A bitfield describing the specifc access modes and technologies supported by a device and the access technology in-use when connected to a mobile network. Unknown or invalid mode. For certain operations, allow the modem to pick any available mode. GPRS EDGE UMTS (3G) HSDPA (3G) Prefer 2G (GPRS or EDGE) Prefer 3G (UMTS/HSDPA/HSUPA/HSPA) Use only 2G (GPRS or EDGE) Use only 3G (UMTS/HSDPA/HSUPA/HSPA) HSUPA (3G) HSPA (3G) GSM GSM Compact A bitfield describing the specific radio bands supported by the device and the radio bands the device is allowed to use when connecting to a mobile network. Unknown or invalid band For certain operations, allow the modem to select a band automatically.
