2.3.1 Rich Communication Modes

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

2.3.2 Channel Management and Encryption

• Flexible switching between digital/analog channels: Meets communication requirements across different frequency bands.
• AES 256-bit voice and SMS encryption: Ensures communication content security, 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 case of device loss or theft, the device can be remotely disabled (Kill) to prevent misuse; it can be reactivated (Revive) via remote command.

2.4 Short Message Communication

2.4.1 Flexible Short Message Functions

• Private call, group call, and all call SMS: Supports text sending and receiving, suitable for quick 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: Supports transmission of small files such as images and text via short messages.
• Transparent data 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 level to prevent task 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

• User-configurable sleep time (e.g., automatic sleep after 5 or 10 minutes of inactivity), ensuring optimized power management for long-duration missions.

2.6 Contact List Function

• The contact list registers communication parameters such as frequency points for each terminal. When contact with another party is needed, the terminal modifies its own communication parameters to match and establishes temporary intercom communication. After the call ends or when the session times out, the terminal restores its original 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 radio companion combines RTK positioning, short message communication, and the PDT digital trunking system to ensure rapid information transmission and precise positioning in emergency situations, providing strong 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 radio 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 perform unified dispatch of multiple rescue teams and issue instructions.

(2). Results:

uReal-time location tracking reduces the risk of rescue personnel getting lost.

uIn areas without signal coverage, short messages are used to transmit casualty information and supply requirements, improving rescue efficiency.

uThe 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. In these situations, ensuring communication among team members and the safety of personnel is the top priority.

4.2.2 Application Case

(1). Background: During self-driving trips through mountainous areas, signal coverage is uneven along the route, and communication among convoy vehicles is prone to interruption in high-mountain and canyon terrain.

(2). Solution: Equip the convoy with the IDM JQ380 trunking intercom companion, enabling communication among convoy members via PDT intercom, while RTK positioning ensures real-time location sharing of convoy vehicles.

(3). Results:

uConvoy members share road condition information through the group call function, avoiding traffic congestion.

uIn emergency situations (e.g., vehicle breakdowns), distress messages can be sent via short data messaging.

uThe positioning function enables rear support vehicles to quickly locate and assist.

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 limited, creating communication blind zones that increase operational risks.

(2). Solution: Deploy the IDM JQ380 trunking intercom companion inside the mine, using PDT digital intercom and short data messaging to ensure stable communication between underground and surface operations.

(3). Results:

uThe device's squelch function reduces ambient noise in the mine, improving voice clarity.

uUnderground workers report safety hazards in real time via the intercom device, and the surface command center responds promptly.

uThe positioning function ensures visual tracking 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 critical. Especially in remote border areas where traditional communication base stations cannot provide coverage, more stable and confidential communication equipment is required.

4.4.2 Application Case

(1). Background: In a border region with complex terrain, patrol teams must conduct round-the-clock patrol missions under harsh conditions, where traditional communication methods cannot provide coverage.

(2). Solution: Equip patrol teams with the IDM JQ380 trunking intercom companion to ensure smooth communication between patrol teams and the command center. Additionally, the RTK positioning system is used for real-time monitoring of patrol routes.

(3). Results:

uThe device's voice encryption and data encryption functions ensure the security of military information.

uBorder anomalies are reported via short data messaging, enabling rapid response.
