When public-safety LTE systems initially were proposed, some industry observers projected that broadband push-to-talk (PTT) solutions would replace land-mobile-radio (LMR) voice communications—in fact, United Kingdom officials planned on this happening by 2020. Such replacements have occurred, but they have been the exception. However, broadband PTT certainly has had an impact on the critical-communications market, supplementing LMR systems with expanded coverage and resiliency when interoperable with LTE-based offerings.

Key Takeaways:
Listen to people who have deployed real-world systems to learn how they are leveraging broadband PTT today.
Discuss the pros and cons of various broadband PTT offerings.
Examine the never-ending challenges associated with delivery interoperability between LMR and LTE while also ensuring that communications are secure, reliable and resilient.
