  > LTE Band 53 is a part of the TDD (Time Division Duplex) LTE spectrum that requires only a single frequency band for both the uplink and downlink. LTE Band 53 has a frequency range from 2483.5 - 2495 MHz with a bandwidth of 11.5 MHz. From: https://www.everythingrf.com/tech-resources/lte-bands/lte-band-53 https://www.everythingrf.com/tech-resources/lte-bands/lte-ba... Quite impressive they can receive that on the satellite with 1W (guess) of power and a not very directional antenna in the iPhone.
