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.
