COFDM Wireless IP Mesh Multi-hop WiFi MIMO Radio Network NLOS Communication




DS-MESH001HH COFDM IP MESH Radio combines with COFDM modulation, high efficiency channel coded and MESH networking protocol that realized network integration of video, data, audio, and GPS data with seamless transmission.


Unlike other wireless solutions, the IP MESH has self-managing ability. The COFDM IP MESH keeps adjusting itself when node working in moving condition, to select the best route for range extension and signal communication between each mesh node.
What’s more, the IP MESH also has self-healing features. When one of the node stops working, the rest of the nodes can communicate with each other directly or through one or more intermediate nodes.

With high flexibility in mesh topology, the data and video can be exchanged in poin-to-point, point-to-multipoint or multipoint-to-multipoint.


Suitable for mobile command vehicle, vehicle convoy or ship-to-ship communication, border surveillance, mining operations, remote oil and gas operations, mining operations etc.

Wireless ad hoc network products and application considerations
Wireless ad hoc network products can be divided into software radio platforms and WiFi Mesh, broadband and narrowband Mesh in terms of implementation technical system and performance indicators. Ad hoc network products based on software radio platforms, physical layer wireless transmission, give full play to more modern antenna technology, coding technology, modulation and demodulation technology and anti-interference technology to achieve broadband, long-distance and stable and reliable transmission; MAC/LLC Data link layer, flexible access mechanism, resource management, and error control, flow control, power control, and network transmission layer, optimized routing design, neighborhood maintenance, backoff window, and adaptive transmission, reaching unprecedented scale Scale, large capacity, efficient and secure networking flexibility. WiFi Mesh based on various chips such as Qualcomm has low cost, small size and low power consumption.

A. Working environment, communication distance

The flexible networking and powerful transmission of wireless ad hoc networks are more suitable for information transmission in complex terrain environments such as forests and lakes, barren mountains and wilderness, dense buildings, tunnels, culverts, and underground spaces.

The transmission distance of wireless communication first depends on the propagation characteristics of electromagnetic waves in the working frequency band, including sky waves, ground waves, space waves, as well as direct radiation, reflection, diffraction and scattering caused by different transmission media, as well as space-time changes caused by rapid movement, so that The propagation of radio waves is very complex. Path loss, shadow fading, multipath effect and Doppler effect lead to large-scale slow fading and small-scale fast fading of the received signal. Secondly, it is closely related to the transmission technology used in the product. OFDM, single-carrier frequency domain equalization, MIMO, and collaborative communication can greatly improve the broadband transmission distance in complex environments.

B. Provide services and transmission rates

Dedicated wireless communication equipment can provide intercom voice, various measurement and control, location and other asynchronous data streams as well as IP streams and high-definition video. It can perform broadcast, multicast and directional propagation. The transmission rate of a single point-to-point link can range from several hundred K , several megabytes to hundreds of megabytes.

C. Network scale, multiple jumps

In theory, wireless ad hoc networks can support unlimited node scale. In practice, it is limited by link rate bandwidth and transmission information, especially public information such as nodes, links, routes, protocols, etc. As the size of the node network increases, , limit the transmission of business information, and the actual number of nodes and network scale.

Dynamic routing and multi-hop relay are the greater advantages of wireless ad hoc networks. Theoretically, the number of jumps is unlimited. The wireless ad hoc network node radio transmits and receives, works with time division duplex TDD, and the relay function of the node radio is performed through store forward repeater. In this way, each time a data packet passes through a relay, a link needs to be added. The transmission time, that is to say, the same data packet is transferred once, which increases the transmission time. As a result, the actual transmission rate after multiple transfers, that is, after multiple hops, will decrease. Through frequency division multiplexing and spatial multiplexing, it can be achieved that after three hops, the transmission rate will no longer drop.

D. Transmission delay, video delay

Communication equipment is used to transmit information data, from interface input, to encoding, modulation, transmission, to reception, demodulation, decoding, and interface output. The entire processing and transmission time ranges from one millisecond to dozens of milliseconds, depending on, The hardware platform and transmission protocol, wireless ad hoc network radio, are about 10 milliseconds.

Video transmission, from camera (tens of milliseconds), video encoding (tens of milliseconds), to transmission and reception of network port communication equipment (ten milliseconds), to video decoding (tens of milliseconds), to the display (tens of milliseconds), The end-to-end delay of the entire process is between one hundred milliseconds and three to five hundred milliseconds.

E. Anti-interference and confidential communication

Radio communication, which transmits information through electromagnetic waves, interference and anti-interference are a pair of spears and shields. The use of band-pass filters to suppress out-of-band clutter and harmonics is a common anti-interference measure for broadband communications. MimoMesh broadband self-organizing network radio uses time-domain digital filtering and MIMO smart antennas to 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 supports 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, the radio station uses transmission mechanisms such as FEC forward error correction and ARQ error control to reduce the packet loss rate of data transmission and improve the effectiveness of data transmission.

Eliminate illegal joining by setting parameters such as working frequency, channel bandwidth, system code, communication distance, and working mode. MimoMesh broadband self-organizing network radio station is fully independently developed with 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. In addition, the radio station provides hardware encryption such as chips, TF cards and security machines.
