Technical advantages of wireless ad hoc networks

Wireless ad hoc network communication, with its flexible communication methods and powerful transmission capabilities, has the following characteristics:

A. Large-scale and rapid network construction and flexible networking

On the premise of ensuring power supply, it is not restricted by the deployment of supporting facilities such as computer rooms and optical fibers. There is no need to dig trenches, dig walls, or run pipes and wires. The construction investment is small, the difficulty is low, and the cycle is short. It can be deployed and installed flexibly in a variety of ways indoors and outdoors to achieve fast network construction without a computer room and at low cost. Centerless distributed networking supports point-to-point, point-to-many and many-to-many communications, and can build arbitrary topology networks such as chain, star, mesh, and hybrid dynamic.

B. Destruction-resistant and self-healing dynamic routing and multi-hop relay

Rapid movement, increase or decrease of equipment nodes, corresponding network topology updates in seconds, dynamic reconstruction of routes, real-time intelligent updates, and multi-hop relay transmission between nodes.

C. Support high-speed movement, high-bandwidth, and low-latency adaptive transmission that resists multipath fading.

D. Interconnection and cross-network integration

The all-IP design supports the transparent transmission of various types of data, interconnects with heterogeneous communication systems, and realizes the interactive integration of multi-network services.

E. Strong anti-interference with smart antenna, smart frequency selection, and autonomous frequency hopping

Time domain digital filtering and MIMO smart antenna effectively suppress out-of-band interference. At the same time, it supports intelligent frequency selection working mode. When the device is networked and the working frequency is interfered with, it can intelligently select a frequency point without interference for network transmission, effectively avoiding random interference, and supporting autonomous frequency hopping working mode, providing Any group of working channels within the working frequency band can jump synchronously at high speed across the entire network, effectively avoiding malicious interference. In addition, FEC forward error correction and ARQ error control transmission mechanisms are used to reduce the packet loss rate of data transmission and improve the effectiveness of data transmission.

F. Security encryption

Fully independent research and development, customized waveforms, algorithms and transmission protocols. Air interface transmission uses 64bits keys, which can dynamically generate scrambling sequences to achieve channel encryption. Supports DES56/AES128/AES256 source encryption to enhance security. Provides hardware encryption such as chips, TF cards and security machines.

G. Industrial design, professional manufacturing, high reliability of red and blue hot standby

The equipment adopts Swiss LEMO aviation plug interface, which has strong vibration resistance and strictly meets the anti-vibration operation requirements of motorized transportation. It has an IP66 protection level and a wide operating temperature range, which can meet the harsh outdoor all-weather working environment.

H. Easy operation and convenient operation and maintenance

Provide vent and maintenance. It has real-time monitoring, GIS map and other functions, and supports remote software upgrade/configuration/hot restart.

3. Point-to-point, point-to-many and many-to-many large-range, high-speed, and low-latency transmission of real-time data, high-definition video, and clear voice

Wireless ad hoc network radio is signifarious network ports, serial ports and Wi-Fi AP, mobile devices, computers or PADs, local or remote login terminal system software, operation managemicantly used in non-visual (NLOS) multipath fading environments, key communications of video/data/voice:

COFDM advantages:


Strong anti-interference: FDD is effectively against the multipath interference of signal waveform with the COFDM modulation. When the frequency selective fading occurs due to multipath transmission in the channel, only the subcarriers in the band depression and the signal carried by them are affected. The other subcarriers are not affected. Therefore, the overall bit error rate of the system is lower.


Anti-multipath fading: The COFDM Transceiver is effectively against the interference with the multi-carrier technique (COFDM). Compared to the single carrier, multi-carrier inherently resistant to time delay and has strong multipath capability. With joint coding of subcarriers & frequency diversity of the channel, the system’s performance is improved. Therefore, COFDM wireless system is suitable for multi-path environment and fading channel high-speed audio video data transmission.
