Wireless Connections
Install a PC Card in each computer that will be connected to the Internet or your local
network via radio signals.
Rotate both antennas on the back of the RoamAbout R1 to the desired position. For more
effective coverage, position one antenna along the vertical axis and the other along the
horizontal axis. Place the RoamAbout R1 in a position that is located in the center of
your
wireless network. Normally, the higher you place the antenna,
the better the performance.
Computers equipped with PC Cards can communicate with each other as an independent
wireless LAN by configuring each computer to the same radio channel. However, the
RoamAbout R1 can provide access to your wired/wireless LAN, or to the Internet, for all
wireless workstations. Each wireless PC in this network infrastructure can talk to any
computer in the wireless group via a radio link, or access other computers or network
resources in the wired LAN infrastructure or over the Internet via the RoamAbout R1.
The wireless infrastructure configuration not only extends the accessibility of wireless PCs
to the wired LAN, but also doubles the effective wireless transmission range for wireless
PCs by retransmitting incoming radio signals through the RoamAbout R1.
A wireless infrastructure can be used for access to a central database, or for connection
between mobile workers, as shown in Figure 1-2.
