Your mobile connection partner at sea

Quality voice and data is essential for staff working on ships when they are either at sea or in port. In the modern world, mobile data is used for communicating with family, business and entertainment. Because of the structure of the ship, providing this service can be very expensive. The steel hull blocks mobile signal like a faraday cage. There are many small rooms inside the ship all surrounded by metal walls. The ship can be far out to sea. All this limits the options available for data services on the ship.Often customers have to  rely on satellite which is expensive and slow.

How to ensure the best mobile signal on a ship?

 

Enable mobile signal 40Km from the mobile operators’ towers on the shoreline.

Ships, yachts and barges all have to be able to communicate while at sea. Mobile signal can propagate out to sea at least 30Km from the coastline (where there is a base station). A repeater system can take this weak mobile signal, amplify it, and send it around the inside of the ship. This is the most cost effective way to bring the mobile signal from all the operators inside the ship.

Stella Doradus repeaters ensure full mobile signal at least 30km out to sea. Solutions are available for both mobile phones and routers. The product range enables customers to stay connected without the need of expensive satellite systems, or at least reduce the dependence of the satellite.

 

Solution that will provide signal in all areas below deck.

Ships are robust steel structures, built to endure harsh environments at sea. Space is at a premium and the inside of a vessel generally consists of narrow corridors and small rooms. The steel walls make it impossible for the mobile signal to penetrate, resulting in no mobile signal below the deck. Stella repeater system is a passive DAS solution. This allows the propagation of the signal inside the ship using passive elements like splitters. This is a very simple and cost effective way to provide coverage in all the small separated areas within the ship.

 

Ensure full mobile signal is delivered to 5G/4G/3G/2G routers below deck.

High speed, stable data is essential for modern communications on ships. High-end 5G routers are available which provide speeds of up to 1Gb. However, down in the comms room, deep within the hull of the ship, these routers often receive very poor mobile signal. Many cables must be connected from the router to outdoor antennas high up on the mast. Two problems result from these long cables. 

The first is that the signal is lost in the long cables.

 

Stella’s RouterAmp combats signal loss over long cables by adding 15dB extra gain. This ensures that the router receives full signal, allowing it to work at full capacity.

The second problem is that these MIMO routers rely on multiple antennas to achieve these very high speeds. For the latest 5G routers, with 4 radios in them, up to 16 antennas are required. This means 16 cables need to be installed from the router to the mast.  

Stella's RouterAmp reduces the number of required cables by up to a factor of four. For example, a router with 16x antennas (4xSIM’s) now only requires 4 external cables and antennas. Stella’s RouterAmp is compatible with all routers and amplifies the signal from all operators.

 

Ensure US, Caribbean, Europe and African signal support for transatlantic journeys

Ships and yachts traveling transatlantic require equipment that can accommodate US / Caribbean frequencies as well as European and African frequencies to enable mobile signal within the ship. Stella has a range of repeaters and router amplifiers that seamlessly switch frequencies to support mobile signals on both sides of the Atlantic.

 

Cost efficient, environmentally friendly solution

Communication at sea is very expensive for ships and yacht owners. Satellite costs can amount to thousands of Euro per month. A cost effective communication system is required within a ship to drastically reduce voice and data costs on board. Stella Repeater Solutions allow staff and passengers to use their phones for up to 30 km from the operators’ masts on land for voice and data. The Stella Repeater System operates as a passive DAS system and is very efficient once installed. The antennas use no energy to transmit the signal and the repeaters use about the same energy as a lightbulb.

Pre-Installation Support

Building plans can be uploaded to the Stella Online Planning Tool to plan and troubleshoot the repeater installation layout. This helps the installer to provide more accurate quotations as only the required material is purchased, and also saves the installer time when doing the installation. 

Post Installation Management

Stella iRepeater Systems can be fully monitored online using Stella’s cloud based, remote management system. The system can be remotely monitored and calibrated, ensuring it is always performing at the optimum level.

FAQ

After the initial installation, the Stella repeater system costs very little to run. The antennas that distribute the signal do not require any electrical energy. But by far the greatest saving is in the reduction of satellite costs. Satellite is now required only when very far out at sea ( >30Km from the operators’ masts on land), saving sometimes thousands of Euro per month on satellite costs.

The mobile operators use different frequencies in the USA/ Caribbean compared to Europe. Therefore, Stella has a dual repeater system to provide signal wherever you are in the world. As the ship enters American waters, the repeater automatically switches from the EU repeater to the US repeater and the US signal is seamlessly available to all staff and equipment on board.

Many large ships have steel hulls and this prevents the signal from entering even when they are very close to the operator’s mast. With the Stella Repeater System, the external antenna up on the mast receives the signal from the operator and passes it inside the ship via the internal antennas, to provide full mobile voice and data signal to all people on board when in port and out at sea.
