Ask HN: Communication between locations and avoiding existing infrastructure
2 by e-woke | 3 comments on Hacker News.
Hi I'm thinking about a possible project and Searching for an answer. Communication between distant locations 300 to 700 kilometres apart by avoiding existing infrastructure (routers, cables, DNS). What I need is standard TCP/ip services (web, ssh, samba,), voice, video would be nice. What technologies could be used and how reliable and safe (from outside intrusion) are they. What comes to mind is: To use modem (still uses existing phone lines).
