• Private Call: One-to-one voice communication, suitable for private conversations.
• Group Call: Simultaneous multi-party conversation, suitable for team collaboration.
• All Call: Broadcast notification for issuing emergency instructions.
• Broadcast Call: Only the master unit speaks while all other devices receive, ensuring instructions are conveyed without error.

2.3.2 Channel Management and Encryption:

• Flexible Digital/Analog Channel Switching: Meets communication requirements across different frequency bands.
• AES 256-bit Voice and SMS Encryption: Ensures the security of communication content, preventing eavesdropping and data leakage.

2.3.3 Remote Control Functions:

• Remote Monitoring: Activates the device microphone via command to obtain real-time on-site audio.
• Remote Kill and Revive: In the event of device loss or theft, the device can be remotely killed to prevent misuse; it can be reactivated via remote command (Revive).

2.4 Short Message Communication

2.4.1 Flexible Short Message Functions:

• Individual, Group, and All Call SMS: Supports text transmission and reception, suitable for rapid notifications.
• IP Acknowledged SMS: Ensures successful message delivery, suitable for important information transmission.
• IP Unacknowledged SMS: No receipt required, suitable for bulk message sending.

2.4.2 Data Transparent Transmission and File Transfer:

• Small File Transfer: Small files such as images and text can be transmitted via short messages.
• Transparent Data Transparent Transmission: Supports transparent transmission of sensor data and control commands, meeting industrial control requirements.

2.5 Power Management and Energy Saving

2.5.1 Smart Battery Management:

• Low Battery Alarm: Automatically alerts at 30%, 20%, and 10% battery levels to prevent mission interruption.
• Automatic Sleep and Transmission Interruption Protection: Automatically enters sleep mode when idle to extend battery life; the Transmission Interruption Protection (TOT) function prevents prolonged channel occupation.

2.5.2 Efficient Power-Saving Design:

• Users can set sleep time (e.g., automatic sleep after 5 or 10 minutes of inactivity) to ensure optimized power management for long-duration missions.

2.6 Contact List Function

• The contact list registers communication parameters such as the frequency point of each terminal. When contact with another terminal is needed, this terminal will modify its own communication parameters to match, enabling temporary intercom communication. After the intercom session ends, or when the session times out, this terminal will restore its own parameters.

4. Application Scenarios

4.1 Application Scenario 1: Public Safety and Emergency Rescue

4.1.1 Scenario Description

In emergency response scenarios such as disaster rescue, police operations, and firefighting, traditional communication methods (e.g., cellular networks) often fail due to damaged base stations or network congestion. The IDM JQ380 Trunking Intercom Companion, by integrating RTK positioning, short message communication, and the PDT digital trunking system, ensures rapid information transmission and precise positioning during emergencies, providing robust support for public safety and rescue operations.

4.1.2 Application Case

(1). Solution: The rescue command center equips frontline rescue teams with the IDM JQ380 Trunking Intercom Companion. Through the device's RTK positioning system, the real-time locations of rescue personnel can be uploaded to the command center's dispatch platform. The device's group call and all-call functions enable the command center to conduct unified dispatch and issue instructions to multiple rescue teams.

(2). Outcomes:

• Real-time location tracking reduces the risk of rescue personnel getting lost.
• In areas without signal coverage, casualty information and supply requirements can be transmitted via short messages, improving rescue efficiency.
• The remote monitoring function helps the command center understand the on-site environment during critical moments and respond quickly.

4.2 Application Scenario 2: Self-Driving Tours and Outdoor Expeditions

4.2.1 Scenario Description

In self-driving tours, outdoor expeditions, and high-altitude trekking, traditional cellular signals are often insufficient due to remote locations, resulting in communication dead zones. Under these circumstances, ensuring inter-team communication and personnel safety is the top priority.

4.2.2 Application Case

(1). Background: Signal coverage is uneven along mountain self-driving routes, and communication among convoys is prone to interruption in alpine canyon areas.

(2). Solution: Equip the convoy with the IDM JQ380 Trunking Intercom Companion, enabling communication among convoy members via PDT trunking, while using RTK positioning to ensure real-time location sharing of convoy vehicles.

(3). Outcomes:

• Convoy members share road condition information through the group call function, avoiding traffic congestion.
• In emergencies (e.g., vehicle breakdowns), distress messages can be sent via short message communication.
• The positioning function enables rear support vehicles to quickly locate and provide assistance.

4.3 Application Scenario 3: Industrial Sites and Enterprise Internal Communications

4.3.1 Scenario Description

In industrial sites such as mines, power facilities, and oil drilling platforms, traditional communication methods (e.g., Wi-Fi and mobile networks) cannot meet requirements due to complex environments and long distances. Meanwhile, ensuring operational safety and effective dispatch is also critical.

4.3.2 Application Case

(1). Background: During underground mining operations at a certain mine, wireless signals deep in the mine shaft are restricted, creating communication dead zones that increase operational risks.

(2). Solution: Deploy the IDM JQ380 Trunking Intercom Companion within the mine, ensuring stable communication between underground and surface operations through PDT digital trunking and short message functions.

(3). Outcomes:

• The device's squelch function reduces ambient noise in the mine, improving voice clarity.
• Underground workers report safety hazards in real time via the intercom device, and the surface command center responds promptly.
• The positioning function ensures visualization of personnel locations within the mine, improving emergency rescue efficiency.

4.4 Application Scenario 4: National Defense and Border Security

4.4.1 Scenario Description

In scenarios such as national defense mobilization and border patrol, ensuring seamless and secure communication is of paramount importance. Particularly in remote border areas where traditional communication base stations have limited coverage, more stable and secure communication equipment is required.

4.4.2 Application Case

(1). Background: A certain border region features complex terrain, and patrol teams are required to conduct round-the-clock patrol missions in harsh environments where traditional communication means cannot provide coverage.

(2). Solution: Equip patrol teams with the IDM JQ380 Trunking Intercom Companion to ensure uninterrupted communication between patrol teams and the command center. Additionally, the RTK positioning system is utilized for real-time monitoring of patrol routes.

(3). Outcomes:

• The device's voice encryption and data encryption functions ensure the security of military information.
• Border anomalies can be reported via short messages, enabling rapid response.
• Position information is uploaded at scheduled intervals, allowing the command center to monitor the location and status of patrol teams in real time.
