Reliable Cellular Connectivity for Vessels, Ports & Offshore Operations
Whether you're navigating coastal waters, operating offshore, or docked in a steel-clad port - poor cellular signal can disrupt daily marine operations. From delayed logistics communication to unreliable emergency access or navigation updates, weak signal slows efficiency at sea. Bolton Technical offers ICASA-approved signal boosters and passive repeater systems designed for the demanding maritime environment. Built to withstand harsh conditions and remote locations, our solutions keep your vessel, control room, or port office reliably connected - regardless of the network.
The Unique Challenge of Cell Signal at Ports and on Vessels
Marine environments pose unique challenges for maintaining strong cellular signal. From open waters to steel-walled ship interiors and remote harbors, signal strength can vary dramatically depending on location and conditions. As vessels move or port infrastructure expands, connectivity needs often shift. That’s why adaptable, high-performance solutions are essential. Bolton Technical’s WilsonPro systems amplify cellular signals by up to 32X, delivering faster 3G and 4G LTE data speeds - ensuring uninterrupted communication for crew, passengers, and operations across all maritime settings.
Reliable Marine Communication When It Matters Most
Clear communication at sea can save lives. Whether coordinating crew, managing logistics, or calling for help in an emergency, reliable mobile signal is non-negotiable. Weak coverage on vessels or in port can delay response times and compromise safety. Bolton Technical’s marine-grade signal boosters ensure dependable cellular connectivity across ships, docks, and offshore platforms - so you're always connected when it matters most. Don’t let poor signal become your weakest link at sea.

Our 4 Step Installation Process
Every professional repeater installation follows a proven 4-step process. Our certified installers are fully trained to ensure each installation meets our strict quality standards.
Step 1
Initial Review
Send us your building plans. Our team will create professional heat map designs showing projected antenna signal strengths per floor. We'll also generate a Bill of Materials (BOM) and a detailed cost estimate.
Step 2
On-Site Survey
We visit your building to conduct a comprehensive site survey using a signal test analyser. A signal expert will guide you through every step of the process to ensure accurate data collection.
Step 3
Design Proposal
Using the data from the survey, we refine the system design and generate a final, accurate BOM tailored to your site's needs.
Step 4
Installation Support
Bolton’s expert installation team handles the full setup, ensuring the system is installed correctly for maximum performance and reliability.

Maritime Signal Booster FAQs
Why is mobile signal important for maritime operations?
Strong cellular connectivity is critical for navigation, crew coordination, remote monitoring, internet access, and emergency communication. Without reliable signal, your vessel could face operational delays and increased safety risks.
Do cell phone signal boosters work offshore or at sea?
Yes. Marine-grade signal boosters are specifically designed to capture and amplify weak signals from land-based cell towers. They work best up to 40–80 km (25–50 miles) from the coast. Beyond that, performance depends on signal strength, weather conditions, and antenna height.
What are the main challenges of getting signal on boats and ships?
Distance from shore
- Block and weaken signal penetration.
- The ocean reflects and scatters signal waves.
- Storms, humidity, and salt air can degrade performance.
Our marine solutions overcome these with high-gain antennas, rugged amplifiers, and optimized system design.
Will a signal booster work at the marina or harbour?
Absolutely. Harbours and marinas often suffer from poor reception due to congestion and signal-blocking infrastructure. Our boosters provide stronger signal for docked vessels, ensuring better comms with land teams and smoother boarding processes.
Are marine signal boosters compatible with all South African networks?
Yes. Our signal boosters work with all major South African carriers including Vodacom, MTN, Cell C, and Telkom, ensuring full voice, text, and data coverage regardless of your provider.
Which types of vessels benefit from a marine signal booster?
Our solutions are ideal for:
- Fishing boats and trawlers
- Yachts and catamarans
- Commercial Cargo Ships
- Offshore Oil rigs and barges
- Coast guard, patrol, and rescue vessels
- Charter boats and ferries
Can a booster improve emergency communication at sea?
Definitely. When emergencies strike, being able to reach land-based rescue or support teams is vital. A marine signal booster enhances the likelihood of a successful call or data transmission when you need it most - especially for coast guard, private security, or medical emergencies.
How do marine signal boosters compare to satellite communication?
Marine signal boosters are ideal for nearshore communication, offering real-time coverage without subscription fees. For vessels sailing beyond 80 km offshore, satellite systems are recommended—but they come at a higher cost and with greater latency. Many operators use both.
How do I choose the best marine signal booster for my vessel?
It depends on the vessel size, number of users, distance from shore, and materials used in construction. Bolton Technical’s team of marine signal experts can provide a free assessment and recommend the ideal booster kit for your exact needs.
Can I use a marine signal booster while the boat is moving?
Yes. Our marine signal boosters are designed to function while your vessel is in motion. With a properly mounted marine-grade donor antenna and amplifier, your crew can maintain connectivity while cruising along the coast or between ports - ideal for ferries, trawlers, and coast guard vessels.
Are Bolton Technical’s marine antennas weatherproof and corrosion-resistant?
Yes. Our marine antennas are specifically engineered to withstand the harsh conditions of maritime environments. They are weatherproof, UV-resistant, and made from marine-grade materials that resist saltwater corrosion, high winds, and moisture exposure. This ensures reliable long-term performance, even in extreme sea weather.
