all at speeds up to 54 Mbps at
distances up to 100 meters (328 feet).
These 11g products operate at almost
five times the speed of existing
802.11b devices, so they are ideal for
multimedia or other high-bandwidth
applications.
Setup and operation are extraordinarily easy, making these OfficeConnect
products an intelligent choice for
first-time wireless users and small
offices. Plug the access point into a
power source and it’s ready for use—
typically no manual configuration is
required. To speed setup for specific
configurations, a single access point
configuration can be copied to other
access points on the network. The PC
Card and USB adapter feature
Wireless Card Manager that lets an
administrator create profiles for
mobile users that reflect specific wireless LAN settings for each place they
travel: users just select the proper
profile and they are configured for
connection.
Compatible
Your existing wireless network investment is preserved because the 3Com
OfficeConnect Wireless 11g Access
Point supports 802.11b as well as
802.11g wireless devices. Wi-Fi certification helps ensure interoperability
with certified products from other
vendors.
Secure

products support up to 256-bit WPA
encryption for high-level security, and
40/64- and 128-bit WEP shared-key
encryption for legacy clients.
Reliable Connections
Economical
Wireless networks can be a viable
alternative to wired network expansions and an attractive solution for
home and branch offices, remote sites,
and classrooms. Since there’s no need
to drill holes or run Ethernet cabling,
it’s also cost-effective for temporary
networks. The access point supports
up to 128 simultaneous users, which
gives your organization plenty of
room to grow.
Dynamic rate shifting automatically
matches the best connection speed in
response to physical and traffic conditions so wireless connections stay
reliable. Clear Channel Select enables
the access point to scan the spectrum
and select the least busy channel.
