American Network Operators' Group" <nanog@nanog.org><br><b>Sent: </b>Saturday, August 3, 2019 2:30:43 PM<br><b>Subject: </b>Best ways to ensure redundancy with no terrestrial ISPs<br><br><div dir="ltr">Hi all,<div><br></div><div>A friend of mine is trying to set up a network in a location where there is no fiber (or copper) for many miles. As bandwidth requirements are low (<1M for the foreseeable future) but uptime is important, he was looking at using multiple cell modems from separate carriers as redundant uplinks. I am concerned that different cell carriers might be using the same transport providers to a given tower, so that wouldn't be truly redundant. Another option would be using a satellite provider as a backup for cellular. (The high latency that comes with satellite is not an issue.)</div><div><br></div><div>A fixed-radio solution would likely be too expensive upfront as it would require building towers.</div><div><br></div><div>Am I missing any other options or considerations?</div><div><br></div><div>Thanks,</div><div>Ross</div></div>
