More choices for Land Mobile Radio users

  • IP-based solutions expand your LMR options for greater interoperability and expanded coverage.
  • Make sure that the LMR-ready solution you choose is optimized for network quality and user experience.

Land Mobile Radio (LMR) systems have long been the de-facto communication networks for voice services in multiple industries, including public safety, transportation, and utilities. With the availability of an IP-based interoperability solution from AT&T, you now have the opportunity to not only augment but also expand your coverage and ease network congestion with commercially available LTE networks.

What are the parameters of an expanded LMR network?

Start with preserving your existing LMR system and wireless network investments. Then evaluate short-term uses, such as offloading the LMR network with non-critical users to ease network congestion, while enabling these users to engage in important user group conversations. Next come longer-term goals, like focusing on migrating more users to a commercial LTE network to enable access to applications that use broadband-enabled wireless devices.

Keeping these needs in mind, when you’re ready to start this migration path, you need to pay close attention to not only the Push-to-Talk over Cellular (PoC) solution but also how the solution is optimized on the network to offer the best quality of service and experience.

When PoC solution vendors introduce an LMR-ready solution to you, you should ask three important questions to confirm readiness: Is their POC solution standards compliant? Is it based on mission-critical PTT functional architecture? And is it carrier-integrated with scalability, resilience, robustness, and 24/7 support?

Only those solutions that answer yes to each of these questions can deliver the service interoperability, scalability, security, performance optimization, and assurance necessary for business and mission-critical communications.

AT&T Enhanced Push-to-Talk delivers on all counts and also extends APIs that can be contextually integrated with proprietary and commercially available field services and workforce applications. It’s proven to be a reliable, scalable, and carrier-grade PoC solution that is fully optimized on AT&T commercial LTE networks and available on rugged mobile devices and tablets, with appropriate two-way radio accessories.

But keep in mind that not all PoC solutions are the same. Carrier network optimization is critical and must provide users with fully supported, secure operations.

What do you look for in an IP-based LMR interoperability solution?

Today’s IP standards have revolutionized the proprietary nature of LMR networks, while defining the standard interfaces needed for interoperable communication between components from different vendors.

This means that IP connectivity can now provide the seamless interoperability needed to take LMR augmentation to the next level – making it possible for you to seamlessly offload the LMR network, extend network coverage, and enhance features functionality. And you can do it all without adding new LMR sites, frequencies, or gateways, as you preserve existing investments.

Consider AT&T’s implementation of open-standard IP connectivity that’s designed to make dispatch and resource coordination easy and efficient. With it, dispatchers can conduct both group and one-to-one calls directly with push-to-talk users on cellular networks. Push-to-talk users can also communicate with talkgroups and other LMR networks for a level of connectivity only LMR users could previously access.

Whichever direction you’re headed, it’s clear you now have a better choice when it comes to LMR connections for your mobile workforce.
