There are two options:
Client: The Galaxy router will act a client function to send data to the
specified DSC.
Server: The Galaxy router will act a server to listen the data transfer
from the specified DSC.
Protocol
There are TCP and UDP options for selection. Based on past experience,
GPRS/EDGE or CDMA 1x channel is not reliable due to radio propagation. UDP is
recommended for transmitting real time information with data checksum, such
as SCADA system. TCP protocol may be better for transmitting files.
