Three modes for base station selection are available:
1. Auto - This mode uses the default GSM base station selection mechanism. Use this default setting if you
don't have any preference.
2. Poll - This mode enables the device to switch to a different base station at the interval specified. The Base
Station Polling List is the list of base stations that can be used. In principle, this list is the base station
neighbor list reported by the GSM module. The neighbor list is listing all available base stations in the
descending order of their signal strength. Additional selection conditions are defined by the parameters
listed in the table below.

Description
This sets the maximum number of channels in the Polling Channel List.
This defines the duration in minutes when the next base station switching
occurs. Other than a single value, a range can also be specified using the
format min-max where min is the minimum interval and max is the
maximum interval. A random value in the range specified is then assigned
when a channel switching occurs which only occurs when the corresponding
channel is not in use.
This parameter defines how to form the Base Station Polling List.
When this is disabled, the Base Station Polling List is taken directly from the
neighbor list.
When this is set to Whitelist, only the base stations numbers listed can be
chosen from the neighbor list. Please note that the numbers appear in the
Whitelist may not appear in the neighbor list.
When this is set to Blacklist, the base station numbers in the Blacklist will
not be chosen from the neighbor list.
