Comprehensive Comparison Between Wireless Mesh Network and other wireless network technologies

The Development of China's wireless mesh network is still very rapid, so I have studied the comprehensive comparison between the Wireless Mesh Network and other access network technologies. I would like to share with you here, I hope it will be useful to you. Wi-Fi is based on the IEEE802.11x standard technology. Currently, Wi-Fi includes IEEE802.11b, 802.11a, and 802.11g. Wi-Fi transmission uses low-power radio signals with poor penetration capability and cannot pass through metal, water, or other materials with high density. Generally, in a typical home or office, the Wi-Fi network transmission distance is about 25 to 50 meters. In an open outdoor environment, the Wi-Fi network transmission distance is only about 300 meters. Wi-Fi networks are characterized by high bandwidth, low communication range, and no mobility, but low prices. Therefore, they are mainly used for small-range wireless communication, it is defined as a wireless LAN. At present, the Wi-Fi network rapidly develops to crowded places or buildings, such as coffee shops, hotels, airport waiting halls, office buildings, and other places for users to access the Internet.

A wireless Mesh network is a new network structure based on multi-hop routing and peer-to-peer network technology. It features mobile broadband and can be dynamically expanded, automatic networking, management, automatic repair, and self-balancing. Compared with Wi-Fi, wireless Mesh greatly improves networking, transmission distance, and mobility, especially its compatibility with Wi-Fi, therefore, wireless Mesh networks can greatly help increase the transmission distance and mobility of Wi-Fi and expand Wi-Fi applications. At the same time, the popularization and application of terminals will bring benefits to the rapid promotion of wireless Mesh. Therefore, Wi-Fi and wireless Mesh networks can complement and integrate with each other.

Wireless Mesh Network Vs3G

As we all know, 3G has been brewing for a long time, and get the support and support of the world-famous communication companies, we also have TD-SCDMA proprietary technology in China, can be said to all the views. There is no doubt that 3G will certainly come, but it is only a matter of time. However, due to the enhanced operation of 2G and WLAN, the service life of 2G is prolonged, coupled with the emergence of Wireless ip man, as well as 3G standards and technical problems, 3G is in a very passive situation. So far, digital mobile phones have done well in some basic applications, such as voice communication, short messages, simple news services, and stock market quotations. The next step of mobile communication is to achieve direct video communication between mobile phones. However, the actual 3G data transmission rate is not ideal. The huge license fees and technical and terminal problems make the 3G development a long way to go. operators need to invest a lot of money and manpower to build and improve, these factors will bring huge challenges to the development of 3G.

The wireless Mesh network also has the characteristics of mobile and broadband, which is similar to the services provided by 3G. However, their positioning is different. 3G is located in the WAN. Like 2G and 2G, 3G will continue to serve the public's mobile communication. 3G development must rely on large-scale network deployment, which takes a long time. Wireless Mesh is based on IP addresses and is located in the Metropolitan Area Network. It is flexible in networking and can be used in a small range first, and then gradually developed. It is more suitable for private network applications in various vertical industries. It entered the market before 3G, and it also has strong compatibility, so that it will be compatible with 3G in the future, to solve the problem of 3G terminal access. "Moving towards IP" and "moving towards IP" are the development trend of communication. I believe there will be great possibilities for the combination of 3G and Mesh in the future communication market.

VsWiMAX

WiMAX is a promising technology in the current market. It is located in the wireless ip man, including 802.16a and 802.16e. The 802.16a standard has been formulated. It only supports line of sight transmission, fixed point access, and point-to-point or point-to-point networking. The 802.16e standard is still in the development stage, it supports non-line-of-sight transmission and has certain mobility. Currently, mature commercial WiMAX products have not been launched. It is very interesting that Mesh has commercial products. Standards have just been set up, while WiMAX has standards and there are no commercial products. From a market perspective, although both wireless Mesh and 802.16a are man applications, there will be no competition. Wireless Mesh is a mobile man, and its goal is to provide mobile broadband services for individuals in the private network; 802.11a provides point-to-point or point-to-point fixed access. The 802.16e product (with mobile performance added) may compete with the wireless mesh network. However, there are still some uncertain factors because the standard has not yet come out.

In general, in terms of market space occupation, the wireless mesh network has already entered the market before WiMAX and 3G. At the same time, the wireless mesh network can also rapidly develop based on the Wi-Fi terminals that have been accepted by the market. Technically, wireless mesh networks, Wi-Fi, and WiMAX can complement each other to form a wireless MAN. Wi-Fi occupies the terminal LAN access market at a low cost, and WiMAX can be used as a fixed access point within the city, the wireless mesh network can implement the mobile broadband communication network within the urban area. Of course, with the continuous development of technology and the market, the wireless mesh network and the future 802.16e and 3G will indeed overlap on the business layer, which will also bring about some competition, however, we can conclude that the complementarity between them is greater than competition.
