    • Modernising Your TETRA System as Part of a Long Term Sustainment Plan Author: Ricardo Gonzalez

      Published Mar 29 2018, 2:35 PM by Paul Jeffs

      As an operator of a public safety private mobile radio system, you face a complex set of challenges. How will you keep pace with rapid technological change? How can you profitably grow your network’s user base? What about cyber security? In truth, there are many more questions to which operators are seeking answers.

      So how can public safety PMR operators ensure that their radio system reliably and securely supports the mission-critical operations of users, while addressing their evolving requirements? Modernisation is key to addressing these challenges.

      Why you should invest in modernising your PMR network
      What are the risks of not doing anything? Failure to invest in the PMR network infrastructure will introduce a number of risks
            - Increased risk of system downtime due to aging hardware
            - Vulnerability to cyber attacks
            - Rising support costs due to obsolescence
            - Increased unpredictability of network maintenance costs
            - Inability to add new services and functionality required by users

      The need to address these risks and increase service flexibility has led to a growing number of PMR operators investing in network modernisation. For example, concerns about cyber crime and the need to implement new functionality were key drivers of City of Cape Town’s decision to modernise its TETRA public safety network. Following the upgrade to the TETRA system, City of Cape Town realised improvements in cyber security through enhanced encryption support and also greater flexibility in adding new features and additional capacity to the network. Read about City of Cape Town’s network modernisation here.

      To be effective, network modernisation must be part of a long term network sustainment plan that includes:
            - Network updates covering both hardware and software
            - Security updates
            - 24 x 7 x 365 technical support
            - Fast turnaround times for network hardware repairs

      Enhancing your PMR service through broadband integration
      Modernisation is not just about network sustainability – it’s also about supporting the evolving operational needs of users. Increasingly, broadband data services are being demanded by public safety organisations to enable increased in-field productivity, improved situational awareness and reduced operational costs. Additionally, broadband push-to-talk technology is allowing public safety organisations to extend the reach of their networks by leveraging the wide area coverage of commercial mobile networks.

      But, a concern for the public safety community is whether mission-critical voice and data services delivered over broadband networks can match the performance and functionality of established PMR systems such as TETRA and APCO Project 25. With the ongoing standardisation work within 3GPP to introduce mission-critical functionality, the prevailing view is that PMR networks and 4G and 5G systems will coexist for many years in order to get the best of both worlds.

      The good news is that PMR operators are uniquely positioned to address public safety needs and to offer a differentiated service. For example, PMR operators can use their existing Key Management Facility for the management and distribution of encryption keys to both radio and broadband users. This can be achieved today using Motorola Solutions LTE handheld devices equipped with the μCryptr hardware security module.

      Modern PMR systems such as DIMETRA X Core provide seamless, wireline interfaces with broadband systems. Integration of broadband services with PMR unlocks value and creates a platform for delivering truly differentiated services. For example, by integrating broadband PTT technology with their networks, public safety PMR operators can target a new segment of non-radio users that require talkgroup interoperability from their smartphone devices. The addition of such services creates revenue generation opportunities, providing a vital funding source for ongoing network investments in support of the long term technology sustainment plan.

      Forward-thinking PMR operators have already started adopting this self sustaining approach to network modernisation. For example, Spain’s Telecom Castilla-La Mancha recently transitioned their legacy TETRA system to the DIMETRA X Core platform - read the press release about it here. Integrated with the TETRA system was the WAVE interoperability solution, which enabled Telecom CLM to extend PTT communication across multiple platforms (radio, broadband networks, computers, smartphones) allowing users on different networks to be connected.

      Network Modernisation

      To unlock the full potential of your PMR system, it is vital that you work with the right technology partner. It is important that your technology partner can support you for the long term with the right level of service, technology expertise and experience in deploying public safety systems.

    • Ensuring Communications Uptime Author: Graeme Casey

      Published Mar 16 2018, 12:06 PM by Paul Jeffs

      A seamless, reliable network is essential to business- and mission-critical communications. From public safety and the military to transportation and logistics, organisations around the world rely on land mobile radio (LMR) systems as their go-to communications network.

      Since the 1930s and the early days of simple analogue two-way radios, LMR technology has undergone a massive transformation. Today’s LMR systems are software-defined and IP-based to meet users’ evolving need. And like all IT-based systems, whether shared or used by a single entity, they are not immune to cyberattacks.

      As a result, how they are maintained and supported requires a new breed of resources and expertise. System operators must be knowledgeable not only about the equipment but also about the IP- and software-centric network components to ensure communication is secure and available 24x7x365.

      How you manage your LMR system is vital to maximising uptime and limiting disruptions. Around the world, users are tackling this challenge in a variety of ways—from regular system updates and continuous network monitoring to proactive cybersecurity strategies and system performance trends and analysis.

      To gain a clearer picture of the measures that system operators are applying to their networks, Motorola Solutions is conducting an LMR system management survey.

      Our research report will provide insights into several compelling areas:

      • Support and maintenance services that your peers are using to support their LMR systems
      • Cybersecurity measures being taken to address and respond to threats
      • Best practices for minimising network downtime and improving system performance
      • Future system management priorities

      LMR systems operators and customers are invited to share their experiences and insights in our inaugural survey. The results will be used to help stakeholders and individuals responsible for ensuring system uptime improve their performance by learning from one another and gaining insights into the best ways to tackle the challenges of this complex communications environment.

      For every survey completed, Motorola Solutions will donate $5 USD to the International Federation of Red Cross and Red Crescent Societies (IFRC) or International Centre for Missing and Exploited Children (ICMEC). (Total donations will be capped at $2,500 USD.). Once our study is complete, we will be happy to share the results with you.
