Starlink: notable performance, but with hidden limitations for professional users
The global deployment of Starlink, SpaceX's low-Earth-orbit satellite network, has transformed rural and enterprise connectivity thanks to its low latency. However, its adoption in corporate environments is revealing technical barriers that do not always appear in commercial documentation. The principal limitation is the use of Carrier-Grade NAT (CGNAT), which assigns private IP addresses and blocks direct remote access to servers, cameras or traditional VPNs — a critical restriction for infrastructure monitoring. Traffic management represents a further operational challenge. Unlike fibre connections, Starlink bases its performance on the shared capacity of the satellite cell; although Business plans offer priority, there are no minimum bandwidth guarantees (SLA), which makes it difficult to use in mission-critical services requiring 99.9% availability. In addition, software-based geographical restrictions on domestic antennas limit technical mobility in vehicles or vessels without specific plans, complicating operations in dynamic environments. Despite these shortcomings, the system stands out for its rapid deployment and latencies of between 25 and 40 ms, substantially outperforming geostationary systems. For small businesses in isolated areas, it is consolidating its position as a transformative solution, provided its technical limitations are accepted. The integration of Starlink into professional environments therefore requires a hybrid architecture employing external VPN tunnels, load balancing with 4G/5G networks, and proxy services to mitigate the absence of a public IP address. In conclusion, Starlink should not be regarded as a universal substitute for terrestrial infrastructure, but rather as a strategic component within a diversified network. Industrial users must analyse the operational 'small print' and plan complementary network solutions to compensate for the absence of service level agreements and addressing restrictions, thereby ensuring business continuity in remote environments.
