As a network specialist at Livewire Digital, we understand the importance of seamless connectivity in today’s globalized world. In this article, we will explore the incredible capabilities of Inmarsat’s GX network, Fleet Xpress, Inmarsat L-Band Satellite Network, Satellite Access Stations, and GX Voice. We will also discuss how Livewire Digital can help integrate these satellite services for your organization.

Global Xpress (GX): Unleashing the Power of Ka-band

Global Xpress is Inmarsat’s geo-global network of geostationary satellites operating in the Ka-band. This cutting-edge technology forms a critical part of a hybrid L-band/Ka-band satellite and ground network, offering managed and leased services to Inmarsat’s customers worldwide. GX ensures high-speed, reliable, and global connectivity, making it ideal for industries such as maritime, aviation, government, and enterprise.

Fleet Xpress: Bridging the Gap with GX and ELERA

Fleet Xpress is Inmarsat’s customer-facing maritime offering, which combines the strengths of GX and ELERA networks. It provides a comprehensive and integrated solution for the maritime industry, offering high-speed data, voice, and application services. With Fleet Xpress, vessels can stay connected even in remote regions, ensuring efficient operations and crew welfare.

Inmarsat L-Band Satellite Network: The Evolution from BGAN

The Inmarsat L-Band Satellite Network, formerly known as Inmarsat’s Broadband Global Area Network (BGAN), has a long history of providing reliable satellite connectivity. It offers portable and versatile communication solutions for users on the move, making it a valuable asset for industries requiring mobility, such as emergency response teams and journalists in the field.

Satellite Access Station (SAS): The Gateway to Connectivity

A Satellite Access Station (SAS), also known as a gateway or ground station, plays a pivotal role in satellite communication. It serves as a facility that communicates with satellites to provide connectivity between user terminals and the core network. SAS facilities ensure that data flows seamlessly between satellite and terrestrial networks, enabling users to stay connected no matter where they are.

GX Voice: Premium Telephone Services with Livewire

GX Voice is an Inmarsat-managed standard telephone service offered in Inmarsat-owned bandwidth outside of the customer’s allocated bandwidth. This service is charged on a post-paid basis and relies on the Network Service Device (NSD), which is delivered by the NSD’s Cisco Call Manager Express (CME) capability. GX Voice ensures reliable and high-quality voice communication for critical operations.
