Packet/Asynchronous Data Overview

The GSP-1620 modem handles both packet and asynchronous data connections. For a particular SCADA application, one may make more sense than the other. Table 5-1 compares the two types of data.

Tip QUALCOMM Globalstar packet data service has a lower overhead and faster connection time than asynchronous data does. In general, if a SCADA application does not specifically need asynchronous data, use packet data instead.

For more details about implementation issues specific to one type of data or the other, see Using Packet Data on page 5-21 and Using Asynchronous Data on page 5-30.
