Wireless Network Because of ease of contact, binding of relatively small, so more and more enterprises and units. But I believe that the advantages of wireless networks, although there is, but it is with the cable Network Compared, there are still a number of inherent flaws. This author believes that wireless network at least in the short period of time, not able to completely replace the wired network. When necessary, wireless network and wired network should coexist, complement each other. However, some enterprises, is too superstitious wireless network technology. Even comp letely abandon the existing cable network, and all upgraded to wireless networks. I believe that such behavior is not desirable. According to the author many years of network design experience, I believe that, at least in the following areas, but also the existence of cable networks. First, the application of critical Server And routers and other network equipment connected Now deploy the application server is often connected to the router or the server Switch , While the router or switch and then connect to the client. At this point, if the server and use the wireless connection between the router, then it may be a connection between them will be the application server performance bottlenecks. Because most of the Application software Are present and distributed access problem. At this point each client like a brook, brought together through a router, the flow of the application server. If the application server and the narrow channel between the router, then these gathered up the stream, the river could fit. At this point may cause network congestion, thus affecting the performance of application servers. Under the same conditions, the wired network speeds much faster than the wireless network, but also more stable. Therefore, if the application server and a router connected between the cable network replaced the words, as if the application is to expand the channel between the server and router, the river changed to Jiang. Then the stream can accommodate more. At the same time, the amount of data transmitted over wireless networks of more than. And the server is on the side of the general, it will not always move. To this end there is no need to deploy wireless network connection. Therefore, I believe that at least some of the key application servers and other network based connection between the Oracle database server and router such as the connection between the existing technical conditions, the cable networks have value of its existence. In the short period of time, unlimited network technology can not replace wired networks. 2, wireless access point and router, the connection between If you want to deploy wireless networks, then Wireless Router (More professional statement, called the wireless access point) is essential. But businesses often need a border router, to connect Wireless LAN And the Internet. In other words, companies often through means such as fiber or ADSL dial-up, through a router to connect to the Internet. Then deployed in the enterprise wireless access point, on the one hand connected to a wireless client, the other connected routers. The question now is, wireless access points and routers how to connect? Now most of the wireless network, is used in this wired connection, that is, between the wireless access point and router is still so wired via Ethernet cable to connect material. This is the most important reason is because of bandwidth considerations. If using a wireless network, then the same number of clients within the cell is difficult to control. There may be only one client within the cell may also be within a cellular contribution has 100 clients. Although the size by adjusting the cell can properly control the number of wireless clients. However, the intensity of the control cable is far less strong. Wired network, then an interface is only able to connect a host, unless they use the other switches, Hubs Equipment such as extension. And the wireless access point is still mainly used to share bandwidth mechanism. End, wireless access points and routers, often have to provide higher bandwidth to meet a lot of common access to client needs. That is, using wired network connections to improve the wireless access point and the wired network connection between the very, very necessary. Third, relatively high cost of full replacement If an enterprise network upgrade from wired to wireless networks, in addition to configuring the wireless access point and other equipment, the most important item of expenditure may be equipped with a wireless network. Because the previous company to buy the mainframe, most of them are desktop computers. The desktop computer, then, by default, is not equipped with wireless cards. That is, if the business needs of all clients are upgraded to wireless clients, then it must be for each desktop computer with wireless card. However, this investment is not small. Then have that a necessary? I believe that in addition to taking this to show off and fill the pockets of outside suppliers, there is no use. Wireless network connection mainly designed for mobile office. That is, unless you want to walk around holding a computer office, then the client will use the wireless network has relatively large value. But while carrying desktop computers, office walked a total of not very realistic, right? To this end, I believe that desktop computers such as the relatively stable position of the client computer, t here is no need to spend this money trying to give them wireless LAN. Wireless access point uses a shared bandwidth approach. That is, the efficiency of wireless access points with efficiency similar to the hub. When the number of clients more time, each client will be able to enjoy very limited bandwidth. The cable network, then, is different. This is related to the bandwidth of cable is that the client exclusively. Therefore, under the same conditions, the performance of wired networks much higher than the wireless network. At this point, go to the desktop client to upgrade to wireless clients, money down, and performance not only failed to improve, but declined. And desktop computers and inconvenient, they do not enjoy the benefits of convenience. Network administrator is not fed nothing to find things to do? It costs or from the nature of both
