Does adding in orbi satellite RBS40 (AC2200) slow down the overall speed of the network?

Hi there

I have the RBK50, however I plan to add the RBS40 as I need to increase the range.

I was wondering if I add this, given that its a star topologu would this slow down the overall system? 

(i.e. the other satelitte I already have running at AC3000 will still be able to perform at that speed?)

Just wanted to check that the overall system doesn't run at the speed of the lowest rated satelillite.

Thanks
