What is a Router board 532 used for?

Please i just recieved a quotation on expansion of a Vsat internet link to WIFI users and Router board 532 was listed as one of the needed items.
I have not heard of this item before.
Please i need detailed explanation on its use for this network and why it is needed?

It’s a router. It’s an old model, it’s not made anymore, similar would be RB433AH probably.

Ok!
So how is it used in a WIFI network?
Thank You!!
