Introduction

3Com's Wireless Solution supports a stand-alone wireless 
network configuration, as well as an integrated 
configuration with 10 Mbps Ethernet LANs.

The Wireless PCI card can be configured as:

• Ad hoc for departmental or SOHO LANs

• Infrastructure for enterprise LANs

Network Topologies

Ad hoc Wireless LAN

An ad hoc wireless LAN consists of a group of computers, 
each equipped with a wireless adapter, connected via radio 
signals as an independent wireless LAN.  Computers in a 
specific ad hoc wireless LAN must therefore be configured 
to the same radio channel. An ad hoc wireless LAN can be 
used for a branch office or SOHO operation.
