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. 同时, 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.
特征
- 传输范围:The receiver sensitivity is as low as -128dBm, and the city’s communication single-hop transmission distance is >5公里, which far exceeds the transmission distance of 5W transmission power of well-known brand intercoms.

mesh narrow band ad hoc network intercom radio walkie-talkie transmission range - 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.

Instantly connects in just 10 milliseconds and up to 8-hop centerless mesh networking - 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 毫秒.

Dynamically changing network topology - 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.
- 可靠的, 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: 单次通话, team call, 群组通话
- 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.

Narrowband mesh radio Vcan2132



iVcan.com –
I’ve been using this mesh intercom radio for several weeks, and it has completely changed the way our team communicates in the field. The coverage is much better than traditional walkie-talkies, thanks to the automatic multi-hop relay function, and the voice quality is impressively clear even in noisy environments. The real-time positioning feature is especially helpful because we can always see where our teammates are, which improves both safety and efficiency. I also appreciate the rugged design—it feels solid, and the IP67 waterproof rating gives us confidence in harsh conditions. 全面的, this device delivers reliable, 安全的, and intelligent communication that truly supports mission-critical operations.
