Default WiFi Link from top of tower

Maybe I am missing something here, but if you put a wireless router at the

You can can talk to the router locally over the air without the need for a
cable connection.

there are some practical details. For one thing, a lot of wireless
access points don't provide full control functionality over the wireless
port (for security, among other reasons). For instance, changing the
RF channel number is trickier "over the air".


The other thing has to do with available data bandwidth.. 802.11 PHY
is essentially a half duplex protocol (i.e. it doesn't Tx and Rx at the
same time). If you set up two units back to back, you can run the
second link on a different channel for your "shack to tower" link, so
those packets don't have to go over the air on the "tower top" unit.


Lots of possibilities, lots of ways to do it.
