Mesh systems: Do they work in series?

[Paulo da Silva]

Hi!

Do mesh wifi systems work in series, i.e. along a big distance?
I may need 3 to 4 units.

A----------B---------C[--------------D]

A is where the connection to the modem/router is.

Thanks for any help/comments.

They can.

Mesh networks work in a "mesh" organization, usually with paths defined ad-
hoc as nodes engage and disengage with the network.

Your example /might/ look like...

B
/ \
A \
\ D
\ /
C

as far as interconnection and mesh distance metrics are concerned.

I don't think this scenery would happen because of the distance/walls
involved. This is a long place with a relatively small global area.

Thank you very much.

Yes, but it'll affect performance. Both yours, and the performance of
adjacent WLAN installations (neighbors).

Thanks Marc.
Do you have any idea on how much the performance is affected by each
unit in the series?

[Marc Haber]

Imagine a frame being in the air three times instead of once and
taking up bandwidth there. The transmission between B and A is unlikey
to affect the C-D hop if it's sufficiently far away, but I'd expect
the transfer rate to be in the reason of half the maximum.

Wifi is a kludge, and Wifi Mesh is putting a patch on the kludge.

OK Marc.
Thank you for your enlightenments.

Depending on the layout of the area, perhaps something like this:

https://community.ui.com/stories/Covering-a-400000-sq-ft-factory-with-2-UAPs/bc502aa6-93b9-43f4-9b37-1581d8e626f0

I used that method to cover a large area and it worked out well, but it
was in a single large open space (like the warehouse in the example) with
not much in the way of interior walls.

If there is any way around it, I suggest you find it. The latency will make any kind of real-time communication unbearable. When the news wants to talk to you, for instance, they ask you to plug your shit into an ethernet port because even 1 wireless device is enough latency to make conversations flow in the most annoying fashion.
