DMR Tier II Conventional

DMR Tier II repeater sites enhance coverage, signal quality, and group calling capacity using DMR standard-compliant radios with FCC licensing. Repeaters receive low-power radio signals and retransmit them at higher power, expanding the communication range for businesses and industries needing efficient, wide-area connectivity. A DMR Tier II system includes a repeater, antenna system, and dispatch console for centralized voice calls, GPS tracking, messaging, and voice recording. While coverage is limited to a single site, Alpha Prime Communications ensures seamless integration for optimized communication networks.

DMR IP Site Connect

IP Site Connect links multiple DMR Tier II repeater sites over an IP network, creating a more extensive, seamless radio communication system. This solution extends coverage across distant locations, enabling real-time, instant communication between remote teams without additional infrastructure. With a simple license upgrade to a DMR Tier II repeater and IP network connectivity, organizations can easily migrate to a wider-area network while maintaining ease of use and reliable performance.

While IP Site Connect expands coverage, it does not increase calling capacity, making it an ideal solution for businesses needing broader communication reach without upgrading to a trunked system. Alpha Prime Communications delivers customized IP Site Connect solutions for seamless, multi-site communication.

DMR XPT Trunking

Hytera Extended Pseudo Trunk (XPT) enhances DMR Tier II repeater sites by dynamically managing talk channels across multiple repeaters, significantly increasing group calling capacity. Unlike traditional trunking systems, XPT achieves this without requiring a centralized controller, making it a cost-effective alternative for businesses needing greater communication efficiency. XPT can be deployed at a single repeater site or extended over an IP network to connect multiple XPT sites for wide-area communication.

Organizations can scale their radio network with minimal investment by adding a Layer 2 switch and an XPT repeater license. While XPT maximizes group call capacity, it is not ideal for high-volume individual radio-to-radio calls or operations requiring comprehensive access control.

At Alpha Prime Communications, we provide customized Hytera XPT solutions that expand communication capacity while maintaining seamless, efficient connectivity for large teams and multi-site operations.

DMR Tier III Trunking

DMR Tier III Trunking is an advanced, IP-based digital trunking system designed for large organizations with complex communication needs. It provides high-capacity individual and group calling, dispatching, and centralized radio management across broad geographic areas, making it the premier choice for mission-critical operations. By optimizing voice and data traffic through limited frequencies, Tier III maximizes efficiency for large user groups.

The system relies on repeater technology and a dedicated control channel managed by a Mobile Switching Office (MSO), Base Station Controller Units (BSCU), multiple repeaters, and a wide-area network for seamless communication. The architecture consists of three layers—application, network, and radio terminal—ensuring reliable, scalable performance.

DMR Tier III supports SMR (Specialized Mobile Radio) systems for commercial and public safety networks, providing secure, high-reliability communications for thousands of users. Alpha Prime Communications delivers custom DMR Tier III solutions that enable efficient, large-scale radio communication for organizations requiring secure, high-performance connectivity.
