We have something of the sort runing between a Thai university and the National University of Laos. Purpose is to connect the Lao University to the Thai university and research network. Expected speed is 10Mbps. You can email me personnally at the end of April, then I will be able to give you more details :) I will not go to Laos before one month, until then I cannot remember the brand of the radio equipment. National University of Laos used to have their network with remote campus locations build over air, using public grade WiFi access-points, they were not really stable. Regarding your set-up, I think it is nothing different from: LAN<->BSDrouter<-1->DSL only the link between the BDSrouter and the DSL provider is a bit longer. On your concern about traveling 10KM at 3:00, you can locate the BSDrouter at either end of the radio link, it will not change much of the volume of traffic crossing the radio link, unless the BSDrouter is also doing some heavy proxying. So you could locate the BSDrouter at the closest end to your home. Only one remark, if that BSDrouter is to serve as DHCP and such, it is best located at the LAN end: if the radio link goes down, the clients on the LAN can still access their DHCP server, and they can still communicate inside the LAN. If the BSDrouter is located at the DSL end and the radio link goes down, the clients in the LAN will not manage to get IP and will not be able to communicate among eachothers.
