Bandwidth Limitation

Currently the scenario implemented by me is as shown below:-

Take this for an example..
currently we have been working with this setup for p2p networks.

BTS Radio Config:-
Mode - station wds
bridge - wds-bridge1
wlan1 ip - 10.10.10.1/30
ether ip - 71.2.221.20/24
route gateway - 71.2.221.1

Client radio config:-
Mode - bridge
bridge - wds-bridge1
wlan1 ip - 10.10.10.2/30
ether ip - 71.2.221.21/24
route gateway - 71.2.221.1

Now wat i want to set is bandwidth limitation.
For instance I want to allow juz around 256kbps of bandwidth to client where do i need to do configurations and what all do i have to do?
Kindly let me know asap.Also mention me the radio on which I need to configure the settings.

If i need to add a queue let me know how wud it b and also dot down the parameters for the same.
Waiting for ur response.

Thanks
