A method, apparatus, and article of manufacture for reducing broadcast traffic in a wireless backbone network. In operation, a wireless access point receives an address resolution protocol (ARP) message from a network device. The wireless access point determines the destination of the ARP message and attempts to identify the Ethernet address associated with the destination network device. If the Ethernet address cannot be determined, the access point sends an ARP request message to the other wireless access points on the network, requesting them to transmit ARP packets to the network device. When the desired network device comes within range of the network, the access points discontinue transmitting ARP packets and a message acknowledging the device's presence is transmitted to the original access point. This method of having access points periodically broadcast ARP packets to network devices reduces ARP broadcasting across the wireless backbone, thereby increasing network throughput.

A broadband bicone antenna system supports improved VSWR operation of a high-impedance bicone antenna having a reduced aperture size, high input impedance at the central vertex of the cones, one or more pattern tuning filters associated with the cones, and input filtering for frequency selective impedance matching. Pattern tuning filters can improve the radiation pattern at different frequencies by controlling the electrical length of the antenna in response to the frequency components of the associated wideband signal. Impedance matching input filters can improve the signal matching to couple radio frequency energy into the antenna system from a feed line. Mutual tuning of the pattern tuning filters; the impedance matching input filters; and the impedance of the bicone antenna itself can improve the overall voltage standing wave ratio (VSWR) performance of the bicone antenna system over a broad range of operating frequencies.
