Summary: Range Extension The DWL-900AP+ Access Point connects the wireless LAN nodes (workstations, print servers, etc.) together via a 2.4GHz IEEE 802.11b wireless interface. It listens to all data traffic on its interface and maintains a MAC address database. MAC address information is updated dynamically. When necessary, the DWL-900AP+ uses the Address Resolution Protocol (ARP) to match IP addresses to MAC addresses and stores ARP information in its database as well.
