SeaWire RouDem is a combination of an auto-rotating, directional antenna and a modem that provides Internet connection via the mobile network. When operating the antenna will automatically shift between the operator base stations selecting the best performing base station.
The connection to the Internet is obtained via a data SIM card, which you insert into the RouDem. The RouDem is designed for installation above deck at the highest spot possible on a standard antenna pole. Additionally, the RouDem has an integrated WiFi router and battery giving over 8 hours of operation.
SeaWire Pro is a premium plug-n-play wireless broadband solution for seafarers who is dependent on fast and stable internet connectivity. When operating, one of the antennas will connect to the best performing operator tower while the other antenna will scan for new operator towers to connect to. While not in scan-mode, both antennas connect simultaneously, doubling the data speed and offering connection redundancy. The SeaWire Pro is IP66 rated to withstand the environment at sea and is primarily designed for commercial vessels.
MiWire’s products contain a patented intelligent rotating directional antenna that points to the most optimal operator base station, controlled by our embedded software algorithm. MiWire’s auto-rotating, high-gain, directional antennas not only automatically locate the best operator base station. Our solutions also scan and memorize the network infrastructure through an advanced, patented software algorithm to ensure maximum data speed, even when changes in the network infrastructure is made. We have developed plug-n-play solutions in which installers do not need to have knowledge of the network infrastructure in order to install. MiWire ensure high performance data speed, wherever you are. A
We collect data from every operating antenna at least once per hour, including GPS position and signal strength.
The collected data is used to continuously improve our algorithms and to simulate coverage, enabling us to predict expected network performance for vessels on new routes.
Even in areas without prior measurements, our advanced simulation algorithm, combined with public cell databases, allows us to generate accurate coverage maps.
Our Route-Based Coverage Analysis uses a vessel’s historical sailing routes to simulate expected 4G/5G coverage, connection quality, and data costs along the journey.
By combining real-world data with our advanced prediction models, we deliver a reliable overview of how SeaWire will perform on any route—enabling operators to plan with confidence and avoid unexpected connectivity issues.
The SeaWire Pro system combines two long-range, auto-rotating directional antennas (SeaWire RouDem) with a Below Deck Unit (BDU) that manages and distributes incoming network traffic. During operation, one antenna connects to the strongest available operator tower while the other scans for better options. When not scanning, both antennas operate simultaneously, boosting data speeds and ensuring connection redundancy.
SeaWire Pro delivers high-speed internet via the mobile network, even far offshore, using standard data SIM card/eSIM. Each antenna unit features an integrated Wi-Fi router and a built-in battery, providing several hours of operation even during power interruptions.

The package content DOES NOT include cables. The length of the cables depends on the location for installation. You need two cables; one for each antenna. Download the System Configuration to get an overview.
Cable specifications:
Network cable type: S/FTP CAT7, UV- and water resistant, double shielded, grounded
Connector 1: RJ45 (male), CAT7 FTP, grounded
Connector 2: RJ45 (male), CAT7 FTP, grounded
Length: the length of the cables depends on the location for installation (max. length 100m)
For best performance, install the antenna at the highest available point on the vessel, ensuring an unobstructed 360° view whenever possible. Position it with maximum separation from other radio communication equipment to reduce interference. The mounting bracket is designed to fit a pole with an outer diameter of Ø38 mm (1.5”).
Each RouDem will create its own WiFi hotspot. In most cases it is recommended to extend the WiFi signal coverage by connecting external WiFi equipment to the LAN port in the BDU. In that way you can easily distribute the WiFi signal to where it is needed.

Many have heard of a directional antenna that you have to manually rotate toward an operator base station. Many have also heard of systems in which you can transform 3G, 4G and 5G to a WiFi hotspot. MiWire took these components, and made it intelligent. We invented an auto-rotating, directional antenna with a built-in modem and advanced software algorithm.
And how does this differentiate to standard options? With the auto-rotating directional antenna we avoided users needing to be experts to find the best operator base station and manually point the antenna towards it. With the built-in modem, we avoided signal loss in cables. And with the advanced software algorithm we made our RouDem intelligent: it scans and memorizes the network infrastructure, so when changes in the network are made, it automatically connects to another base station.
We hold three different patents on this invention, and it ensures that people living and working at the edge of the mobile network with no alternatives to gain internet access, do not have to suffer from slow data speed.
MiWire is our company name, and it also became our first brand. The MiWire brand holds our land-based solutions, which was our first product line and mainly fixed installations. Our SeaWire brand was then developed from the land-based solutions. First, we needed to improve the RouDem to a IPX6 rating for it to withstand the environment of the sea. We further developed the hardware and the software systems, thus enabling the RouDem to become more dynamic for the constant mobile use all around the world. To support this, we developed the GlobalWire data subscription, which is a subscription for a SIM-card with operators all around the world, which is ideal for a seafarer.
You know the solutions are for you, when a fast and stable internet connection is important for your personal or professional life. When you live or work at the edge of the mobile network coverage. When you constantly have a bad internet connection, no matter how much you do to improve. MiWire offers you cost-efficient solutions that provide fast and stable internet connection - wherever you are. Simple as that.
When deciding whether you need a single unit solution or a pro solution with a two unit configuration + a control unit, you need to consider a few things. First of all, the more people who will use your internet connection, the bigger capacity is needed. The more units you have, the bigger capacity you can gain. If your internet connection can never fluctuate, for example when the RouDem needs to connect to a new base station, you need an extra unit for redundancy. Here you can insert SIM-cards from two different operators, thus gaining redundancy. Further you can also achieve redundancy by connecting fiber or satellite connection to the Pro’s control unit. In short, for medium to big corporations, it is a good idea to choose a Pro version.
