Introduction to wireless relay instance applications

Although the wireless relay mode has a high cost, its advantages are still adopted by many network construction methods. Next, we will introduce the application of the wireless relay mode in the actual network construction of wireless networks. Go to the following link.

Establish network connection in wireless relay Mode

You can build a relay Bridge in two ways. A single bridge is used as a relay and two bridges form a relay point back-to-back.

A single bridge can be connected to two antennas through a splitter. This method is very simple and practical for users who are not very sensitive to bandwidth due to the shared bandwidth of two-way communication.

Wireless Network connection for a single AP as a repeater

Users with high bandwidth requirements can use two backto-back bridges in different frequencies to work in the wireless bridge mode. Each wireless bridge connects an antenna to form a bridge relay to ensure high-speed wireless link communication. The two back-to-back APS can be in different frequencies and work in the wireless bridge mode at the same time, so that their functions can be expanded and the signal can be maximized during the forwarding process. Increase the bandwidth and speed to the maximum, so as to meet the high requirements of users, to ensure their smooth degree.

Two AP wireless network connections for relay

If the two networks to be connected are too far away or have obstacles in the middle, relay AP is used to connect the networks. When purchasing AP devices, note that not all APs support WDS. At the same time, we also need to see the transmit power and antenna gain parameters. The unit of AP transmitting power is dbm, and the unit of antenna gain is dbi. The higher the two values, the stronger the signal penetrating power of wireless devices.

The transmit power of a Common AP is below 20 dBm, and the gain of the antenna is between 2 and 2 ~ Within the 3dbi range, according to experience, the 2dbi gain antenna signal can penetrate two walls. There is also a shared network. The entire WDS is equivalent to a large network. The more users, the lower the bandwidth each user receives. It is best to buy a uniform brand of wireless devices, select the bandwidth device based on the actual situation. In the end, we still need dedicated targeted antennas on the online, so we need to take protective measures such as waterproofing and sun protection.

Wireless relay coverage points are usually composed of two AP modules, one of which uses the SAI mode working client mode). As a signal receiver, the AP receives the wireless signal of the previous station, the other AP uses the standard AP coverage mode for wireless coverage. In this way, wireless signals can be relayed one station at a time to form a wireless relay. On the other hand, each station can achieve local coverage. In this mode, network signal amplification and continuation can be achieved, solving the problem of distance for network formation. This makes wireless networks more widely used and makes it possible for many users who cannot use wired networks to enjoy the Internet.
