Now you're giving me a headache! As HipKat said above, any modern mesh network will be tri-band like his and mine both. One of these has to be a full-blown wireless router which could stand alone in your house or be combined with satellites. HipKat makes it sound like the Velop mesh are all routers. The satellite in the Orbi system is just a satellite and cannot operate without the master/router part.If you use a 2 piece mesh system, do you keep the modem/router in the middle? For instance, modem/router on the first floor, one mesh is on the second floor and the second is in the basement. Since I use a cell tower connection (living in the sticks) my T-Mobile gateway has to be on the second floor for best connection. So, what makes the most sense? Keep the gateway on second, place one mesh on the first floor and the second in the basement? Keep one mesh (attached to gateway with ethernet cable) on second floor and the second mesh on the first floor (or in the basement)?
If your T-Mobile gateway must be on your upper floor, if I were you, I'd place a satellite in your basement with a wired backhaul if possible. My two Orbis (one in basement and the other on my top floor) fill in all the dead spots in this house. With a mesh system, you can wander around your house with a wireless device and the mesh will seamlessly hand off the connection as needed. Supposedly (I have heard that) wireless extenders aren't so seamless and you can suffer drops while moving around.
So that is my recommendation: a mesh network with a wired backhaul if possible.
I am not sure about that. I think it has to slow down, depending upon the number of wireless connections it has to deal with. But with a wireless backhaul, you will have difficulty ever finding that limit.Second question: Unlike range extenders the speed does not degrade with mesh systems. Is this correct?
