Internet on a Private Island
Connectivity has changed island ownership more than any other technology in the past decade. Reliable high-speed internet now makes extended stays and remote work practical in locations that were previously seasonal.

The main options
- Low-earth-orbit satellite, now the default in most remote locations
- Cellular links with an external antenna where a mast is within range
- Point-to-point microwave from a mainland site, for fixed high-capacity links
- Geostationary satellite, still used as a backup in some regions
Practical planning
- Confirm service availability and licensing in the specific country
- Budget continuous power for the terminal and networking equipment
- Protect equipment from salt, humidity and lightning
- Consider a second path for redundancy where work depends on it
- Plan Wi-Fi coverage across separate buildings with outdoor-rated links
Why it affects value
An island that supports remote work can be used for months rather than weeks. That change in usability is increasingly reflected in what buyers are willing to pay.
