Sure! I saw startyourownisp.com on HN years ago, and once I moved here I remembered that starting an ISP was actually a thing. I started a wireless ISP (WISP). The rough process is:
- Find the customers*
- Find somewhere to broadcast from*
- Find a wholesale fibre provider*
- Register with your country's regulator & read a bunch of laws
- While you are doing the above, learn about networking. Get this right before you launch, then forgot about it. Post-launch all problems will (hopefully) be non-tech related.
And also lots of good old-fashioned business cash-flow spreadsheets.
I really like enjoy it (even though it can be stressful) because:
- I like geekery
- I like business (even thought it can be stressful)
- I like being in nature, and this one of the few lines of work that combines the OSI model & chainsaws.
- I like having a reason to meet people in my area. Great way to make friends.
- This area really needs it. There is fibre in the villages, but lots of people live & work on remote patches of land. The service I provide really makes a difference to their lives.
It don't think it'll necessarily make you rich, but it may give you a meaningful livelihood if you have the market for such a service.
* You kinda need to do these three simultaneously, because they all need to be in the same location. At some point I just had to commit to one of the three and hope that everything else fell into place.
