Claim 15:
16. An apparatus for receiving a packet on a wireless network, wherein the packet includes a preamble field where a preamble is located, wherein the preamble is made up of a plurality of identical patterns, the apparatus comprising:
a first antenna to receive a first signal containing the packet;
a second antenna to receive a second signal containing the packet;
an antenna switch to select the first signal or the second signal from the first antenna and the second antenna by toggling the antenna switch during an idle time;
an RF circuit to process the first signal and the second signal and create a first set of one or more received fragments when processing the first signal and create a second set of one or more received fragments when processing the second signal; and
a preamble detector to detect a preamble based on at least one pattern in either the first set or the second set, wherein each received fragment from the first set is at least one pattern in duration, and successive received fragments are spaced by the idle time equal to a duration of an integral number of identical patterns and each received fragment from the second set is at least one pattern in duration, and successive received fragments are spaced by the idle time equal to the duration of an integral number of identical patterns.
