Orbi voice add on to RBK50

[Nosher7]

Hi. Recently purchases the RBK 50 system and am very happy with it. Keen on adding the RBS40v ( orbi voice satellite ) but I've been reading some conflicting information online. Will adding a AC 2200 orbi voice reduce my entire network to AC2200 or is it just the router to unit itself that operates at AC2200 while the paired RBS50 operates at the advertised AC3000? Thanks

Its just the RBS40V to the base unit. All the RBS50 units will still function with the full 1766mbps backhaul.
