPhone Math" reference is from when the iPhone 6 came out. A translation error from a Chinese web site misread "iPhone 6 Plus" as "iPhone 6 Math." One of my favorite errors EVER.
