How to Reduce Costs on Voice and Data Communications Networks
- This article first appeared in the Railway-News magazine Issue 2 2022.
All rail operators face the same challenge: the need to enhance passenger safety and improve services for the constantly increasing number of passengers, while at the same time minimising costs and resources. It seems like an impossible task, but it isn’t: cost-efficiency without compromising quality is possible – operators can achieve breakthrough TCO in both CAPEX and OPEX while keeping the high quality and 24/7 availability of voice and data communications networks.
The solution is to rethink the network design and take the traditional indoor base station solution outside. Besides the outdoor base stations being small and compact and providing constant availability, an outdoor solution meets the demand for breakthrough TCO, while at the same time significantly reducing the complexity of the network.
Traditional Network Design
The network design has been the same for generations. Operators achieve network coverage with traditional indoor base stations consisting of an antenna system, transceiver, base station controller, power supply and a battery backup system. All components are typically doubled to provide maximum availability for mission and business-critical users. The drawback of this solution is complexity and unnecessary high costs.
