SEOUL -- SK Telink. a telecom service unit of South Korea's SK Group, will provide a new satellite communication service to domestic shipping companies by using Global Xpress (GX), a Ka-band broadband satellite network from Inmarsat, a British satellite telecom company.

GX offers downlink speeds of up to 50 Megabits per second download and up to 5 Megabits per second upload over compact user terminals. Operating in the resilient Ka-band, GX integrates seamlessly with L-band to deliver powerful and reliable connectivity anytime, anywhere.

The Ka-band is a portion of the microwave part of the electromagnetic spectrum defined as frequencies in the range 26.5–40 gigahertz (GHz). In satellite communications, it allows higher bandwidth communication. Smart ships based on GX are expected to revolutionize the landscape of ship design and operations. 

SK Telink said in a statement on Wednesday that it has introduced GX in South Korea to enhance the global competitiveness of domestic shipping lines. Accordingly, domestic shipping companies can establish a smart ship environment such as fuel-saving solutions and remote equipment inspection.

5G mobile networks partially overlap with the Ka-band. Through cooperation with Inmarsat, SK Telink changed GX satellite frequency that has already been set to resolve miscommunication and interference in frequencies with 5G mobile telecom services.

SK Telink promised to introduce Iridium Certus, an advanced new multi-service platform which delivers 100 percent global L-band connectivity and offers superior connectivity for maritime customers whether used as a standalone service or as a complement to VSAT (very small aperture terminal), a satellite communications system that serves home and business users.

L band refers to the operating frequency range of 1~2 GHz in the radio spectrum. It is one of the chief operating ranges used by various applications such as radars, global positioning systems (GPS), radio, telecommunications and aircraft surveillance.
