1️⃣ Comparison of Maritime Internet Solutions

The right internet solution for a ship depends on multiple factors, including voyage routes, bandwidth requirements, and budget. Some vessels need global coverage with guaranteed reliability, while others prioritize speed and low latency. Older VSAT systems remain widely used, but newer low-Earth orbit (LEO) solutions such as Starlink are changing the landscape. Nearshore vessels can take advantage of cellular networks, and many shipowners are now adopting hybrid approaches to balance cost and performance.

The table below provides an in-depth comparison of the main maritime internet options available today.

ShipUniverse: Maritime Internet Options
Internet Type	Coverage	Speed	Latency	Monthly Cost	Best For
VSAT (GEO)	Global, except extreme polar regions	1–50 Mbps	600–800 ms	$500–$25,000+	Large commercial vessels, deep-sea operations
LEO Satellite (Starlink, OneWeb)	Expanding global coverage	50–200+ Mbps	20–50 ms	$250–$5,000+	Cargo ships, passenger vessels, crew welfare
4G/5G Nearshore	Coastal regions (up to ~30 km offshore)	10–300 Mbps	20–100 ms	$50–$500	Ferries, regional shipping, offshore supply vessels
Hybrid Systems	Global with nearshore optimization	Varies by network priority	Varies	$1,000–$10,000+	Shipowners optimizing cost and redundancy
L-Band (FleetBroadband, Iridium Certus)	Truly global, including polar regions	100 kbps – 700 kbps	500–1,000 ms	$500–$5,000+	Safety communications, emergency backup

Each option has advantages and trade-offs in terms of speed, latency, and cost. Below is an overview of the five primary types of maritime internet solutions.

VSAT (Geostationary Satellite Internet)

VSAT has been the industry standard for decades, using satellites positioned in geostationary orbit, approximately 36,000 km above Earth. These satellites provide wide coverage, making VSAT a reliable option for ships traveling across major ocean routes. Speeds typically range from 1 to 50 Mbps, though premium plans offer more. One drawback is the high latency of 600–800 milliseconds, which can make real-time communication challenging.

VSAT hardware requires a large parabolic antenna that automatically tracks satellites. Equipment costs can range from $10,000 to $50,000, with monthly service fees anywhere from $500 to over $25,000, depending on bandwidth needs. While VSAT is a proven and widely available technology, its high costs and latency make it less appealing compared to newer alternatives.

LEO Satellite Internet (Starlink, OneWeb, etc.)

Low-Earth orbit (LEO) satellite networks such as Starlink and OneWeb provide an alternative to traditional VSAT systems. These satellites operate at much lower altitudes, between 500 and 1,200 km, which allows for significantly reduced latency—typically 20 to 50 milliseconds. The result is a faster, more responsive internet experience that supports applications like video calls and cloud-based operations.

LEO solutions offer speeds of 50 to 200+ Mbps, with expanding global coverage. Unlike VSAT, LEO terminals are compact and easier to install. Pricing varies, but Starlink Maritime, for example, has hardware costs of around $2,500, with monthly service fees starting at $250 for basic data plans and going up to several thousand dollars for high-usage tiers. While LEO networks are still growing, they are rapidly becoming a preferred choice for cargo ships and commercial fleets looking for high-speed, lower-cost connectivity.

4G/5G Nearshore Connectivity

For ships that operate close to shore, 4G and 5G networks provide the fastest and most affordable internet access. These networks rely on cellular towers and can reach vessels up to 30 km offshore under good conditions. Speeds can range from 10 to 300 Mbps, with latency as low as 20 milliseconds.

One of the biggest advantages of 4G/5G is its cost-effectiveness. Monthly data plans are significantly cheaper than satellite services, often costing between $50 and $500, depending on data usage. Many ships use marine-grade antennas and signal boosters to enhance coverage and maintain a connection farther offshore. However, once a ship moves beyond range, a satellite-based solution is required. This makes 4G/5G a great option for ferries, regional cargo ships, and offshore supply vessels that operate near coastlines.

Hybrid Systems

Many ship operators are now adopting hybrid internet solutions that combine satellite and cellular networks to optimize cost and performance. A hybrid system may use LEO or VSAT for deep-sea connectivity while automatically switching to 4G/5G when nearshore. Some hybrid solutions also include multiple satellite services, providing redundancy in case one network becomes unavailable.

Hybrid systems allow for cost savings by prioritizing lower-cost networks when available. A typical setup might involve a Starlink terminal for high-speed connectivity, a VSAT system as a backup, and a 4G router for nearshore areas. Monthly costs range widely depending on the selected services, from $1,000 to over $10,000. These setups are ideal for shipowners looking to balance cost, coverage, and reliability.

L-Band (FleetBroadband, Iridium Certus, etc.)

L-Band services such as Inmarsat FleetBroadband and Iridium Certus provide global coverage, including remote polar regions where other satellite options may not be available. These systems operate at much lower frequencies, making them highly reliable in all weather conditions. However, they offer very low speeds—typically between 100 and 700 kbps—making them unsuitable for general crew internet use.

L-Band is mainly used for safety communications, emergency backup, and low-bandwidth operational data. Monthly service costs range from $500 to $5,000, depending on usage. While it is not a primary solution for high-speed internet, it remains an essential backup system for ships operating in extreme environments or those requiring guaranteed connectivity for emergency situations.

2️⃣ Technical & Cost Considerations
