Product introduction
Sf-5000ms series products are enterprise and operator class 802.11n outdoor wireless base stations, which provide wireless system providers for PTP point-to-point / PTMP point to multipoint / hotzone wireless coverage hot area and other systems. The product adopts 2.4GHz and 5GHz dual frequency multi module design, single wireless module can achieve 320mbps transmission rate, bandwidth can reach 160mbps; multi wireless module can add 640mbps transmission rate, bandwidth can reach 320mbps, easily solve the problem of insufficient application of long-distance transmission bandwidth. It can be used in campus wireless outdoor coverage network, wireless monitoring remote transmission, plant to plant data transmission backbone, urban wireless Internet coverage and large area wireless monitoring image transmission collection Application system.
The sf-5000ms series offers three product function categories:

1. Multi point continuous relay hopping, low loss backbone bandwidth function:

The transmission bandwidth is no longer reduced after the fifth hop, which can be maintained above 120mbps bandwidth. At the same time, it has the characteristics of low delay within 10ms after 10 hops. The sf-5000ms-03h has three wireless modules, so it can construct three continuous relay platform hopping backbones to provide different directions of transmission and greater bandwidth convergence.

2. Continuous relay platform hopping + mesh multi-path self-healing network function:

According to the requirement of wireless Internet service or wide range wireless monitoring transmission, the solution product of WiFi MIMO multi-path mesh wireless network is proposed. It mainly uses mesh network transmission function and the characteristics of automatic selection or repair transmission link and automatic networking to solve the link failure problem of general network system.

3. Continuous relay platform hopping + mesh multi-path self-healing network + supporting high-speed mobile transmission function

It is specially designed for operators who need a wide range of wireless high-speed mobile transmission applications, such as urban road or expressway wireless high-speed mobile monitoring transmission, railway high-speed mobile data transmission, underground railway high-speed mobile data transmission, and even high-speed mobile data transmission of high-speed railway. Through the mesh network characteristics of mesh network system, the large bandwidth characteristics of multi-point platform hopping backbone, and the specially designed mesh client function features, the high-speed mobile data can be quickly and automatically selected path transmission on the mesh network of mesh network system.

Sf-5000ms has the following advantages:

1. Flexible selection of wireless backbone erection mode

Sf-5000ms series products integrate multiple wireless module interfaces and import core multiple data exchange technology. Each wireless interface can be set separately to meet different wireless transmission purposes. The fast data exchange technology between multiple wireless module interfaces can provide stable large bandwidth backbone and smooth packet transmission with low delay even though the data stream passing through several wireless relay hopping platforms or multiple wireless module interfaces.

2. Efficient wireless backbone design

With the introduction of a new generation of 802.11n MIMO technology, each wireless module interface can provide up to 300mbps under 40MHz spread spectrum setting It can further improve the efficiency of packet transmission and the total bandwidth of backbone transmission to achieve 900mbps wireless backbone transmission rate and 320mbps actual bandwidth of wired bandwidth.

3. Secure and flexible client connection management

Flexible QoS (quality of service) settings provide management users with wireless bandwidth connection management. Sf-5000ms series perfectly combines the central radius server and data encryption technology to provide secure wireless connection service for each wireless client device.

4. With mesh network function (optional software function)

Under the requirement of large-scale network backbone system erection, mesh network function is optional to provide network transmission, with the following special operation mechanism:

A. with OSI (open system interconnection reference model) La

B. automatic search for the best transmission path mechanism

C. mechanism of automatic disconnection to find and restore online path

D. automatic network traffic balancing mechanism

E. automatically update node information of mesh network system

F. automatic scanning, channel selection and automatic online

G. automatically update system settings through gateway or server

H. automatically organize cloud network

I. support fast automatic path transmission

J. support signal and transmission rate logic operation high speed roaming transmission

K. support large bandwidth mesh network transmission

L. support multiple gateway exit backup functions

With mesh multi-path hi mobile high-speed mobile network transmission function (optional software function)

Through the multi-point platform hopping relay and mesh network functions, combined with hi mobile high-speed mobile operation settings, the mesh hi mobile high-speed mobile transmission network can be constructed, providing a mobile wireless transmission bandwidth of 200 km / s speed of 100 Mbps, so as to provide the application requirements of high-speed mobile transmission.

Mesh mobility network has the following online features:

1. Mesh gateway: the highest and first layer of the whole mesh network system, which is responsible for the registration, login and data update management of the equipment of the overall mesh system, and acts as the final collection point of the transmission data of all systems and the gateway exit of the external network.

In addition, it can be used as the backbone network of the mesh network The transmission outlet of network receiving node belongs to the second layer of the whole mesh network system.

3. Mesh access point (mesh multi-path network receiving node): it can connect the upper layer "mesh network backbone node" and the upper layer "mesh network gateway exit". The same "mesh network receiving node" can communicate with each other and "connect with each other to form a mesh network receiving backbone network". The most important operation function is to be responsible for the "mesh network" of the next layer The wireless online service of "network client" and uploading to the upper layer transmission outlet belong to the third layer of the whole mesh network system.

4. Mobility station / client (mesh network mobile platform): it is mainly used in high-speed mobile customer transmission terminal. It will carry out wireless online data transmission and roaming in mesh according to the network system information of "mesh network gateway exit" and the best path of "mesh network backbone node" and "mesh network receiving node" In the multi-path mesh network system.
