Wireless LAN
Wireless communication occurs over radio waves rather than a wire. Like a cordless
telephone, a WLAN uses radio signals instead of wires to exchange data. A wireless
network eliminates the need for expensive and intrusive wiring to connect computers
throughout the home or office. Mobile users can remain connected to the network even
when carrying their laptop to different locations in the home or office.
Each computer or other device on a WLAN must be Wi-Fi enabled with either a built-in or
external wireless adapter.
Laptops —Use a built-in wireless notebook adapter, a wireless PCMCIA slot adapter, or
a wireless USB adapter.
Desktops —Use a wireless PCI adapter, wireless USB adapter, or compatible product in
the PCI slot or USB port, respectively.

Sample Wireless Network Connections (CH6643E model shown)
Your maximum wireless operation distance depends on the type of materials through
which the signal must pass and the location of your CH6643E and clients (stations). CBN
cannot guarantee wireless operation for all supported distances in all environments.
Note: To get better wireless coverage, please put your CH6643E
wireless gateway vertically.
Wired Ethernet LAN
You can easily connect any PC with an Ethernet cable to the CH6643E Ethernet port.
Because the CH6643E Ethernet port supports auto-MDIX, you can use a straight-
through or cross-over cable to connect a hub, switch, or computer. Use category 5, or
better, cabling for all Ethernet connections.

4
Sample Ethernet to Computer Connection (CH6643E model shown)
A wired Ethernet LAN with more than four computers requires one or more hubs,
switches, or routers. You can:
Connect a hub or switch to any Ethernet port on the CH6643E.
Use Ethernet hubs, switches, or routers to connect up to any combination of 253
computers and wireless clients to the CH6643E.
More detailed information on Ethernet cabling is beyond the scope of this document.
