Metro Line 1, a 19.7 km rapid transit project and the first urban rail transit system in Ho Chi Minh City, required reliable mobile connectivity to support daily operations and passenger experience across underground and elevated sections.

The project required seamless multi-operator coverage across the metro line while ensuring high capacity, low latency, and consistent performance in complex urban and underground environments. Existing infrastructure lacked sufficient coverage, risking communication gaps and poor user experience. PROSE addressed this by deploying EPIC DAS, integrating multi-band support (UMTS2100, LTE1800, LTE2300) with MIMO technology and enabling efficient multi-operator network sharing.
