1 INTRODUCTION
The 3Com® Wireless LAN Access Point 7250 supports 802.11g and 802.11b wireless users.
With their flexibility and unfettered access, wireless LANs are changing the way people work. Now with 3Com’s enterprise-class wireless access points, you can build a cost-effective, reliable, secure wireless network that provides users with seamless connectivity to the Internet, company intranet, and the wired corporate network from anywhere they happen to be—conference room, cafeteria or office.
Industry-leading security features and comprehensive management and performance features combine to make these enterprise class wireless access points an ideal choice for organizations ready to serve their increasingly mobile workforce.

PRODUCT FEATURES

The single wireless interface 802.11g 2.4 GHz, 54 Mbps access point creates an enterprise-class wireless LAN supporting up to 250 simultaneous users.

SECURITY

3Com offers one of the most robust suite of standards-based security on the market today.
To protect sensitive data broadcast over the wireless LAN, 3Com supports the Advanced Encryption Standard (AES). 3Com strengthens this basic security mechanism with additional security features, including:
MAC address access control listsIEEE 802.1x per-port user authentication with RADIUS server authentication
support
IEEE 802.1x supplicant support

SSH v2HTTP/HTTPSSNMP v3Temporal Key Integrity Protocol (TKIP)Legacy WEP 40/64 bit, 128 bit and 152 bitWireless Protected Access (WPA)Extensible Authentication Protocol (EAP) support: EAP-MD5, EAP-TLS,
EAP-TTLS, and PEAP

PERFORMANCE AND RELIABILITY

3Com wireless access point performance features ensure reliable and seamless connections for users wherever they roam:
Automatic channel selection automatically finds the least loaded channel for
interference-free communication.
Auto network connect and dynamic rate shifting keep users connected
through a wide variety of conditions by changing to the optimum connection speed as they move through the network.
Virtual Access Point (VAP) support provides flexibility by allowing a single
access point radio to operate as two separate access points.
Wireless Distribution System (WDS) Bridging support allows you to create
large wireless networks in areas where pulling wires is restricted or cost-prohibitive by linking several wireless access points together with WDS links.
Virtual Access Point (VAP) Support
Virtual Access Point (VAP) support allows an access point radio to operate as two separate access points, providing multiple wireless services to clients in a network. Each VAP can be configured to provide access to different network resources and can support different levels of security.
For example, in a university network, an AP could be used to offer two services: The first service provides access to protected data for authenticated university staff members, while the second service provides open access to the Internet for unauthenticated users, such as students or visitors.
Two VAPs per radio are available, and each VAP can be configured with its own security settings.
For information on setting up and configuring VAPs, see “Enabling Virtual Access Point (VAP)” on page 50.

WDS Bridging and Spanning Tree Protocol (STP) Support
A Distribution System (DS) is a network (typically a wired network) that interconnects separate access points into a single LAN. With WDS, the interconnection no longer needs to be physically wired. WDS medium to interconnect separate access points, thereby eliminating the cost and inconvenience that may hinder wire installations.
A WDS link can be used in a simple point-to-point link, a complex point-to-multipoint link, or a multilayer topology.

Additionally, Spanning Tree Protocol (STP) support prevents loops from being formed on the network. For more information on these items, see the Wireless LAN Access Points User Guide.
For WDS and STP configuration instructions, see “WDS/STP Settings” on page 45.

MANAGEABILITY

3Com offers a wide range of standards-based management support, from SNMP to 3Com Network Supervisor and HP OpenView for seamless integration with your wired network.
Wireless Infrastructure Device Manager and Wireless LAN Device Discovery tools let you configure parameters, run diagnostics, backup and restore configurations, and monitor performance from anywhere on the network using an embedded web server browser. You can also update wireless device software on multiple devices using 3Com Network Supervisor to simplify bulk updates.
With Power over Ethernet (PoE) support, the same Category 5 cable that connects your access point to the data network also provides its power. A single cable installation dramatically improves your choice of mounting configurations because you no longer need to consider AC power outlet locations. PoE support makes it easier than ever to overcome installation problems with difficult-to-wire or hard-to-reach locations.

