If it's a short hop (1-2km) I'd just use 802.11. You could go as cheap
as a couple consumer routers that support WDS or allow for the wireless
to work in client mode to industrial grade stuff by people like Westermo
and Pheonix.
Another approach would be to still use a wireless router/access point
but to add wireless to the TS product you're using. You can open up the
USB wifi dongle, cut it's antenna, and solder on a pigtail for a
external antenna.
If you go the 802.11 route you'll want to use external directional
antenna, be it yagi or dish (depending on the gain you need).
