W80B dm-base role

[Lansalot]

Hi
I would like to check please, I see reference in the changelog that the DM-Base role is no longer an option after fw 83.30.

If I am right in my understanding - before 83.30 you could have 2 base stations, one is DM and both provide wireless service.

After 83.30 you would need to have 3 base stations for 2 to provide wireless service, and another is DM.

I do not operate any W80b's currently so I am just interested - why was this option removed, apart from to sell more equipment ?

Is it the same situation for W90 base stations (maybe it was never an option for DM to also provide wireless service)?

Also out of curiosity - can you mix W80 and W90 bases in a deployment?

Thanks
Jon
