1031484-0001 Revision 2
These units, in combination with an antenna, provide satellite
connectivity for multiple local area network (LAN) hosts through
one DIRECWAY System. All the necessary software resides on
the Gateway, which serves as the router. Because the software is
on the Gateway, there is no need for a computer to run client
software, unlike previous versions of DIRECWAY.
Figure 1 illustrates the functionality of the DW4020 within a
DIRECWAY network. Note that the DW4020 is independent of
operating platforms. It can also be used with devices other than
computers, such as point-of-sale (POS) terminals or credit
verification devices.
