DMR IP Site Connect
Powerful Wide-Area Radio Solutions
DMR IP Site Connect (often referred to as IP Multi-Site Connect) is a powerful digital networking solution designed to link geographically dispersed two-way radio users over standard Internet Protocol (IP) networks. By leveraging your existing Local Area Network (LAN), Wide Area Network (WAN), or the public internet, this technology connects multiple independent DMR Tier II repeaters into a unified, wide-area communication system.
This architecture effectively eliminates geographic barriers and severe structural dead zones, allowing teams located in separate corporate facilities, different cities, or massive multi-story buildings to communicate instantly. Deploying this solution maximizes your radio coverage without incurring heavy infrastructure costs or requiring complex IT overhauls. Your field units benefit from automatic roaming, transitioning seamlessly between overlapping repeater sites without ever needing to manually switch channels.

The Core of IP Multi-Site Connect Technology
Historically, connecting two distant radio towers required expensive leased phone lines or complex microwave links. IP Multi-Site Connect revolutionizes this by using the standard internet backbone already present in modern commercial buildings.
If your organization manages a manufacturing plant in North Carolina and a distribution hub in Texas, standard radio signals cannot bridge that gap. By connecting a digital repeater at each location to your corporate IP network, the voice data is instantly digitized, sent over the internet, and broadcasted out of the distant repeater. To the users holding the radios, it sounds exactly like they are standing in the same room.
Because it carries true digital DMR protocols, a connected IP network supports much more than just voice. It enables unified wide-area dispatching, group text messaging, live GPS tracking, and network-wide emergency alerts, making it the highly scalable choice for multi-campus environments, logistics hubs, and expanding enterprises.
5 Engineering Standards for DMR IP Site Connect Networks
When architecting a linked network for your enterprise, Teltra focuses on engineering metrics that guarantee stability, clarity, and ease of use for your frontline workers. We prioritize the following five technical standards for all wide-area deployments:
| Engineering Standard | Operational Benefit | Ideal Network Application |
| 1. Standard IP Integration | Utilizes existing LAN/WAN infrastructure, eliminating the need for leased telecom lines. | Multi-building corporate campuses and widespread school districts. |
| 2. Automatic Roaming | Radios seamlessly switch to the strongest repeater tower without manual channel changes. | Logistics drivers and mobile security patrolling massive properties. |
| 3. Unified Network Dispatch | Allows a single PC-based dispatcher to monitor and coordinate traffic across all linked sites. | Regional transport hubs and multi-state utility grids. |
| 4. Structural Dead Zone Elimination | Links multiple indoor and outdoor repeaters to fill coverage gaps caused by concrete and steel. | High-rise residential buildings, hospitals, and underground parking. |
| 5. Cross-Site Telemetry & Data | Transmits GPS coordinates, text messages, and emergency alerts across the entire wide-area network. | Multi-agency mutual aid and enterprise asset tracking. |
Custom Wide-Area Infrastructure Engineered by Teltra
Teltra provides comprehensive engineering support to optimize your wide-area communication system. We handle the complex IT integration required to ensure your radio network securely handshakes with your corporate firewalls without dropping voice packets.
Overcoming Structural Dead Zones
Not all IP linked networks are spread across the country. Teltra frequently uses DMR IP Site Connect to solve massive in-building coverage issues. For example, a sprawling hospital campus with thick lead-lined radiology departments and subterranean basements will naturally block radio signals. By strategically placing multiple repeaters throughout the facility and linking them via the hospital's LAN, we create an overlapping umbrella of coverage that completely eliminates indoor dead zones.
Connecting Dispersed Facilities
For growing businesses, maintaining separate, isolated communication systems at each branch creates operational silos. We engineer IP-linked systems that unify your entire operation. A production manager at your primary factory can use their portable radio to instantly hail the loading dock at a warehouse located 500 miles away, treating the entire organization as a single, cohesive talkgroup.
Seamless Automatic Roaming
The true power of IP Multi-Site Connect lies in its simplicity for the end-user. We program your portable and mobile radios with advanced automatic roaming protocols. As a user drives away from Facility A and approaches Facility B, the radio constantly evaluates the signal strength (RSSI) of both repeaters in the background. Once the signal from Facility B is stronger, the radio automatically "votes" and connects to the new tower. The user never has to touch a dial or realize they have switched sites.
DMR IP Site Connect: Frequently Asked Questions
What is DMR IP Site Connect?
DMR IP Site Connect is a digital radio networking feature that uses standard IP networks (like the internet or a corporate LAN) to link multiple DMR Tier II repeaters together. This bridges the physical distance between isolated radio networks, creating a single, unified communications system that spans cities, states, or sprawling corporate campuses.
Does IP Multi-Site Connect require expensive new infrastructure?
No. One of the greatest advantages of IP Multi-Site Connect is its cost-effectiveness. Instead of installing expensive microwave links or paying monthly fees for dedicated T1 telecom lines, the system leverages the broadband internet connections your business already pays for to transmit the radio data securely.
How does automatic roaming work on a wide-area communication system?
On a properly engineered wide-area communication system, radios are programmed with a "roam list" of all available repeater sites. As the radio user moves geographically, the device constantly measures the signal strength of nearby towers. When the current signal drops below a specific threshold, the radio automatically connects to the next strongest tower in milliseconds, ensuring uninterrupted voice coverage without manual intervention.
