Introduction to the new concept of bridging

I believe you have some knowledge about wireless bridging, so I will introduce you to the Wireless Distributed System (WDS. It also has the bridging function, so how is it implemented and what principle is used? Let's take a closer look.

Introduction to Wireless Distributed System (WDS)

WDS (Wireless Distribution System), a Wireless distributed System, is a part of the 802.11 Network Used for relay bridging.

The wireless distributed system transmits wired network data through the wireless network as a relay architecture, so that network data can be transmitted to another wireless network environment or another wired network. Because a virtual route is formed through a wireless network, it is called a wireless network connection function. Strictly speaking, the wireless network connection function usually refers to one-to-one, but the WDS architecture can be one-to-many, and the bridging objects can be wireless network cards or wired systems. Therefore, WDS requires at least two APs with the same function. The maximum number of APS depends on the architecture designed by the vendor.

What is the universal WDSUniversal WDS mode?

It is an enhancement to the original wireless distributed system mode. It does not require the remote AP to have the WDS function, so it can be used on any wireless device. It also supports 802.11, access functions, encryption technology, and service quality.

Application Advantages of General WDS

For a common wireless distributed system device to achieve remote wireless connection, both APs must have the WDS function. However, the earlier wireless device only had a single AP coverage function and did not have the WDS bridging function. To bridge the two AP servers, do we need to discard the previous devices and buy two new devices? This is undoubtedly a waste of resources. The common WDS mode is supported by the middleware wide Wireless AP to solve user problems. In this way, the flexibility and convenience of the entire network structure are greatly improved, so that wireless network builders can purchase as few wireless devices as possible to achieve a variety of connection networking projects for the wireless LAN and reduce the network cost.

How does General WDS work?

The general WDS mode works in the MAC physical layer like the Wireless Distributed System. The two devices must configure the MAC address of each other. WDS can be connected to multiple APs, but the peer MAC address must be correctly configured, and the peer AP must be configured with the same channel, such as Channel 1, 6, and 11) and the same SSID.

The Wireless AP that supports General Wireless Distributed System technology has a hybrid Wireless LAN working mode and supports wireless access points (Wireless AP or wireless route) in point-to-point, point-to-point, and relay application modes ), it also works in two working modes: Relay bridging mode + AP mode.

Application Environment

For different wireless antenna application environments, we need to select different antennas. When long-distance communication is required, some Wireless AP antennas are in the room, while some are outside. Therefore, select indoor or outdoor antennas suitable for different environments as needed. It should be noted that indoor antennas have not been used for waterproofing and lightning protection. Therefore, indoor antennas cannot be used outdoors.

Coverage

When you need to transmit data from a long distance, you should select an antenna with a large gain. For a wireless network with a short distance, you can select a small gain antenna or use its own antenna.

Generally, large-gain antennas are suitable for long-distance transmission, while small-gain antennas are suitable for network roaming and other applications that require large coverage.

As a universal wireless distributed system function, the Wireless AP product of CIDR can not only perfectly implement the WDS function, but also provide wireless coverage, it also supports wireless bridging with another LAN within a certain distance, and does not require remote AP to have the WDS function. Most users want both the fish and the bear's paw.
