  • DMR gets attention and with good reason
    Previous articles in Radio Comms Asia-Pacific have presented varying views on DMR technology and may have led some readers to believe that DMR is another digital radio ‘flash in the pan’ that has no place in an already busy Australian digital radio landscape.
  • Airport upgrade
    Lyon-Saint Exupéry airport has selected Sepura Tetra terminals for its radio and communication needs following the recent deployment of a new digital communications system that replaced four legacy analog networks.
  • Updating US network
    Cumberland County, Tennessee’s PlantCML CORP25 land mobile radio network in the US includes a Zetron Advanced Communication radio dispatch system. It is providing the county with improved 9-1-1 emergency dispatch functionality and better radio coverage and interoperability among the public safety agencies it serves.
  • Project: Updating NZ rail
    In a move to improve system reliability and flexibility, while providing a platform for mobile data capability, KiwiRail, the organisation responsible for managing New Zealand’s rail network, has begun a major upgrade to the nationwide radio system used to help the safe movement of trains and track workers around the country.
  • Rail crossing safety
    New technology by La Trobe University, to have cars and trains ‘talking’ to each other, could save an average of 37 lives every year and an estimated 100 million dollars, by eliminating rail crossing collisions, especially in rural and regional Australia.
  • The increasing presence of Project 25
    Papers on various radio technologies were presented at last year’s RadioComms Connect event in Melbourne. This article looks at another of the technologies discussed - P25 - and charts some of its evolving features.

  • Networking Voice Communication & Control Systems
    Facing the challenge of networking voice communications and control systems in a mission critical environment requires careful planning, product selection and implementation. This technical paper steps through a real life case study which culminated in a hybrid voice communication and control system (VCCS) with a fully digital, totally non - blocking voice communication system with a distributed, parallel operating core that provides high reliability, fault tolerant voice communications.

  • A serving of digital soup
    In 2009 we’re all familiar with the term ‘digital’. We now have digital TV, digital set-top boxes, digital radio, our music library is stored in digital format and so on. We look at the 50-in LCD in the lounge room, pause for a second, take a look at the picture and think, well that was five grand well spent.
  • Wireless networks that build themselves
    Wireless sensors in embedded systems in devices from traffic lights to mobile phones, designed to create wireless communications networks automatically, could benefit a range of areas, including emergency management, security, helping vulnerable people to live independently, traffic control, warehouse management and environmental monitoring.
  • Taxis and buses measure wireless quality
    Can taxis and buses measure wireless network quality? According to Andrew Corporation yes, taxis and buses are important extensions of a wireless network operator's efforts to measure network performance and improve service levels.
