You can throttle their upload speed as it passes through your traffic
shaper, but not as they send traffic onto your wireless network.

Cust <-> CustRadio <-> BaseRadio <-> Shaper <-> Internet

If the customer saturates the wireless link between the radios with
traffic, you can't do anything about that at the shaper. But you can
control how fast traffic to or from the customer leaves the shaper in
either direction.

If you're trying to prevent saturation of the wireless link, you need
a traffic shaper at each end of it to control traffic across the
wireless shot. If you're just trying to keep track of customers
bandwidth and not worried about your wireless shot (maybe you've got a
full-duplex 100Mbps OFDM shot) then a single shaper would work.

Depends a lot on your wireless network. Full mesh, one to many, one to
one, etc...
