+BAND_GROUP_INDEX
+   The band group index defines which RF frequencies the modem will operate on.
+   This is configured before the modem is activated.
+   All nRF91 series devices with DECT NR+ PHY support has support for band index 0.
+   DECT NR+ band 4 (band index 1) is supported by the nRF9151 LACA A0 SiP for R&D evaluation purposes.
+   The nRF9151 LACA A0AB SiP will be qualified for DECT NR+ band 4 support.
+   The band group index 0 and 1 can be selected by enabling the :ref:`CONFIG_BAND_GROUP_INDEX_0 <CONFIG_BAND_GROUP_INDEX_0>` and :ref:`CONFIG_BAND_GROUP_INDEX_1 <CONFIG_BAND_GROUP_INDEX_1>` Kconfig options, respectively.