802.11G WIRELESS NETWORK STANDARD

802.11g operates in the 2.4 GHz band at up to 54Mbps, and supports the widest coverage—up to 100 meters (328 feet). However, is subject to a greater risk of radio interference because it operates in the more popular 2.4 GHz band.
Consider 802.11g when you need wider coverage and vendor compatibility and you are:
Maintaining support for existing 802.11b users and the existing wireless
investment while providing for expansion into 802.11g.
Implementing a complete wireless LAN solution, including bridges, gateways,
access points and clients; Wi-Fi certification guarantees compatibility among

STANDARD NETWORK CONFIGURATION AND PLANNING

The wireless solution supports a stand-alone wireless network configuration as well as an integrated configuration with 10/100
The wireless network cards, adapters, and access point can be configured as:
Ad hoc for departmental or SOHO LANInfrastructure for wireless LANInfrastructure wireless LAN for roaming wireless PCs
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.

INFRASTRUCTURE WIRELESS LAN

The access point can also provide access to a wired LAN for wireless workstations. An integrated wired/wireless LAN is called an infrastructure configuration. A Basic Service Set (BSS) consists of a group of wireless PC users, and an access point that is directly connected to the wired LAN. Each wireless PC in this BSS can talk to any computer in its wireless group via a radio link, or access other computers or network resources in the wired LAN infrastructure via the access point.
The infrastructure configuration not only extends the accessibility of wireless PCs to the wired LAN, but also increases the effective wireless transmission range for wireless PCs by passing their signal through one or more access points.

INFRASTRUCTURE WIRELESS LAN FOR ROAMING WIRELESS PCS

The Basic Service Set (BSS) is the communications domain for each access point. For wireless PCs that do not need to support roaming, set the domain identifier (SSID) for the wireless card to the SSID of the access point to which you want
connect. A wireless infrastructure can also support roaming for mobile
to workers. More than one access point can be configured to create an Extended Service Set (ESS). By placing the access points so that a continuous coverage area is created, wireless users within this ESS can roam freely.

ADVANCED NETWORK CONFIGURATION AND PLANNING

Virtual Access Point (VAP) and WDS Bridging capabilities allow the access point to be integrated into many new network configurations. Some common configurations are explained briefly in this section:

Public/private access point serviceRemote building wireless access with the AP8250 and 802.11a Bridging KitRemote building wireless access with the AP8250 and 802.11g Upgrade Kit

PUBLIC/PRIVATE ACCESS POINT SERVICE
The public/private access point service configuration allows the access point to provide public Internet access while simultaneously providing secure access to the enterprise network.
In this configuration, an AP7250 access point is configured with two Virtual Access Points:
The first Virtual Access Point is configured to support one SSID that is
broadcast with no security.
The second Virtual Access Point is configured with a different, private SSID
that is not broadcast. The private SSID should be assigned to a separate VLAN and use 802.1x
authentication with either TKIP or AES encryption to a RADIUS server.

be
Whether you choose to mount the access point on a wall or place it on a flat surface, make sure to select a clean, dry location that is elevated enough to provide good reception and network coverage. Do not mount the access point on any type of metal surface. Do not install the access point in wet or dusty areas. The site should not be close to transformers, heavy-duty motors, fluorescent lights, microwave ovens, refrigerators or any other electrical equipment that can interfere with radio signals.
If you are connecting the access point to a wired network, the location must provide an Ethernet connection. You will need to run an Ethernet cable from the power supply to the access point.
An access point provides coverage at distances of up to 100 Meters (300 Feet). Signal loss can occur if metal, concrete, brick, walls, floors or other architectural barriers block transmission. If your location includes these kinds of obstructions, you may need to add additional access points to improve coverage
13
Configuring a wireless LAN can be as easy as placing a 3Com Wireless Access Point in a central area and making the necessary connections to the AP and the clients. However, installing multiple Access Points may require more planning. Using the 3Com Site Survey tool (located on the installation CD) can help you determine if your wireless LAN connectivity and throughput is adequate and all users are covered by an Access Point.
If you plan to use an optional antenna instead of the standard detachable antennas that are supplied, review Antenna Model” on page 21 before selecting the final location and be sure to allow for routing the antenna cable as required.
For optimal performance, ensure the access point operates in temperature ranges between –10° C to 40° C (14° F to 104° F).
Caution: Regulatory restrictions dictate that when this device is operational, the minimal body-to-antenna distance is 1 Meter (3 Feet).
