DAP-3220 has a watertight housing, a built-in heater and a temperature sensor. It supports 802.3af Power over Ethernet (PoE), and can be placed at outdoor locations where power outlets are not easily accessible. Besides functioning as an AP, this device can also be configured to operate as a Wireless Distribution System (WDS) to act as a bridge for linking together networks in different buildings. It supports 64/128/152-bit WEP data encryption and WPA/WPA2 security functions. In addition, it provides MAC Address Filtering to control user access, and the Disable SSID Broadcast function to limit outsiders’ access to the internal network. DAP-3220 supports up to 8 SSID, allowing the administrators to logically divide the access point into several virtual access points all within a single hardware platform. Rather than having separate networks with several access points, administrators can deploy one single AP to support more than one application, such as public Internet access and internal network control to increase flexibility and keep costs down. The DAP-3220 supports 802.1Q VLAN Tagging, operating with multiple SSID to segment traffic to enhance performance and security. The DAP-3220 provides WLAN STA partitioning, a function useful for deployments such as hot spots. With station-to-station partitioning enabled, security is enhanced, since wireless users cannot peek at each other, and the possibility for data thievery is reduced.
