Band support

nRF9160 supports multiple LTE frequency bands that are listed in nRF9160 certifications on the Nordic Semiconductor web page.

As the electrical size of the antenna sets limits to the antenna bandwidth, it is recommended to select an antenna that supports only the operational bands of the device and then optimize the antenna performance for the used frequencies. An antenna with smaller electrical size has a narrower reachable bandwidth and lower radiation efficiency. If wide bandwidth and small physical size are required from the device, antenna tuners may be beneficial, because antenna input matching can be optimized for the frequency of operation at a given time. The antenna can also be designed to have tunable resonant frequency. Antenna suppliers and design houses provide solutions for size-limited antennas. nRF9160 provides control for external antenna tuners. For more information, see External RF control.
