Product Description

250KHz Voice and IP Data Transmitter NB Ad Hoc Networking Device



1. Description of NB Ad Hoc Networking Device


This technical introduces the technical parameters and related interface descriptions of ST99020V2-1W2T2R-NB-Mesh narrowband Ad Hoc network core communication products, matching antennas and other major equipment.


The system is composed of self-developed mature hardware modules and stable software platforms, hardware modules including core communication modules, audio and video editing modules, and RF power amplifier modules.The core communication module of Ad Hoc network adopts software radio (SDR) architecture, which mainly implements physical layer (PHY), media access layer (MAC), link protocol and Ad Hoc network protocol etc.The core communication module is equipped with running memory RAM (8Gb), storage ROM (4Gb), built-in Micro-SD card holder, support Bluetooth Wi-Fi data transmission, support USB, LAN and asynchronous serial port interface, PTT earphone;Connect the audio and video coding module through the USB interface to transmit high-definition H.265 audio and video, equipped with the module connection status two-color indicator and signal quality three-color indicator interface, and support external RS-232 interface GPS Beidou module.



2. Specification of NB Ad Hoc Networking Device


Support business Voice, IP data, location information, serial port data
Business capabilities Voice 4.6kbps
IP Data Support unicast, multicast, broadcast, up to 520kbps
location information Broadcast all over the network
serial port data Support point-to-point bidirectional, point-to-multipoint unidirectional
Carrier bandwidth 250KHz,500KHz,1MHz
Service rate

20~140kbps@250kHz bandwidth

30~280kbps@500kHz bandwidth

70~580kbps@1MHz bandwidth

Modulation mode QPSK/16QAM/64QAM/256QAM/1024QAM(Adaptive)
Receive sensitivity ≤-116dBm(@250kHz,1.2kbps Voice)
Networking capabilities A single subnet can support at least 250 nodes
Intelligent frequency selection Support (frequency selection)
Multi-hop capability Voice 6 hops
Data business 6 hops
Frequency hopping Frequency hopping rate >1000 hop/s(Optional)
Frequency hopping points Max 256(Optional)

In frequency hopping mode, when 30% of the frequency points are interfered with, network communication can still be guaranteed and data service transmission can be ensured (the rate will decrease);

In other modes, when there is a 30% probability of sudden interference or other reasons causing transmission interruption, network communication can still be guaranteed to ensure data service transmission (the rate will decrease).

Encryption capabilities DES / AES128 / AES256(Optional)
Movement speed L-band, the maximum support node relative movement speed is not less than Mach 2
Multi-antenna capability Supports dual-antenna diversity,2x2 MIMO
