The so-called wireless network is a network that interconnects various communication devices without wiring. Wireless network technology covers a wide range of technologies, including both global voice and data networks that allow users to establish long-distance wireless connections, as well as infrared and radio-frequency technologies that are optimized for close-range wireless connections. Depending on the network coverage, wireless networks can be categorized as Wireless Wide Area Networks (WWAN: Wireless Wide Area Network), Wireless Local Area Networks (WLAN: Wireless Local Area Network), Wireless Metropolitan Area Networks (WMAN: Wireless Metropolitan Area Network), and Wireless Wireless Networks (WMN: Wireless Metropolitan Area Network). Network), Wireless Local Area Network (WLAN: Wireless Local Area Network), Wireless Metropolitan Area Network (WMAN: Wireless Metropolitan Area Network) and Wireless Personal Area Network (WPAN: Wireless Personal Area Network).
Features
1, mobility, can break through the limitations of time and space.
Wireless network is through the transmission of radio waves to transmit network signals, as long as in the range of the transmission, people can use the corresponding receiving device to realize the corresponding network connection. This is a great way to get rid of the limitations of space and time, which is not possible with traditional networks.
2, network expansion performance is relatively strong.
With the wired network is not the same as the wireless network breaks through the limitations of the wired network, people can access the Internet at any time through the wireless signal, the network expansion performance is relatively strong, can be more convenient to realize the network configuration and expansion of the user to access information will become more efficient and convenient. The wireless network not only expands the spatial range of the use of the network, but also improves the efficiency of network use.
3, easy to install equipment, low cost.
Usually, the process of installing wired networks is more complex and cumbersome, wired networks in addition to the layout of a large number of wires and cable connectors, and its maintenance costs are very high. The wireless network does not need to lay a large number of wires, the installation of a wireless network transmitting equipment can be, at the same time, this also creates a very convenient conditions for the maintenance of the network, and greatly reduces the cost of the network pre-installation and maintenance of the cost of the latter part of the cost.
Compared with the wired network, the main feature of the wireless network is to completely eliminate the limitations of the wired network, the realization of the wireless transmission of information, so that people are more free to use the network. At the same time, the network operator is very easy to operate, first of all, the line construction costs are reduced, the operating time is shortened, the return on cost and profit production is relatively fast. These advantages include improved management of wireless information transmission by administrators and greater flexibility for users with no space constraints in the network.
