The DWS-3160 is D-Link's latest Unified L2+ Gigabit Wireless Switch. Designed to be the ideal mobility solution for medium-sized and large enterprises and service providers, the DWS-3160 empowers administrators to exercise total control over their wireless networks by centralizing all aspects of provisioning and management. Able to manage up to 48 D-Link Unified Access Points by itself and up to 192 in a Peer Group, the DWS-3160 can be configured to act either as a Wireless Controller in the core network, and as an L2+ Gigabit Switch at the edge, enabling it to be seamlessly integrated into any existing network infrastructure. The DWS-3160 comes in two models, with or without PoE support.
The DWS-3160 is able to centralize all critical WLAN management functions, thereby eliminating the need to manage access points individually. The administrator simply assigns a profile to an individual D-Link Unified Access Point, and the configuration corresponding to that profile would be applied onto that access point automatically. In addition, the DWS-3160 can apply new firmware to all D-Link Unified Access Points on the network, thus greatly simplifying the upgrade process. The DWS-3160 also excels as an advanced L2+ switch. Complete with RIPv1/v2 dynamic routing, ACL security, multi-layer QoS, comprehensive VLAN support, as well as Multicast Snooping capabilities, the DWS-3160 enables easy and flexible deployment. Furthermore, multiple DWS-3160s can form a Peer Group, which enables the administrator to configure all switches from one Peer Group Master. As the size of the Peer Group grows, so can the number of managed D-Link Unified Access Points. Up to 192 D-Link Unified Access Points may be managed by a Peer Group. This helps to significantly simplify management and reduce maintenance efforts when a network is scaled up.
The DWS-3160 offers a state-of-the-art Wireless Intrusion Detection System (WIDS), which empowers administrators to detect Rogue Access Points and Rogue Clients, effectively preventing them from causing damage to the network. The administrator can also activate various threat detections and use Radio Frequency Scan to sweep the entire wireless network to identify any possible security breach in advance. When working in conjunction with D-Link Unified Access Points, Virtual Access Points may be easily configured and managed, allowing the administrator to assign different access privileges to different classes of users. In addition to WPA and WPA2, an added measure of protection is added with an advanced captive portal, thus enabling only authorized users to utilize the wireless network. On the wired side, the DWS-3160 utilizes Access Control Lists to tightly control what goes in and out of the network by setting up a number of simple rules. Along with other advanced security features, such as 802.1X Network Access Control and advanced Denial-of-Service Protection, the DWS-3160 provides robust and centralized security, ensuring maximum network reliability.
When a number of access points are deployed close to each other, such as in a school or university setting, interference may result if proper RF management isnÕt implemented. The DWS-3160 monitors the radio spectrum utilization in the network, and will automatically assign the most optimized channel to each access point under its management. This greatly reduces RF interference and allows the administrator to deploy APs more densely. To further minimize interference, the DWS-3160 can also adjust the transmit power of each radio independently. When a nearby AP is operating on the same channel, the DWS-3160 will automatically lower its transmission power to minimize interference. At any time should the nearby AP drop from the network, the DWS-3160 will instruct the neighboring access point to increase its transmission power to expand coverage. To ensure that no access point is overburdened while others sit idle, the DWS-3160 can prevent D-Link Unified Access Points from accepting new association requests if its resources are fully utilized. A neighboring Unified Access Point will instead pick up the load. This ensures that proper load balancing is in place, and the network will function in the most optimal state.
Wireless clients can enjoy seamless and uninterrupted roaming from AP to AP if they are managed by the same DWS-3160, even if they are not in the same subnet. Because the DWS-3160 employs various mechanisms such as pre-authentication and keycaching, wireless users can freely roam the entire network without needing to re-authenticate. This allows mobile users to travel freely within any premise covered by the DWS-3160Õs managed APs without having to worry about network connectivity, thus enabling for a truly mobile workplace.
