China is becoming the pioneer of dedicated broadband for critical communications

Asia is a key market for critical communications systems. Many developing countries are investing massively in transit systems. Critical communications in the wider Asia market have developed quickly during the past decade as many countries and areas moved to digital solutions. Multiple digital technologies including TETRA, Project 25 (P25), Digital Mobile Radio (DMR) and Professional Digital Trunking (PDT) have been adopted in the Asian market.

The transport sector, one of the most active markets for critical communications, is preparing for future evolutions. Some metro companies and airports are implementing hybrid networks by using TETRA for voice and broadband for data. In many regions including Asia, rail operators are still realizing advances in cellular technology. China is becoming the pioneer of dedicated broadband for critical communications with advances in broadband trunking standardizations and dedicated network allocations.  BelFone Prochat PoC system is Push-to-Talk system that use VoIP technology over the existing cellular network to offer PTT one-to-one private calls or one-to-many group calls like two way radio. It provide half-duplex or duplex communication through a single, multifunction device.

Broadband brings significant advantages for both public-safety and cellular communications, including higher data speeds, lower latency and high spectrum efficiency. Deploying this technology on public transport enable emergency services to share interactive, allowing faster situation analysis and response times.
