Complete, Simultaneous Standards

Support

Now even small to mid-size offices can

enjoy the freedom of universal high-speed

networking—without wires. The 3Com

OfficeConnect

Wireless 11a/b/g Access

Point and PC Card support all three 802.11

wireless networking standards to preserve

existing investments while accomodating

the latest technologies. Wi-Fi certification

helps ensure interoperability with certified

products from other vendors.

Security Protection

To protect wireless connections, both

products support 256-bit WPA encryption

for high-level security and 40/64-bit and

128-bit WEP encryption for legacy clients.

The access point’s SSID Broadcast Disable

and MAC control lists features prevent

unauthorized clients from connecting to

the wireless network.

Reliable Performance

Depending on the wireless standard used,

mobile users can access network resources

and the Internet at speeds up to 108 Mbps

for 11a and 11g users. Super AG packet

bursting, compression, fast frames, and

dynamic turbo features automatically boost

performance with no user intervention.

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

select the least busy channel.

Simple Installation & Use

An intelligent choice for first-time wireless

users in smaller-office environments, the

access point and PC Card install quickly and

easily; typically no manual configuration is

required. To speed setup, administrators can

copy a single configuration to other access

points on the network. The PC Card’s

Wireless Card Manager also lets administra-

tors create profiles for notebook users that

reflect specific settings for each place they

travel: users select the proper profile for

instant connection.

Convenient

Wireless Distribution System (WDS)

support allows organizations to create a

completely wireless LAN in areas where

wired networks are not feasible.

WLAN Standards at

a Glance

Understanding the characteristics of the 802.11 standards can help you make the

best choice for your wireless implementation plans.

STANDARD SPEED RANGE FREQUENCY APPLICATION CHARACTERISTICS

802.11a 54 Mbps 50 meters 5 GHz Supports a denser user base because more non-overlapping

108 Mbps in (164 feet) channels allow more access points in a tighter space. High

Turbo mode speeds easily handle high-bandwidth applications, but

within a more limited coverage area.

802.11b 11 Mbps 100 meters 2.4 GHz Most widely deployed wireless standard, with a high

(328 feet) degree of multivendor interoperability. Operates in the

relatively crowded 2.4 GHz spectrum. Supports a slower

speed within a wider coverage area.

802.11g 54 Mbps 100 meters 2.4 GHz High speeds easily handle high-bandwidth applications

108 Mbps in (328 feet) such as voice, video, or multimedia. Supports a large

Turbo mode existing customer base because it is backward compatible

with 11b products. Wide coverage area makes it a good

choice for public hot spots. Faces the same spectrum

issues as 11b.

Description

RELIABLE HIGH PERFORMANCE

High speed Supports speeds up to 108 Mbps in Turbo mode for 11a and 11g clients.

Dynamic packet bursting Increases throughput by sending more frames per given time period; benefits both 11b and 11g clients.

Real-time hardware compression Increases throughput by compressing data frames for 11b and 11g clients, does not affect the host processor.

Fast frames Extends the frame size to transmit more data per frame, boosting efficiency with less overhead for

11g and 11b clients.

Dynamic/static turbo mode Activates and doubles the effective 11a and 11g transmission rate by combining two channels; dynamic

mode automatically adjusts bandwidth use for need and environment.

User support Access point supports up to 128 simultaneous wireless users, allowing plenty of room for growth.

Clear Channel Select (Access Point) Chooses the channel with the least traffic for clear, quick connections.

Dynamic rate shifting Automatically matches the best connection speed in response to changing traffic and environmental conditions.

EASY TO USE

3Com Access Point Discovery program Automatically identifies and configures network devices with little to no manual configuration required.

Access Point save and restore Copies settings to wireless devices on the network, simplifying and speeding LAN setup.

3Com Wireless Card Manager (PC Card) Creates profiles for each place wireless notebook userstravel, displays connection status, and features

simple-to-use diagnostic tools.

Web-based administration (Access Point) Familiar browser interface lets administrators configure and manage network devices from anywhere.

CONVENIENT

Wireless Distribution System support (Access Point) Enables users to create large wireless networks or a wireless LAN in large, open areas where pulling wires is

cost prohibitive, restricted, or physically impossible.
