High Performance and Wide Coverage
For simple, reliable, high-speed 802.11g
wireless connections choose a winning trio:
the 3Com®OfficeConnect®Wireless 11g
Access Point, 3Com OfficeConnect Wireless
11g PC Card, and 3Com OfficeConnect
Wireless 11g USB Adapter. With these
products, users can roam about the office—
accessing network resources and the
Internet at speeds up to 54 Mbps—ideal
for high-bandwidth applications.
Performance-boosting features such as
packet bursting, compression, and concate-
nation increase the effective transmission
speed with no user intervention.
Compatible
Your existing wireless network investment
is preserved because the 3Com
OfficeConnect Wireless 11g Access Point
supports 802.11b as well as 802.11g wire-
less devices. Wi-Fi certification helps
ensure interoperability with certified prod-
ucts from other vendors.
Economical
Wireless networks can be a viable alterna-
tive 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.
Simple Installation and Use
Setup and operation are extraordinarily
easy, making these OfficeConnect products
an intelligent choice for first-time wireless
users and small offices; 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 Wireless Card Manager
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 for
instant connection.
Convenient
For added flexibility, PRISM Nitro
Directlink enables wireless users to estab-
lish direct, secure high-speed links while
still maintaining communications with an
access point.
Secure
To protect wireless connections, these
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
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.
