Stolz Telecom Launches Sentinel Push-to-Talk, a Global LTE/5G Communications Platform for Modern Teams

Stolz Telecom, a 100 percent employee-owned company delivering industry-leading two-way radio systems, vehicle upfitting, and enterprise communication solutions across the US and the Caribbean, today announced the launch of Sentinel Push-to-Talk, a global LTE/5G push-to-talk communications platform designed to help organizations stay connected across cities, countries, and international operations without the limitations of traditional radio coverage.

Sentinel Push-to-Talk provides instant voice communication over LTE, 5G, and Wi-Fi networks, allowing teams to communicate across local, regional, national, and global service areas. The platform supports handheld push-to-talk radios, vehicle-mounted devices, mobile app users, GPS tracking, indoor location tracking, dispatcher tools, emergency features, flexible talk group management, and multi-carrier SIM connectivity for improved coverage and roaming flexibility.

“Sentinel Push-to-Talk was created to give organizations a reliable, easy-to-use communications solution that works wherever their teams operate,” said Robert Stolz of Stolz Telecom. “Whether it is a public safety agency, school district, security team, transportation company, utility, or global enterprise, Sentinel helps teams communicate quickly, coordinate more efficiently, and improve visibility in the field.”

A key advantage of Sentinel Push-to-Talk is its multi-carrier SIM option, which helps devices connect across supported carrier networks instead of relying on a single provider. This gives organizations greater flexibility for mobile teams operating across different regions, job sites, campuses, rural areas, urban environments, and international markets. For customers with users who travel between coverage areas, the multi-carrier SIM can help reduce connectivity gaps and simplify deployment by supporting broader network access without requiring separate SIMs for each carrier.

Unlike traditional land mobile radio systems that depend on local tower coverage, Sentinel Push-to-Talk operates over broadband networks, making it ideal for organizations that need wide-area communication, multi-location coordination, and scalable deployment options. Users can communicate from dedicated push-to-talk radios, smartphones, tablets, dispatch consoles, and compatible mobile devices.

Key capabilities of Sentinel Push-to-Talk include: 

• Instant one-to-one and group push-to-talk communication
• Global LTE, 5G, and Wi-Fi connectivity
• Multi-carrier SIM options for broader supported network access
• Flexible roaming support for mobile and international users
• Rugged handheld and mobile radio options
• Smartphone app access for flexible users
• GPS location tracking and fleet visibility
• Indoor location tracking for facilities, campuses, and large buildings
• Web-based dispatch console options
• Emergency alert and priority communication features
• Talk group management for departments, teams, job sites, and regions
• Scalable plans for small teams, large organizations, and international operations
   

Sentinel Push-to-Talk is backed by Stolz Telecom’s experience in mission-critical communications, radio systems, dispatch solutions, public safety technology, and field service support. The platform gives customers a modern communications option that can complement existing radio systems or serve as a standalone solution for organizations moving toward broadband-based push-to-talk.

Sentinel Push-to-Talk is available now for organizations seeking reliable, wide-area group communication with fast deployment, flexible device options, and multi-carrier connectivity.
