Enterprise-Class Wireless User Access Control and Management
3Com® Wireless Access Controllers provide wireless networks with expanded system capacity, enhanced performance and powerful control capabilities. Ideal for deployment in branch offices and campus networks where centralized management of wireline and wireless resources is critical, they provide redundancy, quality of service (QoS) in a roaming environment, and enhanced authentication and security features that surpass those of stand-alone wireless networks.
The 3Com Wireless Unified LAN Controller WX3008 has eight 10/100/1000BASE-T ports, four of which support PoE+. It ships with support for up to four managed access points and 1,024 wireless users— excellent for small-sized deployments and remote offices.
Expands Wireless Control over the Growing Enterprise
3Com wirelss controllers employ an innovative authentication mechanism based on user identities, rather than ports or devices, to guarantee network mobility and security. During authentication, an authentication server assigns a user profile to a device. If the user passes authentication, the device uses the configuration contents in the user profile to restrict the accessible resources of the user. When this user goes offline, the device disables the user profile. As a result, user profiles are applicable to online users rather than offline users. This includes users who did not pass authentication.
Information exchanged through access controllers in the WLAN network enables consistent access and security policies across the entire network. In addition, Advanced Encryption Standard (AES), Temporal Key Integrity Protocol (TKIP) and Wired Equivalency Protocol (WEP) encryption functions based on a combination of Wi-Fi® Protected Access (WPA™)/(WPA2™) and 802.1X authentication enhance network security.
Centralizes Management of 802.11n APs
3Com Wireless Controllers series can be used to manage 802.11a/b/g/n access points (APs). In 802.11n mode, the 3Com 802.11n-based AP can provide wireless access rates equivalent to six times the wireless access rates provided by a conventional 802.11a/b/g network, expanding coverage and capably deploying wireless multimedia applications.
The 3Com WX3000 Series also provides an embedded portal server to provide security authentication for users in places where clients cannot be installed.
Provides Fine Wireless User Management
Using MAC-based authentication and access control, the rights of user groups and specific users can be configured and modifed on the AAA server. This fine user rights control method greatly enhances the availability of the wireless network and enables network administrators to easily allocate access rights to various levels of users or user groups.
Enables Flexible Data Forwarding Modes
To ensure the seamless transmission of data, 3Com Wireless Controllers support both centralized and distributed data forwarding. Combining their mutual advantages, users can configure local forwarding for data traffic from clients with a specified service-set identifier (SSID), virtual LAN (VLAN), or SSID+VLAN and centralized forwarding for data traffic from other clients.
Supports Location-Based User Access Control
3Com Wireless Controllers supports AP-based user access control, enabling administrators to control the location a wireless user can access in the network. When a wireless user attempts to access the network, the authentication server forwards a list of APs that the user can access to the AC, ensuring that the wireless user can access only specified and pre-determined APs.
Applies Quality of Service Policies on a Per-User Basis
For networks based on user authorization, a user is authenticated before accessing a network. This authorization controls the network areas that a user can access as well as the network QoS (such as the access bandwidth and access priority) the user can obtain.
Controlled, Secure Access to Mission-Critical Data
To ensure users accessing a network comply with its security policies— minimizing the risk of security breaches or network downtime caused by poorly protected devices— 3Com Wireless Access Controllers provide an Endpoint Admission Defense (EAD) solution.
