[. . . ] Core Units Controlling Entire Wireless Network The DWS-3024/3024L/3026 switches are the core units that consolidate the security, manage the bandwidth and maintain the intelligence of an entire wireless network. In addition to monitoring users' identities and maintaining their authentication as they roam, these switches can configure and control all aspects of the wireless access points, including their RF channel/power management, wireless traffic segmentation, AP roaming/AP load balancing, rouge AP detection, and AP access security. Designed for Easy Deployment of High-Performance Wireless LAN Designed for distributed deployments in the wiring closet, each switch can support up to 24 or 48 wireless access points. [. . . ] This automatic adjustment can be programmed to take effect at a certain time or time intervals, minimizing the need for network administrators to manually intervene.

To make up for a sudden RF signal vacuum created by any "dead" AP (AP with DC power failure, for example), the switch automatically increases the transmitter output power of all neighboring APs to expand their RF coverage, thereby "healing" the network "wound. " To ensure continuous connection for current clients, the switch performs load balancing across access points when network traffic reaches a certain threshold, while rejecting new client-to-AP associations to avoid bandwidth overcrowding. Simplified Configuration & Deployment Through a centralized management platform, network maintenance and configuration become a more efficient process. By running an Internet browser on any PC connected to the network and typing in an IP address of a managing switch, administrators can view the topology map and pinpoint the locations of the AP and the switch itself. The map uses AP icons on which administrators can click to select, and shows colors to differentiate the different RF channels used by the AP. For quick replacement of a failed AP, administrators can easily locate the AP on the map, swap it with a new one, and apply the same configuration profile to the new unit. Maximized Wireless Connection Through centralized RF policies, auto-selection of the least utilized channels and AP load balancing, the DWS-3024/3024L/3026 can effectively manage the wireless bandwidth to optimize WLAN traffic. The switch maintains a centralized database of wireless user's access information such as their MAC addresses and authentication keys. On a network site deployed with multiple peer switches, this information is also swapped among the switches themselves. As wireless users roam around the office using wireless equipment, they may change their connection from AP to AP. By constantly monitoring the APs status, the switch can establish an APto-AP roaming for these users without requiring them to re-establishing authentication keys. This fast roaming process results with disruption-free, reliable wireless connectivity crucial for mobile applications such as Wi-Fi IP phone and wireless PDA connection. Adaptable Wireless Most of the current wireless LAN controllers' architecture requires wireless traffic to return to the controller for centralized processing, causing unnecessary traffic delay. The DWS-3024/3024L/3026 switches offer administrators additional options. Depending on the wireless application, wireless traffic can either be tunneled back to the switch for better security control, or locally forwarded at the access point for optimal performance. This device offers administrators maximized flexibility with options to tunnel guest traffic to the switch for centralized security control, and forward VoIP traffic directly from the access point for optimal performance. Maximized Network Security Each client connecting to the wireless network goes through a strict authentication process to ensure maximum security.
