2.5. Deploying the WLAN Hotspot Access Gateway
After the settings have been configured, deploy the gateway to the field application environment. You
have to connect AP(s), modem(s), and RADIUS server(s) to the gateway. The system configuration in
Fig. 16 illustrates how to deploy the WLAN hotspot access gateway.
NOTE: The wireless model of WLAN hotspot access gateway has a built-in access point. If the RF
coverage of the built-in access point is enough for your venue, no additional stand-alone access point
is necessary.
In this configuration, one DSL/cable modem is connected to the WAN port (as WAN 1) of the gate-
way and another modem is connected to the LAN 1 port (as WAN 2) of the gateway. Two APs are
connected to the LAN 2 port and LAN 3 port, respectively. Finally, a RADIUS server is connected to
the LAN 4 port of the gateway. The gateway works together with the RADIUS server to decide
whether a wireless client (the notebook computer or the PDA) is allowed to access the Internet
through the broadband modems.
NOTE: Although the RADIUS server in this sample configuration is on the “LAN” side, in a real ap-
plication, it can be on the “WAN” side, that is, on the Internet.

2.6. Setting up Client Computers
Before a wireless user can access the Internet through the gateway, the wireless and TCP/IP settings
of his/her computer or PDA must be configured adequately to match those of the gateway. In addition,
if Web redirection or IEEE 802.1x EAP-MD5 authentication methods are used,
user name and pass-
word information must be set up on the RADIUS server. On the other hand, if IEEE 802.1x EAP-TLS
authentication method is used, a digital certificate must be installed on the computer or PDA and on
the back end RADIUS server.
