شبكة الضيقة الضيقة الشبكة المخصصة الشبكة الداخلية

Advanced self-developed technologies

1. multi-level and multi-hop relaying technology
2. intra-frequency simulcasting networking technology
3. signal overlapping and merging technology
4. Supports off-network intercom and single-unit relay (intercom terminal can be used as a relay) للاتصال الآمن.
5. Features digital trunking functions such as group call, مكالمة البث, and private call.
6. Equipped with built-in GPS and Beidou positioning modules, providing high-speed positioning within 4 ثواني.

The simul Hoc digital walkie-talkie constructs a centerless ad hoc communication network, which’s coverage reaches 2-3 times that of traditional walkie-talkies. في نفس الوقت, it provides clearer voice calls and member positioning, making communication more flexible.

Intelligent Signal Transmission || Smart Positioning Sharing || Intelligent Condition Monitoring

Narrowband Ad Hoc network technology does not require routing, and multiple nodes automatically determine whether to initiate forwarding by receiving signal quality and field strength. This elevates the relay from a network layer multi hop single point relay to a physical layer multi hop multi point relay, elevating the relay from a linear relay to a mesh relay. By intelligently relaying the received signal quality and field strength automatic judgment at the physical layer, and merging multiple signal points, the coverage effect and transmission distance are greatly improved.

ميزة

• انتقال المدى:The receiver sensitivity is as low as -128dBm, and the city’s communication single-hop transmission distance is >5كم, which far exceeds the transmission distance of 5W transmission power of well-known brand intercoms.

  

• Instantly connects in just 10 milliseconds with no time synchronization. With support for up to 8-hop centerless mesh networking, it extends the communication range up to eight times farther. Even handheld units can automatically form a network without relying on a base station.

  

• Dynamically changing network topology:This technology is based on ultra-fast synchronization and advanced signal processing, enabling communication establishment and dynamic network topology convergence within just 1 ميلي ثانية واحدة.

  

• Real-time location sharing: Multi-mode accurate positioning, real-time sharing of locations, and the member location is clear at a glance.
• Digital noise reduction: With the new digital noise reduction chip, clear and loud speech can be presented even in a noisy environment.
• Encrypted communication: The independent communication mechanism, with AES256 encryption and tens of thousands of block codes, which can achieve super-encrypted communication.
• IP67 protection class: Support IP67 protection level, can be soaked in one meter deep water for 30 minutes without affecting the normal use of the product.
• موثوق, Sturdy and durable: The quality is strictly in line with the US military standard MIL-STD-810 C/D/E/F/G, which can perform excellent performance in a bad working environment.
• Voice communication: مكالمة واحدة, team call, مكالمة جماعية
• Location service: Built-in multi-mode high-precision positioning chip
• Member location view: Real-time view of member position and distance information.
• One Key for Help: In case of emergency, one key enters the help state, sends help information and plays a high-decibel alarm.
• Voice recording: Large capacity ROM, which can store up to 3000 intercom records.
