5/26/05 Cisco 1000 Series Lightweight Access Point External and Internal Antennas

OL-7426-03

When equipped with an optional factory-supplied external antenna, the 802.11a Cisco Radio supports

receive and transmit diversity between the internal antennas and the external antenna. The diversity

function provided by Cisco Radios can result in lower multipath fading, fewer packet retransmissions,

and higher client throughput.
