    Ethernet LANs. The following paragraphs elaborate on the network function of the wireless access point. DWL-900AP Bridging The Wireless Access Point functions as an intelligent bridge. It listens to all data traffic on all its interfaces and maintains a MAC address database in much the same way that an Ethernet switch maintains a MAC address table.
  • Page 17 Network Functions of the Access Point (continued) DHCP Support The access point supports the Dynamic Host Configuration Protocol (DHCP) used to obtain a leased IP address and network configuration information from a remote server. When DHCP is enabled, the access point sends out a DHCP request to obtain the IP settings and network configuration information.
  • Page 18 Network Functions of the Access Point (continued) Data Transfer Rates The actual rate at which data transmission occurs varies according to the strength of the signal transmitting the data. Distance and environment can effect the strength of the signal that can be transmitted and received. The signal strength determines the type of modulation technique used to encode data, which effects the volume of data (i.e.
