Starlink has been licensed in Jamaica since October 2022, when the Office of Utilities Regulation backed Starlink Services Jamaica's applications for service provider and carrier licenses and the Minister of Science, Energy and Technology approved them. Service launched on the island later that year. For businesses it has become a practical way to connect sites that fixed broadband does not reach, and a useful second path when the main connection fails.
Hurricane Melissa, which made landfall in Westmoreland as a Category 5 storm on October 28, 2025, showed how much that second path can matter. Fixed and mobile networks were badly disrupted, and Liberty Caribbean, Flow's parent company, worked with Starlink's direct-to-cell service to provide emergency coverage while its own network was restored.
When Starlink makes sense for a business
- Rural and remote sites with no fiber and poor fixed wireless or DSL: farms, quarries, construction sites, villas and branch offices in the hills.
- A backup link for an office that depends on a single ISP, especially where fiber and mobile networks share the same poles and routes.
- Temporary sites such as construction projects and events, where running a fixed line is not worth it.
- Hurricane and disaster continuity, as part of a plan that also covers power and data backups.
When it may not be the best fit
- Sites surrounded by tall trees or buildings that block a large part of the sky.
- Businesses that need inbound connections, such as hosting a server or reaching cameras by port forwarding. By default, Starlink uses carrier-grade NAT (CGNAT), which blocks all inbound ports, and a public IP address is only available on certain service plans.
- Systems that send email directly over port 25, which Starlink blocks for all customers.
- Locations where reliable fiber is already available. There, Starlink usually works best as the backup rather than the main link.
Start with a site survey
Starlink needs a clear view of the sky, and Starlink advises that the dish should be fully unobstructed for best performance. The Starlink app includes an obstruction check: you hold your phone at the planned mounting height and it scans for trees, poles and buildings. Do this before you order, not after.
A proper business survey goes further. It looks at where the dish can be fixed securely, how the cable will enter the building and reach the network cabinet, where power and battery backup will sit, whether the roof is concrete or zinc, how the site is protected from lightning, and what Wi-Fi coverage the building needs once the connection is inside.
Mounting for Jamaican weather
Use a pole, wall or roof mount fixed into the structure, not just weighted down. Seal every cable entry point, and on coastal sites use stainless or galvanized hardware that will stand up to salt air. Wind ratings differ by kit, and Starlink publishes separate operational and survivable figures on each specification sheet. Starlink's own help center states plainly that the system is not designed to handle hurricanes. Treat the dish like any other rooftop equipment in your hurricane plan, with a named person responsible for securing or taking it down when a storm is coming, and putting it back afterward.
Power backup
A satellite link is only useful during an outage if it has power. Starlink lists the average power consumption of its Standard kit at 75 to 100 watts. Add your firewall, switch and Wi-Fi access points, then size a UPS (battery backup) for the whole chain, not just the dish. For longer outages, connect the UPS to an inverter system or a generator with an automatic transfer switch, and use surge protection on both the power and network sides. Test the setup by actually cutting the power.
Bridging Starlink into your office network
Starlink's own router is designed for simple setups. According to Starlink's support documentation, its Wi-Fi routers do not support port forwarding or firewall rules. For a business, the usual approach is to place your own firewall behind Starlink and let it run the network. Starlink's bypass mode turns off the Starlink router's Wi-Fi and hands the connection to your router. Depending on the kit generation, you may need Starlink's Ethernet adapter. Note that once bypass mode is on, a factory reset is the only way to turn it off.
From the firewall, the network is built like any other office: structured cabling to each area, separate VLANs for staff, guests, cameras and payment terminals, and managed access points for Wi-Fi. To reach other buildings on a farm or resort, use outdoor-rated cabling, fiber or point-to-point wireless links rather than stretching Wi-Fi.
Failover with your existing ISP
If Starlink is your backup, connect both internet services to a firewall or SD-WAN device that supports two WAN links. Configure health checks so the firewall detects when the main link fails and moves traffic to Starlink automatically, then moves it back when the main link recovers. You can also route specific traffic, such as voice calls, over whichever link is performing better at the time.
Plan around CGNAT. If staff or branch offices connect into your office by VPN, those inbound connections will not work over a standard Starlink link. Options include a public IP on an eligible plan, VPNs initiated from the office side, or a cloud-based remote access service. Test failover regularly, not just on the day it is installed.
Securing a Starlink-connected network
- Put a properly configured business firewall, such as a Fortinet FortiGate, between Starlink and your internal network.
- Never expose camera recorders, remote desktop or file shares directly to the internet. Use a VPN for remote access.
- Separate guest Wi-Fi, CCTV and payment systems from staff devices with VLANs and firewall rules.
- Protect the Starlink account with a strong, unique password, since whoever controls the account controls the service.
- Keep firewall and access point firmware up to date, and turn on logging so you can investigate problems.
- Physically secure the dish and cables, especially at unattended rural sites.
- Document the setup: settings, passwords stored in a password manager, and who to call when something fails.
A quick checklist before you order
- Run the obstruction check at the planned mounting position.
- Decide whether you need inbound access and, if so, confirm public IP availability with Starlink.
- Plan the mount, cable route and storm takedown procedure.
- Size battery and generator backup for the dish and all network equipment.
- Choose the firewall that will sit behind Starlink and plan bypass mode.
- If Starlink is a backup, plan and test the failover rules.
- Segment the network and lock down remote access before going live.
