Large scale audio over IP systems for public transportation

The Challenge

Providing professional audio solutions to modern transportation companies is a complex undertaking. Light rail, subway, regional railway, and even “people mover” services demand flexible, secure, and reliable solutions for delivering announcements, music, and emergency calls to specific areas, both fixed and mobile. One railway network might include hundreds of stations, together supported by dozens of audio servers and priorities and an array of different voice announcement systems.

As a systems integrator looking to propose a complete audio system for such customers, you’ll be asked to meet a series of stringent requirements. Interoperability with management applications is critical, as is the ability to deliver specific notifications and emergency messages in a timely and targeted manner, according to both schedule and message priority. While the many zones involved may cover a countrywide geographic area, your solution must enable centralized control. It must also feature monitoring and reporting capabilities that help to ensure uptime across all zones.

Because such extensive transportation networks and companies typically are public companies, they often will require that you answer stringent approval about industrial cycle for testing, production, and the supply chain. You’ll need to meet high standards in terms of reliability and performance, and you will be asked to provide reference implementations that demonstrate that the technology you propose has a strong track record.
