In some areas, you can also get some wireless across the border. If you have a direct visibility and have a friend at the other end, Bob’s your uncle. Doesn’t even have to be a friend; I can imagine ISPs in Slovakia and around other borders to happily take their share of customers. With a better antenna, maybe even 3G could work.
Then there’s the satellite internet, with high-speed high-latency downlink and low-speed local-internet uplink; these services existed some time ago, not sure how/if they work now and how much they cost.
