Not necessarily.  You're thinking of a repeater being used by continuous
streams, but in a packet switched network, the packets from different
devices would arrive at the repeater at slightly different times (just as
they do for an a/p), and the device would be shared.

The a/p's main disadvantage is that every packet going through it needs to
be retransmitted AT A LATER TIME, which will reduce the channel capacity.  A
traditional repeater retransmits SIMULTANEOUSLY, which can save time and add
bandwidth in some cases.  Also, the repeater means that there are no hidden
nodes, as all nodes participating are retransmitted by the repeater and
appear on its output frequency.

(of course, this is a bit of a hypothetical discussion, as the wireless gear
is designed to transmit/receive on the same band of frequencies, not
offset).
