The 3Com AirConnect 11 Mbps
Wireless LAN Solution enables you to
overcome many of the limitations
imposed by traditional wired networks.
You can count on it to:
■
Provide network access in hardto-wire locations such as older
buildings, solid-wall structures,
and clean rooms.
■
Ensure hassle-free connectivity
in spaces that are frequently
reconfigured.
Based on the IEEE 802.11 High
Rate standard (802.11b), the 3Com
AirConnect Wireless LAN Solution
enables you to send and receive information at speeds of up to 11 Mbps—
over five times faster than previous wireless LANs. Each Access Point supports
up to 63 simultaneous users and provides 300 feet (91 m) of wireless
coverage in a standard office environment. With 3Com’s mobility features
and PowerBASE-T-powered Access
Points, you can deploy wireless networking across your entire company,
allowing users to roam at will.
Fast, Reliable Performance
for Your Mobile Users
With the 3Com AirConnect 11 Mbps
Wireless LAN Solution, mobile users
are guaranteed fast, reliable performance. Each Access Point supports
dynamic rate shifting, which automatically adjusts the connection speed to
compensate for radio-frequency interference. Automatic load balancing
distributes wireless traffic across multiple Access Points to optimize network
performance. And support for DHCP
and Extended Roaming means users
moving across the company can experience seamless connectivity without
having to reconfigure their
network settings.
Simple Installation,
Configuration, and
Management
Unlike other vendors, 3Com provides
unique installation management and
mobility tools, making this wireless
LAN Solution as easy to install and
configure as it is to use. AirConnect
wireless LAN Access Points connect to
your “wired” network using standard
10BASE-T connections, while the supplied PowerBASE-T module eliminates
the need to run AC power to them. The
module converts AC main power to
low-voltage DC that can be supplied to
the Access Point over an unused pair in
the same Category 5 cable that carries
the data. This single feature can help
you realize significant savings in
setup costs alone.
The 3Com AirConnect Wireless
LAN Solution also includes a Site
Survey Utility, which uses signal
strength and packet error information
to help you determine where to place
your Access Points for best coverage.
Once installed, 3Com AirConnect
offers several management tools and
options. Support for the IEFT industrystandard Simple Network Management
Protocol (SNMP) means you can
leverage existing network management
platforms to monitor and manage a
wide variety of networking and radio
variables. Web-based management lets
you manage Access Points from anywhere on the network, using a standard
Web browser. And Transcend
®
Network
Control Services management software
gives you comprehensive administration, monitoring, and troubleshooting
for both your wireless and wired
3Com network.
Enhanced Security
3Com AirConnect Wireless LAN
Access Points offer multiple layers of
security, including spread spectrum
signaling, access control lists, domain
identification, and authentication. End
stations need to have their Access Point’s
ID before they can be connected, while
Access Points can use access control
lists of individual MAC addresses to
prevent unauthorized devices from
connecting. Wired Equivalent Privacy
(WEP)-compliant data encryption,
using either 40- or 128-bit encryption
keys, is also available to protect all
wireless data transmissions.
Wi-Fi™Certified for
Compatibility
The 3Com AirConnect Wireless LAN
solution is fully IEEE 802.11b-compliant at 1, 2, 5.5, and 11 Mbps and
is backwards compatible with other
Direct Spread Spectrum products that
support the original IEEE 802.11 wireless standard for 1 and 2 Mbps. 3Com
AirConnect products constitute part
of the Wi-Fi
™
test bed and are Wi-Ficompliant, ensuring standards-based,
cross-vendor interoperability with other
Wi-Fi certified products.

3Com®AirConnect®11 Mbps Wireless LAN Solution Features and Benefits
Features Benefits
Reliable Performance Without Wires
Load balancing PC Cards and PCI cards automatically switch to the best available Access Point when the
current Access Point becomes congested or the signal weakens. This ensures uninterrupted access to network services and optimum data rates.
Dynamic rate shifting Access Points dynamically support 11, 5.5, 2, and 1 Mbps for maximum availability and
reliability of network connections. The proper data rate is determined automatically,
based on signal strength.
Antenna diversity All 3Com AirConnect products feature antennae with signal diversity. Each product has
two antennae to improve the likelihood of strong signal reception.
Separate, movable antenna PCI cards feature a separate antenna that can be placed on a wall, desktop, or bookcase
for desktop computers (PCI Card) to allow the best reception, regardless of the computer’s location.
Ease of Installation
PowerBASE-T Reduces installation cost and effort by eliminating the need to run separate AC circuits—
the PowerBASE-T module supplies each Access Point with low-voltage DC power over
the 10BASE-T connection.
Site survey utility Helps IT managers determine the best placement for each Access Point by logging the
signal strength from different locations in the building.
Extended Roaming PC Cards let users travel between Access Points as well as roam throughout the company
without losing their network connection.
DHCP support The Dynamic Host Configuration Protocol (DHCP) automatically obtains leased IP
addresses from a DHCP server. This allows notebook users to roam seamlessly, automatically obtaining new IP addresses as they suspend and resume operations.
DynamicAccess
®
mobile Helps IT administrators create and distribute location-specific configuration profiles for
connection manager various LAN, modem, and wireless communications. One-click access to a menu of
preset profiles reduces help desk calls from users as they change locations or
connection types.
Power-saving modes Access Points can buffer packets, allowing PC Cards to reduce their power consumption
by entering a sleep mode when out of range and resume full connectivity when they
sense a new Access Point.
Manageability
SNMP support 3Com AirConnect provides support for monitoring a wide array of network and wireless
parameters using your existing network management platforms.
Embedded HTTP server Each Access Point contains an integrated Web server that allows administrators to
access and set configuration parameters, monitor performance, and run diagnostics
from any Web browser—anywhere on the network.
Bulk configuration For even greater ease of administration, the configuration of any Access Point can be
automatically propagated to other Access Points on the same subnet.
Remote configuration and Administrators can use HTTP, Telnet, Serial, PPP, or SNMP to remotely configure or
firmware upgrade upgrade Access Points. A firmware upgrade utility allows you to easily upgrade PC Cards
and PCI adapters with the latest features, easing IT burdens and lowering the total cost
of ownership.
Security
Access control This utility ensures that only 3Com AirConnect devices programmed with the WLAN ser-
vice area ID of a given 3Com AirConnect Access Point can connect to that Access Point.
For greater security, you can create an access control list specifying the MAC addresses
of the wireless devices that are allowed to associate with a particular 3Com AirConnect
Access Point.
Encryption* Wireless clients have the option of using 40- or 128-bit encryption* keys and the RC4
algorithm to encrypt the wireless portion of data transmissions. AirConnect Access
Points also offer the Wired Equivalent Privacy (WEP) defined in the 802.11b standard.
Standards-based
IEEE802.11b- AirConnect products comply with IEEE802.11b at 1, 2, 5.5, and 11 Mbps. They offer
and Wi-Fi
™
-compliant backwards compatibility with the original 802.11 standard at 1 and 2 Mbps,
interoperating with other Direct Spread Spectrum products. The AirConnect Wireless
LAN solution is also Wi-Fi
™
certified, and is part of the Wi-Fi test bed, ensuring
cross-vendor interoperability.
