| Have you looked into LRE , Long range ethernet.
It uses a 25 pair amp champ out of a router with ethernet ports.
Connect a pabx to a LRE router on each side and patch the ethernet ports to your wireless connections.
We have used these at some campuses with only copper infrastructure but just to send data , not sure of any QOS on the routers.
I would imagine it would just be a firmware version. |
