Network cabling system is still very common today to tell you about the principle of network cabling systems, analysis of how it "work" and also discussed the prices of network cabling system problem, I believe it is useful for everyone.
Whether the office, small and medium businesses or home computer or need to share more of the neighborhood, more than one network is a required course for computer applications.Will link more than one or even dozens, not only at any time can share files, printers and games, and more machines can share a broadband line surfing the Internet, thus saving money.To conduct multi-machine network, there are two common ways of networking - wired and wireless.To use the wired network cable, network cable to connect it through computer or other equipment; and wireless networks in addition to the same cable broadband connection is required, the progress can be completely without computer networking cable.Which of these two approaches is better? Which is more suitable for you? Here the writer to analyze.
In order to facilitate everyone to know, here we have from the principle, prices, etc. look.
◆ Principle
Integrated wiring system through the wired network using a network cable and network equipment as a medium to achieve network cabling system (implemented using only one cable is not connected double within the scope of the discussion.)Twisted pair cable network is generally used in household as the transmission medium, characterized by the operational stability of affordable and high security.Wired network selection method is required before formation of well-designed network topology and the actual position of the alignment, because the care of the aesthetic factor, Buried way cable network cabling is generally used, but this method is vulnerable to environmental constraints at home and change the network structure of the futureto bring trouble, so best to be realistic before the formation of the environment and the future need to adjust the factors to be considered.
More suitable for wireless broadband routers do not want to home networking for network cabling system users, home wireless broadband routers also typically provide four LAN ports, you can achieve wireless and wired network seamlessly.But the networking for the environment are higher, better shielding or distance connection, the signal coverage and strength will be a corresponding decrease for this, we must choose the signal transmission capability,Connect the product to ensure stable performance cabling system connected to the network smoothly.
◆ Price
To facilitate comparisons, the following to the market price for the same product with lower, for example, to look at the formation of a range of about 30 meters within the 10 inputs required for the computer, you can compare the selected products which put less.
A machine wired network requires:
Broadband Router (100) + wiring and crystal top (total length of 10 meters in total, 10 million) + other costs, such as wire through walls and equipment (10 million), totaling 120.
1 machine wireless network needs:
54M Wireless Broadband Router (160 million), the notebook is now largely integrated wireless card, totaling 160.
3 machine wired network requires:
Broadband Router (100) + wiring and crystal top (30 meters in length total, 30 million) + other costs, such as wire through walls and equipment (20 million), totaling 150.
3-machine wireless network needs:
54M Wireless Broadband Router (160 million), the notebook is now largely integrated wireless card, totaling 160.
10 machine wired network requires:
Broadband Router (100) +8 port 10/100M Ethernet switch (80) + wiring and crystal top (total length of 100 meters in total, 200) + other costs, such as wire through walls and equipment (50), totaling 430 yuan.
10-machine wireless network requires:
54M Wireless Broadband Router (160) +5 Block 54M Wireless LAN (only counted five card input, the other for the board or computer integration, 100 yuan each, a total of 5 500 million), totaling 660.
You can see out, if you use the integrated wireless card in the laptop, then the more the cost of the computer less.Set up 10 local network.In addition, the cable network cabling system for the selection of the cheapest switch SOHO-class switches, to select enterprise-class switches, then surely the cost will double or multiple.Not not know, a count was clear, set up 10 wireless and wired local network investment less the same, in the majority of users within an acceptable range, up from a price performance ratio measured cable network cabling system has little value can be used.
