The safe and reliable connection

What is Coast-Link™

  • the only highly available terrestrial broadband connection offshore
  • Wireless Broadband link from vessel to shore
Alex Bendler at work

Coast-Link ™ is one of the Wireless.Consulting GmbH developed concept for maritime broadband communication.

The most modern radio technologies make dedicated bandwith available for the most different applications for big distances. Ships are beiing provided with bandwith over a net of base stations on the coasts and offshore stations.

Whether Internet or Intranet, VPN or VoIP, Coast-Link ™ supports them as a Turnkey Integrator and net operator for your applications. We offer a broad-band radio connection within a defined area of coastal course.

Coast-Link™ presentation

Previously: Up and till now radio links were static an locally fixed connections


Ships can move within a defined sector and always hold a directional radio connection with the harbour.

Our specially designed antennas make it possible as well as a GPS/ compass linked rotor-system, which ballances out the movements/ turnings of the ship. Within the distance of up to 60 km ships can be connected to the base station.

With our own licensed systems even big range distances of 40 km can be realised with passive antenna systems.

A special design of the antennas is responsible for that and makes it possible even without the complications of a antenna system such as f.e. the rotor-track. Realised by the use of a licensed frequency band, ships can be broad band „on line“ around their port of registry or all along the coastal course. All the radio and operator licences needed will be provided by our company.


A network of base stations already offers a complete covering with our services in many areas. A multiple layer wireless infrastructure is able to offer different services to different groups of costumers. Tell us your target area and we will develope an individual and custom-made connection concept based on our Coast-Link™ net infrastructure.

Target markets

  • Sports boats and private users
  • Occupational navigation
  • Coastguard
  • Navy
  • Ferry services
  • Offshore wind park
  • Drilling rigs
  • Supply vessels

Target areas

  • The presently already available net cover in the Baltic Sea and the North Sea creates many synergies for different customer groups
  • Surface cover in the area of the Baltic Sea, to the west of Bornholm
  • Selective cover in the North Sea
  • Also inland waters can be supplied


  • Data connection - LAN linkage
  • Internet
  • Hotspot
  • Telephony
  • Mail
  • CRM
  • Terminal

Required area for the bandwidth?

more infos

Our technology covers distances up to 60 km from one side and nearly 120 km from both sides. For that we install own transmitters on strategic locations to be able to provide the range for the ships in defined sectors.

Our system reaches bandwidth for the up- and downlink of 20/ 10Mbps. With our intelligent Coast-Link™ Unit several ways of connection can be adequately combined according to their purpose.


The better alternative

Your satellite system doesn't provide enough bandwith?
Your satellite system has a data volume limit?
Your satellite system disposes of an insufficient availability?
Your satellite system has too long signal terms, latency (Ping)?
Your satellite system produces too high monthly costs?

We would like to provide you an offer for a custom-made solution as a supplement and/ or separation of your existing system.

A hybrid use is also possible with our scaleable Coast-Link ™ Onboard Unit f.e, as a backup or for the subdivision of the services. Over Loadbalancing several transference ways can be route on with our Coast-Link ™ Onboard Unit as well.
