Offshore Broadband for Coast Guard and Navy

Modern coast guard and navy offshore operations require a robust, high-capacity and low-latency communication infrastructure in order to optimize performance, situational awareness, command efficiency and response time for any event in the open sea.

We offer offshore broadband solutions for both vessel-to-shore and vessel-to-vessel connectivity, and enables essential applications such as:

  • Online video feeds from vessels to command centers on main ship or onshore
  • Instantaneous transfer of images, maps and video for quick response to any
  • Developing event and improved situational awareness
  • Ongoing voice & data communications, and video conferencing & surveillance
  • Workforce management
  • Environment monitoring
  • Employee infotainment

Our solution provides both point-to-point and point-to-multipoint connectivity for vessel-to-shore as well as inter-vessel communications.
For survivability, vessel-to-vessel communications can be independent of the vessel-to-shore connectivity. Thusly, situational awareness of the main vessel’s
command center remains intact even when connection to the land command center is broken.

RKTPL's VESSEL-TO-SHORE CONNECTIVITY SOLUTION

Vessels operating in the area of base station coverage have a high-capacity low-latency link available for any operational speed, vessel direction and sea condition. Vessels communicate with other vessels operating in the coverage area, as well as with other users connected to the onshore network. Handover between different sectors of the base station network is supported.

Stabilized high-gain antennas on the vessel compensate antenna azimuth and elevation for fast heading and pitch-and-roll movement of the vessel.
The stabilized antenna system ensures that the antenna beams are constantly aligned with the target when the vessel moves, by moving the antenna in opposite movement to the vessel.

Roaming between different shore base stations is supported. The stabilized high-gain antenna system on the vessel monitors its own position regarding the base station network and maintains the best base station as a pointing target.

Any vessel can communicate with any other vessel in the network as long the vessels operate in the coverage area and an IP link operates between the different base stations.

Mobility

The solution supports roaming between different sectors of the same base station network, as well as roaming between different base stations where user-defined.The solution provides the same level of performance for all vessel speeds up to 30 knots.

Latency

MW links have a typical latency of 25mS for single-hop one-way links. Guaranteed latency for a one-way link is max 50mS.

Range

The solution provides connectivity up to 60km for line-of-site (LOS) conditions and uses licensed frequencies.

Capacities

4G-based radio technology supports channel sizes of 5, 10, 15 and 20MHz. Capacity of 80Mbps per sector or 240Mbps per base station can be dynamically shared between the vessels that operate in area of sector/base station coverage.

Security

The solution supports 128-bit AES encryption algorithms and SNOW 3G.

Marine environment durability

Outdoor equipment on the vessels is protected inside an IP66-rated offshore radome.Vibration and shock absorbers assure long-life operations and durability.

Vessel equipment technical highlights

When deploying microwave radios with directional antennas on floating installations and vessels, the movements (heading, pitch and roll) of the hull with ocean waves and currents make the antenna beam point “off target” if not stabilized.The vessel is equipped with two Point Link Access stabilized antenna systems, which provide full 360-degree coverage without the need to utilize the highest positions on the vessel. Coordinates of the base stations (BSs) are saved in the Point Link application. GPS in Point Link’s starboard antenna provides the vessel’s location continuously. The Point Link system calculates continuously azimuth and distance toward the closest BS and maintains correct antenna azimuth and elevation.

Base station technical highlights

RKTPL 4G LTE solutions provide customers with connectivity for high-speed voice, video and data services for data terminals. The LTE standard, which was developed by the 3rd Generation Partnership Project (3GPP), is specified in its Release 8 document series, with enhancements described in later releases.
RKTPL delivers a comprehensive LTE solution that includes:

  • Base station eNodeB radios
  • LTE core network (EPC)
  • User equipment (CPE)
  • Network management system (NMS)

RKTPL'S VESSEL-TO-VESSEL(s) COMMUNICATION SOLUTION

The solution provides a high-capacity and low-latency communication link among a group of vessels. The selected “mother” vessel carries not only end-user equipment but also the 4G based base station with 360-degree coverage.

The other “daughter” vessels in the group have a system for automatic targeting of the mother vessel. Daughter vessels communicate with the mother vessel as well as with any other daughter vessel in the group. All parameters listed in the “vessel-to-shore” application describe previously are applicable for the “vessel-to- vessel” application except range. Range is roughly 20km due to low antenna height above the sea compared with land-based base stations.
