"Wireless network communication" has been regarded as the representative of High-tech technology, but also many people think that a small number of rich can enjoy the special services. In fact, the rapid development of the IT industry, the increase in personal computers makes "wireless network" become a lot of civilians, without the amount of silver can build their own wireless network. Now we're going to introduce how to build a corporate wireless network.
First of all, we have to understand that wireless LAN and the past based on cellular telephone network, private packet switching network and other technologies of wireless computer communication, there are many differences in nature. Wireless LAN must support high speed burst data service, which includes multipath fading and crosstalk between neighboring subnets in indoor use. It can use radio or infrared as the transmission medium, using the extended spectrum technology, mobile terminals can access the Internet through the wireless access point.
Of course, the most important thing is to have a home access to the broadband line, and then connect this broadband line to the wireless transmitter AP, and then on the computer need to install a USB port or PCMCIA wireless network card.
The following is to set up a wireless network node, the role of wireless network node is the cable network signal into the wireless signal, its location determines the entire wireless network signal strength and transmission rate, positioning is very important.
First, the wireless AP and LAN computers do not cross too many walls, especially reinforced concrete walls. This can greatly weaken the wireless signal strength.
Second, because the wireless signal is transmitted in a straight line, if there are obstructions in the middle, the wireless signal will be weakened part. Therefore, the location of the wireless AP should be relatively high.
Third, wireless AP should be located in the center of work or use location. Because the wireless AP is covered by a circular region. The closer the wireless AP, the stronger the wireless signal, the greater the anti-interference ability, the higher the transmission rate.
Through the above steps, the formation of a wireless transmitter to the AP as the center, the wired network signal into the process of wireless signal, that is, like a radio transmitter, control the entire wireless network radiation computer Wireless LAN, so it is the core of the entire wireless network.
Most wireless routers in the range of signal coverage can support the use of larger office areas, coupled with the introduction of some auxiliary technology (such as: domain, MIMO, 2XR and other technologies) to enable the product in the signal coverage and strength of further enhanced.
In the Enterprise office use, the demand for wireless routers is relatively higher. The upper and lower floors of the office area, as well as the independent Office environment requires the wireless router to have a strong signal output rate and strong signal penetration. Therefore, the output signal is very important for the penetrating ability of the barrier. The wireless router, which has powerful signal transmitting power and security of user data, should be the choice of small and medium-sized enterprises.
I am here to "Cisco Linksys BEFW11S4-CN Wireless Router" as an example to introduce its specific settings.
As the world's leading network equipment and solutions provider, Cisco Linksys has focused on Soho and home markets, BEFW11S4-CN has a 10/100m RJ-45 port for connecting to broadband modems, four 10/100m RJ-45 Exchange port and a shared uplink port.
After installing the driver, enter the default account and password in the admin login menu to enter the AP's settings management interface, after viewing the wireless network node's instructions, it's IP address is 192.168.1.1, the subnet mask is 255.255.255.0. In the network properties, the IP address of the computer wireless network adapter is set to 192.168.1.2, and the subnet mask is set to 255.255.255.0, keeping it in the same network segment as the wireless network node. Typically, a wireless network node that is not set up is unencrypted, and you may be prompted to "connect to an unsecured wireless network" when you connect. Confirm the connection first, and then secure the security after the wireless LAN connection is successful. After a normal connection, the current signal strength is displayed in the network properties.
