Removing lower HT MCS values ENCOURAGES ROAMING?

Hi,

I`ve never removed the lower HT MCS values but I am considering removing MCS 0,1 and 2 for HT and corresponding additional spatial stream values (8,9,10 and 16,17,18) to encourage devices to roam to a more powerful AP rather than hang on to a lower powered AP. It may also aid in disconnecting the problematic clients still hanging on but a significant distance away.

Q: Does removing lower HT MCS Values encourage roaming?

Q: Should this approach replace/be in addition to our current technique of using signal ranges in access-list.

/caps-man access-list
add action=accept interface=all signal-range=-79..120
add action=reject interface=all signal-range=-120..-80

My initial thoughts are that its one or the other as they are linked in that dBm values relate to HT MCS values as per table below:

But then I am only one mind not many and perhaps one is better than the other?

If anyone has any thoughts / experiences that they could share we would be grateful and feedback our experience if we do implement it.

Kind Regards

Aidan
