Case Study: VSAT Mobility Network for Vehicle-Based Connectivity Solutions
Doha, Qatar, May 12, 2025 - In today’s rapidly evolving digital landscape, ensuring seamless and reliable connectivity is paramount, especially for mobile platforms. This case study explores the integration of a VSAT (Very Small Aperture Terminal) mobility network on vehicles, designed to provide robust cellular backhauling for private data networks and general internet connectivity. The system leverages an innovative blend of satellite and terrestrial technologies to deliver continuous and high-speed connectivity to serve the needs of Government and VIP users.
System Overview
The core of this advanced connectivity solution is a vehicle platform equipped with a GEO VSAT terminal, LEO connection via flat panel antenna, and GSM radio units, all integrated with an SDWAN (Software-Defined Wide Area Network) router. The combination of these technologies ensures that the vehicle remains connected even in the most remote and challenging environments.
VSAT Terminal (GEO)
The VSAT terminal operates on GEO satellites, specifically utilizing the coverage area of Es’hail-1 MENA beam on the Ku-Band. This provides extensive regional coverage, ensuring that the vehicle can maintain a connection across the Middle East and North Africa (MENA) region. The TDMA network for GEO connectivity is operated from the Tier-4 certified Es’hailSat teleport, ensuring reliable and efficient management of bandwidth and resources.
LEO Integration
In addition to the GEO-based VSAT terminal, the system incorporates connectivity from a constellation of low Earth orbit (LEO) satellites that offer global coverage. LEO systems offer low latency and high-speed capabilities complement the GEO satellite system, providing a hybrid solution that enhances connectivity, especially in areas where traditional satellite coverage might be limited.
GSM Radio Units
To further augment the connectivity options, GSM radio units are integrated into the vehicle platform. These units enable cellular backhauling, leveraging existing terrestrial cellular networks for data transmission. This multi-faceted approach ensures that the vehicle can seamlessly switch between satellite and cellular networks, optimizing connectivity based on availability and performance.
Flat Panel Antenna
A crucial component of the mobility network is the Flat Panel Antenna (FPA). The FPA is designed to meet low profile requirements, ensuring that the antenna does not significantly alter the vehicle’s aerodynamics or appearance. This makes the solution ideal for various vehicle types, from commercial trucks to emergency response vehicles, where a discreet and efficient antenna system is essential.
SD-WAN Router
The integration of an SD-WAN router within the system enables dynamic management of network connections. The SD-WAN router intelligently routes traffic across the available connections, whether GEO satellite, LEO constellation, or GSM, ensuring optimal performance and redundancy. This capability is critical for maintaining high levels of service availability and quality.
