Usage guidelines
IMPORTANT:
This command is supported only by Sierra MC7354 (ATT version) and MC7304 4G modules.
Multiple frequency bands are available for accessing the GSM network. When the network
environment changes, the 3G/4G modem might change the working band automatically to adapt to
the change. To avoid link instability caused by frequency changes, you can specify a GSM frequency
band for the 3G/4G modem.
Examples
# Specify the GSM 1800 MHz band for the 3G/4G modem.
<Sysname> system-view
[Sysname] controller cellular 0/0
